I just bought the Hobbico digital volt meter MKIII and have taken all the guess work out of whether it is safe to fly or not.

RE: OS FS 40 surpass valve timing

Bax is correct.

This is a direct quote from the OS web sight.

Prop sizes

Is a 13-4 to little prop for a Magnum 61RFS?, all of the charts I have seen recommend a 13-5 6 or 7. I am looking for a good pulling prop and not interested in speed (excessive speed). The engine...

RE: Magnum 61RFS

After discovering the timing was off by one tooth from the factory I am now getting 9700 RPM after a few clicks rich. What a difference one tooth can make.

RE: 4 Stroke compression leak - disassembly no good
