There are a few planes that you cant take the wing off, the Tower Uproar 40 for one. I built the Tiger 60 this winter as well. I powered it with a Super Tigre G 90. I cant wait to see some grass come out from under all the darn snow up so I can take it up. You might want to consider the G 75 as well. Its right in the middle of the power range for the plane.
