What is it doing to me it soars great.
This is all quite normal. Remember gliders are made to glide, and thermal gliders do it slowly. If you have your trim set for slow gliding speed speed and then apply power in level flight, the glider will nose up and want to climb. It can also loop on takeoff, or at least fall over on its back.
What you have to do is drop the nose as you add power and then once you get to your desired speed, re-trim. That is how airplanes fly.
Gliders are not optimal for powered flight. Those of us who use electric thermal-ling gliders use the motors only to gain altitude in lieu of the high-start. Once we get to altitude, we shut off the motor and look for lift.
Before I fly my Radian I do a couple of power off hand launches to make sure my trim hasn't changed since the last time I've flown it. From experience I know that the plane will glide to a perfect hands off landing when things are right. Then my custom is to hand launch without power and smoothly add power while holding the nose in climb attitude until I get to about 80%. When I hit my altitude I smoothly back off the throttle while lowering the nose to level flight.
In order to help things along I have dual, even triple rates set for rudder and elevator. I use the lowest rate and maximum expo during the launch and climb phase, high rates for thermal-ling, and a medium rate for landing.
It is also possible that you used a motor that has too much pep for the plane. In that case you might want to change it or use a lower pitch prop. You could also just leave it alone and use less power. But do consider the dual/triple rate approach.
PS I do not change my trim for takeoff. Don't see a point in doing that since the climb phase is less than a minute.
