And why is everyone wanting to convert to HL gear boxes? Did anyone her of any matorro gear boxes breaking..I didn't? I know i said that the first matorro tank out felt like it had no tork and did not turn the tank good... But that was on the first tank that ran on AA cells BUT the KT now runs on sub C cells and like with any RC product the sub C cells give your RC much more power than the AA's do... maybe the matorro gear box is in fact better than the Hen long gear boxes...at least the matorro boxes are seald and no dirt can get in on the gears...
