Hi Stuart, drive ratio is determined by turning the input shaft 10 times, while counting output shaft rotations.Divide result by 10. What was your redrive used on, and how do you come to be on ez.org? Sincerely, Robert

I'm curious why you would want a 2.17:1 ratio if it were to be on an EZE. Unless you are running a large propeller or a high revving engine (Mazda) the 2.17:1 ratio will cause a slow prop and either poor take off performance or poor cruise performance. If it's not for an Eze then forget my remarks.
Regards
Phillip Johnson

Hi Phillip, no, that's a fair question, I am running a 13b Mazda, which I like. I have been able to easily overspeed the 3 different props I use, including the Ivo Magnum, which I liked,as it tracked well and was almost as smooth as my Lydick prop and would drag my tires on dry pavement during runup, but lacked pitch for my application.
Now going to a bigger club and taller gears. Think I've got some engine pics on my profile.
