As in your previous thread, I say no to flapperons and yes to split flaps; since you want to slow the plane and make it clear the trees next to the landing strip.

Deploying spoilers is like cuting the wings to the plane in midair; resulting in fast fall.

Deploying flaps is like adding extra wings and attaching a parachute to the plane in midair; resulting in slow approach.

I may be wrong, but anyhow, be careful today and give little deflection to the spoilerons at the beginning and increase the angle little by little in each flight.
I hope it works for you.

I wish I had a Strega!!![]
