I had one, and I have a friend who gave me parts for 3 of the low wing Colt Trainers.

here is what I can tell you:

A .46 is not alot of power for that plane, it will be a bit sluggish and need a long take off roll, but for a trainer slow is not a bad thing.

The plane can take one heck of a pounding, I saw my buddy nose dive his at full throttle into the ground, and he had it up the next weekend, you cannot do that with Balsa.

If you want to fly floats on it, you will need a .60 for sure to get any reasonable performance.

It is not really building, but folding and gluing, still it will take some time. I have now built about 7 planes and can tell you that the fun I have is the building side of the hobby, Aircore does not come close to the pride of building a proper balsa plane from plans and a box of wood.

Enjoy it, you will have fun, the .46 should be OK
