thanks a lot for your kind advice! I was completely unfamiliar with the concept of “breaking in the downlines”. Could this be achieved with the old 2 stroke by using a larger propeller?
my only concern with the YS is the high cost of the engine and that it does not fly with FAI fuel. I live outside the US, where it is impossible to buy nitro. Hence my inclination for a DLE or using the Rossi that I already possess.
