Its been happening.  They are too long and the steel doesn't expand as much as the Alloy. It's not an uncommon problem in such designs. . Be interest to have my question answered.  Nev

Give it a rest Nev.  Another completely unsubstantiated sweeping generalised negative comment from you about the 912 series.

The cylinder fins look turned 90 degrees to the air flow and looks like the coolant jacket extends under the head onto the upper area of the cylinder. very different to the lower hp version I've seen reviews on.  Thanks for post.

The 110hp CA510 has no Rotax equivalent. It is fully water cooled, and does not require any air cooling of the heads etc. This explains the different architecture of this model.

Not made up at all,. But carry on IF it makes you feel better. Do your own proper research if you really care. Nev

Every time Rotax is mentioned you say how badly designed they are and all the problems they have.

Yet no one else has much trouble with them. Yesterday I was talking to my instructor about aircraft and he said 912 are bullet proof. He has thousands of hours behind 912 uls and has never had an issue.

I critically examine  many aircraft engine in dept and they ALL have some design Faults No engine is bullet proof particularly piston engined ones. Rotax later motors are becoming more highly stressed and complex.  People say Merlins were a great Engine and the highest TBO ever was 650 Hours .

  My comment wasn't generalised. It was related to the LONG studs holding alloy bits together that get Hot and expand at different rates.. Nev
