RE: Ultrasport + Just starting
I cannot comment on the US+. But the US 60 with retracts I sure can. Mine is powered with an ASP 61. The gear is Springair 103HD's. The plane is awesome in the air. Just plain Phenominal. The bird is smooth as glass, very paternlike. i would absolutely encourage you to use retracts in this kit. Just be sure to reinforce the ribs the gear goes in. I used a lite ply doubler rib and made my own mount out of 1/4" plywood. Workes great.
