No steering under heavy braking???

[Chesty]

Hi

Gave the B-Max a quick pre-race blast up & down the hallway.

Noticed something that's never happened before, under full braking the steering wouldn't function for a couple of seconds, was as if the servo was starved of power?

I'm running Novak GTB combo, Sanwa 431 rx, HiTec 5925 digital servo & NiMH batteries.

I've ruled out the TX because it doesn't do it with my 2wd, I'm wondering if the speedo's power capacitor isn't charging or not charged enough to power the servo at that point?

Anyone got any ideas or experienced the same, any help would be much appreciated
