Mine is MTB741. it is powered by 2 Graupner Speed 700 12V motors with NiMH batteries. The 6 pdrs and 20mm guns can rotate. it has a balsa planked hull and fibreglass skin. Decks and superstructure are also balsa. Guns are from tinplate and brass.
- RNinMunichFleet AdmiralVery impressive 👍 well done both.
Great looking location as well.😎Liked by reilly4
- RNinMunichFleet AdmiralHi, thanks for the info👍 I'm new to BLs, but learning fast, and your experience confirms my growing suspicions that outrunners not only deliver more torque than inrunners (size for size) but that they are also more reliable and seldom need water cooling.
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 🤔 - RNinMunichFleet AdmiralPS Don't worry about 'adding up' the Watts and Amps!
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 😎
- Novagsi0Chief Petty Officer 1st ClassThat video was from 9 years ago and that was the camera on the latest phone for the time. Since power boats are banned at our pool this is the only video i have of the model running, sorry.
Posted for posterity. MY other boat 26cc kawasaki engine was same time pre IC's ban.
New homemade carb and also tried running on glow fuel and a glow plug, instead of petrol and the electronic ignition.
Not used any more IC engine's banned at our POOL.😱
- manyboatsPetty Officer 1st ClassTrying to reply to your query about Huntsman power plant, cant find the right place.... anyway cant give you a sensible answer as I dont know. it's an old brushed motor given to me. Will operate up to 24 volts and I'm running it on 14. I think its just right.
Cheers
the deck fittings were copied as best as I could from photos and drawings found on line. powered by 2- 2200kv brushless out runner motors through 2 20 amp speed controllers. twin contra rotating props twin rudders fast and light a pleasure to build

I hope this helps if not let me know & I will take more pictures
i was able to put a high deck in because of the size of the hull
it might be difficult to do this with the smaller hull take a look on SLEC they do the River Police Launch (last picture)it appears to to be risen at the front to take the motor etc
The Vintage Model Boat range are now being produced by SLEC Ltd. All our kits come with all parts cut by CNC router or laser, plus all the necesary strip wood is included, along with building instructions and plan.
The River Police Launch has been based on the old Veron Kit from the 1960's that we all loved at that time. The model is not a scale model but embraces the boat design of that era. The kit is now fully laser cut so all parts are pre-cut and most of the parts are now made out of high quality ply, so obtaining a good finish is easier to achieve. The model can be powered by a 7.2 volts standard buggy battery pack or ic power of .5-1.5 cc engines which is not in the kit, also we have not included any running fittings as we feel a lot of modellers will have or would like to choose for themselves, but we can supply these fittings if required.
- KrampusWarrant OfficerBy the way, you may get some Viagra (10.8v Nihm battery) on Ebay. You will find them with either AA-type cells and C-type cells. I do prefer the C-type cells. Expect to pay around $45-50 USD. I bought some from a German store named "www.Conrad.de", but it seems they no longer offer them.
I will contact SHG they stock a few sizes
Love the detailing, and on such a mammoth scale as well!
Popsicle sticks! You must have made a lot of children very happy👍😉
I've heard of others getting all family and friends to 'collect' coffee stirring sticks ...
Next model with zig million matchsticks perhaps ? 😉
Shame we will never see her under way but a superb memorial to her and her crews. Cheers Doug 😎
