I still give the edge to EPP as it is much more durable than depron.

definitely more durable for the beginner to intermediate. The 6mm Depron is about the same weight as the 9mm EPP but the stiffness makes it a lot more crisp without the fragility of the 3mm Depron. it's all what you enjoy and want the plane to be for

FWIW, the Japanese team at the F3P worlds had models made from 3mm EPP.

They inlayed Carbon strips and used external bracing like you would in a Depron model. It could possibly make for a very durable plane.

One of my customers locally had me cut him a 3mm EPP framework and he used Tyvek tape to assemble it. Very impressive. At WRAM last year there was a 70g plane that was a CF framework with mylar over it and TechOne has something similar now

There were quite a few CF framed models with mylar covering, and a lot with Depron frames and mylar covering.

In fact in the top ten only 3 were milled Depron, the rest used Mylar covering

The lightest model was the French carbon framed one - it just floated through the sequence. It would have placed higher in the final but for some reason it just refused to do the anti-torque roll.
He had to cheat and do a slow climb to get it to turn. Cost him a lot of points.

They're far more manueverable than my YAKs are. Amazing considering how slow they're going.

I think that is amazing too. Slow, floaty and graceful at times, yet hyper maneuverable when demanded.

I'm at the WRAM show this weekend. I need to get the instructions done when I get back. I think the plane is in its final configuration now. More info as the week progresses

Ok, thanks. I can't make it to the WRAM show though. Will it be at the Weak Signals Show?

I have be collecting foam from work over the last year with plans to build up a new yak. It is black foam squares 10 x 14. I have experimented with foam tack glue and the foam is responding well to glue. The foam is very durable but more flexible than epp and I am considering using it to build a full fuse Yak or Extra.

Do you guys know of any full fuse Yak or Extra plans somewhere?
