There has been a few posts talking about the costs of Lycoming services etc.
I am interested to know if there would be much difference between Rotax/Lycoming if you were doing all your own servicing and repairs (Excluding rebuilds).
Would the initial cost savings of a Lyc be eaten up by the ongoing costs when compared to the Rotax.
I have been assuming the actual fuel costs are about the same when you match performance between the engines.
I am ready to be shot down but one would think that it is roughly the same amount of fuel per HP, although the Rotax may be a little more efficient based on the given figures.
I have flown many hours in a Jab, a few as a pilot and many as a passenger, and am confident that the J430 airframe would do for the flying I want to do, which is multiday trips on the mainland and beyond, especially at 760 Kg MAUW.
The SP4000 drew my attention for it's carrying capacity and the addition of a traditional aircraft engine at what appears to be similar running costs, to the Jab when powered back to match it's performance. I also calculate the Lightwing could probably be built for slightly less than the cost of the Jab.
The only real concern is the ongoing cost of the Lyc, especially if something goes wrong with the Lyc.
I should also add that a 914 in the Jab would tick a lot of boxes, but would add at least 20k to the build price.
