It could be this small with 15-20 hp engine;

Initial structural design…

Some toughts on paper.

Bigger engines allow a bigger pilot to fly.

ZDZ has 210 ccm and 420 ccm engines too.

I am surprised nobody has mentioned the E-Go project http://web.me.com/tony.bishop/e-Go/welcome.html
They are already building this, stall 33kts, cruise 120kts, vne 150kts on 40hp.
They do need sponsors so if any with a few million to spare they would be delighted to hear from you, better bet than buying a football club or race horse.

Richard hello !

Here is one that uses 6,5 kW at 100 mph !

40 hp is then like 4 x too much power in the CGFC competition ( of course if they go really really fast….then maybe ).

I also know a french team that is going to “hop over the pond” at 8,0 kW at 150 km/h.

Luciole has 640 ccm B&S engine..like DA-11. That is still 2x too big in consumption for the race.

Doug,

Is that kinda aeroplane stable like the one with separate tailfeathers ?

I bet the Reynolds number figures are cool !

Best thing is the optimisation of the structure..that will be very lite.

Here is once more my possible entry for Cafe’s GFC race.

Anyone with experience ( in building one ) wanna join with risk ?

More about it in my blog.

Incredible Deskpilot !

I had suntin similar inbetween these here shown designs…partially lifting body I mean.

That is simple and cool !

Are you aware of the 1 650 000 USD CAFE GFC race ? Green Flight Competition is on its way…maybe you will attent ?
