You gotta consider what is included with a RTR ..the stock hellfire engine and servos are nearly worthless, same goes for the radio.. so in essence the only thing truly worthwhile is the roller itself..... As a general rule RTR's are not worth the hassle and extra cost, the manufacturers use the lowest grade engines and electronics, which usually do not last long and end up needing to be replaced anyways... as well a RTR Hellfire is very fragile and nowhere near as durable as a Pro level machine...... I am not trying to be a jerk to you, I am just trying to offer you some sound advice to maximize the money you are spending...
