I bought a TA-01 Michelin Pilot Ford Escort Cosworth on eBay for just under £200. It had everything and was in reasonable condition except for the perished tyres, an unchangeable battery, and the unreliable MSC.
I upgraded it as follows
Etronix Probe WP Electronic Speed Controller
Tamiya RS-540 Sport Tuned Motor 53068
Tamiya Ford OZ motorsport wheels
Rally-block tyres
HPI Plazma 7.2v 4300mah NiMh Stick Pack Re-chargeable Battery
RW .6 Pinion 19 teeth
Bearing Kit
50529 Plastic gear set
Blue 45 degree body pins
Aluminium Servo Mount - blue
Aluminium Wheel Hex Drive Adaptor With Pins – blue
Yeah Racing aluminium steering set – blue
GPM Aluminium Front hub carrier – blue
GPM Aluminium Front Lower Arms - blue
GPM Front C-Hub Aluminium – blue
GPM TA01 Alloy Front Gear Box BottomGPM Alloy Front Gear Box Bottom -blue

Yeah Racing Aluminium Rear Lower Arm Set blue
Yeah Racing Aluminium rear differential cover – blue
Yeah Racing Aluminium motor mount- blue

GPM Racing 60mm Aluminium Adjustable Shocks - blue (silver springs)
I then fitted a top Force carbon fibre chassis using the following:
Fibre Lyte Top Force Carbon Fibre Chassis
ORB Racing Top Force Evolution J-Parts
Top Force Evolution Deck Mount Bag
Then it was converted to brushless using the following:
Leopard SKYRC 3300KV 12T Brushless Motor
Leopard 60A ESC Speed Controller Combo ME716
Next I intend to upgrade to a LiPo battery, modern radio gear fit some adjustable turn-buckles
What else should I do?
