Revving at low speeds is going to heat up the clutch with just about any setup (nitro too) and isn't a good indicator for operating temperature. If you're doing mostly low speed driving take the spring off of the clutch shoes or use a pinion. Your spring may need replacing if it had moderate to extensive use when your Revo was nitro.

Try no spring and if that doesn't drop the temps, send us an email and we'll send you some new shoes to try.
