Hi all, Just recently purchased a granite mega for my son. Less than a month old. First disappointment was a 10 run time with stock battery, but OK....got a new one ordered. The truck had less then 10 runs on it and on the last one the motor started smoking 10 mins into it. The upgrade chart shows next upgrade being a 7 cell battery so I bought a 7 cell 4200 mah battery so we can actually get a reasonable amount of time to run the car. It is stock geared at 15 tooth which should be good to normal running around and bashing which is what my son uses it for. I am currently working with tower hobbies who I bought it thru to try and get a replacement motor but will it hold up to the new battery? According to arrma upgrade list it will but now I'm worried. I will probably be getting the aluminum heat sink motor mount but now that's just another $20 on top of the $35 I had to spend to get a reasonable reliability and run time. Almost starting to think maybe I should have just gotten him a stampede like I have which I haven't had any problems with at all in its stock form. So. I guess now that I'm done with my mini annoyance rant my questions would be. Will the stock brushed motor be able to hold up to a 7 cell 4200 mah battery full run time as the chart says it will? Or do I need to look into spending even MORE money to get a brushless set up to run with this new nimh battery so it does have better reliability. I don't want to overkill it as my son is 5 so the brushed set up Is plenty powerful for his purposes. We chose the granite for him.based on the chassis strength and reviews but now I'm a little worried about the power train costing me an arm and a leg. If I was to upgrade to a brushless set up what would be the least expensive but reliable and controllable for my son? Thanks in advance for the advice and sorry about the long post. Will see what tower can do at least for now to get it up and running. He is pretty disappointed that it's broke.
