    4000kv i would think wouldnt have enough torque for a 4x4 the velineon is 3500kv. if i were you, running a 1/8th scale track, i would go with a 2400kv castle motor. or if you want go with tekin. they make motors and speed controls for buggys.

    Are you talking about Tekin products? If you are, I would suggest the 2650 system. It is designed for 1/8 th scale rc vehicles.

    The 4000kv set up works well in the slash for bashing and some track use, the 4600 is great for the track and specially tight turns where you can gear it down to controll heat and not concerned about top speed

    +1 on the RX8/T8 2650 combo. Thats what Im running. Smooth on and off the track. A few setup changes and I can go from race ready to an afternoon of bashing.

    You have to watch what tracks you go to though as some dont allow anything larger than a 550 can. In that case I would go with the 4000kV

    is a 540 smaller or larger than 550, because my track is loganville speedway, and its only allows 540 motor

    What do you have to change to use the rx8/t8? I want to use a bigger can motor.

    A 550 is longer then a 540. They are the same size around but length is the difference. A 550 will have more torque then a 540 motor.

    Tekin Pro4 motors are simply an short can T8 540 size, with a 18.5mm rotor. I run a 1/8 th track and use a 4000kv geared for 35mph, highest temp Iv seen is 150ish. They come in 3300kv 3cell, 4000 & 4600 2 cell max. It needs to be paired with a 1/8th ESC, MMP & RX8 are mostly used. At the track there are some 4600kv running but have no advantage over the 4000kv, at my track. As they say you can always turn it down, but not up.
