Question
Epp & Depron foam, also Carbon fiber

Hi, I'm big into scratch building foamy's, thinking about starting production on one I've designed and had multiple requests to build, and I was wondering where I could get 3mm & 6mm Epp/Depron cheap. but still of the quality for an indoor 3D plane. I'm looking for the medium to large-size sheets.

Also, if anybody knows where I can get carbon fiber cheap, that would be much appreciated.

Thanks, JonathanZ

www.rcfoam.com sells depron, epp, and cf in just about any size. Really good folks to deal with,too.

There is a sticky post with foam sources. My preference is RC-Foam. Nice folks who often stick another sheet in free.

You're faster off the mark than I am. :-)

Sorry about the late reply.
Here's some pic's of my design. This is version 2 of the plane, V1 was an outdoor plane made with fan fold foam.
I still need to do some modifications, I'm guessing V3 or V4 before I start selling kits.

Thanks for the info, JonathanZ

Maybe because you are a good pilot or maybe because you are just lucky, but
you have a serious design problem. You have a structurally weak area where you have the servo mounted. I would suggest running a carbon rod along the bottom of the fuse in this area or connecting the wing supports above this area (which you now have mounted just aft of this point). I know from whence I speak, I have at least 40 little buggers like that hanging in my garage. Maybe the support rods above this area (on the top section) help but I think it is still a risky design. One good, hard, landing and the nose will break off. Just my opinion but I have many broken planes to prove my theory! Good luck

Thanks, the next version will have the servo in a different spot due to control throw problems anyway, but might put some carbon there just for good measure.
