Tamiya TRF 417X Chassis Kit


Tamiya never stops innovating, the new 417X was just announced at the 2011 Tokyo Hobby Show. The 417 has been updated and upgraded with a newly designed lower deck, this helps to improve flexibility for better low speed traction. The previous one-piece motor mount has been replaced with a three-piece type to allow further adjustment of chassis’ flexibility by linking them together. The thickness of the front and rear damper stays have been increased to 3.5mm and other new developments include a new upper deck, metal battery holders which serve as counterweights, and low-height kingpins. Front direct coupling and rear gear diff unit (Item 42197 TRF417 Gear Differential Unit II) are included in this latest spec version. With all the adjustments available on this chassis, it may turn into one helluva the drift machine!
