[Score: 6/10] 16"/900g Arnold.S Capable of 3mph and a runtime of 60mins Direct Drive Powered by NiMH (7.2v) 1Amp/h Batteries - Comments: This is a tug boat kit by Freedom Song Model Boat there no longer selling models I have a lot of fun running this model in small pools
thanks Dave i got a seaking 120a watercoold brushless ESC by Hobbywing which handles the power well. Same motor as before got a 38m 2 blade prop looking for a 3 blade. i was originally useing the 12v battery to run the motor but it was no good now use a lipo which i have installed under the deck in front of the motor.the large battery is running the watercooling pump and is also the prefect weight for ballast.NO problems with the salt water as i have got stainless steel, brass and copper fittings and a good flush threw the cooling system with fresh water. might be some time before i can put up a video because the council is draining the pool next week for the annual winter maintenance which is a bummer as there other suitable ponds handy. cheers Allan
Hi Allan Glad to hear you have managed to get the boat running. Just so we know what is the final set up? I can see a 12v 7Ahr battery but What is the prop size & type, brushless motor, ESC. You have mentioned these before but may have bought different recently. Looks a good pool to use. As it is saltwater you will need to wash the model down after each sail and oil the propshaft. Salt crystals will destroy any bearings very quickly if you don't. Happy sailing Dave
FINELY got my Perkassa running this afternoon after spending about $200.00 on new ESC, prop and stainless steel coupling ( the plastic one shattered on the last run in about 2 seconds). I have got to much power in it but the boat runs at about scale speed on about half throttle. I am running in a saltwater swimming pool on the beachfront at Wynnum Central which is a bay side suburb of Brisbane Queensland Australia. Cheers Allan
Thanks Jarvo Ihave a 40mm 2 blade prop and the motor was running at high speed for about 1 minute. My swimming pool is to small to run a large boat at speed in, that was why a was holding it. Yes it was very hard to hold the boat at the time there was a lot of power, as you said it my have been overload because the boat could not move. Next time i will take it down the pond where i used to sail. Cheers Allan
Yes Dave I had the boat in the swimming pool and holding it stationary. The water pump was running with a good flow of water before and after the fire. I just had a thought maybe there was to much turbulence from the prop around the water intake which is behind the rudder stopping the water flow when the motor was running at speed . I couldn't see the out let as it was on the side away from me. Maybe i will have to move the inlet or something. Cheers Allan
Hi All We tested one today using PVC conduct covered with pool noodles which is a high density foam. We used hair elastic bands to hold the recovery boat to the device which also handles different width boats. The other end is faired out to help capture the other boat also if only a push is required. The forward sections can be un pinned for transport. The test today worked well on the unrequired to be rescued tug. The PVC tubes are sealed in the T sections and the removal sections forward of the joint pins.
R.I.B completed, adding about another 1 oz to the vessel weight, also added the 4.5 oz as permanent ballast. Total model weight is now 156 oz. On review of many HMCC “Vigilant” pictures, note the top of the boot-topping can be almost coincident with the waterline. Decided the slight extra weight , beyond the 4.5 oz originally tried, will help raise the bow and have little effect on the stern draft, so left it as is. Sailed again in the portable pool and now consider the trim acceptable. The boot topping is visible for the full length of the hull; she sits very much like the full size vessel. Once the ice to leaves our local pond will see how well she performs in open water and what the run time will be. Have tried several approaches to making a R.I.B launch / recovery mechanism, but with little success. Seem to be able to either launch or recover using a single radio channel, but not both. Now decided to shelve this feature until inspiration strikes!
I popped into Huddersfield Society of Model Engineers, they have an outdoor swimming pool for the boats, cater for rc trucks etc and have a working train for visitors to ride on bu it's the boat part that i'll be getting involved with. There is one closer to me but it's a lake and quite choppy...my first sail will be Saturday when i'll join the club :-)
For the third year, the North West Ship Show will take place at Old Christ Church, Waterloo Road, Waterloo, Liverpool on 30 September 2017. Organised by Coastal Shipping magazine, there will be exhibitors and traders from across the UK with books, photos, postcards, model boats, collectables, ephemera, boat kits and artwork.
Hi Dave, The 1/12 Bluebird is brushless (all running gear from PMB), as it's made from balsa, I've waterproofed everything with sanding sealer inside & out. To be honest I was planning on taking it to quiet stretches of the Leeds/Liverpool canal as I didn't think any scale model boat clubs would want anything to do with my boat, but I will have a look at what clubs there are locally. The 1/4.2 will be IC powered, I want it to reach a scale speed of 300mph so if I can hit 75mph in the real world with it I'll be very happy. I hope if I can keep it light enough a couple of Tiger King S27 Evo's will get me there. I've emailed PMB as they don't have any stock at the moment, to see when they are due some in, but I've not received a reply yet. Plan is to buy 1 engine initially so I can plan the layout & while I'm carrying on with the build I was going to drop it into this eBay hull to see how it performs. I have a couple of Enya 40ss motors, I'm going to try one in the Short Stuff & see how it goes. I can't cope sitting at home watching the telly, I like to keep busy😎 Cheers Wayne
[Score: 5/10] 15" built from scratch Single Propellor Direct Drive Powered by NiCad (1.2v) Batteries - Comments: This is an unfinished boat i started making for my grandson about 3 years ago. I had it running in the swimming pool with 1 AA battery temperately wired up to the motor. It is made out of balsa and coated in resin
[Score: 5/10] 49" K.D.Perkasa Single Propellor Direct Drive Powered by Lead Acid (12v) Batteries - Comments: I started building this boat about 15 years ago and still have not finished it.I have to do all of the finer work on the decks and mast. I just added a water pump last month to keep the motor cool . The force flow system did not work with little or no water getting through and the motor and controller got very hot after a short running time. I have not given the boat a long high speed run yet but test in my swimming pool seems satisfactory with the pump putting through a large volume of water
