开云体育I wonder if a 90 hp "Viking 90" motor (stated weight 72 kg) or an 85 hp "Aeromomentum AM10" (63 kg) could be considered?

I have an X-Air F? ( Falcon in the UK ) with Rotax 912 and it works very well.? Performance is no greater than a 2 stroke but much greater reliability. Theoretically it should use less fuel but mine burns around 14 litres an hour. Previous owner said it burnt 12 litres an hour . The difference might be because I fitted heated carb bodies when I bought it to prevent carb ice. If attachments work there is a photo of the engine installation attached.? The Engine mount is special for the 912 and the forward engine struts are shortened. There are some weight concerns. Mine was the development aircraft and has lightweight wheels, floor and originally had a smaller single tank. It now has double tanks ( 55 Litres )? and as I fly alone a long range tank with another 20 litres, so now aircraft endurance is far greater than pilot endurance !! - more than 5 hours. In the UK there are a couple flying with the D-motor which seems an interesting combination.? The only thing I don't like with the 912 is flying with high revs ( cruise 4800-5000 rpm ) which makes for a noisy cockpit although a recent Bose A20 has improved the situation. The D-Motor , like the Jabiru flies with half the revs so would be more comfortable but for me reliability is the No consideration.? I like the D Motor but would want to wait a few years to see how the reliability is before flying with one. Regards, Jonathan On 29/07/2022 10:13, Michael Coates wrote:
Too heavy for the X-Air Standard....??? They own the X-Air Airframe as their test bed but cant use it because of the weight etc....???? However it looks promising ! |
