Hi everyone,

I'm looking for anyone with draganflyer III/IV experience (no speculations on this one please ) to fix something that must be a minor issue, yet being very annoying.


I'm a lucky owner of a DraganFlyer IV on which I am still learning to fly since a couple of weeks, and now I'm tired of something that isn't supposed to be normal on a machine that has gyros; I always need to compensate for the "heading" drifts, it either goes clockwise or counterclockwise, and even if I manage to compensate on the remote, it's still not "lockable" like an helicopter does. The pitch and bank gyros seems okay though, only the heading acts like this.

I don't know if it's normal behaviour and adding an extra controlling challenge on the device, but by looking at the example videos or other people's comment on flying it, it doesn't seem to be normal behaviour. there are potentiometers on the PCB, once is obviously to lock the PLL with the radio control, the other 2 I don't know but if they would be to set gyro gain, I guess there would be 3 of them (one for each gyro) so I don't want to mess with them before having any confirmation on what they do or how to calibrate the device better.

If anyone has experience or heard something about it, would be nice to pass along.

As for what this machine does, seeing it in the air; nothing beats it, yet
