Title: Flying a fokker dr1 question
Post by: Gregor77 on April 15, 2011, 06:40:24 AM
Can some tell me how to properlly set up the aileron rudder mix?  If I turn right with the alerions,does the rudder need to go right or left?  I think left to keep the plane from banking?  Anyone know?  All the forums say to add 20% mix on rudder.

The rudder needs to go right as the ailerons go right (right aileron up).

This helps the tail move in the proper direction, and helps prevent a stall from the drag of the lowered left aileron.

Aileron - Rudder mix: rudder turns in the same direction as the aileron.

Looking at the plane from behind. (just in case of confusion  ;)  )

Would setting up some aileron differential accomplish the same thing?

I believe you can mitigate the adverse yaw with differential aileron as Greg has suggested.

Re use of rudder to achieve coordinated turns, I believe aileron and rudder coordination (both in same direction) only applies to upright flight.  If you are inverted, you use opposite rudder to coordinate with aileron.  So, mixing in rudder permanently would limit you.  I would simply fly it the way you would fly the real thing, manually.  Any other thoughts on this from the group?

Thank for everyonrs help.  But after glen tried it out, I took all the suggestions from rc groups and all other forums and removed the mix.  You guys were right.  Much easier to fly if doing it manually.  I reduced the throws on the ailerons and it was less twitchy.  With glens set uo it is much easier to fly.  Althought still a handful.  Looking forward to get more time behind the sticks.  Looks great in the sky.

Here are some images from Simon.  We had a chance to try it out.   Now moving to a 2209 Bell Motor to get 180 watts of power.  This will help reduce the 3/4 throttle just to get it flying.

Got to say, the DR1 looked great in the air.......I remember seeing a replica at an airshow about 20 years ago, and Greg's looked just like it.

Hm, maybe I now need to scratch the bi-plane/tri-plane itch?

Better be careful. There's an SE5a on the horizon ...
