Trying to learn to use this forum properly I am publishing a video that shows an experiment I did to find out how fast the stepper motor could turn. I am using in my model of the sailboat Carina 2 stepper motors like the one shown in the video to work as a winch to control the position of the sails in a system solution where I am realizing this my own way to implement the sheets as shown on the original sailboat Endeavour. This requires my sheet control system to control the length of the sheet of the mainsail i.e. over a range of 8.3 meters. This requires the drum which is turned by the stepper motor to make 21 full turns. Details will be published in my report from scratch of building my Carina.

Scratch built. Plans drawn up from photographs. Now a break water in Port Philip Bay, Australia

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.

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.

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.

I Scratch built this model in 2012 based on Mark Porter's plans.

A short video of the first trial of my Genesis 9000 Offshore Power Boat. This is a boat to use whilst I build others.
The trial was seriously hampered by a faulty main switch. The insides must have fallen apart during transportation. I did manage to get an electrical contact to get around five minutes of the trial. The boat ran well but I will have to adjust the rudder to give more movement. Just after the video ended, the boat hit a ripple whilst turning and flipped over. No water entered the hull so all was good, except the switch now refused to work at all. The trial was ended and unfortunately will now have to wait until I return to my river in August.😤

My uncle Peter was a flotilla leader with coastal forces in the Mediterean, in the second half of WW2 . My late father, Douglas, his brother, built the pictured MTB in 1956. it ran with i.c. power until 1962, when it was mothballed.

I recently restored and upgraded the model (brushless motors etc) and thought that it would be great to take the model all the way down a lake in Devon to demonstrate it for him. Not having any local knowledge, I put a request on this excellent site, asking for help from local guys and must say that the site has some wonderful subscribers who came forward with help and support, especially Keystone. He was brilliant and greatly contributed to make the visit a great success. thanks, mate. My uncle and the other members present greatly enjoyed it, though the windy, cold conditions rendered the rum tot most acceptable!! The photos are self explanatory. The tug was there as a rescue boat if required.

Many thanks to all Model Boats' members who responded to my request for help.

CB90 Model boat, 52 inches long performing 360 degree rotation on its own axis.

The Combat Boat 90 (CB90) is a class of fast military assault craft originally developed for the Swedish Navy by Dockstavarvet.

Powered by two 9.6v Graupner 700 turbo motors (no-longer in production).
Two Mtroniks Viper Marine 25 is a Brushed Speed Control designed specifically for use in RC model boats, it has a 25Amp motor limit and has proportional forwards and reverse functions

A few shots from today at the Portsmouth Model Boat Display Teams new club house at the Explosion Museum, Gosport- the tide was out so no boats on the water ☹️
So we sat back with a coffee and some ice cream, enjoyed the sunshine while watching the tide come in ( to give us an idea of how long either side of high tide we have usable water ) and the various boats going around the harbour with a backdrop of HMS Queen Elizabeth. The ex USS Chesapeake/ex HMS Revenge was given an airing in the sun. She is now the Minerve/HMS Minerve depending on which side she is fighting on

"Triton" patrolling its homeport, the Loisachbad, located in Garmisch-Partenkirchen, Germany.😁

Billing boats, which took me 3 years to build.Hull was planked and theh fibre glass. Boat has full functional remote with seperate port starboard control,rudder and bow thruster. full inside and mast lighting.
