Poly-Tec Brushless Control 70-18 Pro

After I have configured all the functions of the regulator including the stop and full position of the engine, I connect the regulator to the RX and try the engine makes a few turns it stops and the engine emits two-tone beeps continuously

I tried everything on the radio configuration without solving, what am I doing wrong ?

Thanks for your help

The controller is connected to a Poly-tec 480-23 XL, the same configuration (motor, controller, radio) is used for another glider I don't have this problem
 
Hi Peter, sorry for my delay answer, i forgot to select the number of lipo cells during setup, now it's ok

when i connect the battery the controller should emit beeps counting the lipo cells? it does not do it

Ths
