The MAM is a great 8scale kit as many other 8scale kits are also. Regardless of what mods may need to be done to this kit... it needs far less mods than ANY! traxxas product... especialy in terms of handling more power. The pure GRUNT power of the xtm 24.7 engine is FAR beyond what ANY .15=2.5cc engine can make. What the MAM has going for it is a lower CG compared to some other m/t kits, gearing is to high imo, by using a smaller dia tire will make a big differance in excelleration/grunt on this kit 50mph is geared to fast anyway for most tracks/parks...

IMO, just stay away from the small engined 10scale stuff. their drive train parts are only DESIGNED for the small little .15 engines =(2.5cc) and at least the 8scales are designed for the bigger power and grunt of the .21 to .27=(3.5cc to 4.6cc) engines.
