Academy SB V2 PRO Motor question

[DrKnow65]

The SB V2 is a racing buggy. It's light and agile and can offer alot, for something that weighs less than a nitro conversion. Steel spider gear diffs are great for lasting through tons of abuse, but does anyone make one small enough to weigh what a ball diff weighs? The whole point of this buggy is it's ability to turn fast, on a dime. Tight tracks like the ones available to me don't work for 1/8th buggies and I havn't found a 1/10 4wd nitro buggy that could be converted to compete with the buggies in this class, on this track.

There IS a need for strong ball diffs, but it's not impossible to get one to last in a high torque, high speed 1/10 4wd buggy.

Not to be too defensive... suppose it's too late for that :)
