The boat went out lots of times whilst being built.
The boat went well, quite fast and very stable.
The battery lasted 20 minutes and the cooling system worked fine.

I made some simple exhaust from some pipe and got some cleets.
All I need now is some flashing lights and police stickers.

Being a long time since the last update. I now have some very good looking POLICE and 442 stickers.
Also fitted 2 searchlights to the cabin roof one facing forward and one facing backwards.
To finish the fittings of I went for a set of bollards.

Sorry mate, Your cabin roof light should be Blue and not red. All Marine Police vessels and Coast Guard use a Blue Light. if you used Red it would be confused with Navigation Marker Bouys. By the way your boat looks good from hear. Keep up the good work. Cheers.
Here are some photos from the last time it went out.
Running a 3600 racing pack is was fast, but not as fast as my seaplane tender so I am going brushless............

The brushless ESC is now in, its un branded but is rated for 50 amps and up to 22V so should easily be able to handle the motor. I connected it up to the motor and it works ok just a little cogging at low speed because the motor is sensoreless.
The motor is a Turingy 3600 KV inrunner with a built in cooling coil, I found out after ordering it that out runners have more torque and stay cooler. (should have done more research). I'll give it a run with different sized props and voltages, then change to an outrunner if there are problems.

The rest of the parts arrived and the motor is now in.
Tested it in the bath and the power was incredible, easily twice the power of the graupner 600, next is a test on the lake.
I also brought a 7.4V 4000mah LIPO pack for my car so while I'm at it I'll see what it can make the boat do.

With the boat weighing a lot less it was a lot faster. Although over half the boat was out of the water it planed fairly level but was very difficult to drive.
And after a few minutes of driving with LIPO the tamiya connector's melted, so I will be changing to deans connectors.
Next time the boat goes out I will get some video.

I swapped the tamiya connectors for deans connectors now I can go flat out without worrying about melting anything.
Also added a cooling fan to the ESC to keep It cooler.
Didnt want to try and water cool It Incase of a leak which would be a disaster with the LiPo In.
To keep the LiPo safer I have fitted windows to the back cabin, I will get some photos......
