Well thats it folks I built this as I was getting fed up with the price of Model glow fuel around the £30 a gallon mark . . .  hello fuel makers its a hobby . . . and a gallon of petrol and oil mix works out to around £7 a gallon 
 ( two stroke oil is around £11 a Litre and you mix 300mm to a gallon sort of )

 I have added a pulpit rail and figures just to get the finishing touches done .. . 
She runs for about 15 minutes on a tank full and the joy of a big boat on a lake in summer is so refreshing
