I'm using 2.4mm plywood as recommended but funny it's too thin and fragile as well. i broke it easily while trying to bend it. Will see how it goes after some flight. the build is half done now

Finished my A-10 with a few mods. No 3D printed parts and wanted to use a shorter power pod and keep them swappable.
Ducts use the score cut / gorilla glue technique that @DamoRC uses. I then built a simple foldover support with two popsicle sticks to attach to the fuse. The sticks pierce a few layers of foam and are glued in and seem strong enough.
My shorter power pods.
Enlarged the nacelles and simplified them so that everything can slide in and out. Also added landing gear with a rubber band support like in the kraken build video. Hopefully they hold up.
Using two C pack motors producing 4000g+ of thrust and the plane weighs about 1550g with a 3s 2700 battery. I think that should be enough.

10 x 4.5 currently.
Finally finished! I screwed up my ducts with my last sheet of WR foam, so gonna need a paint job now
Also didn't reprint the duct mounts cause my printer was busy with other projects, so used my library's laser cutter and some 1/8" ply. Balances nice with two 2200 3s batteries, so should have nice long flights.
Running two turnigy 2830s 1100kv with 10x4.7 props.

That was some great flying jpot! Also, nice video. How does the A-10 handle in a small space?

Amazingly it flys like a trainer!

I bought the kit and used a power pack C twin (GT2215/09 motors) and a 2200mah 3S battery for my maiden. It seemed really under powered and I had to fly at 100% throttle. I swapped in a 4500mah 4s battery and it flew great! I'm new to building electric airplanes though and I'm concerned running this setup on 4s may be overcooking the motors. I've ordered a watt meter to see how much power I'm pulling with the 4s battery.
For those of you that have flown your a-10 on a 3s lipo... what % of throttle were you using? Have any of you tried a 4s lipo?
I'm wondering what would happen if I used a 4s lipo with a 9x6 prop rather than a 10x4.7. I'll have to do some static testing once my watt meter arrives...
I've attached a few photos of my A10, I painted the rears of the engines with red/orange paint which made them look pretty cool when flying around. I did catch a lot of crap from the purists at my RC club for not doing EDFs, but I much prefer the prop setup myself.

The testing I did had a c pack motor maxed out with a 9x4.5 prop on 4s. That is the setup I use on the seaduck, great power. I use a leapord power 4s 3300 50c pack. Give 6 to 10min flight times. A 9x6 ran too much wattage and the motor got cooking quickly. The 10x4.5 had the same issue. If you are using the new ft motors tho, it might be able to handle it.

@nerdmanpap - yeah I was flying 100% throttle all the time in C pack equivalent Turnigy 2836/8 1100kv motors. I played with the timing on my escs and went to a 10x4.5 prop - no good. I just went and pulled the trigger on two of the new radial motors!

I imagine a bird this big wouldn't really mind the extra weight.

All that would do is add wieght and potentially flight time.
Going from 3s to 4s may or may not make a difference if you consider you have to prop down. I went to 4s on the seaduck because I liked the extra prop clearance of a 9" prop vs 10". I lost some static thrust, but gained some speed.

I was looking for flight time.
I initially had my legacy on a single battery (twin C motors) and she didn’t fly for more than five minutes.... at Flite Fest last year I didn’t make it back to the runway and her red tail was prominently displayed sticking out of the beans for all to see!
