I had a Saito 90 twin in mine which flew it very scale. Had to use energy management to fly aerobatics and was fun.

Put a OS 160 twin in it and WOW! It flies great.

Lots of power, vertical, and it is a perfect home for the engine.

Best prop for it is a 17X6 APC but will pull out of hover with a 18X6 as well.

I have a friend that has a YS 120 in his. He is very happy with that combination.

You can always throttle back and use a low pitch prop for more thrust.
