Graupner ranzow refitting by kmbcsecretary Captain   Posted: 19 days ago
Here we have the working crane for lifting the buoy's into/out of the water. Again this was converted to working by using three micro motors rated at 300-1 plus one gear box at 5-1 to operate the rotation and a 4-1 gear box to operate the lift and lower first pic shows the crane completed second pic shows the line winch motor which is just a 300-1 micro motor. third pic shows the lift and lower arm with the motor and gear box is hidden in the crane body fourth pic shows the micro motor and gear box that controls the rotation, there is a similar layout that controls the lifting arm the final pic shows the micro speed controllers that you can do the fine control of setting the required speed that you want.

Graupner ranzow refitting by kmbcsecretary Captain   Posted: 19 days ago
Here we have the working radar and search light . The radar was easily converted to working by using a micro geared motor rated at 300-1 controlled by a micro speed controller thanks to mr rc world electrics. The original radar mould was first filed flat underneath then a small hole was drilled and a brass rod was glued into the hole with about 5mm sticking out and this was attached to the micro motor using some heat shrink. The second pic shows the micro motor hidden in the bracket

Graupner ranzow refitting by kmbcsecretary Captain   Posted: 21 days ago
I originally built this about 6 years ago when I was still a novice builder and some mistakes were made and it ended up partially sinking , it was left in the workshop for about a year before I decided to refit it out. The deck just lifted of the framing without any problems because it was rotten as well as some of the framing , the motors and prop shafts had seized and most of the electrics and the battery had shorterd and corroded due to the sinking. I had been doing the odd bits of the refit over the past couple of years not really in any rush to complete it. After replacing the rotten framing I started to replace the electrics with all new gear Battery 12v 7mah Motors Mtronic 560 Working crane using 3 mini motors with Mr RC world micro speed controllers Working anchor winch (krick I think) Full lighting kit and working radar Main speed controllers electronize The pictures shows as it is now ready for the new decking to be fitted

Vintage Aero Kit Crash Tender by CB90 Commander   Posted: 1 month ago
Brought this vintage Aero Kits RAF Crash Tender for £50 from Newcastle area, it is the 34in version. To my surprise at home I found that it had a Bullet 30 motor installed these motors were the top drawer motor of early fast electrics and its the only one I've ever seen, it can run on 24v and pull around 15A giving 300w not bad for a brushed motor. due to the power of this motor I have modified the hull under the water line with turn fins and trim tabs to reduce torque roll and improve turning stability, the underside is incorrect already as it only has one propshaft, where the original had two and I believe that both props turned in the same direction. The Pictures here show some of the work in progress I have remounted the motor and added a speed controller rated at 24v I have remade the stern compartment and rudder gear under it. I have blocked windows and foamed the front half of the boat. made missing parts and repaired delaminating ply. Note old ply is not as good as modern, the glue is not as water resistant. Have painted the hull and have just ordered the decals from Cornwall model Boats :-https://www.cornwallmodelboats.co.uk/cgi-bin/sh000001.pl?WD=... The 34in is 1/16 scale Fitting can be brought but many are cast white metal and can add weight to the boat, I have made two water cannons and plan to buy plastic fittings from this site. This has turned out to be a task that is difficult to assess how much effort and money to spend on a hull that has been built by someone else (say no more). Have just finished the steps for the stern compartment.

PT 109 by CB90 Commander   Posted: 1 month ago
[Score: 7/10] 40"/3000g PT 109 Capable of 9mph and a runtime of 30mins Twin Propellors (3 Blade 35mm) Direct Drive to a Graupner 600s (3 Blade) Powered by NiCad (7.2v) 4Amp/h Batteries Controlled Through 2x Aquapower (30Amps) ESC - Comments: PT 109 The famous ww2 PT boat skippered by JF Kennedy (later to be President of the USA) This has be one of my have to have model boats and it was by luck that I found one for sale on a model boat club's web site in 2013, £100.00 later and a journey from Cumbria to Yorkshire and back, I had myself a ProBoat PT 109 This was a ready made RTR model when new and is 40in (1m) long, the boat needed some small repairs but after a test run I found that the running gear was noisy and on investigation discovered that both propshaft were bent and had no bearings from new, the couplings were just direct connections. So with great care I replaced both prop-shafts, propellers, coupling for two double Huco's (universal) and the single ESC by two new Aqua speed controllers and both motors with Graupner speed 600's Note I also foamed the front compartments to make it unsinkable in theroy.

