i have a mini t that i just ut alot of alum on and i also got the mamba comp x and i was wondering what type of batterys i should use i have a dynamite 1200mah battery but its really slow and i have it programed for the fastest i can go. i think it might be the battery going bad i have had it for along time and i think it time to get a new one so if you guys have any idea of what type of battery will make it go better please let me know. as for cost i dont want to drop more then $50 for the batt. but i want it to be stupid fast like all of the other minie t's out there that have the same set up. thank you
