Some advice and words of wisdom please.

Ok great thanks so you are running these motors on 22.2volts Hell that must make em fly!!!!

The Quark 125B speedo and a Feigao 10XL motor running on 6Cell would do the job for bashing on an E-Revo?

6s is definitely an option, but it depends on the motor you will use, specifically the kv rating. The total rom of the motor = kv * battery voltage. You want to keep the rpm ~35,000-40,000 rpm. Also, be careful when picking out your ESC. The Quark is only good for 6s according to the site. Personally, I don't like to run things to their max ratings for the sake of lengevity. So, if you plan on maybe running higher voltage later on, you might want to consider an ESC that can handle high voltages right off the bat. However, if you are sure you will never go any higher than 6s, then the Quark will be perfect.

Thanks Brian, so I should choose a Motor Batery combination that holds at 35,000-40,000 with ease (for long life) and a speedo capable of runing that also with ease (for long life). That makes sense! Cheers
