540 or 550
 

I got a HPi maverick that comes with a 540, kinda fast.
Then I got a redcat Blackout with a 550, its faster.
So I put a Blackout 550 in the maverick and got a little faster.
Then I got a redcat Volcano that came with a 540.
The Volcano is definitely the fastest of the three with the
original 540. I have a 550 for the Volcano but it may not
be any faster??
I have to admit if the Volcano gets much faster, I will crash
a lot. There must be other differences, I dont know.

There is so much more that goes into a motor besides it's size. Heck set the motor specs aside and the gearing is just as important.

Re: 540 or 550
 

If everything else is equal the 550 has the torque advantage because it has more steel on the arm and more copper wound on it.

Re: 540 or 550
 

There's a few things to consider such as gearing and the kv of the motors also.

gears! of course. Lower gears would give it more squat. Half a century ago I was comping early slot cars. I geared my
8 volt Kemtron at almost 5:1. Unbeatable on the small GP tracks. Now and then the armature would fly apart. After I
learned to epoxy the armature they held up pretty good. Occasionally burn up tho.
