After flying heavy "metal" for a bit, I have been knocking around a Kaos arf and having a ball. Puchased a Venus 40 with a OS 55AX doing the work. Way cool whats up with that Knife edge . Now the question. Ordered a Venus II have no spare engines around cept' a OS FS 120FS thats in a P51 down for wing parts. HOWEVER, I do have a OS 2.0 FS from a Giant Super Sportster I sold on the shelf.

With good throttle management, you don't think I could "shoehorn" that big 4 stroke in there Dimension wise its real close. and I read a few posts of 1.80 four strokes in some Venus II's.

Besides excess fuel consumption, added wear on the airframe and scaring the hell out of my clubs safety officer. Is this a bad idea? or should I just pull the 1.20FS out of the P51 and go fly?

Best regards
