TRF 503 @ Nürnberg 2014

A bit late posting about the actual TRF503 release now that it’s finally official, but this is because I actually went to Nürnberg to have a look myself.

Below some good pictures of the car from Tamiya and tamiyablog, as well as some of my own (excuse the bad phone cam quality).

My own comment is that the car looks very good and feels very good so I think Tamiya have a great car coming here. I was very impressed.

42275 TRF503 Chassis Kit

Tamiya USA:
This is the all new TRF503 4WD racing buggy. The 503 has been developed thanks to the Tamiya Racing Factory team once again putting its extensive race and testing experience to use for Tamiya’s racing enthusiast customers. The TRF503 off-road chassis is an updated and modified version of the TRF511 that promises to have more traction and improved cornering ability.

More on TRF418 Battery Stoppers

Day of many updates today it seems!

As promised, here are pictures of the inner stoppers I use on the 418.
Forward one with a screw in the servo mount and appropriate number of spacers to get the battery where you want it. The rear one (not mentioned in the manual) is a similar idea mounted to the center support, but with a small bearing added as the belt is very close.

TRF Short Dampers

Tamiya recently released the shorter TRF TC dampers, which comes standard on the TB-04 PRO, as an option part.

Tamiya already did damper stays for the TA06 for these but so far no news of TRF418 parts to fit these. The dampers are 4mm shorter (also noted on the back of the package as you can see), meaning they are 57.5mm long, which is exactly the same as the shorter Yokomo dampers now also available for the Yokomo BD7.

In the pictures below the dampers are set at 57.5mm with the included Tamiya yellow springs. Option parts used are HL Cylinders and 1mm down alu spring retainers.

42273 TRF Short Damper (Hard Black Coating) 4pcs
42272 HL Cylinder for TRF Short Dampers (2pcs.)
53876 Aluminium Damper Retainer (1mm down type)

TRF417FF Winter Sleep

Just a couple of pictures of the TRF417FF in it’s latest state.

This is how it looks after the last run of 2013 which was late September. I will run the car again once the snow melts and spring arrives.

As you can see from the bottom picture, there’s no wear on the chassis OR bumper. A big difference compared to the normal FF cars.
