Default $100 Scratch Build Contest "Best Looking" poll here

Its on....Please read the full set of rules, and lets all have fun.




1. The goal of this contest is to get a plane in the air for $100. Each part must have its source and replacement cost listed.

1A The replacement cost of ALL components will count towards the $100 total, even if they are free samples, used, rescued, recycled, scrounged, liberated, souvenired, or stolen.

1B. If a contestant uses a small quantity of an item that is usually bought in bulk, then only the amount used needs to be counted. Examples include, but are not limited to: covering material, dope, Styrofoam, and epoxy. The source will still need to be listed, and the cost of the “bulk item”. For example; if a contestant used ¼ pint of nitrate dope that cost $40 a gallon, he should list that expense as $1.25, and list the source.

1C. Shipping, Handling and taxes do not count towards the $100.
(see posts 15 & 16)



2. The entry may be built from personally designed plans or plans from any source or from a precut balsa and ply kit, composed of elemental pieces. No ARF's or ARC's (Almost Ready to Cover) will be allowed. No foam kits, such as the GWS type kits, will be allowed. Preformed canopies, cowlings and small trim pieces may be used as desired. No major components can be “factory made”, nor can they be “recycled”. Major components include, but are not limited to wings, fuselages, and tail feathers.

3. One of the goals of this contest is to encourage new folks to build. In keeping with this goal, there must be at least 10 assembly pictures in the build thread.


4. The power system must, of course be electric. Since this is not a scale contest the plane can look like anything you want.



5. The contest build should begin on or after 11 March 2011


6. The build must be completed and flown by 8 May 2011

7. A build thread must be created for each entry. A contestant may enter as many times as he/she wants, but he/she must have a different build thread for each entry. If a contestant does enter multiple times, each different build thread must be for a different aircraft. (You can’t build 10 “Capricorns” and have 10 build threads/entries) Links to each build thread will be entered in this thread. Before judging, all comments not posted by the builder will be removed from the build thread, at the contest moderator’s discretion. Be sure to include $100 Scratch Build Contest at the beginning of your thread title. Also, you must state in the first post whether you are building from plans or from a kit.


8. Build materials will be builders choice


9. Planes entered will be required to fly successfully. Proof that your design is capable of flying will consist of a video, or at least 3 flight pictures posted in your build thread. If you are not able to provide proof that your entry is able to fly, your entry will be disqualified.


10. Voting will be held from 8 May 2011 to 14 May 2011. Each entry can receive votes in the following categories:

Best Looking

Best Flying

Best build thread


Each person voting will get to vote once in each category, for a total of 3 votes. The votes may be spread over 3 different builds. The build with the most total votes will be the overall winner.


If you are not able to provide a flying video, you won’t be able to receive any votes in the Best Flying category. This is sort of a bonus category to earn an extra vote for making the effort to post a video of your entry in flight.

This has started a little faster than I was thinking it would! Now I have some research to do. I need to make sure the project I had in the back of my mind could be finished for under $100.

I guess this means the research starts now!

If you do this, then HK or Hobby Partz should sponsor the prize money, and make it more than $100 to boot, since all the gear for the builds will end up being bought there anyway.

I've heard of clubs that have contests, where folks slam planes together from hacked foam, etc, and have a several hour time limit to build them. The less than master modeling quality results would definitely be entertaining.

Woot! Got my project picked out already. Need to do a bit of figgerin' to make sure I come in under budget. Think it should be pretty easy, if I can do it within the time constraint. I am one damn slow builder. John.

Do you need to include shipping in your cost estimates??

I am right at $100 with my initial plan when adding everything up based on costs I see on the web, but without shipping. It's all stuff that was already purchased and I don't want to actually purchase anything if I don't have to.

I've attached my parts list. Is this acceptable??

Steve

Im glad you brought that up. Since this is my ugly cat, Im gonna kick it. Shipping, Handling, and sales tax do not count toward the total. I think that most of us order in bulk anyway, and it would be very hard to keep an honest account of just how much shipping went with each item.

Chellie,

Watched the Katana video, looks good, especially in pink. Nice knife edge, my favorite flying attitude. Hover looks good. Great camera work, whoever did that deserves credit too.
I looked again, YOU are doing the video! Excellent!

Wow, lots of good info, just finished the foam cutting instructions from you, and that hot wire cutter can be had for $20 now.

I will be buried in your posts for the next couple weeks...and lovin it!

Back to reading, thanks Chellie.

