Which ENGINE???
Hey There,
I just bought a P-51 Mustang...and I want to put a 4-Stroke .91 Engine in it. Towerhobbies has an O.S. FS-91 II Surpass and a Magnum XL-91RFS...The only difference I find is the $80....Is there any other major Difference...or does it really cost $80 to have the name OS put on it.
