John,

Found this in an old plans handbook which is not the best by modern standards, but good luck with the search. Original item was one of (the four) of Vic's airscrew designs which were featured in Model Maker magazine Dec 1953 & Jan 1954.

It would be interesting to see photographs of your build.

Plans have arrived.

Studding plans and deciding if this could be built in plastic sheet or a bit of both. Twin pontoons could be easily be made in plastic with hull balsa construction.
Any comments would welcome.
Balsa & ply on order + I have plastic sheeting If I decide to go that way.

This project would obviously lend itself to using a Brushless Motor, which is new to me so any advice on size etc. again will be welcome.
Also note this is my first Hydroplane, but I like unusual project and this very early design caught my eye having never seen anything like this before.

Picture of build will be forth coming in the near future..

Hi John The plans say up to 3.5cc ic, thats 0.2 cu in or a 20 size motor in todays parlance. Looking on a model aircraft site **LINK** they say 0.2 i/c is about 300watt electric equivalent.

So up to 300w motor is a starting place. Also remember the original was not designed to carry "heavy" batteries

Hope this helps cheers Tom

John. Comments; looks good. What a lovely vintage build! A dark matt blue I fancy would look particularly vintage.

Brushless motors !!! yer on yer own there.

A call to a model aircraft shop may be warranted.

I see the large lumps or balsa at the back. I am think more like a bulkhead to secure the rear moto mount of a brushless and Blue styrofoam outer for the shape? Styrofoam is easy to shape and very light. An outrunner brushless motor needs a rear (of engine) mount.. It may be an idea to purchase your chosen motor before continuing the build around the motor area....

If I was building this, a test would be warranted before any more sculpting took place.. Finish the hull and then get it running properly before finishing the top part.

John. looks good and I think that this would be great in ana nice vintage matt blue colour.

The large lump of balsa at the rear is probably unwarranted nowadays see my earlier post.

Tom. That link is exactly the sort of thing a newbie needs, a package all matched up.

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
