i bought 3 of these motor mount one for eatch of my motors so i dont have to dissable from the motor every time i want to change my cars motor.. at this price its excellent value for money...cools your motor and is lighter than the stocks ones made from plastic...
Previously I use the stock plastic motor mount. After more than 10 battery packs run, my spur and pinion gears are wear off quickly. I decided to replace all new pinion and spur gears and upgraded this TAMIYA (#53666) Metal Motor Mount For TT01/DF02. Guess what, my spur and pinion gears lasts much longer. This hop-up option is a MUST for prolonging the lifespan of pinion and spur gears and it is reasonably priced.
it surely is a must for the BL system upgrade but it sort of has a minute play compared to plastic mount. The reason it wobbles a bit is cause of tolerances in plastic chassis designed for plastic mount. A little amount of thread lock in the grove where it sits solves the problem. If you want to use the spacer for the motors, get a metal one as the paper one would not help in heat dissipationfrom motor to the metal mount,
as the use of a cooling device for my motor it also makes your tt01 look alot smarter when someone asks you to take it apart to show them, as a tamiya product for a tamiya car it fits like a dream and all the holes are in the correct possition which is vital for gearing so your gears can last longer without stripping
As with many other TT01 upgrades, this one is essential before changing the motor or gearing in your chassis.
A more powerful motor, or a motor geared lower, will generate more heat. The use of a metal motor mount helps work as a heatsink to cool the motor down. Also, when using the standard plastic motor mount, the heat can cause it to warp.
The only bad thing about this motor mount is that it does add extra weight to the chassis.
