Hi Paul, thanks for the info. You're right, I do like the tailwheel. I had a chance to fly last weekend and try it out. It works well, looks good, and doesn't cost a fortune.

Hi all, I recently replaced the Scott 3-24B tailwheel on my Chief with an Aviation Products Inc API 6131. Before I fly it, I have a question for someone with the same setup: Full rudder deflection puts the tailwheel in full swivel mode. Is that the way it is supposed to work? The Scott wouldn't swiv...

Thanks Paul and Bo. Quite difficult to diagnose engine problems by You-tube, but I appreciate the effort. I check torque on the prop bolts regularly, most recently earlier this month, so I know the prop isn't loose. I found this from Continental guru Harry Fenton: "I never really cared for the ...

Hi All, I own a Chief but for various reasons haven't flown it very much. And now that prime flying weather has finally arrived in the Pacific Northwest, and the airplane is finally in one piece, I'm perplexed by an engine issue -- it has a noisy idle; a sort of regular "clunk" that seems ...

I should have said that differently. Using a recorded tone to gauge brace wire tension may be a little iffy in practice -- although the principle is sound.

I believe you need to use a flying wire tensiometer. Something like this: http://www.hangartoolbox.com/Tools/23.aspx . There are probably other ways to do it - maybe use a spring scales to measure the force required to give a certain amount of deflection. Relying on a recorded tone seems really &quo...

Hi Paul, thanks for the feedback. I like the idea of installing a sleeve with a cotter pin to extend the rudder stop. Sure beats trying to weld on an airplane or rudder that's already covered. I'll leave the rudder straightening and fork replacement for another time if I can get through the annual i...

The pedals are definitely too far forward, I expect caused by rudder cables that are too long. Univair is making up a new set to the length specified in the drawing and I expect this will solve that part of the problem. The over-travel to the right is due to the stop pin on the fuselage being too sh...

Elevator travel is within specifications of 26 degrees up, 24.5 degrees down. With the control column forward, left rudder is at the specified 28 degrees, but limited by contact between the rudder pedal and torque tube and by simultaneous contact between the tailwheel steering arm and tailwheel leaf...

I discovered recently that I am not able to get full left rudder deflection with the control column full aft. The rudder pedal contacts the aileron pulley bracket on the column and limits the rudder to about 3/4 deflection. I've set the adjustment plates for the shortest length possible. I suspect t...

Jim, I shipped the hub today. I will send a PM with the details.

Jim, I can send the hub tomorrow. FedEx ground with 5 business day delivery is about $14. Is that ok? Payment ($100 plus shipping) due in 30 days. That should give you time to get it inspected/magnafluxed and decide if you want to keep it or send it back. I am not representing the hub as being airwo...

I am not able to attach the photo. I'll try sending it by pm.

Jim, the hubs show up several times a year on eBay and sell for $150 to $300. Also refer to the post on this bulletin board from Classic Aero (Doug Combs): "propeller hub, continental tapered, 65, 75, 80, 85". Attached is a photo of one I bought on eBay for $175. Look carefully at the snap...

Wag Aero has the 2-738 for $46.15. Page 18 of the Aeronca catalog.
