Hi,
I Know this is a bit late for you but i would suggest you a Bossanova with that size of engine it whould be perfect.

I have a Jen 56 on my Bossanova very power full in 3D manuvers and never gave problems but the OS are the same type of engine so it will work fine on it.

Here is my video of prop hanging my Bossanova=
