Montague's comments are right on the money.

I would try slipping it in, but learning to slip is tricky and some planes don't do it as well as others.

If it were me, I would try spoilerons. As Monty said, they will not cause a stall, in fact, just the opposite.

I used to fly full-scale sailplanes and the trick to a perfect landing was to stay higher than you needed to be, and pull out your spoilers to regulate altitude.

The nice thing about spoilers is that your plane will sink like crazy without gaining airspeed - the problem is regulating it. They would need to be controlled by your Tx in such a way that you could turn them OFF before you pancaked into the ground.
