I have three of these boats built them up from spares, brought on Amazon.
Only one has the original motor, 14.4v,
The deep v , small size and heavy boat, makes this a power hungry boat, difficult to get on the plane, with anything but the original motor.

Ripmax Tomkat,
an original design built for a 12in passenger, but can run without and will go that bit faster, upgraded to brushless and 2.4 G radio and lipo battery.
Originally had a 550 type motor brushed esc, 27mhz radio, and ni-cad battery, main fault of boat is that it has a very poor reverse, as it has been designed with a surface piercing prop, so only effective in forward motion.

Pursuit Boat 7
In 2019 I started this racing boat but as of yet have not managed to get it to a lake it runs on 14.8v lipo with 3674 High Performance 2650KV Brushless Motor.
Please note rudder is hinged so if it hits something it lifts up, to prevent damage.
Put in water in last days of September 2022, generally OK, but cut out on full power , I think the battery has had it, brought another to retest.

(Naval Ship) HMS Sabre, Scimitar-class preceded by Archer-Class
Please note this is not a scale Model it is a club racing boat (semi scale) and will get many knocks and flips during racing.
The trials of this boat went well I remember comments made by members of the Eton park model boat club (Norwich) on how fast and quiet the boat was.
There was a problem on sharp turns it ventilated and lost power, I tried various modifications over the next year, but in the end knew the prop was too close to the transom.
So July 2020 the boat was stripped back to the basic hull and holes filled, then motor, shaft, servo and rudder were re-positioned.
Another trial will then occur, also I have decided to seal the windows in the cabin and fill with polystyrene to make the boat self righting, as last time it flipped over in a race it remained inverted until it blew to the edge of the water.
upload 3 photos to add to original 3
2018 Just finish this little boat, need to have its first trial on the water to measure current draw and perhaps modify the prop size.
Make sure water cooling works, and the thing steers ok.

(Fire Boat) RAF Fireboat (vintage) Aero
Now sold to a man in Kendal in 2021.
Ebay job ยฃ50 Old Vintage Aero kit 34in Fire boat needing a lot of attention, with delaminating plywood, old glue, old glow-plug engine mounts with electric conversion, and after removing a metal shield I discover an vintage (1970,s Ripmax Bullet 30 Motor the dogs bollocks of electric racing of its time capable of running 24v at 15A.
300W for a brushed motor.
Started by revamp rear pit by lowering servo and rudder and building sub deck, storage lockers, tow hook and ladders.
Remount the motor with an aluminium mount with custom screw positions.
Block windows with 1mm ply.
Foam front half of hull to make unsinkable.
Make centre decking area.
Repair and build up on cabin roofs and walls to centre deck.
Rewire add ESC and servo.
Remove broken and unusable fittings such as large vents, some missing unable to match again.
Problems with old gloss paint crazing the modern spay paints.
Build some fittings eg Water cannons, life belts,
Build new battery trays,
Painting the boat now in progress as of 20/04/2018
Boat has be roughly painted but is not finished, as fittings are now required, added a RC system an gave it a test run.
the performance was adequate on 14.4v and great on 17.2v see latter pictures on the pond. the motor did get hot after about half hour of use.
the motor is rated at 24v but I think a smaller prop will be required for that voltage. Excellent performance from a brushed motor.
Added some stickers and I have now added a 12v fan and ventilation between cabins as the motor required some cooling and was in a sealed compartment. (Motor: Bullet 30) (ESC: 24v 15A Electronize) (9/10)

(Racing Boat) WL 915
Now sold in 2021.
WL 915 ready to run Brushless 2.4GHz RTR Electric RC Speed Boat.
This RC boat is capable of reaching speeds up to 25MPH and anti-capsizing technology?
The flood chamber in this boat causes the boat to struggle to get up on the plane, in the end I filled it with foam, and put in a new rudder offset to the right, it now goes well, and I haven't flipped it yet!
Features:
โขElectric Powered
โขCapable Of Up To 25MPH?
โข2.4GHz Transmitter
โข11.1V 1200mAh LiPo Rechargeable Battery
โขBalance Charger
Specifications:
โขLength: 17.25 inches
โขWidth: 6.8 inches
โขHeight: 4.7 inches
I will be modifying this little boat as it has a few annoying problems they are:
1. The flood chamber fills quickly and once full hampers the boat in accelerating and getting on the plane.
2. You cannot run the boat slowly as the flood chamber fills
3. The self righting is not 100 percent reliable.
4. Binding is initially difficult
Mods
a. Replace cabin so boat lies flat when inverted.
so able to use rudder extension to steer when upside-down.
b. Racing rudder side position out of prop-wash and aids torque effects.
c. Fill float chamber with foam so gets on the plane quickly.
d. Cut down rudder as too long (95mm) to 65mm.
The cabin will be finished and painted properly after testing.
On testing the rudder was reduced and performed well once it got going but still have problems getting it up on a plan it feel this could be a balance issue, needs more mass at the stern. (Motor: outrunner) (ESC: unknown) (5/10)

