Trent lifeboat Still under construction at 12 Months in.

Nearly finished at 3rd July 2013 - just the final touches.

First sailing 1st August 2013 - Sunny and warmest day of the year.

Using a 3.7g micro-servo. it is possible to install this small unit within many of the existing model Radar parts or scratch built models to create a working model Radar setup.

Here is an example of one fitted to my RNLI Trent lifeboat. I am using the bottom of the servo housing to clamp this unit to the underside of the base of the kits Radar platform, this helped to reduce the overall height and to maintain the scale size.

These servos are available on eBay at £1.89 including postage from China or Hong Kong.

I found this easy to mount and I have kept the servo electronics, connecting this servo to a spare channel on the receiver. This enables the radar to rotated in both directs at adjustable speeds or just stopped. I usually have it adjust at slow : scale speed, setting this with the trim on the transmitter.
