hi,i'm building a DH-2 from scratch. i wont be useing any laser cutting just a table and scroll saw plus the usual hand tools. this plane will have a fully working cockpit and even the knome motor will spin with the electric motor. this will be a highly detailed museum quality build.i thought about useing fiberglas for the front of the fuse or even wood laminations over a skeliton frame. after alot of heming and hawing i decided to vacuform the piece. it's a very formidable piece to produce with all it's compound curves. i'm going to form it in 2 pieces as my vacu system is only 10"x10" and then glue together, fill and sand. i'll be useing very thick 0.60 black styrene. i made the plugs out of very hard balsa. i always put a car wax or silicone wax on the surface of the plugs and buff them out when they are complete. i use a little talcum powder on them just before i form the plastic over them. i used litho plate and small rivets for the banding. here are a few pics of the work so far.

i got some more of the fuse done and also framed up some of my tail feathers. i cut my struts from spruce and finished them so they will be ready when i get to that point. i also installed the rudder bar, i have a small etching tank and besides making brass or stainless parts from scratch i also design them on my computer and etch them which intails takeing the artwork to film on my printer and exposing the metal to U.V. light that has been coated with photo resist. i will be etching a lot of parts for this build. i'm working with p. neate plans. here are couple more pics of the build so far.

thought i would post a couple more pis of the inner workings such as the rudder bar, servo deck and control stick. i could not find for the life of me any thing on the net as far as a close up of the control stick. i do know because of the placement of the horz. to the elevator horns and from what pics i do have that the stick has to pivoy left to right and a solid placement foward and reverse to control the elev.. so i got left to right covered for the alierons but how do i get elev. movment with out affecting the alieron shaft and keep it from going up and down. i'm not sure if this is the way they did it in 1916 but it works and works well and as i see it there arn't to many ways to do this plus at 1/6 scale you don't have alot of room for a cockpit that works so i built a minature universal so to speak. so i hand cut all the parts and silver soldered every thing together and it works just fine, you'll see when you look at the pics.

first i'd like to thank everyone for there compliments and i have another batch of pics of the build progress.i started some of the grommet work on the sides. i did this by useing 1/64 ply as a stiffner and predrilled holes in the ply then i wrap and seal in solartex leaving a 1/4" tab. useing a soldering iron i then burn holes through the solartex where i predrilled and then set the brass eyelets in and then useing a tool i made i tap the reverse side and expand the eyelet to anchorit in place. i decided to keep everything in brass and not paint anything, it seems to be a nice change. i have about 75% of the cockpit detail done, a little more instrumentation and a few other things and will call it done. i also built a wicker seat it took about 12 hrs to design, cut and weave it. the seat cushion is in tan leather, all the leather work will match the seat. well that's all for now i'll keep you updated on the progress.

thanks Chellie, i do think 99% of the folks on this forum no more than i ever will. ive only done 2 kit builds and this is my first scratch build,actually my second, my first was a 1/7 scale fokker dv11 and the plans were so bad i ended up smashing it to smitherenes. but ive come to learn that if the plans are not of a kit build you have to think outside the box and 20 steps ahead in otherwords if you cut a part from a plane and think it going to fit like a glove or at all for that matter your in for a rude awakening and this just shows how naive i am and how new i am at this hobby( less than 2 yrs) but i'm learning. as far as modeling i must be a natural. in my whole intire life i probably built 3 plastic kits and thats when i was ten and was a long, long time ago. i started this hobby and fell in love with it and seem to like the building more than flying. at a time when there is very little creative challenge at least for me it's been a life saver. anyway enough with the bio, some more pics of the progress. the cockpit is all finished and i also handstitched the combing on to match the seat cushion and i framed up the tail feathers. i built the LG out of brass tube with the apropriate size music wire running through them for strength. the same for the hardwood legs, i made them solid then i made a drill bit 7 inches long and put a hole all the way down through them so i could insert music wire and weld them to the mounting stud. i'm starting to scratch build a 7 cylinder gnome. the only thin i'll be useing that were made already are some cylinders from a 1/6 scale WB lerhone which i'll modify to represent a gnome cylinder.

