A collection of plans for the classic wooden boats plans- the models vary in size but I prefer to work on models that are about 1m in length or larger so the majority of plans here are for the larger models. I have also included a section on RC Hardware with Wiring Diagrams for basic RC Boat and Ship layouts.
Set paper size in the print options in the Adobe print menu - ensure paper size setting is correct. The plans are large sheets 2A0 in sheet size - the large sheets that are best printed at a print shop such as Kinko's or similar high street printers.
Each type of motor used with the Radio Control gear requires a specific design of Speed Controller.
The Speed Controllers above have a water cooled Heat Sink to prevent the RC Speed Controller overheating. You will notice that the Brushless Speed Controllers and Brushless Motors have three wires to supply the power to the motor. The Brushed Speed Controller and Motor use the conventional Plus and Minus leads to run the motor and the electronic speed controlled basically switches the power on and off at a high speed to control the power to the motor.
The design of Brushless motors allows a Water Jacket type of heat sink to be used to remove the heat from the electric motor while under load. The water is fed from forward facing inlet on the hull which forces the water into the jacket and out through a drain - this is the most efficient way to cool you RC Boat motor.
The Battery Connection, Power Switch, Radio Receiver and Rudder Servo connection are also shown on the RC Ship Wiring Diagrams - Click on the thumbnails to download the full sized wiring diagrams.
For those out there looking to purchase a 52cc engine most vendors list them as 49cc motors due to liscencing restrictions for scooter use.
The best direct source for the 52cc motor is Monster Scooter or Scooter Parts 4 Less, eBay is also a good source. I have just started on the 52cc motors, Mark Wollner and John O'Neal are your best source for more information on them. I ordered a 52cc from Monster Scooter late (after close of business) yesterday and it has already shipped, so that I am happy with.

Location: Minnesota Couple of pics of the boat and motor Took out the motor for its first real hunt.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. I thought at one time the whole kit could be purchased for around $400 including the engine but that shipping to the States made this rather expensive.
Location: Thailand If you purchase the kit, there is no additional cost for the engine base and transom mount but the shipping costs do make a big jump.
Location: Portland Well guys I finally got around to starting on my conversion.
The ryobi shaft I cut in half and then used a smaller shaft I had from a mac weed eater to go inside the ryobi shaft and also used the end piece from the mac.
I took out the pieces from weedeater assembly on the mac shaft which was a sqaure adapter and the shaft which screwed into the hub. I then used a drive shaft same as used on rc boats & a ferrule that connects the flex shaft and the drive shaft together. Then there is a drive dog on the end of the drive shaft that connects and holds the prop in place with a set screw and the prop is held on with a zuber nut.

The speed controller converts the DC battery power into a kind of 3 phase AC voltage to run the motor. Duropower doesn't plan on selling the 52cc anymore because of a lack of sales, and they don't even have the trimmer listed on their site anymore.
Did you make a jig, that was my first thought, but if you have an easier method, I am all ears.

I really want to try the 5:1 reduction gear box on the smaller 33cc motor to see if the motor has the torque to push it, I know there is less than $25 difference in the motors, but it may be worth a look see, if nothing else, it gives me another reason to go shopping.
I think the guy just blew you off rather than admit he had no idea how to answer your questions.
However for clone engines, in some cases the 4 bolts used to fix the coupler housing to the engine crankcase cover have to be changed to metric ones.
I think it is self explanatory if you refer back to my descriptions on page 47 and 48 of this thread.
I used a piece of brass tubing that I had which fit inside the 2 bearing which I then soldered on the next size up from that which will act as a thrust washer and helps keep the shaft from slipping in side the bearings while running. The flex shaft gets soldered to the ferrule then the drive shaft is heald in place by 2 set screws. After removing the governor, I came to the conclusion that the 15 degree rule of thumb does not apply to mud motors.
The cost is kept low so that everyone can have a chance to build the models - some lesser quality plans are for sale on the web for 10 times the price. Based on the available pictures it appears you will need 4 longer installation bolts plus the correct drive bolt which is offered on their site. Don`t give up you will hit the right guy (knowledgible) and he will fix you up.I think scooterpartsforless also has electric starters.
It appears that adding an electric starter because of its additional thickness requires a longer starter drive engagement bolt which is offered on the partsforscooters web page. This assembly also requires longer installation bolts(4) which should be available locally if they don`t come with the starter. Here is a pick of two of my builds the one on the right is a copy of an Iowa made motor using there prop design.
