Hello I an building an Ultra Stick 60 with aelierons and flaps.

I am basically a sport flyer.

I am looking for suggestions for an engine. I was thinking MDS 78 but I am un sure if this will be enough power.

I do not care if the engine is two or four stroke as I have both.

I want to make sure I have enough power to really enjoy this airplane.

All suggestions and why will be very helpfull.

Thank you

Brian
