Spray paints by Westquay Fleet Admiral!   Posted: 4 days ago
If they are enamels like Plastikote used to be, yes, but as far as I know, Plastikote changed formulae to acrylic, which, if their brush pots were anything to go by are complete crap. I had one that reacted with itself! I complained bitterly to them and they sent me every pot of enamel they had left in the office! Martin

Bluebird by Biscuit Sub-Lieutenant   Posted: 5 days ago
[Score: 10/10] 27" Bluebird Single Propellor (2 Blade X Type) Direct Drive to a 2881kv (2 Blade X Type) Powered by LiPoly (11.1v) 4Amp/h Batteries Controlled Through ETTI (120Amps) ESC - Comments: This was a Touchwood static kit that my boy brought back from Coniston, it said it could be converted to Rc and had some sketchy drawings that were not very good. I decided to go brushless with it and lipo battery, was not an easy job as had to go it alone to find out C/G and drive set up. The kit was very poor with a twisted hull and resin parts that were far too heavy, I made some aluminium planing wedges and various other parts to save weight. This project took the best part of 5 years to complete as it would go back on the shelf as I got stumped for ideas then back off again as I found a bit more inspiration, overal it came out well and runs on rails with. Good turn of speed as you can see in the vid I posted.

BRAVE BORDERER - BRUSHLESS SUMMARY by jbkiwi Sub-Lieutenant   Posted: 6 days ago
The only thing you might have to watch out for is back feed from the pump out the aux tube (when moving) if you don't set up the y joints (must be y not T ) to create a venturi effect from the pump side. Doesn't matter standing still but at speed a T junction might reduce the flow as the flows will be fighting each other slightly. The beauty of the twin system is that if you are running a lot at high speed you could turn the pump off to save power. The best place to position water intakes is I have found is directly behind the prop (I usually just squash the brass tube slightly, fair it, cut it off at 45 deg and set it to just sit in the prop wash). At lower speeds especially, the prop will help to push water into the tubes rather than just relying on speed alone. Never had a problem with pickups interfering with rudder effectiveness as long as you fair the pickups nicely

Tearinto Jet boat by Biscuit Sub-Lieutenant   Posted: 6 days ago

Never thought of using separate feeds, good idea. That pump looks like the one I used too.

Vosper by Biscuit Sub-Lieutenant   Posted: 6 days ago
[Score: 10/10] 42" Vosper Single Propellor (3 Blade 50mm) Geared to a Os 40 fourstroke (3 Blade) - Comments: I always liked the sound of a fourstroke engine so I thought I would replace the brushless motor in this boat with an aircraft Os 40fs which I converted with a water cooling jacket that I turned up on my lathe. I also made a reverse gearbox with a clutch, the gearbox is operated by a servo and works well, I also fitted a water pump so could still cool the engine while ticking over stationary, boat has been weathered and is fitted with lights and a searchlight that swivels around operated by another servo, there is also a cooling fan above the engine just to help keep things cool.

Fast electric rc transmitters by boaty Admiral   Posted: 6 days ago
Just got a new Proboat Sonicwake .The e.s.c and brushless motor look very good but the STX2 TX appears to be a bit cheap . Not sailed it as yet but changed over to the Futaba T2HR system as I had already done on my Blackjack 29. I prefer the stick to the wheel and the Blackjack runs very well on the Futaba T2HR and has the steering adjuster on top right of the TX case. Has anyone else used the Futaba set in place of the one that comes with the boat.😁 Boaty

Great idea using separate feeds.One less worry.👍

BRAVE BORDERER - BRUSHLESS SUMMARY by jbkiwi Sub-Lieutenant   Posted: 6 days ago
I used this pump from E Bay which pumps well, and with the rubber mounts is quiet. 6-12v (I use a 2 cell LiPo which seems perfect) and am cooling 2 2000kv 28mm in-runners. Have tried a few different pumps and these have been the best so far. You have to be careful that you don't over pressurize your plumbing system, as if the hoses come off while running you can fill your boat up in no time. It's safest to adjust your pump voltage or piping to a 'neutral' pressure rather than risk hosing down your electrics. I used twin pick-ups behind the props and separate feeds, one for the pump and one direct in case the pump stopped or blocked.

Ashes the scratch built Motor Torpedo Boat by Sakibian Chief Petty Officer   Posted: 7 days ago
I found this hull at thingiverse last year. I printed the hull from a local shop and rest was handmade. Firstly I bought a 2426 4200kv brushless 2-3s which was too powerful and too heavy for the boat size. The length is 38cm. And the 30Amp esc was also too big for it's size. After that I tried small 180 brushed motor with 20A brushed esc w/brake. It was perfect (still it's heavy😂). The bridge and deck is made by 1.75mm pvc,torpedos are made of wooden pencil. Small battery space takes a 2s 500mah lipo. 30mm 3blade propeller. YouTube video link is here: https://youtu.be/KZdmZ8_Z0IE

Thank you! Found this pump in Ali express. Here's the link if anyone needs: Waterproof Ultra-quiet Water Pump 4.2W 240L/H Micro Brushless DC 12V Water Pump Car Submersible Fountain Aquarium Circulating https://s.click.aliexpress.com/e/cVs7aajO

Well this started off brushless but it had no soul or character, I bought an Os 40 fourstroke and converted it to be water cooled, I then made my own reverse gearbox and clutch assembly and fitted a water pump so the engine will keep cool while stationary. It has nav lights and a working searchlight that I can move while running.

Used a small 6 - 12 volt pump bought from E Bay. Have used windscreen washer pumps before, but they are relatively heavy and bulky. This was quite compact and light and were closer to my weight restriction.

BRAVE BORDERER - BRUSHLESS SUMMARY by RHBaker Fleet Admiral!   Posted: 7 days ago
The pump was installed to give positive water flow even when stationary. Felt this would ensure cooling under most conditions. The plumbing is quite torturous and suspected there might be a significant head drop in the circuit. With the wisdom of hindsight, probably overkill; the water scoop between propellers may prove adequate.

Is it a car windscreen washer pump ?
