I have 3 BME 116's in my fleet. they are a great engine.

Pro's
A lot of power and great spoolup.
Very light
Very good quality

Cons
Attention must be paid to baffling cooling airflow over them (as we should do with all of our engines)
Tuning needles point forward so you need to shut the engine down to make adjustments
Exhaust flanges are not "DA" pattern so you need to source the header flanges (They are readily available in the USA)


They prefer slightly higher RPM's than some of the competition but they outpul most of the competition when allowed to run. I am experimenting with props on a 3D plane (108" Yak that weighs 10.75Kg / 23.5lbs all up) at the moment and am finding that 27/10's work well in the higher load props (Biela, Fuchs etc) and 28/10's in the lighter loading props (Xoar etc) I do have to be cautious about prop ripping when using those though.
