Nitro Engine. SH 18 Inch (2,74cc)
I will be trying a 2 stroke 26cc engine some time late in January. I will do some tests with it on the flying wing.

Put a large wood Prop on the petrol engine and did some tests.
idles without cutting out 30min test.
No longer overheats & prop is balanced.
Better thrust - but still unknown
Fuel consumption: Low RPM : 100ml per hour
High RPM : 300ml per hour
Will be able to get 10 hours of flight
Will also see if its possible to keep the UAV up for over 24 hours.

Engine and generator test. Working better than expected.
Still need to do a powered start from the generator
Regulated Nitro engine
Most nitro engines run incredible fast. They pump their exhaust fumes into the fuel tank to create pressure to pump the fuel to the carburetor. They are loud and can vary in rpm depending on G-force and other factors.
In this video I use a pump to regulate the fuel and keep the Nitro engine at low RPM. Hopefully this will assist in keeping nose down and reducing the fuel consumption.
