I realize this thread is about the 1/10 trucks which seem to be having a lot more negative feedback than the buggies...especially the 1/8...but I am here addressing the controller issues...

Send it back in to Redcat and let them replace it...although...more than likely it will be the same controller (just like the one that came with the truck) so people may STILL have probs if these are replaced with the same type/brand..

As with MOST "ready to run" kits...the electronics in them are pretty much just obligatory to back up the "ready to run" claim...although it's a nice gesture...in essence...they suck...

I suggest doing what I did...before I even STARTED mine (1/8 buggy) I went to Hobbytown and bought a good FM digital controller (JR racing) and it included the receiver and servos...all for just over 200 bucks...yes..it sucks to spend even more...BUT...even when doing that you will have about HALF AS MUCH MONEY into a good ride than you would with the more popular brands (Kyosho...Traxxas..etc...)..

Upgrade your electronics and see what happens from there.
