Next step, found some colored foam board at office depot. $4 a sheet. Haven't found any discussion on using colored foam board but tried it anyway. I think looks pretty good and avoids having to paint. Added simple FT decal and pleased with outcome. Practiced painting and waterproofing some small pieces but so far find that this 'alternative' board doesn't handle paint very well at all. Neither does it seem to handle glaze. But I can live with it as is so far.

Such a clean build - good job! Do you have a motor for it yet? Right now the 2206 FT radials are on sale for $13. I picked up a couple but haven't tested them yet.
hey thanks for input. and thanks for info on motor. I don't have motor or esc yet...so will follow up on that.

So got it done and ready to maiden. looks ok, but here is summary advice. Don't use the colored foam board! It turned out to be slightly thinner than the FT foam board and that resulted in some warping of control surfaces once electronics were installed. The foam board I used wasn't water proof so I sprayed light coat of clear coat on it. That turned out bad too. some of the paper just delaminated and once it dried the paper tightened up and did a little more warping of the whole model. Oh well, live and learn. I enjoyed my first scratch build. BUT will stick with the FT foam board moving forward. If this one flies I will be surprised. And if it lasts more than a few flights even more surprised. Good news is I have all of the internal stuff and less than $10 into the actual airframe.
