I'm looking at making a powered sailplane with a ducted fan and would
need at minimum 75HP. I'd much prefer something closer to 120HP, but
I dont know what size and weight tradeoffs that would entail.

I'm no expert in this, but I'm curious: Why so much power????

Could be this motorglider is going to be a glider tow plane too.
