Vectorflight Extra 300S Throws
 

The manual for the 300S gives the throws to start with on the control surfaces, but where do you measure? It doesn't say weather to measure at the narrow part of the control surface, or the wide part of the control surface.
What have those of you who fly this plane used for control throw deflection?

Without using a throw meter you can take a standard ruler with the inches on one side and mm on the other and place it upright against the trailing edge of the aileron closest to the fuse. Move your aileron gimble to it's full deflection and you can see how far they are traveling. It's easier done with a friend helping IMHO.

The question was weather to set the total throw measuring at the top/bottom of the rudder, or inside/outside on the elevator. Both control surfaces are wider at one end than the other.
The amount of travel isn't given in degrees, which would make it much easier.
Example...If a rudder that were deflected to 30 degrees in both directions, and the top was 1" wide and the bottom were 2" wide, the top would travel 1.14 total and the bottom would travel 3" total. This is why it is confusing when the travel is given in inches.
Thanks for your input, but I am quite familiar with setting total throws, as long as I am told where to measure it from on a non-parallel control surface.

I put my 300s 66" together last summer and if I remember I used an incidence meter set in the middle of the elevator span. I fly on high rate elevator and it works fine--never had a problem with snapping at any speed. I probably set the rudder the same way and have no problem holding knife-edge flight. I do not have dual rates on my radio for rudder.

This plane flies where you point it and I doubt if a small variance in the settings will make a noticeable difference for sport flying. THis is my favorite plane and it will probably be yous too.

I just found my instruction sheet.
It says to set the throw at the widest part of the control surface.
Thanks to those who replied.
