As for other mods, well, the sky's the limit. I'm trying not to go nuts on this one like I did with my WM Super Stunt 60. So Iwill limit myself to the main gear mod and other prudent reinforcements.
Here's a look at the back of the firewall, with some tri-stock and the usually fiberglass complement.
I'll probably ditch the stock tail wheel - I don't like permanently mounted ones. I have a couple of Klett .60 size tailwheels that might do the trick.
I'm not gonna put the, IMHO cheesy, ABS wingtips on. The wingtips will be left squared off and covered over. Besides, 76" wing fits in my pickup bed better.
A 16 Oz. tank will fit no problem. The stock tank is a little small for a 1.20FS.
That's all I can think of. This is a well thought out and designed model and, as such, don't need much builder's embelishment to be an excellent flyer.
