Bigger engine in a Raptor 50

[agnar]

Anoyone having experience with a 70 (or even 90) engine in a Raptor 50.Is it possible to do,easy enough to fit?

I don't think many have done this. You'd need a new engine mount, clutch, clutch bell, main gear, pinion, longer tail boom to swing the bigger blades...Why not just buy the 90? I'm not criticizing, I just don't think it would be a good idea.
