I dont see any topics on the brushed versions??? I have a 1/16 slash that I modified abit. I installed the motor plate off a brushed summit so I could fit the titan 550, added the revo arms, and the summit suspension. It seems to be almost as fast as the brushless! 28t pinion w/ 45t spur. The motor never gets hot and the run time is doubled! Its a bit heavy with the dual batteries and the 550. I upgraded to the 8.4 volt packs and about to get the tires off the 1/10 slash and also purple springs with 80wt oil. If anyone else has messed around with the titan 550, holla back! To do the conversion you need the big block motor mount, the smaller reveiver box, the gear cover, and the titan 550. All can be found on the brushed summit or boss mustang or fiesta. Much cheaper than brushless! Plus extended run time without overheating!
