- Dave MVice AdmiralHi and welcome to the site.
If you are considering using an IC in the model I suggest you find a local club or water where you can sail. Many local authority waters prohibit IC engines.
I see you recently asked for details of a club in Torquay and note that we do have a club registered (Model Boat Clubs) as Torbay and District MBC. You could try sending a pm to one of the members registered as sailing there and ask for details.
Good looking crew!

- RNinMunichFleet AdmiralHi Ned, Welcome aboard 👍
On my Sea Scout (little brother of the Sea Queen) I used silicon sealant (a la bathroom!) and a small brass screw in each corner. it had to be good cos I had the RX, RX battery and rudder servo tucked in there!
My boat was also started by Dad in the sixties. He had it free running with a Taycol Target and wet (very!) 6V lead acid cells. I upgraded to RC and Decaperm motor about 25 years ago and am currently restoring and converting to brushless 😲
Happy boating, Cheers Doug 😎Liked by Brucef102
- jenteckRecruitVery nice model was it a kit or scratch built thank again
excellent video alsoLiked by CraigRobotham - CraigRobothamPetty Officer 1st ClassThese are originally an I.C kit 1/6 scale , there is a company in Germany still making them believe they are called MHZ. I think I've scene them in 1/8 and 1/35 scale too . Also other builders have used water jet drives on films I've watched . This one is running on brushless motor normal prop and direct drive as all my boats have so far . Keeps the cost of spare parts down %uD83D%uDE0E%uD83D%uDC4D
- sharpy1071Chief Petty Officer 2nd ClassThank you figtree7nights, up for sale now!! it's stupid on 4 cells, mad on three but behaves very well on two. I sail it mainly on three cells as I have more 3 than anything else.
Your new motor seems to be a larger diameter 58mm?, as opposed to 31mm for the old one, so I begin to wonder if the old ones were simply overloaded by a big prop causing them to draw more and more current and hence cook! 😡😭
Check out this test drive (Italian)of your new type motor!!
cheers Doug 😎
PS Caption says that with more than 3/4 throttle the boat becomes unstable! Then it flips 🤔
True the spec says 12.6v and 35A, which theoretically gives 441W.
And the power is rated at 220W. This simply indicates to me that the motor scoffs 441W of power (at Max ratings) and spits 220W out again, i.e. ~50% efficiency 🤔
Almost any decent brushed motor will beat that! But with other penalties😉
Cheers Doug 😎
