I know its not an ST but I had to post anyways. My son had a highly modded electric stampede and he wanted a nitro. I said I would sell his Stampede on ebay and buy him his first nitro truck. Well after looking at alot of brands I did not want to spend a ton of money on a name brand. After doing alot of research I ended up with a Redcat Tsunami. Not expecting much of it I was very surprised once I received it. The quality is alot better than expected and the Taiwan cxp.18 engine has to be one of the best running engines I have had to tune. No kidding! I know it sounds odd but the motor runs very smooth and tuning was a snap. Once I fueled the tank I primed the line and 2 pulls it was purring. I broke it in and the power is very good and getting better. I would have to say the speed so far is in the mid 40mph range. The only thing I had to do was put thicker shock oil and some minor adjustments. Its not quite hobby grade but its damn near close. They did alot of right things when building it. Steel axles and drive shafts, ball bearings throughout, shock towers and body mounts look very strong and electronics respond well.. The best thing is the motor. Time will only tell how it holds up. Here are some pics.
