First, I would seriously reconsider a .48 4-stroke in this Cub. I believe power will be marginal.

If you do install it, take the time to move the firewall back. Extending the nose may create balance and handling problems.

I have an old Sig 71" Cub that is powered by an OS .26 FS. I took care to build it light and the .26 provides enough power for scale-like flight. A .48 FS will no doubt provide enough power unless you build a very heavy Cub.
