Getting some go

drive shaft

After all the messing around with paint, filler and varnish I can get on with fitting the hardware to make it go.

The instructions make it seem pretty simple. Use a dismantled servo to turn the propeller and a normal servo for left and right. The drive shaft comes pre-assembled. It’s a brass rod stuck on a bolt. Neat and effective although not something that the scale modeller would appreciate. I wondered about it myself but decided to go ahead as the homespun look fitted the boat I was building.

To couple the motor to the shaft a rubber tube is employed. This has worked well in other boats of this size so I’m not going to buy a proper device for this, not least because it would cost about the same as I paid for the kit !

A blob of Blu-tack held the shaft in place and I squeezed glue around the motor, which was in sort of the right place. When this had dried I filled the hole the shaft runs though with “Liquid Nails” glue to fix and waterproof.

The exciting bit of the build approaches- once the rudder is in I can try it on the water.
