RE: Best trainer plane for a Complete Beginner
I have flown the lightweight trainers and a Kadet, and I prefer the Kadet. The added weight makes all the difference in the world. I did learn to fly using a BNF UM T-28, and that poor little plane looks it too.
For the OP, go spend $100 on one of the UM planes, find a nice open field with no wind and enjoy. Just remember to keep your fingers away from the prop. If the plane survives more than a few flights, then go find a club, an instructor and a real trainer plane.
