I have a std Vigor and had a few questions?
First, What is the correct gear ratio to drop a 90 in it?
Second, What are the largest blades I can run?
And lastly I was thinking about upgrading the servos, what would you reccomend? I was looking at getting 3 DS8717.

Gear ratio

If YS90 then 8.4:1 (84 main, 10T pinion)
If OS91 then 8:1 (88 main, 11T pinion, some trimming of engine mounting required)

Speaking of gear ratios, what would be the best gear for a Vigor cs powered by an OS 70 and swinging a scale 5 blade head?

I'm guessing somewhere in the 1300-1400 rpm range.
