Another thing just take a look at the motors. I know this is a tad unscientific but doesn't a bigger motor generally = more power? Plus ask yourself if a manufacturer made a smaller lighter motor that was more powerful than a bigger heavier motor why would they make the bigger motor in the first place? So why is it not so off base to conclude that the RS 775 18v is more powerful than the RS 550 motor? Especially when the manufacturer's specs back up this idea.

Bigger motors only have more power if they aren't case shorted half the time or more.

Guess which motor has a tendency to have a case short?

How does that add to the discussion about the 775's peak power?

The 550s have other reliability issues, just more obvious and less damning (i.e. trying to stall them will quickly result in smoke, while the 775s can take more abuse. when the case isn't shorted.)

Re: pic: In_CIM_erator

Just to resurrect the discussion about whether the 18 V RS-775 motor from BaneBots (M7-RS775-18) is a Mabuchi product, see here and here for what a Mabuchi sold by a reseller looks like. You can clearly see the differences in case style from the Mabuchi spec sheet, and if you look closely at the first link, you can also pick up the (painted-on) Mabuchi "M" logo on the side of the case, with what appears to be a part number underneath the reseller's label.

So I stand by my contention that the Banebots RS-775 from 2011 is not a Mabuchi motor.
