All are good points however finding a non arrogant, professional LAME or L2 with in depth real current knowledge on all variants of Jabiru isnt easy.
That manual flap mechanisim is pretty ordinary even when new. Sure had a few frights with it releasing from St 2 to 1 on short final, not only in terms of aircraft performance but the loud bang it makes.
Ive seen numerous attempts to improve with limited success
Get rid of it and fit electric version, if you have wings off it can be mounted pretty simply. Worst failure mode you have ten is flaps that wont come down or up, in either case you can handle it.
