Hey y'all....

looking for an answer to this problem.

I have two different Blitz trucks, one has a reedy 3300 kv, and one has a castle 3800 kv motor, both with Castle sidewinder ESCs.

If I run them on 2s, no problem, but 3s will eat a stock HPI plastic spur, on either truck. in a matter of minutes. I have set them using the paper method, I have set them by feel, I have tried different pinion combos, always the same result.

These trucks were both blitz that I converted to brushless, and the blitz flux has the same part number for the spur, so evidently there is a way to make these gears hold up to brushless power. Robinson racing no longer makes the upgraded gear/slipper combo.

Does anyone have any input as to available upgrades ?

Thanks.
