Hey Doug, I think that your plane will make it off in that distance as long as you keep her light, a good set of firm wheels will also shorten the take off roll, it makes a big difference! Also make sure that the nose is sitting high to help with rotation, will keep it from leaping off the ground. The plane is rather nose heavy at takeoff due to the fuel sitting on top of the nose gear, my A-4 had a CG shift of 7/8'' from a full tank to empty. A big thing to remember is to keep the speed up in the turns and don't pull hard or it will snap out and then you are in for a tumble to its death!
