Does anyone have good BLHeli 12.2 params for the HH blh3327 motor and xp3a esc? I put this setup on the HobbyZone Sport Cub. Without the gear box, the motor starts and stops fine without issue. When meshed with the gear box, I sometimes get the screech of the motor not starting. Giving the propeller a little spin first gets it going fine. Once running it is fine. The only issue I have is with the startup. If I move the throttle up slowly from zero, it usually starts fine as well.

Thanks!

Oops...misread your question.

Which firmware are you using. Multirotor code or Tail?

Try the tail code if you haven't already. It's the most basic and applicable to the needs of a airplane.

It was developed for the brushless tail motor of a CP heli. So the response is instant.

I'm using the multirotor version. I use that on a lot of blue series 12a esc's and small high kv motors and it works great!

My only problem is the startup. Once it's spinning everything is fine. The throttle response and power is good and never loses sync. I'm not sure what to adjust so I don't screw anything else up.

Tail code didn't really work. It would sometimes stall and screech upon initial startup. Also, once spinning, the motor wouldn't shut down.
I put the multirotor code back on and played with the startup power - still got several non starts. What finally worked was setting the startup method from direct to stepped. Now it starts every time. Not as smooth, but reliably.

Hi guys, can somebody please help me

This is what I have assembled so far.



I intend on running a nCPX BL motor off of a YEP7a, but on an airplane and using the brushed output of a built in ESC for signal.

What parameters do I need to change in the BLHeli Suite? Should I try the tail or multirotor code?

My goal is to free up a channel on my RX because I currently have to mix throttle to flaps and plug my ESC into the flap channel.
