I also thought the glider was very heavy. However it appears to be factory glassed with very little user construction. The wing is marked Aerofly. I have a 10 and a 15 engine but the engine goes behind the CG (rear pylon), which means more lead in the front.

Maybe in the next few days I can catch the wind coming up the chute at 10 to 12 MPH and get it to glide a few hundred feet. After seeing a few glides the changes might become clear. Sorry but not much is known about gliders at my end.

Thanks for the information.
