I think I have Revo set on a switch. When I use it it's around -20 on high and -15 on low. (don't have my Tx here, so I can't check) You want to set the propo on the tail before you work with the revo settings or it won't work right. I don't really see much difference, but I haven't really played with it to any extreme. As far as mixing, if the radio is on H-3 your mixes are pretty much set as long as your pitch rates and throttle rates are dialed in. The main thing that really helped me with the blade was expo. That makes the ail/elev much more controllable. Another thing, make sure you set the limits on the throttle to fit your 4-in-1. Mine is at 37%. What I did is set it low (around 30), move the stick to full (oh yeah, unplug the motors first), the increase it until the red light comes on. Then add 5%. Otherwise your red light will always be on over 33% stick.
