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!)
My dad built this over a long period of time, starting in the '80s. The hull is fibreglass and the rest is scratch built from plastic card, balsa, ply, wire and anything else he could adapt.
Although he installed the motors, props and rudders he never completed the RC installation or tested it. I inherited his boat models a few years ago and wanted to "finish the job", getting the model on the water. After installing the RC gear and batteries over the last few months, this weekend was the first sailing outside the bath at the Valley Gardens boating lake.
Happy to report that it sailed really nicely, seems to be reasonably stable although I did restrict it to calmer times when the MTBs and faster boats weren't running !
HMS Cadiz was a battle class destroyer, laid down and launched during WW2 although she didn't receive her commission until 1946 so didn't see combat with the Royal Navy, serving with the home fleet. Due to the changeover in pennant numbering she was originally allocated R09 and later, when the admiralty decided to revert to the D for Destroyer pennant numbering she was assigned D79. To reflect this my model has D79 on the starboard side and R09 on the port side.
She was sold to Pakistan in the late '50s, and renamed PNS Khaibar. She was sunk with the loss of nearly all hands in 1971 in the indo-Pakistan war.
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
Scratch built from a 1975 free plan, hull is balsa frames sheeted with basswood and covered with 3/4 oz fibreglass cloth, superstructure is styrene sheet, missile launcher from balsa block, forward bofors torpedo launcher from styrene sheet and wood dowl, photo etch ladders, white metal handrail stanchions, other fittings are brass and resin, lw-02 radar and directors are from shape ways rudders and stabilizers are balsa block, you get the idea.
A very nice execution of the old Model Boats free plan. I still have those plans (somewhat tatty after all these years) as well as the MB magazine they came with. How does she sail? Best regards, Glyn
Many thanks for your kind words, I've not sailed her yet, only test tank and had to up the water line a little bit for more stability, I also scaled up the plans to true 1/96 as the plan is around 1/100, the 1/96 fittings I bought from fleetscale were out of scale to the plan, and using the 1.1 water line length noted in the magazine article.
Upgraded to Brushless 2x1100kva Turnigy motors, Scratch built 1/24 scale. I've included a photo of a real one, just in case somebody else tells me the colour scheme is wrong, East of Gibralta they where white. I'm sitting on the engine hatch nearest the camera, that was 1969
Very nicely done Jeremy👍
I've pinched your photos 😁 for inspiration to convert the rather basic H/C kit I have.
it just has a boring 'bubble' on top 🤔
Cheers, Doug 😎
Hi Model boat enthusiasts,
This is a photo of almost completed 2 model boats I have almost completed. The Sea Queen 50 years old find. it was found in an attic in a kit. The kit was in a very poor state and most of the timberwork had to be glued back together or remade. I had no plans for it and had to source a copy from the Model Boat website. it is a very nice model. The pilot boat was scratch built and sails very nicely. I have been building boats for about 30years and have built over 25 boats, scratch built all of them. I have included photos of some of my boats.
