Hi
A G60 brushless motor on 6S will give the boat great preformance.
1600 watts(about 2 HP @11250 rpm unloaded).

Hi Lads
After crawling the web, I finally found specs on crawler 540 motors on 7.2 volts unloaded.
20 turn 13000 rpm
27 turn 15000 rpm
35 turn 12500 rpm
45 turn 9500 rpm
55 turn 7700 rpm
65 turn 7000 rpm
80 turn 5500 rpm
The last three easily run 14-20 pound weight boats with 3-4 blade 50 to 60 mm props.
I am using the 55 and 65 turn in Helen fishing boats and the 80 turn in a tug boat.
No cooling on the motors !!

Hi Bill
A Hobbyking 3639-1100kv 800Watt on a 3S 5800mah Lipo battery with a 100Amp ESC and for a prop 2 blade 40-45mm.
If you require a faster motor a 3648-1450kv is a straight change over with all the other bits the same.
Also you can change the battery to 4S and it will be a rocket.

Hi justkiddin
I live in Hobart, so not to far away from you mate.
My mate and I both have Sea Hornets, his has a funny cabin on it also.
Mine is build by the original plans.
Brushless 28mm 1900kv, 45Amp ESC on 3S with a 32mm prop.
Was GPS at Lauderdale canal at 45KPH.
WE sail on a Saturday morning from 9 to 12, so if you are down this way call in.

Hi Stuart
I think Dave Milborne used a 1000 or 1200kv 28mm brushless.
You can PM on the model boat forum site.
He is the kingpin on Huntsman's and is Fairley helpful guy .

The hull looks to be an Aerokits Sea Hornet with a difference top.
The transom looks the right shape.
The Sea Hornet was 25 and 1/2 inches long.

Hi Guys
If you use the 3639-1100kv(800 Watts), you can straight change over to a 3648-1450kv(1600 Watts).
So starting with the 1100kv
3s=12,210 rpm
4S=16,280 rpm
The 1450kv
3S=16,095 rpm
4S= 21,460rpm
Only double the power and 5,000 rpm more!!!!
And the 1450kv can handle 6S, if you are brave !!!!!

Hi Bengtt
For that size model I use a Hobbyking 3639-1100kv brushless motor or a D3548/4 1100kv on a 3S lipo battery(between 3700-5800mah), a 60 or 100Amp car ESC (HK-60A-SL or HK-100A), program card(HK PROG-CARD).
I have a good setup for this system, if you require.
Prop start with the one you have, but I use a 2 blade 40mm or 3 Blade 37mm (brass or CNC).
Slightly over scale speed, depending on the boat.

Hi
I use 10mm magnets in a double setup, one mounted on the hull and one on the cabin on each corner of the cabin.
On my last Perkasa I used the double setup forward and a single double setup on the stern.
The total weight of the boat is six pounds and I can lift the boat by the cabin!!!

Hi All
The boat had the rudder completely vertical to start with and that is the problem.
With the rudder vertical the boat pulls the bow down in the turns which makes it sit up on the chine.
A planning hull attack angle is about four degrees to the water, but these boats like an angle of about six degrees.
The leading edge of the rudder and the angle of it governs bow lift or dip in the turns.
Also the balance point of the boat is as important as the rudder setup.

Hi
A few pics of my modify setup, no pics before hand.
Moving weight fore or adding ballast works better than wedges.
Only tested the boat by myself and I gave it a real workout.
Motor 3639-1100kv, 60A ESC, 5800mah Lipo and 37mm 3blade prop.
A 40mm 2blade works better and uses a bit less power.
Rudder blade size 30mm across the top, 22mm across the bottom, 45 deep and the shaft 10mm from the leading edge.
Sharpen the leading edge and the trialing edge flat.
This catches are air in the water and send it to the surface.

Hi All
I use silicon tap grease as it's waterproof and add a bit more after each outing.
Strip down, check for wear once a year and regrease.
Started using Teflon bearings for the lower bearing which are holding up to the brushless motors.

Hi All
If you require a brush ESC.
The Hobbyking one is the only one I have found with straight forward/ reverse with NO BRAKE.
Set is with links, but the they only work on Nicads and Lipo batteries.
They will run on 12 volt SLA, but no less!!!!
I am using them in my two Hellen fishing boats with 55 turn rock crawler motors on 2S Lipo on 60% throttle.

Hi All
I use the Hobbyking car ESC's HK-45A, HK-60A SL and HK-100A
which all use the same program card(HK PROG-CARD).
I use the same setup for all my boat, only changing the battery setting for the 2s, 3S and 4S Lipo.
1 Cutoff Voltage for 3S=10.2 and 4S=13.6
2 Start Power Percent=5%
3 Advance Timing=4
4 Run Mode=2
5 Brake Force=1
6 Drag Brake Force=1
7 Neutral Range=1
8 initial Brake Force=1
9 Reverse Force=1
It works for me.

Hi RHBaker
I had the motor ,so I used it.
The sister motor is a 3639-750kv 600Watts 8325 rpm on 3S.
The 3639-1100kv 800Watts 12210 rpm on 3S.
Next up the 3648-1450kv 1600Watts 16095 rpm on 3S.
All are straight bolt replacement, but, the 3648 requires a 100Amp ESC.
The 3639 750kv would be the better motor for the boat to get scale speed.

Cracking on with the wheelhouse and playing with the LED lights.
I drop the wheelhouse lights from 4.5 to 3 volts which made them look a bit more yellowish.

Hi Sandgrounder
There are a number of speed 400's with voltage range from 4.8 to 7.2 volts.
The revs range is between 16,400 to 22,000 rpm.
So 28mm brushless like a Prop Drive V2 2836- 1800kv(shaft 3.175mm) on a 3S Lipo battery with give you 19,980 rpm.
ESC 45Amp.
Prop 30-32mm 2 blade.
If it's tight of battery space Hobbyking have small ones you can parallel together like the Turnigy 3S 1500mah 25C (73 x 33 x 27 mm).

Installed the deck and filled around the edges.
Gave the hull a quick run and it handle very well.
Good turning circle and at 50% throttle still over scale speed.
3/4 throttle looks about right.
