Surely a detuned version with say 25-30hp would be more than adiquate for a paramotor engine ? Then the working life could be extended and air cooling would be a viable option. Something like the Wolfe XR50 in aircooled form with a bit of lightening would be ideal. Also I can't see to many problems with the likes of Nikasil on alloy (I believe it's something similar). What would be ideal is to get someone to machine a cylinder from aluminium and use someone elses rotor/crank. I suppose if you were to do without a clutch you could use a very lightweight flywheel. I've had a similar idea myself for years but cost has been an issue. There is certainly much potential out there. I did look at the Parajet but it's basicly a wlofe engine (despite them saying it's their own) And it's very overweight. I recon what's planned here is very doable I was also looking at the new batteries from 123 systems (read dewalt xrp). Electric is almost a viable option now. The future is looking good.
