Tamiya TRF101W Chassis - 42279 (Radio Controlled Model Review)

  Released by Tamiya on July 1, 2014, the 2WD TRF101W (Wide Tread) version, was designed to make the chassis more suitable for "foam-tire" racing.

  The model has revamped front suspension arms: The redesigned carbon fiber upper arm piece is married with carbon fiber lower arms to bring the chassis excellent durability and enhance the unit's controllability. Both the front suspension mount and aluminum servo stay have also been redesigned for the TRF101W chassis.

  Greater Flexibility: The thickness of the carbon fiber lower deck has been reduced to 2.5mm to provide greater chassis flexibility, which will provide enhanced stability on low-grip surfaces. Battery posts have been moved forward, transferring pitch loads closer to the front of the unit and boosting front traction.

  Smoother, faster dampening: The newly-designed middle brace moves the pitch damper attachment position 2.5mm to the rear, leading to faster response and keeping the car close to the track surface. The roll damper employs a new piston with equal contraction and extension lengths for smoother performance.

My First National

   When I first started in RC, way back in the late 1980s, I would turn up to the weekly club meeting, with my Tamiya Boomerang, Acoms transmitter, two sets of crystals, a couple of 7.2v batteries, a charger and a tool box with a wheel spanner and a few spares.
   It was three five minute qualifying rounds and a final, and every month we would have a trophy meeting. The trophies were donated by a two of the older semi professional guys who basically ran the club and over the years had collected what must have been hundreds of trophies and had no space for them anymore. The lure of a trophy always brought out the "not as enthusiastic types" and the small church function room was always packed on those nights.
   About a year in, my collection of B final trophies was beginning to clutter my room, and my dad bought me the new Tamiya Manta Ray. That was the big turning point in my RC career.
   From then on it was A finals all the way. Then one day in the summer of 1992 the club organisers (the semi pro guys) asked me if I would like to go to a BIG national meeting way down south in Malvern. I asked my dad and with a bit of prompting he said "why not".
   When we got to that meeting we found there were around a hundred competitors, with ten groups of ten. I was in group "H". a two of my friends went down with us and they were in group "I" so were on just before me.

Bearing Seals

   If you were to ask anyone with a modicum of experience in RC, they will tell you that the best modification you can make to a basic RC model, is to add a set of ball bearings.

   Quite a few of the entrance level models at the time this article was written, come with plastic and sintered brass ring type bearings. If these bearings are installed in the model and coated with grease as advised in the car manual, dust and grit can be caught in that grease and be dragged into the bearing where it can abrade the shaft that spins in it and it won't be long before it becomes a very sloppy fit, causing all kinds of problems.

   But what should you look for when buying bearings? There are a number of types of seal used on ball bearings, and there is much debate concerning which is the best for RC.
