Sam,

I just finished framing a standard Bobcat for Bill Brundle. He had a RAM 500 for it, but has decided t switch it over and use a P-80. There is enough room for the header tank in the fuselage, so that won't be a problem. That would be your only set back and it isn't a problem.

The only differences between the standard and XL is the XL has a deeper fuselage in the belly, and the booms are about 1 - 2 inches longer, not sure of the exact length, and the fuselage on hte XL is a bit longer, somewhere around 1/2" or so.

Sholdn't be a problem at all.
