Rod Torr [ Brizy ] has sourced right angle drive gearboxes that he believes will be spoton for gyros.
Cost around $700, plus bracketry etc etc.
Estimated fitted, up and running, 2 grand per machine......[ complete ] there abouts. Sold in Brisbane somewhere.
Speed............yet to find out, one is going on my build.

Sorry Russ,

Am I miss reading this...two grand for a pre-rotator?

Mitch

Mitch when your after the last 50-100 rrpm it will cost you, that be about on the money, a RAF one will cost about 3500 USD about 5k by the time you get it in the country, great tax system we have and all.

Hmmm!

Leave it with me Bones......Ive been told the MLS being prototyped now for 503 rotax should give around 250 rrpm.

I know on the Monarch 582 it delivers 325 rrpm for a less than 10 mtr takeoff.

How many rpms do you want in that last 50 or 100?

Mitch.

IMHO machines with cabins, and some other machines with great pre rotators, should have noted in the POH that the machine is not to be flown if the pre rotator is not working.

Pretty pointless teaching hand starting, slowly building up RRPM etc to someone who will never have need to use it, and if they did when the pre rotator broke they would be so out of practice. Pre rotoator failure does not occour very often if at all in my experience.
