RE: TWIST
I had three ounces on the nose of my twist with the .46 AX on it, but that was just to move the CG back twoards the front of the range for it's first flights. I"ve since put a Saito .56 on it, and while not grossly overpowered, it will hover and has plenty of vertical. The weight fell off sometime after I put the Saito on, and it flies fine... CG is still in the range but towards the rear. I also have the battery pack (1100 mAh Nicad) stuck on top of teh fuel tank as far fwd. as I could get it. Don't know why you would need lead unless with very light engine.....
