BTW, one thing that gliders have going for them, one HUGE asset, is that they can be test glided very safely.

Find a large flat area and throw the sucker!

OK, that's a simplification. But you will need a large area. Eventhough you're only going to be pushing the glider off from an extended arm, they can go a VERY long way. The idea is to hold the TX in one hand and the glider over your head. Jog a little to get the feel of the airplane. Jog directly into the wind. Hold the airplane level and try to find a handhold where it is balanced. Jog fast enough that you feel it go light.

When it goes light it will also show you any really bad out-of-trim's that are in the sucker. Don't start retrimming until you've seen the same thing again and again. Gusts can fool you. And if you're new to gliders you've probably not learned to read the ground wind all the time, nor what it's saying. (Full scale guys have no need to develop any of the RC glider guys tricks and feels and usually no idea they exist.)

Pay particular attention to the pitch reaction of the glider on these jogs. You really don't want the sucker to pitch up on release. And you don't want it nosing down hard. The bird will be at the lowspeed end of the envelope when you're jogging. It can actually be flying in your hand.

Kewl, ain't it??? so..............