(Fire Boat) Grimmershorn II
The Motor vessel 'Grimmershorn' was built in 1956/57 by Hansa Stahlund Schiffbau GmbH at Koln-Deutz for the Waterways and Shipping Administration at Cuxhaven.Her Daimler-Benz four stroke diesel engine had an output of 500hp. permitting a speed of 11.5 knots.
The model hull and deck are vacuum formed ABS, timber work of precision cut ply, 2 full size plan sheets and a construction manual along with a fittings pack complete this kit.
Technical Data
Scale:
1:20
Length:
1038mm
Beam
305mm
The Grimmershorn was the second major kit I purchased from a model shop on the outskirts of Harlow in Essex back in the 1980s.
The Krik kit is still produced and sold today. My build was a slow and lost enthusiasm so after completing the hull, deck, motor and bow thruster installation I gave the boat to my father in-law who completed the superstructure and sailed the boat for a while, eventually the boat was given back to me when the father in-law moved house. I then repaired the rudder, added a moving radar, a adjustable water cannon and pump also various extra fittings such as a detailed life raft and crane, buoys and captain figure.
thus renamed the boat as Grimmershorn II a Search and rescue fire boat. (Motor: 950) (ESC: 15A 24v) (5/10)

(Racing Boat) Interceptor
Zoom 1 (Interceptor) Mono boat.
Built from a Glassfibre hull, brought on Ebay for ยฃ35 the hull is a slim mono racing type with a self-righting side cabin it runs a 1400W 14V 2958 4200KV Brushless Motor and 29-S Water Cooling Jacket with additional air cooling fan.
I did not want to use a flexi drive as high maintenance and prone to failure so the shaft runs via two universal joint one at each end. the propeller is a 38mm copper alloy
The ESC is a 200A and water cooled the twin rudders supply separate water one for the motor and one for the ESC.
The rudder are positioned to reduce prop-walk and are hinged to prevent damage if hit a object in the water and ride adjustment.
Turn fins and trim tabs for ride adjustment were provided by a spares kit for another boat. also foamed and added an inner sealed hatch, a rubber bump strip and safety loop.
The Boat is fast and over-powered used at half throttle, may use a 7.4v lipo instead, the self righting works well.
20th April 2018 while running on 11.1v the boat stopped, no response on retrieval it was found that the manufacturers battery connector had melted and the connection lost see later pictures. the battery was made by FLOUREON and was a 35C with 5500mah capacity the 80A fuse had not blown. (Motor: 2958 watercooled) (ESC: Unknown 200A) (8/10)

(Naval Ship) PT 109
PT 109
The famous ww2 PT boat skippered by JF Kennedy (later to be President of the USA)
This has be one of my have to have model boats and it was by luck that I found one for sale on a model boat club's web site in 2013, ยฃ100.00 later and a journey from Cumbria to Yorkshire and back, I had myself a ProBoat PT 109
This was a ready made RTR model when new and is 40in (1m) long, the boat needed some small repairs but after a test run I found that the running gear was noisy and on investigation discovered that both propshaft were bent and had no bearings from new, the couplings were just direct connections.
So with great care I replaced both prop-shafts, propellers, coupling for two double Huco's (universal) and the single ESC by two new Aqua speed controllers and both motors with Graupner speed 600's
Note I also foamed the front compartments to make it unsinkable in theory. (Motor: Graupner 600s) (ESC: 2x )
2020 update, removed Aqua speed controllers as they went full throttle if they lost RC signal, replaced with Mtroniks 25A jobs (7/10).

(Naval Ship) Perkasa Class
A Malaysian Fast Patrol Boat Perkasa produced by Vosper in1966,she has 3 gas turbines engines and a speed of 54 knots, and diesels for cruising.
The model was built in the 1980s but has only recently been fully powered up for planning speed, handle choppy water very well, port and starboard motors are 2x Graupner 600 7.2v and centre motor is a 700 type motor, 3 shafts run 3x 35mm propellers and it has two rudders, the guns are remote controlled (Please note the stern/rear gun is not accurate and is just a copy of the forward gun Bofors 40mm and not the 20mm Oerlikon. Search lights, radar, running lights all work
the 3xESCs are a cheap China ones that do the job but need to go to neutral before going in reverse, just use self centring joy sticks on the transmitter. (Motor: 2x 600 + 1x 700 type) (ESC: China) (8/10)
