By all means, go ahead and repair it ! Repairs like this are all a part of the learning process. From what I can see I might buy a replacement horz. stab, and do a leading edge repair on the right wing. If you did rebuild the right half of the horz. stab on the plane you should install a tail wire kit on it for strength. Better to cut the horz. stab out and scratch build a complete new one, or just buy a replacement from Tower. Have fun
