Hey Rocko

I mounted a TT46Pro sideways with a Pitts style muffler and it works fine. You may have to trim the cowling a little near the prop washer but if you measure correctly you might not. You will definately need a low profile servo for the ailerons as the wings are fairly thin. I think I used a HS-77? Anyway, 3 standard servos and one low profile servo. The plane is a ton of fun to fly and I built it completely stock right out of the box.

Good luck and have fun!
