Waterproof servo connection?
« on: July 22, 2017, 05:45:14 pm »

Hi,
I am building a Robbe U47 and would like to control the front planes using a waterproofed servo (underneath the conning tower probably). The servo will be in the flooded front section and will need to be connected to the receiver which is obviously in the wtc. Since the two parts of the boat separate I will need to be able to make and break the connection in the servo wire - (this connection will be in the flooded area) Does this connection need to be waterproofed or am I worrying about nothing?

Hi Keith,

In the absence of any other replies to this one. Some links here may give you some ideas:

(I still feel that putting servos outside a WTC is best avoided,)

You could try the automotive style connectors, They seem pretty well sealed and come in 3 pin varieties.

I don't think water conducts enough to upset a servo connection at only 5 volts or whatever it is but, corrosion of the pins could be the issue over time if you didn't use a waterproof connector.

Hi,
Thanks for the replies. Perhaps I should rely on the rear planes for control.
Thanks again for your interest.

If not too late I put mine inside the watertight area. I used a slimmer servo and by also using a slim servo for the rudder mounted the pair where just the rudder servo had been. The linkage for the front planes exits where the on/ off linkage went ( I made magnetic switch to replace). This goes to a large pivot lever, a rod( running in a tube) leads forward under the deck but can be disconnected or the aft point to allow the sub to be split. Another crank at the front the same size at the rear takes this movement down to the front dive planes. You may think this is complicated but it was very simple to install and is very low friction. I can email pictures if required
