Links | Tamiya TT02R Opel Calibra

This is a Tamiya TT-02R radio-controlled (R/C) 1/10th scale on-road car (Tamiya) with a lexan body of an Opel Calibra.

Several updates and other additions were made to the car:

The car is equipped with a T2M T49014 Rush TETC sensored brushless electronic speed controller (50 A / 300 A, 2S, 6V/2A BEC) with a suitable T49015 programming box (manual).
All Tamiya-style battery connectors were also replaced with IC3 ones (capable of handling 60 A continous current). They have been treated with silicone for smoother (dis)connecting.
The following motors are available:

A T2M T49010175 Rush stock SE 17.5T TETC sensored brushless 540 motor (2200 KV, 130 W, 34 A, 1-3S).
A RUDDOG Racing RP542 10.5T stock sensored brushless 540 motor (3600 KV, 1-2S).

The bevel gears inside the kit-provided differentials are replaced with GPM TT2100/G4 steel small bevel gears.
Both the motor and the ESC are cooled by Yeah Racing Tornado high speed cooling fans. For the motor, the fan is mounted on a Yeah Racing aluminium fan mount.
In order to monitor the state of the LiPo battery, the car is equipped with a FlySky FS-CVT01 voltage sensor that sends telemetry back to the transmitter for real-time monitoring.
In addition there is also a FlySky FS-CVT01 temperature sensor attached to the motor (using kapton tape) to send further telemetry back to the transmitter for real-time monitoring.
With the current gearing of a 64T spur gear and a 29T pinion gear (final drive ratio of 5.74:1), in combination with the 10.5T motor and a 2S 5000 mAh LiPo, the car now reaches 68.5 km/h.

Controlling the vehicle is done using a FlySky FS-G11P transmitter (manual) and 11-channel FS-R11P receiver (manual).
The steering servo is an Amewi 4409MG AMX Racing 9 kg low-profile digital servo with metal gears, combined with a hi-torque servo saver and aluminium horn.
The front plastic suspension balls were replaced with low friction suspension balls.
The front (and back) upper suspension arms were replaced with adjustable ones to allow for camber setting.
The steering bridge was replaced by aluminium steering arms and steering bridge.
For the steering linkages, the plastic pivots were replaced with low friction step screws. In addition, the stock steering arms are replaced by 5 mm short adjusters with 3x23 mm aluminium turnbuckle shafts.
In addition, a Yokomo DP-302 V4 (manual) aluminium drift steering gyroscope (with slow-return assist mode) was mounted for steering assistance.
A SkyRC GSM-015 GNSS speed and GPS positioning sensor can be installed to allow full trajectory sampling up to 10 Hz.

The chassis was reinforced with a Yeah Racing 2.2 mm graphite upper deck.
The front bumper stopper was replaced with an aluminium bumper stopper plate and a TT01D urethane bumper was added to the rear.
The body of the car is an Opel Calibra V6 Cliff, custom painted in the colours of the Belgian flag and reinforced with versatile glass fiber-reinforced aluminium tape.
In addition to the stock wheels and tyres, the car can now be equipped with medium-narrow racing slicks, medium-narrow racing radial tyres, mounted on medium-narrow 10-spoke wheels. The tyres can be treated with an MR33 Rheinhard V3 asphalt additive for more grip. In addition, there are also Team Corally Attack 35 shore front (26 mm) and rear (30 mm) foam tyres with carbon rims.
The slop in the front and rear out drive shafts was removed by coating the insides of the hubs and the shafts with a small layer of superglue, and by painting the outside of all bearings with a black marker.
The inside of the car is also equipped with a chassis cover set to mitigate dust entry.
