While I wait for some parts to come in, I thought I would ask this question:

Fun Factor Rally (4WD) and I just replaced the batteries about 4 days ago with Fresh Energizers I saw on special at Sam's. Well, 2 days ago I was running her through her paces and all of the sudden, it went Exorcist on me. It did about 15 donuts, stopped, took off and turned hard enough to barrel roll, stopped, then took off again and came straight at me... Veered waaay off course and slammed into a wall. I had the brake on the whole time on the TX but it just wouldn't comply. Funny thing was, the only visible damage was a bent main driveshaft.

So I pulled it in and tested the controls and everything seemed fine. Both servos responded like they should.

Well I bent the driveshaft back so I could do a little more testing, electronics still working fine, as soon as I fired her up, they went haywire again! Luckily this time I had my hand on it and my foot in front of it so it wouldn't be able to get away from me - and believe me it tried!

So my question is any idea what might cause this? Should I just replace the batteries AGAIN or check into something first?
