2 questions on some troubles

[pscm]

I have noticed I am getting sudden motor shutoff on first spin up. Usually as I am bringing throttle up, get an occasional couple of burps. Once flying it is fine.

Second question is I am seeing blade track is off and don't see any way to adjust. What would cause this?

The motor could be going out causing the stoppage. The blades can't be track adjusted on this one your best bet is to try to bend one of the blades carefully. Or your spindle may be bent and need replacement.

Blade tracking tends to be bent spindle. Replace new or bend back.



Blade tracking could also be unbalanced blades (see recent thread on mCPX servos for more details).

Motor shut-offs could be damaged battery cable or bad solder connection to 3-in-1 board.

Thanks I will check.

My nano acts the same way on spool up, check for loose connections at the battery connector and at the main board(a little hot glue sometimes works well at the board), a motor on the way out can cause this too but mostly i found that its the batteries that cuase it,batteries that seem to work fine in the msr or mcx etc may not work as well in the nano- shes a power hungry little beast.
I picked up some of the new 45c ones from eflite yesterday,havent tried them yet but they should make a difference-hopefully

I have also read in another thread that the main board can have a slight crack or a component becomes loose from the canopy hitting it during a crash

Interesting on the batteries as I thought one was more prone to this than the other but as of late they both do it now the one more so than the other. I think I will take the kids qx batteries and try them.

I have confirmed a bad battery. And checked the spindle and straightened. Still haven't solved my vibration problem that I have posted separately.

You fixed your tracking already but another thing I've found that will set tracking out is if the little pitch links get bent in a crash. I've had a few I didn't quite notice, one of them actually bent in towards the main shaft, so from the side it looked straight but was bent in enough to cause a definite tracking issue on that blade. You can straighten them or simply replace them.
