Have read multiple places that the 912 gearbox needs to be run at an RPM above idle when landing and during taxi to alleviate wear on the gearbox. I gotta admit that fact alone boggles my tiny brain as an engineer. Why wouldn't Rotax fix that so that their engine could be operated 'normally' like most other aircraft engines. Wonder if the 915 has the same issue since there is more torque and HP. I have also read that Edge Performance has done some work/modifications on the gearbox with regard to their 912sti version. Anyone know if their engines can be run at idle on approach and taxi?

Am starting to wrestle with what engine I am going to use and this is one of the questions I have.

Thanks for any input.
