Flashed BLHeli and have a tail wag issue

[JonJet]

A friend sent Me his mCPX with one of those PnP BL conversions installed and I've flashed BLHeli v13...

It's got some tail wag, and I don't know if it's mechanical or if there are some BLHeli settings I can adjust...both motors are connected to the oem board connectors to maintain the PnP status...

Can anyone identify this ESC? (BLHeli says it's XP7A)

Anyone know what BL main motor has a gold mounting as seen in the picture below?

Can you identify the tail motor?

[Heli+yeah]

First I would try pushing the rear rotor blade on further along with a tiny drop of CA glue. It looks like it might be slipping.

The rear motor looks like one I bought from HK. Mine works good with an RRC 65mm blade and an HP05 on the main.

The tail motor shaft is very long...and the Lynx rotor was not slipping

It is however not enough...as you suggested I tried a RCC 65mm and 95% of the wag is gone @ 75 flat...

I just need to fix up the wire harness now and check it again...

I should have known this...but it came from a friend and I thought it had been flown this way...I found out late last night that he got it long ago and was never able to get the flashing done, so he sent it up to Me



Thanks for the tip !

The ESC seems to be the Origin Dual Brushless ESC liek here:

I would suggest to try PWM Frequency=damped light for the TAIL.

Thanks...I see that the main motor is 289000004 also from Hobby King...14000KV
