It has a $600 high performance engine, exhaust, extra set of brand new wheels and tires still in the bags, aluminum work stand. At least $2,500 worth and got it for $550. I saw where some have had trouble with servos. Owner told me that he can hear a slight bit of noise in one and I should replace with metal gear servos. Some say I should go with a single servo because they're having trouble with them fighting each other. Is this hard to do? I will probably need to do something soon. Any help would be appreciated!
