The wisdom applied to those forums is mostly based on 3D type stuff. So it it may not apply to what you're trying to do with this helicopter. The ones that really got it down as far as tuning for stability and low headspeed is the scale guys. There's a fellow in our club that has a Trex 700-based Augusta A109 with a Wren 44i turbine it spinning a five blade rotor. And he also has a Bell 220 on a Trex 700 frame with a 44i in it. I just stand and stare with awe when he flies those things because they are so realistic right down the amount of rotor slap he has it tuned for, and the engine sound from startup to landing and shutdown. They are absolutely the closest it gets to the real thing.
But he has spent countless hours tuning and balancing and tweaking his radio because he flies them with no gyros at all. It is very impressive to watch him spool up that A109, taxi it out onto the runway, then lift off and pull the gear up, complete with the heat waves rolling off the tailpipes and the whine from the 44i turboshaft as he transitions into forward flight.
This is the guy that was my RC helicopter instructor when I got my 700 nitro. He's been flying RC helicopters for 36 years, he watches the 3D guys doing their stuff and he says what I think should be a famous quote in RC - "I've spent 30 years trying to get my helicopters to NOT do that".
So there's your two extremes in methodology and thinking.
