Go to MARAP. jump thru required hoops, fly aeroplane

Now my Jabiru / Rotax project is nearing completion there is a matter I would like to correct. That is the C of G. placement. Jabiru say that the forward limit of a (at MTOW) J160 should be 233mm behind the wing L.E. After I had the weight and balance done I see that the C of G is at 217mm behind the L.E. the question is How much weight do I add at the tail end to move the C of G 30mm rearward. I have all the calculation values at hand , I just dont know how to calculate the value. Weight 2.pdf weight 1.pdf

I'm going to be taking a J230 to Caboolture from Melbourne as soon as weather permits. Can anyone suggest a suitable route? Stops for Mogas would be good but not critical. Thanks, Geoff

I have a rotax (aviasport ) tacho that reads just fine up to 3000 rpm then stops going any higher. Any ideas? Anyone one know of any new stock in OZ?- 57mm. Thanks G

Thanks everyone. I have a couple of numbers to work with. Although I would have thought that RAA would have known who has the Rotax powered Jabiru's. The aircraft has an "Experimental" sticker on the side. I stuck the decals on in anticipation of E reg. When I try to remove them the paint comes off!!!

RE: Rotax/Jabiru 160C Well, things have moved along. The aircraft is finished and I'm on the road to MARAP. Unfortunately there is no other way. The weight and balance was done today. Empty weight came out a couple of kilos over the original 302, and the C of G is in the correct range. So things progress. AS the 160c is a Certified aircraft it has to follow the MARAP path. ( I really dont understand "Certified' and LSA, Why Certified? I can't follow it at all) I wish it were otherwise. I had no idea that the 160C was particularly singled out for this. RAA has been helpful so far. But, I WILL need examples of safe operation of a Rotax Powered Jabiru 160 There must be a couple around. Please raise your hand.

AH , OK , Then I will go down the E reg road. Thanks for the information.

I have just about finished fitting a Rotax to a J160. The RAA reg. Form (Tech form 14) requires that I identify other aircraft that have had a similar conversion. Quote"I have supporting documentation such as independent engineering advice or history of safe operation from elsewhere." Can or will anyone that has such a modification please let me know in the form of a statement that they have had X hours of safe operation? There is no liability attached to such a statement. Any information from anyone having gone through the registration of such a modification would be a great help, Thanks, Geoff Higgins.

Looking for an engine mount or a person able to make one for me. In Victoria , Rotax 912 uls to Jab 160. Brumby Aircraft have made some but only onsite in NSW and are unable to help. Drawing or Photos would be very helpful if I have to do it myself. Thanks G.
