RE: 18MZ Telemetry log

Thank you. So what is actually a good range check? When reading the manual I cannot find a value of expected range. I know how to perform the range check, just dont know what distance to expect.

18MZ Telemetry log

Do the 18MZ allow telemetry data to be saved on file, or is it only capable of displaying data on the screen?

RE: Sebart's new pattern ship MYTHOS

RE: Sebart's new pattern ship MYTHOS

Rendegade, the 2m version comes like that. I believe you are confusing it with the 125 version (with clear canopy).

I’m considering purchasing a 18MZ. I think it’s an appealing transmitter, but what so far has kept me from doing the purchase is futabas limited range of receivers. For some applications I would...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

Brenner this effect is typical for high pitch props and comes from the blade partially stalling. Power goes down since less air is accelerated through the prop, however the power that still is...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

If you want to measure RPM I suppose the easiest way is to use an eagletree logger with dual rpm sensors. Log the motor rpm using the brushless motor rpm sensor and then the rear prop rpm using the...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes

I do not have any practical experience with a contra in F3A, but theoretically, yes the CG should be more forward with a contra setup. A propeller in front of CG is always destabilizing. The lower...

RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
