my new yellow Super Bee fly's great. everything in it is brand new right down to the last zip tie, lol. from day one... it has had this ticking noise that i cant figure out? it was a little louder yesterday then i have noticed before and the heli has only 5 flights on it. i have oiled the main bearings, swashplate, and put a tiny drop on the cp3 super motor bearings then let it sit for a day. i have checked it completely over, and over... there is nothing obvious that i can find?
it almost sounds like an electrical type of tick, but that isnt possible since there are no solder joints except for the tail motor. could this new motor maybe have a bad bearing in it? it fly's like there is nothing wrong with it, but it sounds different than the other two. i definitely dont want to take chances with this one.
it isnt there in low idle on the ground... mainly when it is in the air at higher rpm's.
any ideas?

My guess would be main gear or further up the head, rather than the motor. The motor spins far too fast to "tick"; each rev is a fraction of a second!

You can isolate whether it is main or tail, by disconnecting one then the other and spinning them sup to see what the effect is.

that is a good point Luke... the cp3 super motor would be way to high of rpm for what i am hearing. the main gear is new and has all its teeth, so that leaves me working my way from the bottom main bearing up. i will test the tail motor first, like you suggested, and eliminate that from the list. i dread tearing in to these shaft/rotor head assemblies, but it could be worse and goes with the hobby

.
thanks

I had a weird "ticking" sound on a 450 heli once and it took me ages to track it down.

It turned out that one of the wires on the ESC had a little paper label on it. It was some sort of QC tag that I would normally remove, but in this case, for some reason, I just didn't. Normally, this was well out of the way of any moving parts, but in the down-draught from the blades, it bent down and just caught the main gear intermitently. It was only when I noticed the very tip of this little label was starting to wear, that I twigged to what was happening!

yeah, i have read posts where a label actually caused a crash by coming off and getting jammed between the gear and pinion. mine is all clear. i also checked the tail motor, which is fine. i found nothing visibly wrong, so it comes down to the bearing in the swashplate or one of the main bearings. here is the weird part... if it is facing you nose in, you can barely hear it. if it is facing you tail in, it is pretty loud? this is with the canopy off too.
