This is very good what is being done in the 4 th generation. Having all aluminum cylinders works great, Harley Davidson has been doing this for years with total success.
I am looking for ANY information I can find on the Jabiru 2200 Calypso. Does anyone have any first-hand knowledge on this aircraft? Is it suitable as an ab-initio training aircraft? Can a Rotax 912 be put in it? Do I understand correctly that this aircraft has a 25 hour oil change cycle??
Harlow Jan Picart I can tell you the self destructiveness potentials of the 2200 in 400 hours or less. 10,500 dollars later I now own a used 912ULS with more horsepower and some peace of mind. PS I also have a Jabiru boat anchor for sale, in the shape of an pathetic airplane engine.
That is NOT the whole story! It was a very political decision. I would advise getting the whole story. We did a video on it which you can use to get more information. The Ultralight Flyer
Light Sport and Ultralight Flyer Everyone knows Rotax needs competition but the aviation authority in Australia did intervene. If you have evidence to explain why, make it available and provide a link. "It''s very political" is just one step short of "it's fake news!"
They are direct drive and turn about the same as other 4 stroke engines like Lycoming and Continental. If you were able to install a redrive and reduce prop rpm, you would have to be spinning one hell of a long prop to get the thrust equivalent! The Ultralight Flyer
What RPMs are you working on Ray? Are you sure you are not confusing the Jabiru with the Rotax 912 series engines? Jabirus are direct drive (max 3300 rpm) rotax 912s have a reduction gearbox (max 5800 rpm).
@@spency787 3300 rpm is too high for direct drive, when experimental types are flying around 100 knots and looking to swing a 76 inch (or bigger) prop.
These are nice, but the MYT-6 engine concept is a better design, 200 HP and under 30 lbs, very few moving parts and with lubricating fuels it never needs an oil change.
Vaporware... sometimes things look good on paper but have materials science problems due to engine stresses.... the MYT is probably one of those. Another one with that type of problem is the liquid piston.... it may eventually work but it due to the mechanical stresses on the engine it will require alot of materials science to make an engine that can survive the stresses placed on it without wearing or exploding. Engines like VWs or Jabirus are very slow stress engines you can build them out of low quality materials and them usually not explode when built with high quality materials they are could be made very sound and reliable.

Changing to a casting from a machined-from-billet must reduce costs, but loses that sculptural beauty of the machined part.

agree completely.
Waterworld 360: The MYT-6 "engine/motor" is Vaporware, isn't it ? Do you have a link for us ?

Turn the oil filter 90 degrees - its a mess to do oil changes. Also Needs more output from the alternator... and EFI :)
What is the propulsive efficiency of Jabiru 2200 propeller sir?

They had to! The Australian aviation authority came close to grounding the entire Jabiru engined fleet!

And they took your guns away too
@@mrbradgeary no they didn't, just made a few hoops to jump through to get most of what we use.
I just wish Jabaru would cast mounting bosses on there motor block so a reduction drive could be used when desired. There RPMs are too high for me.

So you make a good engine and then set yourself a task to reduce costs…! Sounds like a recipe for disaster to me.
