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.
Extremely impressive, a water-cooled four stroke with reverse. You must have some great metal working abilities and nice equipment. Video was fun to watch! Joe
British Power Boat 64 ft RNZAF HSL scratch built 36" R/C model with twin systems including sound. Brushless 2000kv w/cooled (pump) in-runners, 30A car ESCs, 2200mah 2s LiPos remote lights etc. Started off in 1940, new with the RNZAF and had many modifications over the years till decommissioned, including machinery reduced to twin 671 Greymarine GMs (from the original 3x 500hp Napier Sea Lions) which were finally removed around 7yrs ago and replaced with a single 650hp GM Detroit 8v92T1 (still does 20 knots in its latest configuration ! - see this on the photo gallery of this model) This boat is in far better condition than the ex Phil Clabburn restoration of HSL 102 (he didn't have much to start with) and the hull has never had any major rebuild apart from being glassed to the W/L. Even today there is no way most people would pick it for 80yrs old. Those hulls never age! (ie some of the beautiful 'Whale Back' conversions still around)
Thanks for the positive comment, and yes, it''s a great pond, part of the Gulf Harbour development on the Whangaparaoa Peninsula in Auckland. it is home to the Gulf Harbour Radio Yacht Club, the members having built the jetty, and they race a number of times a week. I am about 15 km away in Red Beach but its worth the 15 minute drive on a day such as this one.
Boat is Scratch built 36" British Power Boat 64ft High Speed ASR Launch which belonged to the RNZAF. The launch was one of the 22 built and was shipped to NZ in 1940. it was the only one of its type in the Southern Hemisphere. Model has twin motors, ESCs, sound units etc. Has remotely switched water pump for water cooled brushless 2000kv in runner motors and remotely switched lighting. Uses 2x 2200mah 2s LiPos for drive and 1 1800mah LiPo for the pump (also a separate battery for the LED lights. Boat is built with strip planked balsa on ply frame and fiber glassed. Deck is ply, wheelhouse is varnished balsa. The colour is as it was for most of its time in the RNZAF . Took about 5 years on and off to build and finished it last year. (please ignore the time date - can't get rid of it .
This is my scratch built 36" RNZAF British Power Boat 64' HSL (arrived in NZ 1940). I actually went on board this vessel in 1968 when it was still in original form (the RNZAF having disposed of it in the 50s) This vessel is still around and has been recently re modelled (2nd time since early 70s) and I was lucky last year to have met the present owner and go on board (2nd time in 49yrs!)and take a few photos. The vessel was modified a number of times by the RNZAF over the years (air intakes, removal of the fore deck machine guns, wheelhouse turret etc so I sort of went in the middle. I found a few drawings of the type in an old mag which had side and top views plus the bulkheads and their positions, so I took them along to a copying shop and kept enlarging them until I had the desired proportions. This worked out quite well and using a few methods from other models I had built, managed to frame (ply) the hull and then fully strip plank it in balsa. it was then fiber glassed. The deck is ply, lined and varnish stained. The wheelhouse is varnished balsa with the top removable for access. The wheelhouse interior has detail such as controls, instrument panels, skipper, steps to wardroom etc but is not too detailed as it is not seen. The boat has full lighting by remote switch, lights are all LED.
The propulsion side has dual everything (motors, ESCs, sound units), would have had 3x but ran out of space! Motors are 28mm 2200Kv water jacketed in-runners (cooled by remotely switched pump) using 30A Chinese ESCs (have 5A BEC, Fwd and Rev). Twin sound units are 'GT Power' car units which have around 40 different sound selections, from Cosworths to diesels and are computer programmable (as well as manually on the unit ) for various functions. I am using one of the v8 sounds (8 cyls short in my application) which I think is as near as you are going to get to 3 Napier Sea Lions (for which there is obviously no sound available) They 'start' 'Idle' and are fully proportional in fwd and rev and can sound quite realistic (will attempt to put up a vid later).
Batteries are 2x 2200mah 2s 20c LiPos which will last around 2hrs at least of sailing (they also run the sound units) Still have a few small things left to do (have just made wheelhouse air intakes) but don't want to get too fiddly. Just want to keep it a practical model.
Thanks for the kind comments. Planking did take a couple of days but was not done all that neatly (just clamp and cyno) as I was glassing it later - it was all thin resin coated inside to seal it). Planking was just a hint at the original so you could just make out the planks through the glass. Have included a few more pics of the motors and interior which is not that flash but is unseen, (more for the fact that I had seen the original and was sort of putting down what I remembered from when I was 15) There is a small picture at the top left of the stairs which on the original, was a Photo from an HSL looking off the Stbd rear 1/4, to 2 64ft HSLs side by side climbing over its wake at speed
The stair set is the original from the wheelhouse to wardroom, which has been kept and used again by the present owner (down to utility room in front of engine room) and still has the original 'POWER BOAT' rubber treads (not bad nick for 79yrs old!)
This is a restoration of a launch I was given that was found in a rubbish bin on a farm here in Auckland it is an old RCM ? plan built 'Fairacre' and was pretty rotten when I received it as it is made in balsa and had been wet for quite a while. I stripped it down, re 'planked' large portions of the hull and fiber glassed it, re- built the cabin, re- marked the deck planks, fitted lights, curtains (ex Graupner Commodore bits from the 70s I had kept), stern ladder, cleats etc. it is fitted with a 540 brushed motor (originally had an old Graupner monoperm) and 70s Graupner ESC and Using 2.4 Radio gear. I still have a few things I'd like to do such as a re-wire, fitting chine spray rails, better motor and maybe some safety rails, but for now it does the job.
Proboat Alpha - ready to run, model of PBR, Patrol Boat Riverine, used by US Navy during Vietnam conflict, served 1967 -1972.
Images show basic detail, 1/18 scale, with crew. Bow gunner servo is linked to rudder. Comes with Navlights, looking forward to a night sail.....some painting added to weather craft, as well as painting radar housing a lighter grey....and the canvas roof over wheel house....a little artistic licence with vessel numbers......Brown Navy did'nt always have numbered vessels....but could'nt help myself.
scratch built, with out board motor,2 blade prop, 30 inche long, still need to install nav lights, chairs are from doll house, runs on Lipo battery, runs and turn excellant, and no that is not a beer in his hand it's a bottle of coke
Dunmas kit MACk 5045 motors and hardware. Two layers of 2 oz. Fiberglass cloth on hull 3/4 oz cloth on deck Klass Coat epoxy paint . Model has cabin lights and running lights. Power 2 x 7.2 packs.
Our club had our Fun Run today.We operate out of Humber Bay in Toronto whilr the weeds are down.The sun is finally cooperating.
We have two ponds to run our boats in.The Sailors run in the big pond and the scale members run in the smaller pond.Attached are a few photos of the day.I must mention that the first picture is a new construction of a Marblehead out for a test run.The Canadian Coast Guard Ice breaker is totally scratch built with working radar and lights.This member works on his kitchen table.We found out later that he was born on a kitchen table.
Hello frends
here is som pictures of Celtic Ambassador , it is evening and the lights are on.
it looks real good when she is in the sea when i go booting in the evening
Hi Jugge, I didn't mean you should buy these lamps, just make some Light-boards, like in the pics, to add to your own lamps! 😉
Thin brass strip does the job and is dead easy to solder. 👍
OR; buy those complete lamps and simply wire them in series across your 6V supply: 3V + 3V = 6V 😊
Whatever; have fun doing it, cheers Doug 😎
