Powered gliders are harder to learn on. The .049's don't run
well, and won't give a steady supply of power. When their screamin', the glider will climb like mad....and are hard to keep level.
And your lucky to get a couple minutes of flight time in.

Keep playing with the glider, until you can get a real trainer.

I always recommend the .60 size, because they fly better than the .40's, and are easier to see in the air. Look for something
with a 65 inch or bigger wing.

Is your motor mounted in the nose, or on a pod ? The nose mount is better. I've never seen a pod mount that worked very well.

Good luck....Dave.
