The International Cessna 170 Association

Finally got around to making this. Created a makeshift fid with a metal punch and tape. Seems to work great.

Success! LOL

Yes, the 170 is a challenge when it comes to securing the rudder. If you walk around the flight line you can usually find a 170 (or similar type) with damaged rudders and rudder-bellcranks where they've been beaten against the stops. Using the top of the rudder to slip a "pad" between the rudder counter-balance/horn and vertical stabilizer is another sure-fire method to KILL the rudder, because a wind gust will bend the rudder counterbalance.

Glad to see your Success! Congratulations!

I came across this gem on Ebay. I wont be able to fit it until i buy the airplane but for now its safely stored in my treasure box.

Has anyone seen this before?

I had a Cub with a stick control lock similar to that.

This appears to go between the rudder bellcrank and the top portion of the tailwheel. We’ll see.

The series “6” PN leads me to believe this is for an L19/O1 BirdDog. Maybe slips over the stick and against the rudder pedals.

p/n is 1600101-1
Now you just have to figure out how to convert the 170 from a control wheel to a stick. That would be a cool STC!

That’s an “8” series PN drawing which applies to the Agwagon.

I'd buy it in a heartbeat! About the only improvement you could possibly make...other than a bigger engine.

I just made one and it works great. Local shoe repair store took the outline I got from this site and made one, $12

Thanks for the tips and outline!

I find aircraft with Sticks much harder to enter/ egress and love the 170 for their ease of doing both.

Flying a Cub/ Super Cub/ Champ are fun but getting in/ out is gymnastics. I'm too old.

Agreed!! I did my flight review in a Super Cub last spring and it convinced me of the wisdom you expressed.

I thought some may be interested in a solution I came up with. Maybe someone can improve upon it. Here's the picture: Specs:
1) Locks both rudder and elevator, at their trailing edges, while also cradling the aft 10" of each surface at a rib.
2) Eliminates stresses on control system.
3) Cradles the rudder just above the position light, so will also work with tailBeacon equipped aircraft.
4) Lighter weight than PVC based designs.
5) Padding is cheap and easily replaced plumbing insulation available from most hardware/plumbing sources.
6) Positively held in place by dual, redundant bungee straps.
7) If one forgets to remove, the lack of tailwheel steering should make the oversight obvious to the pilot while attempting to taxi.
8] Can be disassembled and collapsed for storage (total weight: 3.5 lbs including bungee straps.)

This will NOT fit the 170 or 170A without design modification.
