Default Changing rudder pedal position

Hi folks,

I am looking at buying a used 8. The rudder pedals on the one I'm looking at are much too far aft for my leg length and I'm wondering how big a job it would be to move them forward. Best guess is they would need to be moved about 4-5 inches forward. (This 8 does not have the adjustable pedal option.) Thanks for your input.

As far as I know, all 8s have adjustable rudder pedals. Some are in-flight adjustable and some are not.

I would estimate 2 hours to make adjustments to the ground only adjustable rudder pedals.

PM or email me your email address and I'll send you DWG OP03, that shows the "ground adjustable" rudder pedal setup for the RV-8. It will give you an idea of what it takes to move them.

One thing to check is if there are individual reservoirs on the master cylinders. That is a popular mod as it eliminates a potential source of fluid leaking.

If so, then you could find that moving the pedals forward allows them to interfere with the firewall obstructing the rudder travel.

The solution to that would be to have a single reservoir mounted on the firewall, which is the standard arrangement. Other than that it's a straight forward job that should take less than an hour.

My 8 has ground adjustable pedals.. I would prefer as far forward as possible but the last position has the pedals hitting the firewall at full travel leaving no room for brake application in this position.. How have you guys resolved this issue?

Have you tried shortening the rudder cables by adjusting the nut on the firewall rudder cable anchor?

I haven't.. I just installed the links to move the pedals forward. At this point, I barely fit in the airplane (6'5" tall, 275 pounds). I've ordered the tall pilot option and will be moving the seat back about 1.5" soon.. The forward most position on the ground adjustable pedals would give me more room for sure. I'm told this is a known issue with the RV-8 ground adjustable setup..

I use my ground adjustable pedals in the full forward position. The pedal hit the firewall if you had full rudder and full brake at the same time before I put the brake fluid in, but haven't since. The resistance from the brake keeps it just barely clear.

Regarding the op, it is pretty easy to move the ground adjustable back, maybe 1/2 hour or so. Much easier if you take the forward baggage compartment shelf out and do it through the baggage door.