Tim hi tim, i use basic hobby tools, exacto knife, jewelers saw etc. for alum. i hand cut every thing with exacto and i use litho plate that's about 0.13 to 0.15 thick score and bend sand and smooth. to get shape i tack on a template on paper output from corel graphic program. i use corel for every thing, i find it easier than my cad programs and it does basically the same thing. now the big question " brass" and if you happen to catch on the first page that i etch all my brass parts. about 6 months ago i purchsed a small etching system from micro-mark, they have a incredible site for online hobbiest of all types. anyway when i found out how easy it was to do etching in your basement it blew me away. since then ive really mastered the process by getting a bigger tank and adding citric acid to my ferric chloride and little things like that to make it faster and also makes your etching solution last longer. i still purchase all my chemicals ferric clhoride, sodium hydroxide, photo resist which covers both sides of your metal plate ( stainless steel or brass) and inkjet film from micromark.com . here are a few pics of the process and you can also make 3 dementional parts or write by scoring or writing some verbage on one side of your film this way it only etches part way. i forgot to add that my stainless steel or brass ranges from 0.05 to 0.15 in thickness, the thicker it is the longer it takes to etch and i wouldn't put anyting thicker through my laminator.

Looks like a fish tank and air stone. yes it is a plastic fishtank and holds a 5" piece square of brass opposed to micromark's plastic tank and ive since moved on from air stone to a custom airiator that i use. the stone breaks down and desinagrates after 5 or 6 etchings and my new one has more thrust to make things faster. you definitely want to go with plastic or glass or plexi thats glued together, NO METAL like glass tank has holding the corners together plus anything that's glued together has to withstand the heat from your ferric chloride, you have to heat your chemical just below boiling it makes the etching faster and cleaner that's why i chose a molded tank to eliminate some of the variables some day when i have the money i will go with a lexan or plexi with the special glue and also a ceramic heating element so i would never have to take the ferric chloride out except when it gets bad,( to many etchings) and pour some fresh stuff in. micromark.com gives you a plastic tank that's 3 1/2" square by 10", it's tall like a quart of milk that's so you only have add 16 oz. of etchant to get the desired depth

i finally finished my 7 cyl. gnome. i just about scratch built the whole thing. for one thing you cant find a gnome in 1/6 scale but do believe WB sells a 1/4 scale cylinder. so i scavenged the net for reference material, ( ther seems to be quite a few versions of this engine) and started building. the crankcase is made from 1/16 ply laminated with 0.10 stainless steel. i used some existing cyl. i had left over from my newport 11 build. i had to make a 1/5 scale( which they dont make) out of two 1/6 scale lerhone kits, that was a challenge i was newer at this than i am now. back to the knome i cut the head off the cyl and a little nip and tuck here and there.every else i etched in brass and stainless steel. the new heads are all soldered together and were made from 3 brass circles from small to large with 0.15 thickness all notched and stacked. all the 3-D were etched flat with a score line etched on one side for easy and clean bending into it's form. the crank cover etc. is stainless steel backed by 1/16 ply lamed together. the engine also spins at about 1/6 the overall rpm and seems to look relly good no wobble. i did this by fluting the inside of my mount and the engine crankcase so it basically pinwheels at about 1000 rpm and seems very balanced with my out runner a 35-48-850 rimfire with a 70 amp speed controller. i think if i hooked up the dummy motor with the outrunner the torque and kv combined would have been to much, gnome parts flying every where, duck. talk to you in a bit.

Not sure how I missed this build. It's stunning just like your others. Nice to see you back at it. We really apreciate your talent, and are glad you share it with us.

What I'd really like to see you do is learn to fly (and maiden) your planes yourself. Many hand their planes over to the local "expert" for maidens, (and at the field that I go to, this is a positive thing, because the "local expert" is just that - a very good pilot). While others like me, learned on simple cheap planes. I learned with a 3D Tiger Moth - completely self taught. I know you enjoy building more than flying, but flying something scale really brings a whole new level to this hobby. I'd love to see you learn, and crash, a couple cheap simple planes. Then move up to a balsa ARF like Great Planes SE5 or DVII. If you crash those, fix them, and fly again. Once those are mastered, move on to your masterpiece planes you've built.

Nothing would make me happier to hear that you've learned to fly, and have had this plane up and back down in one piece.