That rifle is such a cool idea, did it help to make it pink? What can a guy do? A pink gun might get him in more trouble rather than less.... Ha ha

Thumbs up

I have to admit that I joined this forum as a direct result of seeing this contest.

I've been reading for a few months after becoming dissillusioned with the price of crash repairs on the both the Blade SR and Blade MSR helicopters I got around Christmas time.

My MSR motor gave out coincidently at about the same time I subjected my 3x 130 1S lipos to an unintentional deep-discharge. I didn't realise that it was the motor at that stage and set about finding replacement batteries. I found some at HobbyKing for $1.33 (vs $15.95 at my LHS) and promptly ordered a dozen. Upon receipt of my new cells it became apparent that there was still a serious problem.

After forking over $19 for the tiny gutless motor of the MSR I began to search for an alternative that would prove both more satisfying and far cheaper.

I waited until some Spektrum compatible receivers came into stock and set about ordering some parts for something I could both make and fly. Before the order even arrived, I realized that I'd made the mistake of getting the Spektrum compatible receivers so that I could save money and use of the TXs that came with my helis. Of course, both being cheaper RTFs they had non-programmable radios. That was when the penny dropped - they'll both have mixing programmed into them that won't be appropriate.

So I hit the HobbyKing site again and grabbed some more small supplies and a 6ch HK tx/rx.

I had a C20 1550kv, a Turnigy Plush 12A, some 8x4 props, prop savers, HXT900 and TGY1440 servos, and a couple of TGY Nanotech 850 2S batteries for good measure.


First, I thought I'd build a balsa profile from a foamy I'd seen on the web somewhere - Tiny3D. That project kinda stalled, and then one day at my LHS I saw a micro Sukhoi SU26 on the counter and again felt an urge to build.
I wrestled with trying to determine the cross-section from various 3-view photos I had, but like Tiny3D, this project stalled.


Around that time I saw the Slow Stick for the first time and loved the simplicity of the model. The only problem for me was that I didn't really want to go building something with a 4 foot wingspan first-off. I'd much preffer something about half the size. Upon searching for scratch-built Slow Sticks, I found Chellie's thread and somehow stumbled across Millenium RC's Micros SSX. Purrfect!

There's only about 50 parts and all seemed quite simple. So, I set about drafting up the parts I would need in a CAD program and gained an even greater appreciation for the creators of plans.


The build was simple - the hardest part was finding a surface in the house large enough to lay the wing frame out flat. I'm far too cheap (and love a challenge) to just go out and buy dope - but recalled seeing somewhere that (a) there was something called butrate dope and another called nitrate dope and (b) that both plastic covering films and some plastic wrapping paper films are polyester.

I bought some $1 tissue paper and some $1 plastic wrapping paper before trying my hand at sticking and shrinking the plastic with the iron. Uuups! I theenk that was a little hot. Oh well, I thought.

How's about this nitrate dope stuff. Hmm - seem to remember that table-tennis balls are cellulose nitrate that has camphor added to help plasticise it. So I cut up and dissolved 3 balls into about 100ml of acetone, waiting until the mixture was homogeneous (all the same, no lumps or thin bits)

I gave this stuff a whirl, using it to stick tissue to sheet. It seemed to work okay. Confident, I proceeded to assemble the tenderly cut-out parts, continually grinning at the jig-saw like quality that the parts all had. When it came time to cover the wing, I just used a Bostik GlueStick to stick the paper down to the balsa.

Finally! The big moment - will the ping-pong ball juice work or not? Working quickly, I was able to paint the whole top-half of the wing before the first panel had finished drying. I left the room for something, returning 5 minutes later to see a perfectly shiny, taut _shrunk_ tissued wing. Alriiight! Now we're in action. I gave the wing 3 coats in all and it sounded like a drum when I was finished.

Having finally finished attaching all the hardware 2 days ago, I set out for a maiden flight just as the light was really starting to shrink away. One of my axels pulled out when I nosed into the long grass about 3 meters after take-off. By the time I'd raced back inside the house and re-superglued it the light was in very short supply. (Foolishly) I continued on unpeterbed, determined to get my baby in the air.

This time I was more prudent with my application of the elevator and it shot straight up, reaching some 10 meters before my stunned thumbs could react and start to work out how to fly the thing and fight the wind. (Oh yeah, it was rather windy - perhaps not such a good idea) I brought her under control and managed to pull off two consecutive loops before deciding to do an upside down pass. For whatever reason I attempted an inverted loop and suffered the ill effects of an elevator pushrod that was a little flimsy (and binding to boot) She did a magnificent 5 meter, 40kmh swan-dive straight into the grass. The sound of it hitting the ground rang out like a gunshot - CRACK!

