I just want to make sure I have this right too. I moved ATV's to 140%, moved the rod in on the servo side and the rod out on the control horn. I am getting a little better than 1.5 to 1 advantage. If I am still getting too much throw on high rates, do you just reduce high rates until you get to the proper throw? same for low rates? Thanks!
ORIGINAL: sillyness
So I fix it set it up and have been told to run the atv all the way to 140% and set-up the linkages for maximum mechanical advantage which I have, but now I want to tune down the throws. How do I do this without changing the geometery at the servo?
OK...
Set ATVs to 140%
Adjust mechanical setup to get the MAXIMUM throws you will ever actually fly with (about 32-35 degrees for me).
Use Dual Rates to adjust throw down for IMAC.
The whole point of this exercise is to get the control horn as long as possible and/or the servo arm as short as possible. NOTHING else will actually change the power the servo has.
You WILL get better resolution, but your servo WILL also get better leverage on the surface... this puts less load on the servo, requiring less torque.
Ideally... I look for a 1.5:1 ratio (1.5" control horn to a 1" servo arm, or thereabouts). My setup actually has a slightly better mechanical advantage than this.
