Default Project: GWS A-10 Warthog EDF Brushless

I picked up GWS A-10 and I'm getting ready to build it up. I would like to use a couple of KMS inrunners that I already have with duckfans. Also thinking about glassing it with poly and 3/4oz. I've been following FiremanBills and Kosh's threads and can't wait to get started.
Looking for any advise/tips before I start. Thanks

Default Fan Blades

I noticed my fan setup has 6 blades but all the photos of the A10 show 3 blades. I'm wondering what would be better with a brushless setup. Anyone have any advice and why they change to 6 blades?

I've been doing more research on the A-10 and there's not to many nice things said about it other then it looks good. Most every review complained about no power and to fragil. I think I will take FBs idea and fill the nose with foam. I'm also leaning more towards glassing it with poly/3/4oz glass to keep it stronger.

No but I am really getting the urge! It is either going to be that or a BIG electric Yak or something like that. I like the multi engines an awful lot though...

Default 80" P 61?

Who makes the P 61 in that size ?

I like 2 or more also.

Advanced Scale Models sold through Hobby People.
http://www.hobbypeople.net/gallery/190105.asp Both planes have info on making them brushless . The C-130 takes 4- .25-.32 and the Widow needs 2 .60. I.m looking at the E-flite Power Outrunners to power one of these .

I have an A-10 that is about a year old. I' running the 55/300 fans with a Himaxx 2015-3600 and CC Phoenix 10 esc's. I use a single 3s 2100 prolite pack. I replaced the spar with a CF rod, I cut out a battery access hatch on the forward top fuse and run two CF rods down the sides to make up for any loss from the hatch. I glued the wing on.

Flies great

Reading all the threads on the GWS A-10 the best flying ones are the light ones. Unless you have big power glassing adds a bunch of weight that you don't want. The only reinforcing really needed is a CF rod / tube between the nacelles. I have one I'm starting on with the small 50 mm fans and Feigao motors Thunderbird 9 ESC's & 800 Mah 20C 3s. My first post. And I see a need for a
Scratch built foamies section.

JJP, Glueing the wing on, Hummmm. I 've thought about that on other planes, mainly due to my Fantom jet since it's wing is part of the fuse when it hits hard it just tumbles, and most planes are weakest where the saddles are so if access isn't a problem making a foam plane one-piece may work. JJP hows it working.

First off, Welcome to WattFler. I could not agree with you more on the lighter the better. The reason I'm glassing is for the long term. My glassed foamys last longer and my planes only end up weighing 2-3oz more then without so I choose to glass them and make them a little stronger. IMO they fly better in the wind due to less foam flex. In the past when one of my foamys came in contact with mother earth there would be hundreds of little pieces of foam blowing off in the wind making repairs impossible, where when there glassed there's alot less pieces to collect and much easier to repair (just my 2 cents) so for me the added weight is worth it in the long run.
I don't glass all my foamys, the Multiplex EPP foam is awesome and takes a real beating on my Twin Star II and Mini Mag. I'm finishing my GWs P-38 and on this Plane I only glassed the tail booms and the bottom of the main wing to keep it light and I alway's try to make up for the added weight by using the lightest gear I can .

Are you using fiberglass cloth or tissue paper ? I have read great things about the paper with water base poly. Lite & smooth.

I have not done the A-10. Yet. But on the GWS P38 I reenforced the movable vertical rudder where it is so weakened by the cutout. I cut 4 pieces of thin wood veneer, about 1" x 2.5" onto them and carefully glued and sanded them. A little Lite Spackel, and what a stiff rudder it became. I Sprayed the plane gloss black for a night interdiction role. Talk about a BAD color! Every defect jumps up to be seen.

Hey Ken, I tried the tissue paper a while back and my results had wringles in the paper and I tried for ever to work them out only to tear the paper , and when I finished it, it didn't seem any stronger so IMO it wasn't worth the weight gain for only being alittle stronger then bare foam. I've seen threads where guy's are having good results with paper but for me it was to hard to work with so I've been using 3/4oz cloth with Minwax Polycrylic.

Hey Cyclops, do you have a thread on your 38 or one your following. I noticed the P-38 has a weak tail after cutting the elevator off and I wraped 3/4oz glass around it and made it permanent to the tail booms to help get some of the weakness outta it.

Yep I might lay a layer of glass & poly on the belly of the A-10 But its just a shelf plane at the moment. I don't plan on using the landing gear so I'll save some weight there besides it looks funky. Its like those non jet guys that hang a prop on the back of a jet and still call it a jet.
Faux Jet Hehe. I was looking real hard at some 55MM fans and some 55 gram motors. 52$ for 2 motors & 2 fans + another 20$ for ESC's. Nah I'll put my Feigao's & GWS 50's in it for now. Thinking with my finger. I haven't tried the paper but ?

Default No Gear

Yeah bowtie I have to agree with you on the landing gear, I'm also going without it to save some weight . Glassing the belly when going without gear is a good idea and another thing is my glassed planes look alot better and is nicer to paint (hides all the little round foam beads making it smoother).
Last night I finished painting my P-38 and packed foam in the nose of the A-10 to help keep it togeather (thanks FB for the idea ). I think I may only glass the bottom of it like I did on the 38. As soon as I locate my camera I'll post my progress .

I haven't looked at the fuselage up close but I'm wondering about the packing the nose thing cause I'm told I'll have to move my little battery forward.

I guess twin guys go for the 38 and the new A-10 ?
I had to beef the vertical, as I have each one on a HS-55 with pull-pull. Same for the elevator. No airlerons. I just weighed it and it goes 22 oz. 1/2 painted and no batteries. NIMH only.

What does the A-10 start at, in foam pieces only weight?
I love to build.
What is the minumum and average, inrunner motor KV/fan MM, setup, if using GWS all the way?

Good thing I have a full basement with a unused train layout.
This is my build thread if it is ok that I hop back and forth on both planes. I will pay the dues by buying a A-10.

It should arrive in 3 days.

I unpacked my A-10 slope EDF 50. Wing 58 grams, Fuselage 46 grams, Rudders & stabilizer 18 grams, Nacelles 22 grams, = 144 grams all on at once 146 grams, plastic canopy 8 grams. I didn't weigh the parts kit. Hows that for service. Now after looking at it I'm thinking I might have to start the smoothing process & sand that puppy down. Drop a few grams.

I just got ONE!

I have two AC-DIYMOT-VL motors on 10turn w/ 55 ducts ready to go, fyi the AC-DIYMOT-VL motors are kit versions of the Hyperion P1913M-06-20 Motor it's only 21ea!! http://www.aircraft-world.com/shopexd.asp?id=2746

i'm going to glass the LE of the main wing and add carbon where i can

I'll be using two PH 10 w/ a TP2000 3cell pack, i have a scratch built "twin wing" that is running this setup very well


each fan draws ~8-9amps and runs @ about 19,000rpm on 11.1V
