Mick, setting up at mid stick is all about getting equal throw on the blades. This is a once in a while operation and is normally done after changing something in the head. Tracking will need to be done more often as each blade you fit will track slightly differently. The trick is to use one grip and its associated blade as the 'master' and set the other to match it. If you don't use a master grip reference then you'll affect the mid stick position by adjusting both. Hope this helps.
Pete, always designate one of the blades as the 'master' and adjust the other to match. I mark my master with a little piece of tape so I can see it in flight. The blades should read the same pitch exactly on the bench but may need a small adjustment when flown as the smallest difference in the shape of the blade affect the lift it generates and how high it rides. Get the blades exactly the same pitch on the bench (watch to make sure the flybar is level) and then test fly. Hope this helps.
Another one could be that on blades rotating the bearings start to tighten (wrongly assembled). One tightens more than the other. Then you get variable blade tracking along pitching up and down. A hard one to find if you have not seen this before.
Thanks for the comment, I use Align 'O' Rings (Part number HS1186T). They are 6.6mm diameter but he Esky ones are 6mm. I use the fineside of my wifes nail file to carefully take a little off the whole of the outside. I use the old feathering shaft I've just removed to hold it while I remove the small amount of rubber all the way around. Keep checking the fit in the head to make sure it's snug but won't bulge out when you tighten the screw/nuts on the feathering shaft..
Great Vid , Just need to know is blade tracking the same as setting the pitch with a pitch gauge , to zero pitch at mid stick with idle-up ? some vids say to use this method . which is better or more precise?
I just got one of these belt cp helis as my first. However, I bought mine crashed off of craigslist. Tracking has been giving me the most hell ever & I have tried everything... Except now I think I have got it. I didn't read the manual & set the linkage rod to the preset length as noted. So one blade was horribly off. I could get them "kinda" in track, but it was still pretty bad. I noticed when I had the blades folded one forward one backward that one blade was about 2 inches from the flybar while the other was only about an inch or so if that. So I have eyeballed it to the flybar on both sides now and it looks really good. Hopefully this time it will track!
***** Tracking on the BeltCP can be a frustrating process. Make sure that the flybar is straight, the o rings are new, the links have no slop and everything else is spot on. Having being crashed, you can't trust any of the links, shafts and linkages are straight.. Best of luck!
Painless360 at 2:45, that screw is impossible to keep tight. if I snug it down, the flybar cannot move. I put locktite on it & got it as tight as i could, but still, it comes loose within a few seconds of moving the flybar. My head is 100% completely new, everything. Only thing i haven't tried yet is epoxy. It really needs a bearing. The "smooth" metal surface that it installs to is not good enough.
A small dab of something may help to keep the bearing in place. The BeltCP head isn't the best design and a lot change it out for a t-rex 450 clone head instead..
boo... i just got this one. its been nearly 2 years of trying to get it to fly... one thing after another. i'm about ready to just grab it by the tail & smash the shit out of it and send it out with the trash.

Thank you. I have been trying to track my blades for days. Finally the screws on the flybar cage were loose. Your video helped me to find the problem.
+yanleb1 Glad this helped - this is a 'classic' early edition of my help videos. Great to see it can still solve problems. Happy flying!
Your explanation is very clear and you made it easy for me to understand. Thank you very much.
Agreed! :) This £150 heli was my first 'real' rc helicopter and hot me hooked on the hobby. I crashed this thing dozens of times..

Thanks for the feedback, glad it helped.

Very good video, found my problem was the dampeners... Cheers
Hi Tony, glad you did. They do wear out faster than you think! Happy flying!
Awesome video, exactly what I was looking for to give me idea's on what to check next. Cheers
Thank you so much for your vid. I have esky cp3 and its been a nightmare trying to track and get pitch. Think im getting there with your help
nicest heli id ever seen!
Good old Belt CP...Man, that was my first helicopter..Sure is weird seeing the flybar above the rotor too.
Mick, good luck! Let me know how you get on..
great video. I realized That i had bad damoners for a long time. I just never took the iniciative to replace them. How did you shave them down?

They can be frustrating. Mine taught me a LOT! ;) Nice to fly when you get them dialled in though..
Thanks for clearing that up for me , now maybe i can get this bird in the air ,,,,cheers
