Servo glitching after installing Hobbywing v3.1

[jo90]

Since switching from the Tekin RSPro to the Hobbywing v3.1 I have found my servo on both 2 & 4wd glitches like mad. This is mainly when going to full left or right. Both servo's are brushless high volt/high torque but this never happened while the Tekin was in place. I swapped over due to the HW having more bottom end feel which is better, but this glitch business is doing my head in now.

I have run power caps connected to both cars recievers.

It's a KO 401f receiver in both, in the 2wd it's an Xpert PI-3401 and in the 4wd a Futaba BLS156HV.

Im guessing the HW doesnt have as higher power BEC output perhaps but its not ideal whatever it is. Has anyone else come across this before ?

Cheers
