Does anyone have a CPPro or Pro2 with a CNC Head?
Which one do you have and how do you like it?
The two I know of are:

1. E-flite's own upgrade head and swashplate
2. MicroHeli head assembly

I think there is another one by Hobbyzone, but I don't know if it's a knock-off of one of the above.

I have a CP Pro2. I like it, but there is a LOT of slop in the stock head.

Also, what are your favorite main blades?

Thanks for the help.
Jay

Well I bought the Horizon CNC head and swashplate. Got it installed (there are no instructions...), but I am so new at this hobby, I can't tell if I made things better or worse.. *LOL* It seems that the heli is much more responsive now, but that makes it hard to control for a noob like me, and the transmitter that comes with the Pro 2 isn't programmable, so I can't smooth it out. I also installed the symmetrical carbon fiber blades from Horizon. Those I like.
Good luck with your mod.

Best I can tell it is set up tight... little, if any, slop. Magazine review says no slop in the CNC swash.
I'm beginning to think it may be a bit of an overkill though... the whole CPP2 frame is flimsy enough that it sways a bit when servos are moving, especially in idle up mode. Probably more sway than any slop... *LOL*

micro heli head
I have the Micro Heli head. It is a beautiful work of art - that I took off my blade last night for the last time and tossed it in the scrap box. I've tried and tried to get it working well and just never really had much luck with it. It can be made to work well but it has so many quirks (that I won't go into here) that I'm done with it.

I also don't like the sloppy plastic head but you know what? IT WORKS and works great. That's my two cents.

Mitchilito- I may do as you have done with your CNC head... set it aside to look at every now and then. I don't think my CPP2 has flown as well since I installed mine (the Horizon brand), but dang it sure looks good! LOL Maybe it added just a hair too much weight... I don't know. I'm still in hover mode, and I increased the pitch at center stick 1-2 degrees so I can get off the ground a little sooner at a lower head speed, and I think it made the heli a tad more stable... does not bob up and down as much, best as I can tell.
Good luck with yours.

So I have also been having a nightmare with my e-flite cnc head. I have adjusted and checked and set and reset everything and tried everything I could think of to get the heli to fly as it did with the plastic head. Nothing worked, til now. I have a plastic "practice/crash" heli and then the metal/carbon "Sunday Best" heli. Comparing the two I realized the the ball links on the plastic mixers arms are offset to one another. Not so with the metal ones. I removed the ball link on the short side that runs to the flybar frame and reinstalled it to face outwards. Left the other facing in towards the main shaft. It was all nice and well behaved after that. I think with a blade track and some fine tuning of pitch this heli will fly as smooth and stable as my crash copter.

I suspect during manufacturing it was easier to place both ball links facing the same direction, when they should be opposing. I changed one and fired up to check the difference of movement of the two sides and the angles are quite different between the two setups. The opposing setup even looked like it worked better.

The other thing that had to be changed was the flybar, as the stainless flybar was bent. ??? No crashes so no explanation as to why. To revert to the stock flybar I had to remove the metal flybar seesaw(ELFH1179) and replace it with the stock plastic one(ELFH1146). The stock flybar would not fit through the bearings on the metal unit.
After this was done I noticed that the paddles were much more positively place, before it seemed as though they were not nearly tight enough to stay in place without glue.

Hope this helps some of you guys and maybe your $100+ heads aren't dust collectors, they look so nice on these heli's

7K,
This is some good info. I may get the Horizon cnc head eventually and now I'll know what to do.

Thanks!

Yeah, I noticed that about the stainless flybar also... it is thin and bends easily. It fits loosely into the paddle threads (I used a small piece of wooden matchstick in the threads to tighten them up... didn't want a permanent position).
I'll have to go back and take a look at the ball links as you suggested.
Thanks for the tip.

7kcabfun,

Could you post a photo or drawing of what change you made with the ball links on your metal head. I've read your discription a few times and being a dense beginner, don't understand what part needs to be changed.

Thanks, Jerry

CNC Head
So the first photo is of the metal bell mixer arm as it comes with the head. It is next to a plastic mixer arm for comparison. The second photo is of the metal part with the ball link turned the opposite way as it should be. This one little change made my outta control heli into a stable flyer.
