ok so i am now getting confused and with little help and money burning a hole in my pocket ,i dont want to make the wrong choice but i do want to make one!!....i want to do very high speed runs in a 1/10 bj4 like i say the velineon will do high 60's low 70's but i would like something much, much more powerful with a motor that fits in my bj4...im open to ideas ,i have been looking at the mamba max's but they top out at 60 mph as a system,exceed 3.5t systems look quicker but are only 2s so will that be a factor....like i say any help would be brilliant as ive had 57 views and no comments ...come on lads give me a hand
