• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Hey all!

I'm the new owner of N9QT, a 50th anniversary Pitts S2B (any previous owners out there?).

I just flew the airplane for the first time yesterday after my ferry pilot took it most of the way across country from Memphis to Northern California (it's now based at Gnoss field in Marin County). There are a handful of minor bugs to work out with the airplane but the big one is that the propeller lever is nearly impossible to move. This airplane has The Claw on it. It feels like the prop lever is sticking to the nylon ring where the rod goes into the panel in the back cockpit, but that doesn't seem like a spot that would have as much friction as I'm feeling on it. We tried some silicon spray and it made it a tiny bit better, but it's still terrible. It's almost un-flyable like this; you have to kind of wiggle it to get it to move the small amount you need to adjust RPM - if you really pull on it, it'll suddenly release and pop-out way too far. Come to think of it, the throttle cable is pretty stiff, also.

Anyone else seen or fixed this? The exploded diagrams don't tell me much. I'm hoping it's not an issue with the actuating arm on the governor, but who knows at this point.

thanks!

Hoagy
