EVO 90 (USA)
I recently purchased an Evo 90 (USA version) with the 8.45 ratio. If this machine was designed for the USA 3D pilot with most of them using OS 90 size engines when the 7.92 ratio suited to the OS better?
Can anyone please explain this or is it a scam from MRC

No scam. At the time the bird was released, OS engines were not running very well nor were they available. Most pilots were running the YS and 8.45 is the happy gear ratio for that engine.

Some guys use OS SZ-H´s in their EVO90 w. 8.45:1 to ratio.
Not sure how a CSpec would like it though.
