That's encouraging news. imho the Arplast prop blades are very good, Not
too stiff so they don't rattle like Warps do and plenty of area near the
root to help cooling at low speeds.
I have always wondered about residual vibration, you can never tell if
it is due to some criterion that cannot be balanced out. Good to have
cinfirmation that it can!

good result - I thought for a 912S, absolutely outstanding. The carbs had
recently been balanced by Adrian at Shobdon and they must be spot on.
