Havok sc pro 550 4.5 shuts down my receiver every lap or so for 1 to 3 seconds with 5400 25c lipo 2s. I changed to 5200 35c 2s and problem goes away. Go back to 25 c problem comes back. Any thoughts. Would esc timing have any effect. Just curious I now run a 5600 50c 2s w/o any issues. Seems like 135a would be sufficient but is not?
