Savage BL motor mounts...

So best to use the hd 2speed w/mechanical brake overall then right? I know i want more speed than less of it -lol-

Is reverse hard to throw into the above mix? Just have to add the 'reverse gear module' and a third servo/channel right? Or does it get more complicated than that with placement etc?

Ideally i would like reverse, but it isn't going in if there's more than minor mods that would need to be made, or if it would hinder performance in any way...
