OP that is a cool looking plane for sure. I guess that is the first time i saw the 90. Thanks for the pic. and the link. Look good.
The Flycat he is talking there is not a place even made for it to go. Seems like he might just have to guess at best. Sure looks
like some place would be set aside for the tank to mount. OP knows more about there inventory than I so maybe he can help you
out.
