This is a 49" Perkasa built from a ply Precedent kit - the build blog is on this site. Videoed from a 46" Fireboat on a lake in Western Australia. Neither boat is running at top speed, which is spectacular but overscale! Both boats have identical brushless motors. Apologies for the video being a bit long, and for the water on the lens, but this is a first attempt and I hope you enjoy the music.

This Higgins PT boat was built and sailed by a good friend of mine. it is scratch-built. it uses a single Turnigy 3639 1100kV brushless motor and LiPo battery. it is pretty new and has not had its number painted on as yet. its performance is excellent.

Zoom 1 (Interceptor) Mono boat.
Built from a Glassfibre hull, brought on Ebay for £35 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 200W 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 you hit a object in the water and also for 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.

Brought this vintage Aero Kits RAF Crash Tender for £50 from Newcastle area, it is the 34in version.
To my surprise at home I found that it had a Bullet 30 motor installed these motors were the top drawer motor of early fast electrics in the early 1980's and its the only one I've ever seen, it can run on 24v and pull around 15A giving 300w not bad for a brushed motor.
due to the power of this motor I have modified the hull under the water line with turn fins and trim tabs to reduce torque roll and improve turning stability, the underside is incorrect already as it only has one propshaft, where the original had two and I believe that both props turned in the same direction.

The Pictures here show some of the work in progress I have remounted the motor and added a speed controller rated at 24v
I have remade the stern compartment and rudder gear under it.
I have blocked windows and foamed the front half of the boat.
made missing parts and repaired delaminating ply.

Note old ply is not as good as modern, the glue is not as water resistant.

Have painted the hull and have just ordered the decals from Cornwall model Boats :-https://www.cornwallmodelboats.co.uk/cgi-bin/sh000001.pl?WD=hose%20fire&PN=becc_fire_tender%2ehtml#aB_2dFTS1_2e32

The 34in is 1/16 scale

Fitting can be brought but many are cast white metal and can add weight to the boat, I have made two water cannons and plan to buy plastic fittings from this site.

This has turned out to be a task that is difficult to assess how much effort and money to spend on a hull that has been built by someone else (say no more).
Have just finished the steps for the stern compartment.
Painted and now for the test run.
the Bullet 30 motor ran well between 14 and 18v,

built from a Vernon plan using lite ply
27" Long x 6.75" Wide
30 amp esc
3 cell 5000mah lipo
1000kv Brushless Motor

This is Brian Clewes Hovercraft on a frozen Boundary Park Lake in Cheshire UK.
Our resident cob swan and his wife were sat on the ice probably hoping we had brought some feed. They don't bother us and we leave them alone. I should have filmed them taking off later, not an easy task on ice for one of our largest birds.
The hovercraft has two brushless motors and uses a LiPo.

Mobile Marine do a Skimmer hulls that you can use to build your own skimmer. This is the larger version and they also do a smaller version.
I have used a 2208 brushless with a chopped down 10" prop, cheap 10amp ESC and 11.1v 2200Ma Lipo.
Good when the weed gets too bad!

An old favourite from my hovercraft phase. Runs really well on land and especially water. Although no reverse, it will auto-rotate on the hover, so when pointing in the desired direction on with the propulsion with the brushless motor and away she flies.
Realistic in operation. Looking a bit work worn now. Could do with up-dating with Lipo batteries which would make it even lighter. Seen here with lift motor running with skirt inflated. Steering
interesting, with twin air rudders. Must get some videos of the action.

A challenging project 10 years ago. Scratch built model of theSRN3 built under licence by the US for use in the Mekong delta against the VC in Vietnam. Very light construction with liteply.
Two ESPs control brushed and brushless motors for lift and propulsion. Motor tube ball-raced at each end with a 9x6 pusher prop. Realistic performance and sounds like a turbo prop. Tricky to control in anything stronger than a light breeze. Best on water.

Vosper 73ft Type 1 MTB - Scratchbuilt. Now running two brushless motors and NiMH batteries. Photos previously posted. 1/24 Scale

Fairmile D MTB623 belongs to a good friend. This boat was also featured in a previous video with my Fairmile D.

The lake was a bit choppy with realistic sea conditions.

1/35 Scale model of the La Combattante IIIB Class Fast Missile Boat of the Hellenic Navy.
The boat is scratchbuilt. it is 1606mm long. it has 2 brushless 720Kv motors and NiMH batteries.
The 76mm guns can traverse and elevate. The 30mm guns can traverse. Both radars rotate and there are LED running lights.

Aeromarine Laminates Predator 21 hull with HK 2630kv brushless outboard and Turnigy 120a w/c esc. Waterproof metal geared Servo and will have 4-6s lipo when completed.
