At the March ECMT meet I was asked this question.
First remember that a 2 Cell Lipo and a 6 cell Nimh of equal capacity will have a similar
run time.
The motors I think will work are a Hobby King TR2209/28 or a AXI 2212/20 both these motors are 1050 RPM/Volt so the outbut speed is 8280RPM.
These would be used with a 4-1 gear box
Use a Hobby King 18A-SL car speed control ( this has forward reverse with brake) you will also need the HK TG-PROG programming card.
If this was me I would order all from HK
This is my best guess as I run my trucks on 12 volts
If you go with this let me know how it woks