I was thinking the EXACT same thing! And now, after reading a few more posts forward, I see the whole story. I don't care WHERE you post, so long as you keep on doing so. Your astonishing patience and skill are a treat to behold. The fact that more than one of us recognized your work instantly is a very sincere compliment. You're raising the bar for us all ...well at least those who still have the guts to even attempt scratch building after seeing your work. (I know a few ex-writers who have been crippled by Cormac McCarthy.) ;-)

Question: Are you working from published plans on this one? I'm in the market for a set (AMA has some that I've inquired about, as does Arizona Modelers and Kit Cutters) and I'm trying to decide which to go with. Anyone else out there have an opinion?

This is a truly beautiful aeroplane, if you are serious about selling it to someone who will appreciate it I would try to get in contact with Peter Jackson (from lord of the rings).

If I saw a photo of this plane sitting in an empty field, I would think it was the real deal. Absolutely astonishing amount of faithful attention to detail.:) Fantastic job!

Amazing build with fantastic scale.
Just a small point but the cam case on the Gnome Monosoupape looks to be too small.
Depending on the model of the engine it actually stuck out quite a bit with each push rod entering at a different position.
This first illustration shows an early Monosoupape that had 9 individual cams in quite a big cam case with each push rod entering at a different angle.
The second picture shows a later version that I think only had 3 cams (but geared to go round at 1/2 engine speed?) and thus a rather smaller cam case with the push rods at only 3 different positions.
But you did say "museum quality"!

Looks like each rod had its own lobe on the cam shaft.

Do you know if the firing order was in-line, alternating or simultaneous?

quorneng

The firing order was 1,3,5,7,9,2,4,6,8.

dbcisco

That order looks like it had four two lobed cams. The rods would have been in a pattern of four pairs each pair having its own position on the cam shaft/cylinder.

edit: make that three on three lobes.

Simon yes i did say museum quality, you got me there. what happened is i needed to compress the depth of the engine because i only had so much room even with the shaft ext. so i had to cheat a little bit. i found so many different versions of this plane and it seemed to change considerbly from the early 1916 to the latter 1917. don't beat me up to bad Simon i'm fairly new to rc modeling and sometimes you just have to make things work, thanks for your input.

I guessed that was probably the reason.

Just as an aside I am looking at the possibility of burying an out runner completely inside the crankcase/cam case of a scale rotary.

iv'e finally finished my bird with the exception of the airco logo's that go on all the struts. i made the four bladed prop out of cherry and i have to say it was a bear, but its done and didn't come out half bad for someone who has never made a prop before. i also had to make brass clevises, there all hand cut and silver soldered. with a plane like this every thing has to be tensioned. the rondels and #'s are super thin decals i made, there a pain in the butt to apply but when all is said and done they almost look like paint. everything works in the cockpit and the gnome spins with the prop etc., i'll be posting a video of all the functions very soon until then here are a bunch of pics of the DH-2 in all it's glory. i'd like to thank everyone for your compliments and support.

I have thought long an hard about even raising this but I cant find any reference to a 7 cylinder Gnome ever being used on the DH2.
Surely it was either a 100hp Monosoupape or a 110hp Le Rhone and they were both 9 cylinder or have I missed something?

Excerpt.
"Most often attributed to the American F.D.Farwell the rotary engine may have had an earlier beginning in a compressed-air engine worked out by the Australian pioneer Lawrence Hargrave some eight or nine years prior. It is certain, however, that the French brothers Seguin brought the engine into commercial and mechanical life based on the conceptions of one brother (Laurent). It was in 1907 that his 7-cyl rotary was born - and it came to be known as the Gnome. This engine was followed by a succession of designs by many manufacturers, most of which were successful."

DCFlyer, you are one of the most conscientious builders I have yet seen. Most people would be affronted by someone questioning their build- even if true. Kudos to you for your honesty and graciousness to quorneng's information. I am repeating myself, but the effort you have put into this model is stupefying (guess I wasn't out of superlatives after all!;)). I hope you will continue to post your build projects.

Exactly - lot's of ruffled feathers in this hobby at times - nice to see someone say "dang, missed that - I'll fix it"

can some one please tell me how to upload a video?

What have you done with the video? Is it posted to Youtube? Or Vimeo or some other sort of host site? If not, you'll have to do that first. If it's Youtube, you'll notice the black and red logo in the upper right of your edit window when posting a new message. Go to your Youtube video, and notice in the URL there is an "=" (equal) sign in the address. Copy everything in the URL that is to the right of that equal sign. Then, when editing or creating a message here, click on that YouTube icon. It will then look like this...

