[NSRCA-discussion] Masters Set-Up

[Nat Penton]

Just thinking out loud. Torque tends to make the airplane roll left. Torque aero effects are max at full power and low airspeed ( vertical ). We normally trim ailerons for one airspeed and the choice is  S & L .

Based on above the airplane should roll right when you take away the torque.             Nat

  I glanced through it...about throttle to aileron mix section. My experience has been the opposite. I've always noticed the airplanes roll slightly to the left (not right as the article states) when throttle is reduced.  I've flown many different sizes, including  .60 size, 2 meter stuff and some big IMAC machines. Even flown quite a few of other people's planes (some more than the owners flew themselves J, all built really well by talented modelers & builders. All rolled left, not right..Torque wants to roll the plane left when accelerating, the slip stream/pitch factor wants to roll the plane right at speed, which becomes the dominating force at or near full speed, so we carry left aileron trim at full throttle, when we throttle back, the left trim now takes over and rolls the plane to the left..In short, right aileron needs to be mixed with low throttle.

  Hi Jim,

   

  I would like too add to that reading material an article written by

  Peter Goldsmith regarding trimming seen here:

  http://www.mini-iac.com/DesktopDefault.aspx?tabid=70

   

  Peter's article is on the far right side of the page under "special"

  articles.  This is on of the best trimming article I've read and goes a

  little further than a list of tests to perform.

   

  Thanks,

  Jim W.

  Hi Jim,

   

  If you haven't already, I really recommend going through these trim

  instructions with your airplane:
