Also been looking at the Cricut, basically a poor man's plotter. There is some software out there that works around having to use their cartridges and works directly off of your PC.

I am going to start building one of these tonight. Been flying the shockflyer on clearview LOTS and love it. So here's what I have.

Stack of FFF (blue foam)
Suppomodel B2207/17 motor/ESC
HS65 for ailerons, HS55 for rudder and elevator
3S 1000mah lipos
Will have a spektrum rx

Since the motor and batteries are heavy, I was thinking the 36" WS should work? Will that give me enough "floatiness" AKA low wing loading? Or do I need a 42"?

I was thinking that since FFF is so much thinner and lighter than EPP, could I double up on the thickness to make it more sturdy? Use a 3M spray adhesive or something to stack 2 pieces together before cutting out the parts? Or is the weight addition not worth the strength addition? I'll probably crash lots because I haven't flown a plane in a while. I fly helicopters pretty regularily, and I only crash on the sim when I want to (IE start 3d'ing).

Thanks for any input,

36" would be a good place to start.

Anybody have any insight into the double thickness FFF? I cut out the template last night and Im ready to cut foam tonight. Just dont know if I should do double thick or stick to single.

A single layer should work. You could double up around the nose since this is the part that usually gets the most abuse.

Good luck, let us know how your FFF Yak works out.

Whats the difference? How does the EPP fly much different?

For one, EPP is much more forgiving (when the ground is considered). It might actually be lighter too.......not sure on that one.

Well yes I understand EPP will crash thousands of times better than FFF... blue foam shatters...exploads... whatever you want to call it. But FFF should be similar in the air isn't it?

EPP flies better because:
1) the thicker foam wing seems to allow slower flight speeds
2) less crash anxiety allows you to learn faster
3) less rigid airframe can be like adding expo, smooths things out.

Rigid foam flies better because:
1) Stiff airframe has crisper control and more precise handling
2) Stiff airframe will normally fly faster
3) Probably some others if I thought hard enough

Which one is "better overall" is a matter of what you want in a plane.

Id love one that I can nose in after a botched hammerhead???

I blew up my corsair that way... I think when I came screaming downwards, I pulled up too hard and the wings couldn't take the G's... then straight into the ground. Toast! That cost me .32 cents! But the time it takes to build is what sucks in a crash. Id rather split it between cost and time...

I figure I'll test out the FFF and see how it does and if I like the feel I'll go to EPP. Id rather have a smaller plane all around than what Im making (the 36" WS) but oh well. I dont think parking lot flying is an option really.

I have one layer of foam cut. I'll cut the other tonight, then glue them together double thick. The thickness of 2 pieces of FFF is exactly the thickness the templates show. That works out nice

Hey guys, I have an 11 year old Grandson I have gotten started flying on a HZ Super Cub and lately graduated into a Leadfeather EPPEdge 540. He currently has operating problems with both planes and I am unable to troubleshoot quickly by telephone from 600 miles away. He lives in the Gibsonia/ Mars area near Pittsburgh. Is there a good club or someone interested in mentoring a smart young pilot in that neck of the woods?
Thanks for any leads!

Mentoring an 11 year boy might open a whole can of worms. Jeez, in the UK parents arn't even allowed to shoot vids of their own kids sports days. Best make sure his parents are on board. Hey, perhaps they might be converted to RC foam heaven!

Parents on Board

Mom and Dad are on board and involved, just not able to get technical enuf to lead the charge without help from an experienced RCer.
Thanks for the comment!
