Changes to the UK  rules.

Our BMFA now allow 2.4 mghz radio to control non-flying functions on Control Line Scale models.

This opens up many possibilities for scale fliers that have previously tried 3-line and Servo Testers to control just a single function of their models.

The transmitter and receiver work as a normal radio control unit (with the associated servos) to control function such as throttle/drop tanks/ bomb drop/ flaps/retracting undercarriage.

The main flight controls must still be still through the handle and lines.

U/Tronics

U/Tronics, an electronic system from Clancy Arnold in the USA.

A proven electronic system that Clancy has produced and sold since the 1980's. It works like the Bek 4 system and controls normal R/C servos within your model.

There is a Single Channel unit and a Multi Channel Unit (available in 4 to 7 channels).

Some work with a soldering iron will be required, comprehensive instructions are provided for both the single and multi channel systems.

Contact Clancy through the details above for prices and more information.
