Hi all,  first off i've been reading through all these forums for several months, and i've found everyone to be quite helpfull and full of insight, so thanks for that.  My build so far is quite…Continue

"I suspect that you are getting the "wobbles" in the yaw axis prior to lift off is that as you increase rotor speed you get a yaw component and the controller is trying to control it, not getting any movement from the heli because it is on…"

Nitro Heli PID tuning (sorry no video)

It worked!! , sort of.  After several iterations of isolation designs, plus replacing just about every bearing on the heli including a set of ceramic bearings in the engine itself.  My heli flew over the weekend.  It was very brief and not without issues. However, at this point I'm very confidant that it will work. So I've attached a couple of pics showing my isolation, which is pretty much a fusion of what the multi guys are doing and Manfred's earplugs. …See More

"What works really well is to have your transmitter in heli-mode but turn off the CCPM.  IIRC this is called H1 on a Futaba.  that will allow you to have a single channel for each servo, which is what the APM is looking for, but still have…"

Hey I think that would be great.  I am currently working on building a Quad but I should have my Raptor back up shortly.  I am going to put a new frame and bearings in to back sure the vibes are down.  I am just really terrified of any future flights without a solid platform.  That incident was only a few feet away from me.
