Cogging with Fasst on HRS- Speed Passion

[scaramanga22]

Hi Guys,

today i installed my new Speed Passion GT LPF1.1 speedo
in my BJ4WE in combination with an CS-Electronic 5,5T, 5cells
and sensor cable.

i have a 3VCS with fasst module and receiver, i ran it with HRS mode
since now without struggles on a GM Genius 95.

I made the radio setup to the speedo and test it in the backyard
and had massive cogging under hard accelleration.
I installed an extra cap on the receiver, no change.

Then i changed on the Transmitter to PPM mode, cogging gone.

Strange Problem, have anyone the same???

Thanks for any help,

Thomas
