Reason I am asking is I have a 4.5 ballastic 550 and a 4.5 540 trinity duo 2 motor how would these compare to each other
Heat?
Run time?
Over all speed?

Also where can I get these o-rings everyone is talking about

How important is it to get the swaybars can't seem to find them anywhere.

Thanks for help
