Default my plane is ballooning

<span style="font-family: Comic Sans MS">so i got around to taking the LT flying this weekend.she isballooning in flight when i go full throttle. i have an LT-25 with an O.S. .32 motor with a 10x6 prop. (can't everhave too much power)the CG is set per instruction. it never did thisalot before, but then i never really pushed the envelope with it. i normally fly around at about 1/2 throttle, but now when i push it to full, the plane wants to climb like crazy, and requires mucho down trim. other thresholds are great as far as not trying to bank or yaw when i push it up, just the climbing deal. i couldn't imagine the wing being twisted. it looks fine, anyway. the only time i noticed it was on takeoff, i never really had to input much elevator for her to get in the air. i guess just the normal amount. is this not normal? am i getting too much ground speed, thus inducing the ballooning on takeoff?and she tracks straight on the ground. aside from wing incedence and down thrust on the motor, is there much else to do? i'm looking for maybe a couple other known secrets to try as well, that maybe won't effect the flight when i am putting around at 1/2 stick. i don't want to need up trim.i want to get used to flying a little faster, before busting out the RV-4 again (spent a couple years in the hangar) or the SMP. it's not that it's hard to handle, but just annoying adjusting the trim to speed up or slow down. i even moved the fuel tank under the CG, so that wouldn't effect it when the level started getting low, with the servos in front. (that was done way before this ordeal though)</span>
