The fact that it stalled indicates that there is sufficient elevator authority, and the balance is fine. You simply exceeded the wings stall angle. Doing this as the mainwheels touch is good, doing it a couple of feet high will make for untidyness. Perhaps you need to do lots of 'touch and goes' to refine the landing process with this model, rather trying to disguise a lack of practise with electronic and aerodynamic tweaking. Take the thing out, and do some concentrated 'flying with purpose' practising those things you do not do well, and always do 6 or more 'touch and go' landings, being really honest with youself and only stopping when you know that you have got it right. Throttle for glide slope control, elevator for speed control. It is unlikely that the tailplane/elevator stopped working, with prop slipstream over the tail there will always be some lift generated by the tail. If the model will stall and spin the tail is working and is keeping the wing stalled, the balance is fine.
