Only too happy I could be of some use, wish I could have made it on Sunday but it looked a bit rough in the latest photos anyway! Thanks for all your support and kind words over the last few weeks, take care and I'll hopefully see you soon, Dave.

They should send you a freebie, would be great promotion for them too. Hope you're doing ok? Hear Alan's got computer trouble, bl##dy modern technology for you... Looking forward to the Southern Model Airshow, long time to go yet though, Dave.

evening all

not long got back from alan's. we spent some time taking out the 850's and putting in some brushless motors.
gone from 140 watt motors to 1500 watt motors. i don't think it will be underpowered any more.

going down the lake during the week sometime to test will vid and post.

will have to take the water ski's

phil

Spec's please

I highly doubt that they will pull 1500 watts though

Cheers
Nick

hope not when alan reads this he will post the name of the motors i am sure

Hi everyone out there in Mayhemland,i have been building up the brushless set up for the type 45.
I am having a test day at Mote Park Maidstone on Sunday.
The motors i am using are E Max BL4030/10, KV385 ,1500w.
The ESC are 80A HV Seaking
I am runing on 24volt.
I am going to continue using the 4.2:1 reduction.
So motor speed @ 24volt =9240 rpm - 4.2:1 reduction =2200 prop speed.
I have around 500 rpm more than i need,but it is nice to have abit in reserve.
I am fitting it own self contained water cooling system using modern car coolant.
I feel put lake water through pricey ESC is not a good move.
Well here are some picture
regards
Alan

Lake water wont affect the ESC's , the cooler is a separate aluminium block, in fact I doubt it will need any cooling . It does add to the cool factor though, Like Toesup's MHT with the working keel coolers.

Look forward to seeing the test results

Cheers
Nick

Alan .....I agree that lake/pond/sea water pumped through miniature electronic speed controller RAW aluminium heat exchanger is not a good plan

, however pumping automotive ethylene glycol through a keel cooler & back to the speed controller aluminium heat exchanger is a brilliant fix

....good luck...it will work

looking at the state of the water in our lake i wouldn't want any of it in my boat

just as likely to block any water intake

Southport's is a bit crusty at the moment

Hi everyone,I have now fitted brushless motors into my Type 45.
The cooling system is in and working fine.
The water pump has it own ESC.
So the faster the motors turn,the faster the water is pumped around
I am looking forwards to trying it out on Sunday.
I should be at Mote park from around 11am.
so if you are around Maidstone sunday come and see her go.
I will take some video,and put it on Sunday night.
Here are some pictures of the set up.

Hi everyone, especially you Alan,

Well I thought that I would have a look and see how the boat is coming on.

The boat is coming along great but there is one thing.
What is my new tupperware box doiing inside your boat.
You are in trouble BIG trouble.

No dinner for you tonight!!!

Think I might have to go throught the rest of these pictures to see what other
bits and pieces belong to me.

I wonder how many more of you use boxes etc.. that were in the kitchen cupboard and
are now part of your boats. Wives/partners beware.

Well have a good day everyone.

take care
Debs xx

Hi everyone, just up from the workshop.
Three sets of battery charged up.
11 Foot box made for the stern section.
Ship tested and working ok.
So of to the lake in the morning.
I will post the results Sunday night.

regards
Alan

Lots of sucking to the wife over knicking her tupperware container

whta a really interesting idea using a contained cooling system! I love "new" ideas

, nevere heard of this before, keep us posted

AT Boatyard · « **Reply #122 on:** July 03, 2011, 10:43:51 pm »

Hi everyone,well got down the lake at 11am.
Had the boat in the water by 11.45am.
Over the moon with the performance.
Got to make some new and better coupling,as we blew the couling with the power of the motors.
As for the motors and ESC,s not even geting warm.
We had it runing for over 1hour before the couling blew up.
Here are some picture and video

That's a big improvement over the brushed motors

Have you made any comparison of the amp draw between the 2 set-ups. What sort of coupling was it that blew? I couldn't see a pic of it?

Did you happen to check the coolant temp after the run.

Cheers
Nick
