Electricity surge

[Tavo]

When I use RCS64 on either Practice or Race modes on occasions the second the screen start light turns green there is a surge of electricity before I pull the trigger. It happened infrequently in the past but now has occurred twice in the last 2 days. Occasionally this will happen also after the start of the race; have already damaged one rear wing so hesitant to use RCS64 now.
When racing without turning on RCS64 I have no issues whatsoever with electricity surges anywhere in the track.
My track is about 85 feet long, Scalextric digital with a c7042 powerbase; do have three jumpers throughout the track. Use standard Scalextric power sources.
Thanks

I would guess the Controller is calibrated wrong try recalibrate them.
