Hello pzrwest,
Is your question will the HL boards handle the original stock motors and gearboxes in the Stuart.??? Don't have an answer
for you on that but if I was to make a guess I think you may have problems trying that. (just a guess). Mabe Darkith,DAP,or a couple other's on the forum may be able to give you some good info on this.I think this would be a big load on any of the HL components,as you know these are pretty big tanks and they are heavy.And also congradulations on getting one of these great tanks.
