LoneAL:

You say your spadstick is "spaztic" in the air but you didn't say what it's doing. If it seems uncontrolable in the air (either climbs or dives) no matter what you do to trim it check the CG of your spad and I'll bet you will find that it is tail heavy. My first spad did this exact thing....was a tad tail heavy which made it a real handful to fly. If it balances out ok then check to make sure the ailerons aren't drooping below the trailing edge of your spadstick wing.....they should be actually reflexed (tipped up a about a 1/4") and that sometimes will help out quite a bit as well.

Don't give up on the spad concept just because it's plastic and everyone says they fly like a brick. I've crashed my spads hard enough to turn a balsa plane into nothing more than a trashbag full of toothpicks with no damage other than maybe a busted prop or the need to straighten the landing gear.
