I wanted to sign up to answer a few things about the CNC blade grips and some of the "problems" people have or have had. I was pretty leary about doing the grips because of all of the stories I had heard as well. I also didn't find out about the E-Flite lower head and Micro Heli grip problem until I had them. I am referring to the stock linkages not being long enough from the E-Flite CNC swashplate to the Micro Heli lower grips. I did about every combo I could until I saw what the probalem actually seems to be. The stock plastic E-Flite swashplate at the top where the outer shaft comes through was flush and relatively flat. The CNC piece has a sleeve that seems to protrude about a 1/16th of an inch higher therefore causing the swashplate to come in contact with the lower head when trying to snap the linkages on and therefore binding it. If you tried to fly this way it would be VERY erratic and not worth the time spent trying to fly. Rather than having to buy the Micro Heli lower head, I pulled off the E-Flite lower head and used a grinder to remove that 1/16th of inch I mentioned. (Please make sure to file everything back SMOOTH after the grinder!) After that I had zero tolerance problems and everything went on well. I can hover the heli as still as I want and with almost zero "tail walk" and no erratic movement like some people complained of.

The only thing that seems to happen is that people are taking a heli that is not "tuned" properly when in stock form and the mods amplify that. I found and book marked a few guides that helped mine out TREMENDOUSLY in the flight characteristics. Then when I added the CNC parts, if anything, everything seemed to just "smooth out" a bit I would guess due to the tighter tolerances of the CNC parts. Another thing is the blade tightness with the grips. Unlike the CCP heli's, these grips need to be pretty snug and only allowing for slight movement in the blades with a decent amount of pressure on them. To make them straight, you can either eyeball them, Pull them straight out kind of like the CCP trick, or make them loose, spin them and then tighten them up after they get straight. I can dig up the links to the "tuning" guides if anyone is interested or I can try and throw together a consolidated version of it all too when I have a bit ore time to do so if anyone is interested.
