With all of the wrestling around to get the cowl details done I've managed to dent the foam canopy.
Should have bit the bullet and ordered some light balsa block.
I don't want to add a bunch of weight with FG, epoxy, bondo, etc...this plane is just a trial version I'll bet...there will probably be a 2nd version with some tweaks like a longer tail and more wingspan.

So, this one will get a down & dirty finish, then go fly it.
