Zonsen Aero Engines - Rapture Aviation (Adelaide)

[Rapture]

Please guys. Going off topic will really devalue this thread for folks actually wanting good information about the Zonsen engines and installations.

i shall respectfully ask an admin to moderate this thread to remove junk. Please start your own threads for sidebar conversations.

Our prop spacer arrived a couple of days ago. Now we can really make headway with the mount.

Hi Rapture,

 

"Our prop spacer arrived a couple of days ago."

 

Aside from the obvious,  moving the prop forward, what is the purpose/benefit of having a prop extension in this installation?😈

 

[Thruster88]

The obvious would be to move the engine back to help with CoG.

True!

However there are sometimes other reasons. Its not unknown for aesthetics to be one, air flow, prop clearance (nose wheel), etc

 

What weight is the Zonsen (?) compared with the origional Jab?? .😈

Another possible reason is to retain the original cowlings and reduce cost.

He did state that earlier in the updates, plus being a heavier engine it needed to shift rearwards, hence the spacer.   Savannahs have much longer spacers.  Great Idea and have seen two R Jabs and owners happy with them and they would have excellent w7b and mod info.  I can't wait to see it flying and being a fairly straight forward engine brand swap under existing cowl.

I've done a lot of prototype work. If you have the manpower and a simple thing like this is holding up progress it may be better to knock up a dummy one. Perhaps an hour or so for a good guy to produce a correctly dimensioned dummy allowing you to continue with other work. A couple of endplates welded to a suitably dimensioned tube and dressed in the lathe for accuracy should do the job.
