I have to dissagree with spaceman spiff ..i love the 5 point or more pitch and throttle curve .. It makes the differece to me of driving a volkswagon bug to driving a caddie .. It is infintly more verasatle to have the more point puitch and throttle curves . I learned on a Helis with a JR 652 and a Futaba T6xas .. I was continually messing with the curves depending on the conditions and it was a nightmare to do that .. Here we have lots of wind and rain so it was a must .. I decided to get a Airtronics 6000super one time and then I put it in my heli and a couple of planks .. What a difference .. The heli was a new machine and was much easier to fly .. The main differece I noticed right off was in landing .. Once I had the pitch curve set with the 5 points .. There was no more bouncy landings right off .. I couldnt hardly believe it .. then I noticed the same in the air .. My heli seemed to fly much smoother .. I am not trying to sell you a Airtronics or anything ,but IMHO, I will never go back to mechanical radios again .. The digital is worth every penny and the digital trim is something I would have died for 30 yrs ago when I first started flying ...
