[NSRCA-discussion] 1985 Nats

[davel322 at comcast.net]

MK made a spinner and propeller assembly that used an extra servo to adjust the pitch of the propellers.  A Pmix between the throttle servo and pitch servo was used to flatten the pitch at low RPM (better braking) and increase pitch at higher throttle.  As Ivan said….pricy….and added substantial weight (5 or so ounces) at a time when most F3A planes were 8 lbs +/-.

 

Regards,


Dave

What were the variable pitch props Ivan was talking about in the video? Seems like an interesting concept.

Xavier, Nice find.  I flew in Advanced that year and was just looking through those pictures in my photo album.   

 

Great to hear the Chip Hyde interview-  description on the elevator to preserve geometry of the avalanche is right on. 

 

Ivan's advice on the six sided loop is still relevant today....

 

"Make the corners with authority, don't make maneuver too big, and the (F21- half 8 sided loop with two half rolls) becomes much easier to do..."

 

 and Dean Pappas discussing the finer points....

Dave Lockhart found the old EU-1 series Dean referred to... https://www.rcuniverse.com/forum/classic-rc-pattern-flying-379/10860066-rules-history-eu1-pics.html?styleid=7
