Attention
According to the European distributor of Valach engines, it is not safe to fly the Valach vm210 without the update with the extra rear ball bearing. The crankshaft might break in flight at the rear crank pin.This extra bearing takes away a good part of the stress from the
rear crank pin.
How many of you Valach owners knew about this?
This is somthing the European distributor of Valach engines, have known about for several months.
The European distributor of Valach engines also demand i should pay for the shipping back to Germany to get the update done, is this normal ?
