GY601 setup... help!

[warboysastro]

Sorted! The Manager kindly popped round this evening and got it fixed. Essentially a radio set-up issue on the gyro screen in terms of inhibiting the mix for the idle-ups rather than allowing it, plus setting the end points for channel 5 for gyro gain in both modes/sides of the switch, then bringing the rudder channel end points back up to 100%.

Have moved the servo horn hole inwards one, so all I need to do now is do some test hovers in normal mode to find the tail blade hover pitch setting, tighten it all up, then the job's a good un.

Thanks again to The Manager I owe you one.

Once I shift my cold I'll be out there getting it dialled in.

Cheers - Rob

No problem.

I'm not fully up-to-speed with Futaba radios, but your Tx clearly has a very similar gyro function to my JR 9xii which allows you to set different gyro gain values in all the different flight modes. However, in order to make this work, you have to plug your gain wire from the gyro into channel 7 (on the JR setup) rather than channel 5. But, the gyro you have is so good, that there's little point in having different gain settings, so the asnwer was to inhibit the gyro function on the Tx, and run the gyro in the traditional way off of channel 5.

Also, you have a 6 channel receiver installed, so you don't even have a channel 7!!!!

I had a nagging thought while I was driving home Rob. You've got a PPM receiver in an electric heli. I'm not sure if that's wise in your newest, favouritest heli, but it is of course open to debate. Any RF interference glitches (which are a common known problem in electric flight) will show up big time with that setup. I appreciate that you're waiting for the 2.4GHz module and receivers for your radio, but for peace of mind in the mean time, I think I'd be happier with a PCM receiver, but that's just my thoughts.

I have a PCM rx in my turbine jet at the moment which is going nowhere, so I could do a transplant...

Mind you, I have a cheapy lightweight ppm rx in my little electric heli and have never had glitches; mind you - the motor runs at less current and less Voltage.

Any other thoughts from anyone else on this probably very valid point The Manager has identified?

It would only take one PPM glitch to total the heli in idle-up close to the ground. But of course the same could be said of it going into PCM fail-safe at a great height.
