ok....I didn't say I don't think I said I turned it in...Sorry if I did say that, but I was turnin it out. And Even though the engine should run a bit hot, I don't think it should be going to the 300's....Which it did. I don't know if it's defective or not. I can't run it today cuz it's raining...LoL...raining on x-mas day. But I will run it a bit, try to turn it out some more, do anything I can to get it to cool off. If I can't get it running correctly,.....ummm.....would Traxxas give me a whole new engine or just the carb??
