Watch out for any increase towards tip stalling with flaperons. Especially with such a strongly tapered wing and what appears to be constant width strip ailerons.

With strip ailerons the increase in the camber and locak angle of incidence caused by drooping the flaperons will result in a washed in wing at the tips compared to the root. Yes, you're getting more lift to work with but if you slow the model down to really use the extra lift you could easily find that the model is more prone to tip stalling.

As per usual with such things do all the practicing the classic 3.5 mistakes high to get a feel for it.

It was a great landing at the end but it's hard to say if it was faster than no flaperons or not without being there or seeing some no flap landings to compare.
