The Rudder Crank Mod. 25

Aside from the enormity of the possible necessity of ripping out the 
recently reinforced floor panels, the knock-on effects would seem to in 
the way of moving the pedals outwards (literally !). As the pedal goes 
outwards, the forward travel becomes restricted by the permanent 
firewall.  If you accept your knees coming back some more, the mid-pedal 
position is no longer TDC. This means that a) total travel will be 
lost,(is there enough left with the crank in line with the fuselage frame 
?) and b) rudder action becomes differential, (rearward movement 
occurring at a lesser rate than forward). Is that ergonomically 
acceptable ? And for good measure, c) then the cables go slack (no 
replacement swages or adjusters supplied). Ugh ! Perhaps the factory will 
tell us what the unacceptable solutions they mention are, and why, one 
might be yours or mine ! Replacement pedals would save all this, but 
"cost to factory" and "builders time" have different dimensions.
