[Score: 9/10] 28"/10000g Al Khubar 2 Capable of 3mph and a runtime of 120mins Twin Propellors (4 Blade 50mm) Geared to a Torpedo 500 (4 Blade) Powered by Lead Acid (6v) 7Amp/h Batteries - Comments: This is a Model Slipway kit of a series of 3 tugs built in 1976. In 1977 she struck a submerged object and sank but was subsequently salvaged. Last known Lloyds record was in 2002 being operated by Grandi Lavori – Fincosit S.p.a. Genova. Al Khubar 1 was destroyed in 1990 in the Iraq/Kuwait conflict. Al Khubar 3 is still operating, having been convered to tug/dredger working under the name of Flat Holm.
I have recently bought an old Model Slipway, 1/20th Vosper Kawkab class patrol boat, and I've been trying to find suitable figures to fit without success, I assume they should be approx 80-90mm. Any ideas please? Thanks in advance.
Hi all Just got around to start building a Modelslipway 1/16 Tamar . This being my first model boat and RC I am at a loss to what motors to fit . I would prefer to install conventional brushed motors ,but the ones recommended a few years ago 600 eco are no longer available Would be grateful for any proven recommendations ,or any easy setup using brushless without cooling . Trying to keep it simple and not too expensive Thanks in advance for any comments .

Conserver Capable of 3mph Single Propellor (3 Blade 45mm) Direct Drive to a Electronize 545-12 (3 Blade) Powered by NiMH (6v) 4Amp/h Batteries Controlled Through Mtroniks Viper 15 ESC - Comments: Model Slipway kit of a full size buoy maintenance/survey vessel still working out of Leith harbour, Edinburgh. Maiden voyage took place a week ago, it still needs work to finish it. It performed really well with a very tight turning circle. Further testing shows a more realistic speed using a 6volt power source instead of the original 7.2volts.
Decided to advance LI-PO plans and try a 4S 4000mAh pack. This weight of this pack reduced overall model weight by 8 oz, so it is now 9.6 lbs, close to the original target. Was also to slide the pack further sternwards until it touched the inner face of the RIB slipway, about 2.5” from the stern. The effect on the waterline was limited; the model now sits slightly higher with the waterline remaining level. Slowly increased the speed of the motors to assess the LI-PO performance. There was a significant improvement. There is no need to use “ full” power as it probably exceeds max scale speed. As the model accelerates the bow lifts exposing an area of the red bottom paint. The wake streams down the side of the vessel and curls off the spray rails. She looks very realistic. The attached picture is at part speed. The model is totally controllable, the influence of the centre fins is noticeable as the heeling is not pronounced unless extreme manoeuvring is tried. After 90 minutes of use decided all original objectives for the model are now accomplished. She looks and performs well. The next task is to tidy up the temporary wiring and fit the LI-PO properly. Will also have to re-route more accessories through the voltage reducer fitted for the bow thruster so the LED lights are not overpowered. Have also bought a small r/c controlled child’s jet ski toy with the intention is using the drive and control system in the RIB. It will require much mutilation of both the jet ski and the RIB to work them in together, but think it can be achieved. My next blog will tell.
Hi all, have just finished testing the Caroline. Dry weight including battery was 13.2 Kilos. placed in paddling pool and she sits nice and level, I attached a set of fishing scales to the transome and tethered them to bench at end of pool. Slowly increased power and at full throttle gave a reading of 7kgs on the scale, at half throttle still showed 5kgs and water was lifting over poolside. Although pool is only 1ft longer than boat enough power to lift bow, in fact she tried to climb out. So well pleased with results👍. Battery lasted 1.25 hours at half throttle. So looking forward to her maiden voyage on Worcester Model Boat club open day, I feel like a 5 year old looking forward to xmas😊. My son is going to help me on the day as she's such a big lump, should realy have a slipway launch. Hope some of you will be there to watch. Going shopping now, fire boat needs a new battery for fire fighting pump. Best wishes Colin. (photo WITH BLUE BACKGROUND was before refurb)
Hi Alan. I am building a model slipway tamar at the moment,I have completed all the main construction. There are one or two things you need to look at and study before assembly so if you decide to purchase a kit mail me and I will help in any way I can with the things that I found during my build.
