Any suggestions for foam thickness if I'm using compressed foam instead of EPP?
I did use blue FFF from home depot.
I still dont have my tx so cannot test but plane without electronic is 114g and look tough enough

Motor/ESC choices on the shelf as candidates for one or more of these planes, for indoor use or training children on the buddy box. 9mm EPP build.

1- Suppo 2208/8 2600kv with a 30A esc
2- No-name B2212/13 1000Kv with a 20A ESC,
3- No-name 2208-14 1450kv with the 18A ESC,
4- Blue wonder 1700kv with a 10A ESC (might be a 12A).

Which motors preferred and what order? Prop selections?

How thick is the blue foam used?

The blue FFF is 5 or 6mm.

Just found out that the compressed foam I have locally is very similar to depron. I've heard that Depron foam is more rigid compared to EPP, and maybe a thinner foam would do the job? In which case, would 6mm depron foam work for building the EzFly?

Thanks for all the help so far.

Check out page1 or so. I recall some folks building with depron or fff. But, yes, depron and fff being more rigid, you will not need as thick a foam. Still might want to reinforce with carbon fiber or wooden dowels, esp leading edge and at the step and around the prop slot.

Oh right, searching this thread for "depron" yielded all the answers I needed. As quoted by motorhead himself, 6mm depron is similar in weight to 9mm EPP. Although I recall someone telling me that EPP is heavier. Oh well, doesn't matter, I'll stick with 6mm compressed foam or depron or whatever they call it.

I've been happy wth a Blue wonder 1500kv, with a 10A ESC, so I might start with #4.

6x4 prop, I think that's the largest that fits into the slot as I've got it built.

I would use #4. As for prop you can probably run what ever you have been running on that motor as long as it is 8" or smaller. It depends on what battery you will be using.

All 4 motors are still in packaging, the first one will likely end up in a prop in slot F22, the BW will have it's choice of homes (and I've got a ton of orange 7x6 props for it) and the middle two were impulse buys and now I debate what sort of home to build for them.

Batteries I have a number of 3s 450s, two 2s 800s, then it goes up to the 3s 1300s, 1800s, 2200s.

Kind of excited I should have foam on the porch today or tomorrow, hot wire same time frame.

WInds finally let off to 5-10mph, so I gave my EZFly a go.


The guy wires worked quite well. Much more controllable and much better flying. I might install two short ones from the top of the vert stab to the horiz stabs. I already have the bbl swivel installed.

I will have to grind some of my stick mount away, though, to get some up-aft angle on the motor. At full throttle, it can do a loop with the elevator trimmed level. Kind like some of those pusher motor gliders:
