[rebel-builders] rudder pedal return springs
Posted: Sun Feb 19, 2012 12:11 pm
Hi Jesse !
I think the springs are just to hold the pedals vertical !
There is a fair bit of weight & friction in the cable - as long
as they are strong enough to overcome that, you should
be OK ....
Maybe you do need longer and/or weaker springs.
Probably better than changing to a more vertical angle,
although there's nothing wrong with going to the
rear of the engine mount, as long as the spring doesn't
obstruct pedal travel.
Might have something to do with how far back you
have positioned your pedals. I've seen many Rebels
with the pedals too far forward ! In that position,
if you push in full rudder, plus full brake, the pedal
is hitting the firewall, and you can't get full brake ! :-(
This is one area where you can customize your
airplane for comfort - with the pedals farther back,
the airplane can be comfortable for shorter-legged
pilots, and still work well for others, if they like to fly
with their knees bent....

If I attach my springs as shown in the manual (toward the front of the
engine mount brackets) it will put a huge pre-load on them. I don't think I
want that much tension in the system. It looks like a more vertical
attachment to the bracket would work better, because the tension increase
won't be so linear as the pedal moves aft. What happens if a rudder cable
breaks? With a ton of tension on the other side, you get a rudder
hardover=bad. Do you want just enough spring tension to hold the pedals
vertical in the neutral position, or should there be enough to pull the
pedal to the forward stop? If the latter is true, it sure seems that my
springs anyway, would be pulling pretty darn hard with the pedal at the aft
stop.
Should I get lighter (weaker) springs that have more travel?
Thanks.
Jesse
