When I had mine I had an OS46AX and it was more than enough. With a 60 you would probably not even have the ground clearance for the prop you would need and even if you did, you would probably have a hard time getting it to balance, takeoff would be a just a click or two above idle and flying at about 1/8th throttle and much more than that may cause the plane to flutter itself to pieces and this all depends if you can even shoehorn the thing into the mount.

Veritcal would be good enough for orbital work and would rival the lanuch speed of the space shuttle in scale. You would definitely need to strengthen the firewall by pinning it and throttle management would be an absolute must., Heck that's the recommended engine for the 60 size and it's plenty on that plane.

Now I am saying I do not recommend it but I got to tell you it would be wild to see