I strolled over to survey the site - I'd busted the rudder, two wing-mounts and popped the bottom of the micro servo (damn, those stickers really do keep them together - usually.) Luckily, the crash was repaired with some carefull aplication of more CA, masking tape and a cross-grain piece inserted into the rudder.


Bouyed by the crash of the night before I set out again yesterday towards the larger portion of the park, where I would be free from people, trees, backyards and people for the 280x700 meter field some 15 minutes walk away. Unfortunately, I realized when I was half way there that I'd forgotten to wrap some masking tape around the battery to ensure it didn't slip free from the velcro strap. Not worried, I pressed on.

When I finally got to the field, I was dismayed to learn that there was really quite a wind blowing - some 20kmh (12mph). Though I reasoned that it was probably only 3 times as bad as the wind the night before and that the instructions listed the flying weight of the plane as 4.5 - 5.5 oz, while mine was a hefty 7oz - meaning it should have a better ability to cut through the wind.

I set 2/3 throttle and gave her a gentle toss - again, same problem as the day before. Too frugal with elevator input. Dammit!
So trying again, I set 3/4 throttle and pitched her up at a steeper angle. Again there was an exciting moment or two while I got my bearings and brought the plane under control. I managed to hover in one spot for a moment before turning around and zipping down the 700 meter corridor in front of me.

The next thing to go through my mind was "Hmm, oh look - something's just fallen off. I wonder what it was - meh, it's probably just a wheel or something. Actually, it couldn't be - there's still two wheels on the plane. Hey, ee, oi, aaaahrgh! What's happening? That's not where I want to go. Ooh, oh crap she's coming down - dammit that's at least 8 meters. Better cut the throttle if I want to try to keep that prop. CRUNCH!



Since my TX has got, you guessed it - $2 worth of el-cheapo batteries in it I like to turn it off where possible. Arriving on the scene, I noticed something was funny or a bit off, though I couldn't put a finger on it. It then dawned on me that the ESC should be making the motor beep since it's still connected but there is no radio signal.

About then what had happened hit me like a ton of LiPo bricks. That ruddy battery that I'd neglected to secure had dropped out. CRAP! Now I really will have to find whatever came off. Gee, I feel like a real duffer for a couple of reasons right now.
(a) The obvious, the unsecured battery
(b) The fact that I never realized that I had absolutely no control over the model from that instant I dropped the battery. I truly thought it was responding to inputs for another 10 meters or so.


I was still very lucky - I just popped the bottom of the aileron servo again (radio is mounted on the fuse), dinged and punctured one of the wing tips and again broke the pair of wing-mounts. Disappointed with the lack of strength in my (balsa) plywood mounts that were glued to the stick, I set about cutting 4 U shaped pieces from (normal) plywood. By screwing them together in pairs, with one facing up and the other facing down I could have removable wing mounts that didn't need to be slid onto the fuse-stick from one end, while also allowing me to use the remaining length of the long screws to use as pegs for the rubber bands that would now hold the wing on.

So far my experience with this plane has been nothing but positive - I've never flown anything that wasn't on a computer or tv screen before, so to have made it from scratch (albeit with someone else's design) including the plan and fly it twice in fairly stiff wind, crash it twice really hard and spend $0 fixing it has been exhilarating .

Simon,

I am impressed! (Who wouldn't be?) You are truly a scratch builder, even making your own paint! If there are votes in this contest, you got mine!

BTW, I wandered over here too, by Chellie's direction, otherwise I hang around the Capricorn site. Might be worth while for you to see that, it is a Depron foam plane that is also very economical, and easy to repair. I have made an electronic copy of it and plugged it into FMS, a flight simulator that is free. So you can fly it on the PC before you do it for real. It's all there waiting for you.

Thanks DBacon. I know it thrilled and impressed me, but you know what they say about small minds... Didn't really know if it would even raise an iota of interest so I'm really glad you like it.

Yes, I've heard of FMS, though it refuses to run for me both under Win7 64bit and in an emulator running windows XP. Think I need to get some more (really old) DirectX DLL files to make it work. The thing I find amusing is that I extended the trial period of motocalc indefinitely in about 10 mins this afternoon though cannot get FMS to work for the life of me (and I've tried for hours) Ironic huh?.


Thanks for the Capricorn site tip, I'll have to go and check it out. there's a lovely old bluestone quarry nearby with a 200 x 50 meter lake in the the middle. I've fantasized about flying circles around the crater, and to be able to land on the water would just be the icing on the cake... Cheers!
