I got a HPI RS4 2 the other day. One of the AA batteries came loose while I was driving it. Lol...when I was at WOT.

Luckily, we have curbs that are sloped up. The car was running probably about 30mph when it jumped a curb and landed up side down. I don't want this to happen again, because I may not be so lucky next time.

What can I do to keep the servo from staying at WOT if I lose power?
