Bonjour Sorry but that is almost the full extent of my French.I am hoping that all my European friends are more educated than me, and can understand English. My intention is to build the Tornado using a Villiers 3T 325cc two stroke twin engine. This engine is my choice because I have had it in my shed for about 10 years. It is brand new and has never been run yet. My concern is that it may not be powerfull enough for the craft. The rated horsepower is 18hp. I am considering running a multiblade fan directly from the crankshaft. I would apreciate any advise which anyone can give Merci bien |

"On this hull it would be possible to mount a 100hp engine, but this would require some hours of practice " Hello Pascal, Could you explain me and write a bit more about mount much more heavy engine - eg. 50HP??? I am planning to build a Tornado with 50 HP Suzuki engine( 1000ccm). My engine and reduction drive belt are quite prepared- engine RPM 5000max - drive belt ratio 1:1,84, so fan RPM +/- 2800 RPM. Because, the engine weight is about 90-100 kg- I wonder if any changes of construction are needed?? eg length and widith!!! If I use Suzuki engine with total weight 100kg + hull weight aprox.80 kg + driver/pilot +/- 90 kg- so , total payload will be about 300kg. What do I need to know before start building a hull ??? Are any changes in construction details required??? What about the Fan and splitter plate??? I made some calculations using Multi Wing Optimiser programme and in my opinion the best solution is 7 or 9 blades fan with diameter 800 mm.( apendix- fan data and graph). Please, send me some info. Regards , Ian |
