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.

HI Dave
Yes the gear noise is a problem, tried to fill the gear box area with some light grease but not a good solution ..messy and too restrictive.
Going to only run the radar when under way, switching radar on via a mercury switch and the forward momentum. Noise not a problem that way and it won't wear out as quickly.
Here is a Graupner Bremen 9 converted to represent a UK Police boat. She is called DEVA which is the Roman name for the county capital of Cheshire - Chester.
If the Cheshire Constabulary owned a vessel of the size of the original Bremen 9, I am reliably informed that the 'Battenburg' and transom diagonal stripes would be correct. The 'BA 07' lettering on the superstructure is also the correct national and regional code for the Cheshire Constabulary. The constabulary crest on the cabin doors however has now been superseded by a more modern constabulary logo that looks sh1te.
The RIB provided with the kit is too small and in my opinion not to scale; I will replace it at some point. The light bar and all other blue and navigation lights work off 9v batteries.

Your model boat looks wonderful and would be a great example to show people how this model should look like. Would it please be possible to have some of your build photos emailed to us so that we can show of your great work on our new website.
HMAS Fremantle (my first build and is still a work in progress) is a semI kit, hull and some fittings were supplied, most parts have been scratched built. She is powered by two MFA RE-385 5-Pole DC Motors, each controlled by a Mtroniks MicroViper Marine 10 ESC, supplied by one 6V 3.4 Ah lead acid battery, she has a running time of approx 90 minutes on the lake.
Sorry I can't answer that, I've never used lipo's so I can't give you a comparison. I've never had any problems with the sealed lead acid batteries, and use them on all my boats, they also double as ballast, as I would rather use batteries that dead weight.
Hey there, nevermind thanks for getting back to me though, I am beginning to move away from lipo's now myself, its only because I use em on my planes & cars so I just put 1 & 1 together & came up with 11
Cheers matey

This model was built from a model slipway Tamar kit. it was modified substantially.all rails are soldered brass. info was from the website of Peterhead R.N.L.I. Station were there are excellent photos. The models engines are thumper motors 4240' at 900kv and run on three cell lipos @ 5000ma. Which give me at least an hour. With a speed of at least 10 mph, which lifts her bow out of the water,way passed the bow thruster , which is a graupner 400. Radar works through an old servo . Flashing blue light on mast. Running and accommodation lights. These boats are normally red below waterline however Scarborough life boats have always been white below the waterline. The crew are star war figures modified with plastic putty and a sharp knife. Not an easy build but very enjoyable. Eric Plaxton was the chairman of plaxtons coaches, and platoons building services. He left 9 million pounds to the boro of Scarborough, and 3 million to scarborough R.N.L.I., for a new boat .
Many thanks , Yes I like the colour scheme as well. I have several projects I would like to start one being the jet drive boat. as I already have the jet drives in the drawer for the last 12 months,regards Jim clark
Lady Wooes, by Mobile Marine of Lincoln. SemI kit. I bought the hull all the timber and drawings along with dozens of white metal fittings ages ago, started it and left it for 5 years, moved to North wales and finished it. Drive is 2 Ford Cortina fan heater motors driving a pair of 55mm Prop Shop props by tank steering, reciprocating steam engine sound board, smoke unit and full working lights all from 2 X 12 v 7 Amp batteries........a good and interesting but very frustrating build to get things right.
Sailed at Erias Park, Colwyn Bay Model Boat Club and sometimes at West Shore LLandudno.
Mantua models 'Amalfi' Scale 1:35 Length 400mm. Fishing boat converted to 2 CH RC. Sails well, freeboard a little low but ok. Nets detactable for heavier weather sailing!
Photos show her on home 12' dia. pool but she sails well on boating pond. Runs for 20mins. on 4xAA batteries all in.
Yes the gear noise is a problem, tried to fill the gear box area with some light grease but not a good solution ..messy and too restrictive.
Going to only run the radar when under way, switching radar on via a mercury switch and the forward momentum. Noise not a problem that way and it won't wear out as quickly.
