Looks very well Phil. Hope you had a good day.
The motors in the Tamar are Tornado C5065's.
On the label it says :
1400Watts Max
80A ESC
3-9 Lipo.
Choosing the Speed controllers was difficult because wow, are they expensive!
Considering the 80A requirement on the motor, I have gone for a Barracuda-80 from Castle Creations in the USA.
It has a resistance of 0.0006 Ohms so should run very cool, even with 80 Amps at 24Volts going throught it. It won't actually ever get near that because I will fuse it at 40Amps too to be sure. With the motors only good for 1400 Watts at 24Volts that means max Amps of less than 60. I just cant see a model of this weight ever getting close so I am pretty confident with the plan.
Not too suprisingly, we lost two props messing about. (The new ones are tapped through with lock-nuts both sides to be sure). A rudder came loose on the shaft and I found that with the bow thruster on the left stick it was too easy to run the thruster when well out of the water. Practice I guess!
Having just read the instructions for programming the speed controller, I'm thinking of taking up gliding.......
The fittings for the Tamar are done now thank goodness, what a game?. I thought the Tamar would be a piece of cake after the Severns. WRONG! All new, pin sharp resin castings, no metal ones at all and some very natty constructions with mind blowing detail built in. A few bits coming out of it too for general sale: scale section fendering (still waiting for that though) and scale 2 ball stanchions in turned brass.
