REFLECTOR: Door strut review

[nmflyer1 at aol.com]

Scott, 



Ran that by the factory as well. I do not know if there is a difference in that area between a FG and an RG. They said to go up 2" only, no more!  I believe if you go more, you wind up with the thrust line above the elevator, effectively causing a plow. I wouldn't change something like that without running it by the "pros".  :)





I do know of one V-builder that moved his thrust line up almost 6" to accomodate what he had planned to do... he took TONS of runway even with a high HP motor.

I didn't know FG's were taller? 
You moved your thrust line?  I was cautioned about that when installing
he 520.    Interesting to see how that will effect performance?

 Scott,
  
 Miracle grow :)
  
 Honestly, since I have the FG version, it is about 2" taller than the
 RG already. Then, on advice of Scott S., I moved my axles down about
 an inch. (Some of the bottom of the gear leg gets ground off anyway).
  
 I also moved my thrust line up about 2". Those adjustments allow me to
 swing a 76" 3-blade CS, with the recommended clearance or a tad more.
  
 Sure seems taller than that when I see others on a ramp though.

 Kurt,

 how'd you make it taller?  I thought about doing that when I built new
 main legs but the blanks are only so long?
