On the roof of the wheelhouse there is the radar. For this model I took a look at the Smit Bronco which has a stabil construction for the two radars. On the Arca there will be one radar and one sat communication.

As a base I used een tube construction with 6 mm tubes.

the support beam is ready to be soldered.

basis 3

Soldering is done with the small torch.

basis 4

The support beam is made on the right lenght and a verticale tube is added.

After this was ready the question was : where to place the radar motor? I use a small motor with a transmission mounted to it.
