I am new to helis and starting off with the blade cp, I have had a few minor crashes with forward flight but nothing to bad.have a problem getting the blades to track perfect like it used to. I replaced the main rotor shaft,blades and checked the spindle and tried it again tonight, seems alot better....but still cant get them perfect, seems like I have one pitch control link screwed in a bit more than the other to get it as close to track as I can.Is it possible I have the pitches of both blades off and making it hard to track? I dont have a pitch gauge so not sure if I screwed it all up messing with pitch control links trying to track it.any advice on what else to check for trackin problems and if I messed up anything?Thanks

Sounds like you need to invest in a pitch guage and see where you are with everything.. without a base line it's hard to tell what your doing...

yes I will, everytime I see one on sale they are out of stock,,but I know I need one.Would that cause the tracking to be off?

If you have adjusted the pitch links on the heli to fix the tracking and forgot where your settings were originally then yes. That will throw the tracking off, It also changes the pitch in each blade seperately. so you might be loading the motor and making it run hotter than it should with to much pitch...
It's a fine line between running great and having a crappy flying bird...The more precise your tuning of the heli is the better it is going to handle....

I argree with slider. I think its more important especially if you are just starting out to set your machine up as best as you can if not perfect. It takes patience. You can get someone to set it up for you but eventually you will need to learn setup on your own. If you dont have a pitch gauge you can use a level on top of the flybar to eyeball the pitch of the blades relative to eachother. and adjust the links connected to the blade grips. I find my CP2 flies beter with a higher head speed and less pitch. My Heli doesnt even get off the ground until about 70% throttle. Since Ive been flying it this way, the flight times seem to have doubled, and the motor stays cooler. good luck.

Twinring, That is the key to these cps get the headspeed as high as you can before adding pitch... It makes them more stable, and keeps the motors cool....
Reb32 I just thought of something to check, pull the blades off and see it they are both flat,no twist, and when held together at the blade grips they are parallel, I got a set that one blade had a big curve in it and I couldn't get the tracking right either....I trashed the one blade and grabbed another set off my wall of shame ( my wife calls my spare parts wall that)

Slider46,
yeah I just found this out about a week ago. Im so excited about flying it now. for about 2 months the heli sat on the shelf because I robbed the servos to put them into another heli. I was thinking about selling the CP2 so I put new parts in and set it up and while I was flying it I realized how great it was and changed my mind about the sell. It never flew like this from the factory. Setup is so important...

Also take a look at http://www.bladecprepair.com you will
find some helpful information on tracing and balancing
blades. Lots of other helpful stuff too. Like the other
post's stated set up is everything!

I will try that with the blades. I dont want it set up by someone else, I really enjoy working on it as much as flying it.I will slowly figure it all out. I replaced mainshaft and drive gear,center hub, spindle, and blades...still little vibration!! I have a black strip on one blade and it seems to ride in the center of the 3 blade apperance I am getting while trying to track...ha ha oh well it still flies but it bothers me now in the back of my head.
