Suggestions for a new E-Maxx controller??

[Z06jim]

Thanks, I thought that was the case.
Motor cells Voltage KV rating Motor RPM
Wanderer 9L 5 3.7 2512 46472
Wanderer 7XL 5 3.7 2145 39683
Wanderer 8XL 5 3.7 1875 34688
Wanderer 9XL 5 3.7 1667 30840
Wanderer 10XL 5 3.7 1502 27787
Lehner Basic XL 2000 5 3.7 2000 37000

Still Like the thought of the 7XL over the 8XL
Only 5000 more rpm

What about the Quark controller?
