Richard,

What motor/battery/speed controller set-up do you have in your PT?

Hi Russ

Mtronics Vision 600 motor

Overlander 50amp speed controller 50amp Forwards & Reverse. (20Amp reverse) with a 20 amp fuse [No set up just plug in and go]

9.6v 4300mah racing pack battery from http://www.component-shop.co.uk/html/batteries.html  [very good price]

Goes like the clappers. Only use half throttle to plane at scale speed.
Get about 30mins continuous running but dont often do that as motor gets a little warm, so have a few breaks. O0

Have just changed the motor to a Deans Marine Kestrel 5, 5 pole motor running on 9.6 V as the Mtronics Vision 600 was too powerful and was running too hot and noisy.
The Kestrel has slightly less power but it only gets warm and you cant hear it running. Still gets on the plane alright and doesn't need suppressing.

Trouble was Jay, that with the vision 600 it wasn't in the water much, it was airborne and hot.

Have you thought of water cooling the motor (should look at the build thread more closely)

Then again with a slower motor it will last longer on the water  O0

Got a water cooling coil on the bench Jay. I am going to use it with the vision600 motor in my 1970's cabin cruiser.