Up Grade NDQ speed boat by CB90 Commander   Posted: 1 month ago
This is not a build but a modification of a cheap Chinese boat just for fun, I got a bit bored of scratch building projects as they take so long especially as I am not retired yet. The NDQ 757 Coastal Brother 1:25 Radio Controlled Racing Power Boat cost about £25 from Amazon. These boats have a basic 27mhz radio and two 380 type motors which have forward and reverse and you steer by powering one motor or both for straight ahead. I bought two of these boats as they are light and about 24 in long, one to convert/upgrade radio, esc and brushed motors the second was to upgrade radio, esc for brushless motors. The brushed motor version I put in two higher rated motors (390) with cooling fans built in, but same motor diameter but longer body I had to modify the mounts, kept same couplings and shaft/propellers. I did remove trim tabs (fixed) and replaced the straight running adjuster for a racing rudder. The brushless version is the same but has brushless motors 2x 2845 2600KV sensor less Specifications: KV(RPM/Volt): 2600KV RPM: 50000 Max Current: 42A The boat ran well but trimming needs attention, as hull is curved up at the back so trim tabs down, to prevent proposing, in-fact at one stage the boat left the water, but need to distribute weight towards the bow. Tried on 3S (11.1v) went well but got slightly warm not hot. checking with a watt meter after reducing the size of the propellers from 36mm to 32mm the current draw on 3s was about 20A in total approximately 120W per motor (total 240W

Aerokits Patrol Torpedo Boat by MouldBuilder Lieutenant   Posted: 1 month ago
Thanks Canabus. I have just checked out the transmitter/receiver sets. Very reasonably priced. I really do want to upgrade. The Turnigy is around £40 whilst the Flysky is around £34. Do you have a preference?😊 Would my Futaba servos still work or would I need to change these also. I know this might be a strange question, but as you can see from one of my pictures above, I have a servo operating the speed controller. How do you control an electronic speed controller with the radio. As for the battery, is the safety bag used to put the battery in for charging in case it catches fire? I am a little wary about using things that I may not have control over. I have been looking at brushless motors. Can you say a kv range I should be looking for to possibly increase the speed issue. You have mentioned 1100kv and others above but was just wondering what you would cosider to be sensible bearing in mind only one motor is practical witout major hull surgery. Can I assume that if a motor is given a kv rating that all motors are based on the same criteria, or are there other variables. Thanks. 👍

Aerokits Patrol Torpedo Boat by MouldBuilder Lieutenant   Posted: 1 month ago
Looks busy in there. I would like to consider a motor upgrade to brushless. This would require a new electronic speed controller. I assume this migt need a radio upgrade as well. I read above that the NiPo battery would be required for a brushless motor. Is this correct or is there a safer alternative. The pictures below show my current radio set up. I run on 27Mhz. Please also not that my Captain thanks you as he can now see ahead. Will post a picture of the gun when it arrives. I think it does not move though.😊

Aerokits Patrol Torpedo Boat by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Peter, Only those who don't know better laugh!😉 I suppose you mean ESC (Electronic Speed Controller)! What radio gear do you have? FYI: I still have an old (25 years) 40MHz set for my submarines, 2.4GHz don't like going under the wet stuff, it turns it's toes up, wrinkles it's nose and whizzes off into the sky 🤔 Also a pair of ancient 'standard' servos in the Type 1A U-Boat. See pic. I also have an even more ancient (35 years!) 35MHz set I'm going to use with my Catalina flying boat. They both still work great so why dump 'em? Look forward to the 20mm pic, I could use some, but ONLY if the guns are movable! Carry on Modelling, cheers Doug 😎

Percasa by andyhynes Chief Petty Officer   Posted: 2 months ago
[Score: 9/10] 49"/5100g Percasa Capable of 15mph and a runtime of 25mins Twin Propellors (4 Blade 55mm) Direct Drive to a 5055 580kv motor (4 Blade) Powered by LiPoly (11.1v) 5Amp/h Batteries Controlled Through Hawk Fusion 60 AMP (60Amps) ESC - Comments: This was a President kit brought about 6 years ago. This setup involved power 2 x 11.1 5000Ah 2 5055 Brushless motors driving 55mm . The performance is very good . I have only one problem soon after the build one of the speed controllers burnt out due to the propshaft seizing.

Brushed motors by Vickers1979 Lieutenant   Posted: 2 months ago
Hi all I’ve been running too 600 Johnson motors off one 50 amp speed controller and a 12 volt battery but the boat struggling so I thinking of running it off too esc too battery I’ve got a y lead but I do remember reading somewhere you have cut one of the coloured leads? Regards lee

Just getting started by RNinMunich Fleet Admiral!   Posted: 2 months ago
Ron I nearly forgot something vital! 😲 Clamps! Lots of 'em, various types. Pics attached of some of mine in action on the cabin roof of my Sea Scout. Large and small bulldog clips are also very useful. 4th pic shows some clamps for the bigger stuff. 5th pic some useful hand-tools, incl. both metal and wood hacksaws - indispensable 😉 6th pic is an Exacto set of scalpel / chisels. Useful for all sorts of cutting, trimming, scraping jobs. 7th pic, of course the ubiquitous mini drill and bits from 0.5mm upwards. Pic shows the box I made for the drill and speed controller, and to mount my mini table saw. In the top left corner is a mini jigsaw. Not essential but very nice to have. All three run off the same DC controller which the drill is sitting on. Last pic; set squares (various sizes) and measuring sticks! The black object is a rubber backing block for sandpaper strips. Saves the finger tips😉 Cheers Doug 😎
