Dynamite .21 RTR Nitro Engine w/Pullstart
Long story short, I wanted to get into Nitro buggy, but didn't have a disposable income to throw at equipment. I picked up this Engine, and paired it with the Dynamite Platinum 1/8 053 Mid Range Inline Exhaust System. It was very cheap, and I could break in the engine prior to purchasing a starter box. I installed the pipe's O-Rings with some bearing oil (Schelle Racing Black Diamond), and fired it up. Took a few good pulls to start the first time, but had her up and running for break-in. 4 tanks later, she was ready to rip. I got about 12 tanks of practice in before the pull-start system started to get a "catch" on return. I cleaned out the system with compressed air and it seemed to do a little bit better, but wound up purchasing the Dynamite Pull Start Eliminator Backplate so that I could use a standard bump-box. Powerband is very good, and robotically consistent. I have one of the fastest buggies down the back stretch at our local track, and in our travelling series. It gets around 10 to a tank, which isn't exceptional, but nothing to scoff at, either. It was very easy to tune, and seems to have maintained a good pinch after 1/2 gallon. Temps hover at around 240, which as I have heard is the "sweet spot". Very impressed with the overall quality of the unit, but you may need to remove the pull start rather quickly. For 1/6th of the cost of a new O.S., I have received similar performance. Would purchase again.
