I have an RC truck that I used to race competativly when I was younger (14-16 years old). Just before I turned 17, the two local tracks I ran at closed within 2 months of each other and I had no place to race. So I was reduced to pounding around my backyard with a disgustingly fast electric RC stadium truck. It got pretty beat up in 3-4 years and I was replacing the usual wear and tear parts (do you believe that tie rods were considered wear and tear on the truck?) but nothing major ever bit the dust on me. The truck was 5 years out of production and parts were very difficult to come by. I guess it is a testament to the quality of the truck that it worked so well for so long.
Anyway, the transmission ate itself up. The diff plats got scored and would not spin properly on the shaft that they were supposed to ride on. This ended up causing the truck to lock up one wheel while the other spun. It would make nothing but left turns even with the wheel turned to the right. The gears ended up stripping out and it was a real shame. Even at 6 years old, the truck was still very competative in its class. Lack of availability in parts meant that it wasn't going to run again for a while.
Well, the other day, I looked at eBay on a whim and found a guy who was selling a complete truck, just like mine, with spare parts and electronics, including a controller. He was cleaning out his basement. So I grabbed the whole kit and caboodle plus a pile of spare parts for about 120 bucks! Now I'll have 2 trucks on the same chassis with a good transmission and a ton of spare parts!
A bunch of people here at work have the gas powere RC trucks and they all tell me that the electrics are slow but they haven't seen a decent electric put together well. No I can fix mine and show them what a real electric RC truck can do! I'm like way stoked and I can't wait for the truck to get here!
OK, enough of that. Back to our regularly scheduled programming!
