turbine
Hull is from boot sale. Turbine is 3" dia and is driven by twin boilers. I made them both. Speed is not blistering but it goes !!! Boiler pressure is 100lb/sq in. Les Breame

KD Perkasa
I acquired this boat part built some months ago through Dave M.
I have not put too much scale in detail but I am quite pleased with the overall finish. it is powered by two brushless 1250KV out runners and in the first sea trials I used 12v lead acid batteries. (That video was posted a few weeks ago - mdlbt.com/26793).
This video shows its second sea trial after I was persuaded to use lipos. The difference in performance is very pleasing.
Thank you Dave M for your help and advice during the build.

    Thank you for your compliments.
    This is in fact my second Perkasa. I built the first one about 40 years ago (see photo), before the introduction of the GRP hull. Losing interest in the hobby some years later, I sold the boat and have lived to regret it. (I was also the proud owner of a 37" Aerokits Crash Tender powered by a Frog 2.49cc diesel. That went the same way!)
    The first boat was quite lively powered by a Merco 61 i/c engine.
    No pictures of either I'm afraid.
    Hindsight is a wonderful thing.

    Hi Edward, its a fine balancing act of electrolysis to hydroide gas, compression then ignition but utillising vacuum formation as an assisting force to the power stroke so effectively making it a one stroke which sounds odd.still in development ive tried turbine,oscillator pistons and hydraulic recoil as end movers but the best seems to be the straight reciprocator. its scary,how the hell can they tax water??? cheers Neil.

Norstar Wave Princess
Built this Wave Princess 30 years ago meaning to use it with my children. Languished in attic since and now retired going to resurrect her for Grandchildren and would welcome any advice on motor size, prop shaft length, Propeller size etc etc. Picked up an as new MacGregor Digimac 111 transmitter receiver and servos at Boot Sale for £5, seems fitting I should use it for the old girl.

She has full fpv from the wheel house with a 360 spin HD camera and have even put a digital amp meter so u can look at to and see how mUchida power u have left full running lights controls off hand setc to twin brushless motor water cooled and a large 100 amp esc with air fan and own power supply going to take her out tomorrow for her maiden voyage.
