Never ever!!! use KO servos in a 1/8 buggy!
Seriously...I had big problems this summer with a PDS-2143. Great servo, super fast and strong...but I kept stripping gears...3 in two weeks. The final straw...one of the popular magazine writers was at my track one day. He sees me takin my radio tray off, cussin, pissin, n moanin n what not. Asks me whats wrong, so I told him bout my problems. He states that "it is generally accepted" by many, that for whatever reason, KO servos just dont like being in offroad vehicles.
