Speedo too hot?

[Promod]

A 7XL is way to HOT for 18 cells. Try a 9 or 10XL. With the right gearing the slower turn motors will be just as fast(if not faster),have longer run time, and not beat your speed control to death.
Schulze speed controls are good but there customer service is horrible!! If they fix it under warranty it will be a shock to me!

Thank you,
