Team Associated RC10 B4.2 RS RTR - 9042 / 9042C

   Introduced by Team Associated in 2013, the 2WD RC10B4.2 RS (Race Spec) RTR - # 9042 - came with a Reedy 3300kV brushless motor, XP SC500-BL ESC and XP 2.4Ghz radio system.

   An RC10B4.2 Brushless RTR LiPo Combo version - # 9042C - was introduced in 2015, with the same spec, plus a LiPo 3300mAh 7.4V Battery and a Reedy 324-S Balance Charger.

   In this series of articles I will endeavour to provide information to help identify any of the 1/10 Scale RC10 2WD series and where it sits along its evolutionary trail. With this knowledge, any RC10 owner should be able to decide if their model is just one of the many thousands that were produced, or is potentially a collectors "holy grail".

Information and Advice

Electronic Speed Controllers

   ESC were originally developed to be used in conjunction with brushed 27T stock and modified motors in the late 1970s, early 1980s. Compared to modern day Controllers, they were Bulky and heavy, constructed using basic resistors, rheostats, capacitors and transistors, crammed together on a simple circuit board, to provide stepped but smooth acceleration when compared to the old mechanical, servo operated sweeper Speed Controllers. An Electronic Switch to change the direction of current flow was used on some of these early ESC to give reverse operation. Although they were a vast improvement on the old mechanical speedos of the time, they were expensive, jerky to control, and prone to burn out if not carefully looked after.

   As new technology became available, improvements were slowly made, and with the introduction of the new FET (Field Effect Transistors) and some basic mass produced silicon chips, ESC were made smaller and their reliability gradually improved.

   By the mid 1990s, "regenerative breaking" was developed. This meant that energy that would have been lost slowing down the car by effectively turning the motor into a generator, was harvested and put back into the battery. This of course was long before F1 had KERS (Kinetic Energy Recovery System) and adjustable anti lock breaking was introduced.

Make your RC Model Ball Bearings Work for You

   If you are serious about your racing, looking after your bearings is essential if you are to remain competitive.
   My own experience is in both Off and On Road, National and International Car racing, but most of these tips could be useful to all forms of RC.

   Shields: The main problem with Ball Bearing Shields is they create friction, and obviously the more you can reduce friction, the more efficient your bearings will be, so here's a tip that does just that.
   Wheel Bearings always come in pairs, positioned side by side. If you think about it, the two inside shields on each bearing are not required, so ... you can remove them using a small jewelers screwdriver ... simple. And in one fell swoop you have halved your wheel bearing friction.
