Flaperons - thoughts please

[Richard Cohen]

Hi all. i am quite new to the LMA and starting to get into larger models. My current models are not massive by any standards (around 80-90inches) but its a start I have a concern with one of my heavier models, a Cessna O2. I fly from a tarmac runway at Wroughton and the cessna rolls on and on after landing. It does not have flaps and retro fitting brakes is not feasible so i was looking at dialling in some flaperons to see if i can make slower approaches.
The wings have almost no sweep and almost square tips but i am still concerned whether flaperons might increase chance of tip stall. If any one has experience with whether this is a good idea or not it would be appreciated

Not got experience of that aircraft but on heavier warbirds without flaps I have used the flaperon function. Do NOT wind down outer edge ailerons . I Used it to raise the ailerons, this imparts washout preventing the chance of a tip stall. The overall effect on a wing is to reduce lift so in reality it increases speed and sink rate, not slower but safer to land.

The side effect is that without the fear of a sudden stall you actually have confidence to bring the model in slower making the landing roll shorter.
