That's what I did and it was awesome! I was going to have @SquirrelTail fly it at huckfest but then we kinda forgot haha.Top up the motor and I promise you that heavy won’t matter.

I just had an idea that might do XA 🤔 if I can get the airframe to last a few flights without separating I think itll do it!rip xa challenge

Got the first flight in, and it’s looking promising! The plane is an MX2, rocking the ft monster radial on 6s with a 60” wingspan.
Currently she flies very scale, so I’ll be bumping up my throws for 3D/XA. I’m having trouble with landing gear strength and build simplicity. This version can never be released because most parts are not exactly repeatable.
Honestly, I don’t really think 60” is the best size for a diy xa airplane. I have some ideas for smaller 48” series airplanes, or even a spin on the timber x.
Any thoughts appreciated.

48in And a 2418 on 4s would be the most reasonable. maybe 52 inch wing span might be a litte better because of the slightly bigger size. Im not ”great” 3d pilot so my input is purely theroretical .

I agree. I think the smallest I can reasonably go is 48”. Check out any extreme flight planes of the same size, and they fly great. Smaller is better when building with foamboard. A 2814 motor would be perfect on 4s with a 12x6 prop. Just need to find some fast but economical servos.

These emax 14.8g digital metal gear servos are only $12.50 a pop, with all 5 star reviews, some claiming to run them in 48" size 3d planes. They are very fast for running on 5v. Looks like a good option to me. LINK
The TMotor AS 2814 900kv is the most reasonable option coming in at $34. (LINK)
Finally the TMotor AT40a esc should be perfect at $16. The 5v 3a bec can support our 4 servos. (LINK)
Match with a 4s 2200mah battery and a 12x6 prop. Might as well throw in some tmotor 12x6 props for $4 a piece.
For example:
4 Servos - $50
Motor - $34
ESC - $16
3 Props - $12
Shipping- $15 ish
Roughly $130 plus whatever battery you choose or already have. Not bad at all for a 3d plane of this size.
Oh and all the work hours that goes into designing/building.

Thanks for the link for the servos I have been looking at an ef 48in and have everything but servos lol hitecs were a little pricey but I didn’t want to skip out on a nice plane. I will for sure be building a foamie of comparable size before putting them on anything “nice”.

Here’s a flight video for the 60”.

After increasing the throws and moving the CG further aft, it actually flies incredibly well. If I can simplify the build, it is viable to be published.

I do believe that the gauntlet has been tossed for best flying piece of foamboard!

DUDE WHAT?!??!?!?! Is that even possible with foamboard? I need to get in on whatever build techniques ur using.

Lightweight but strong! Also looks significantly better by having smooth airfoils on wings and tail.

This will definitely go to the top of my build list when you publish!!!
