How great this forum is.
I have learnt something new, again.

One of my S9102's has been making the aileron bounce up and down, on the ground.
I thought it was because the ailerons were too heavy (they are VERY heavy on myAresti III, great lumps of wood).

I assumed that in the air, it would stay neutral, as I didn't really see/feel as if it was hunting.


A lesson learned.

Have just seen a special on JR8231, which will fit my budget.
Thanks for help.