[ YOUTUBE] [ /YOUTUBE]

Insert your coppied URL (the part to the right of the equal sign) inbetween the brackets of the above YOUTUBE lettering.

DC-- I can only add to the compliments already paid you. I followed your precious builds on the other site and was disappointed when the posts ended. Glad I found you here. Now I have a reason to get up a few minutes earlier before work and read your postings over a hot cup of tea before a depressing 12-14 hours of labor.

If anyone has contacts at the Smithsonian steer them towards this man. Unbelievable quality and realism. Now I have to search here and see what you're on to now.

DCFlyer,
I'm not John Travolta, but have you considered accepting private commissions or even ebaying some of your existing work? While it may feel a little alienating, I do believe that this level of work might fetch thousands if not tens of thousands of dollars. Crating and shipping might be an issue but nothing compared to what you've achieved in that spad for example.
Leo

i'm shooting for between 6 1/2 lbs to 7 lbs. yes exacty what i think and how i feel about my work. it is art to me 3 dementional art especially after youve invested 1200 to 1300 hrs in a build. as far as flying , all my builds i tried to do something different like the 1/6 scale DR1 with a robotic pilot that actually mans and flys the plane with the controls, although it hasn't been test flown. did some taxinging and a few little bunny hops but thats it. my DH-2 is my most involved indeavor yet even though i put that level of detail in all my planes with every build i get better, more ideas etc. so fly it? i'd think i'd rather sell it to a collector or museum. i'm trying to get in touch with john travolta i know he has a place up here and is an avid flyer of full scale planes and loves areoplanes the way we do, now how i go about doing that is another question but i know he'd love to hang it in one of his many rooms and would appreciate it, now if there are no takers i will probably get around to flying it with the help of a knowledgeable person to help me trim and ready the plane and also pilot it then will do a maiden. thanks for asking.

Leo i'm always interested in selling, even at a loss otherwise all they do is sit around and collect dust. i would would like them to go to someone who can apreciate the work and time and unrelenting devotion
that went into creating this aircraft. it's been a labor of love for sure and if the money is right crating is not a factor. thanks

my beautiful DH-2 was in the back of my rav with the seats folded up and some jack off cut me off and had to lock up the brakes. any way both of the seats came out of the locking mech. and down on 1200 hrs. work, i almost cried. it may not look to damaged but it's not repairable if you look it's warped in every concievable way, from the frame to the wings, landing gear and so on. maybe i'll build something else to replace it as of now i'm going to strip down for parts, thank you all so much for your support and encouragement on this build.

This is sad news indeed. Please, before you scrap it, walk away and come back with fresh eyes. All damaged aircraft can be repaired, but sometimes emotion gets the best of us. You might find it worth repairing after all.

So sad to hear of this...Especially since this isn't the first that an untimely accident has happened to one of your wonderful creations! I am sure that all of us here can empathise with your pain...although I doubt few have so much time involved in a single build.

Just to relate to your pain...I had a Corsair meet a similar situation. This was actually my third plane I had built...merely a GWS foamie I just glued together...I did spend a bit of time and $ researching Corsairs and trying to get just the right colors for her (not nearly the level of mastery of detail and craftsmanship that you you have achieved mind you).

At any rate, Several years ago I was en-route from work to home hoping for an early morning maiden. Some "jack" cut me off causing me to slam on my brakes! Well... All of the contents in the back of my Cherokee slid forward... all I could hear is the sickening crunch and cracking behind me. Yup, this was the crushing of my poor Corsair (and a Spitfire)! After rebuilding, the Corsair ended up being the best flying plane I have had!

As has been mentioned before...let her sit for a bit...then take another look...maybe things aren't as bad as they seem. I know that you are sickened and quite peeved at the situation, but perhaps a bit of time away will freshen your thoughts on this plane.
After all, the real planes didn't live charmed lives themselves now did they? Unfortunately a lot of pilots and soldiers didn't have a very high survivability rate either.

Maybe this is your chance to work on your flying :tc: If I remember correctly, you don't have much experience flying...nor do you have a trusted friend to fly for you (DR.I ?) So here is your chance! Take all the details off....lighten this baby up and give her a go.... before you toss it in the bin! If not, I am certain someone here would be happy to give her a good home!
