Chaps,fellow boaters, countrymen..

Having removerd the electric motors form the RTR Severn, in preparation for proper remote control, it struck me that the units are not, or dont seem to be, sealed against water, and that they could be used as seperate thrusters for, say , a QM2 model, or similar. More to the point, I wonder if you could not simply encapsulate a small electric motor in, for instance, resin, and use a push-on prop, and have an instant thrust unit. The RTR ones dont seem to suffer from being soaked, and indeed I believe electric race types used to run-in thier motors underwater (no idea why??).

It seems a shame to spoil a QM2 working model by using ordinary shafts when a solution may be at hand??????     Ashley

Paul. Interesting. I will file this idea away for future consideration…    Ashley

Paul. I have perused at length. A 600 motor is a fair size to have a under a boat, your pod must have been a whopper! It strikes me that it would be relatively easy at that size to make a bevel drive system, using some easily and cheaply available gears to do the same thing.  The motor coud be fixed with a bevel drive system, with either a bevel at the top or simply having the motor face downwards over the pod swivel, driving the downwards shaft directly…  If short lengths of brass prop-shaft tubes were used as the downwards drive and the horizontal moto drive, then they could be soldered together with plate to hold the bevel gears in engagement, and then a casing of suitable size and style for the boat could be built up around the cogs… avoiding water sealing probs at the bottom end (water lubrication)      Ashley
