Update:

Covered the base of the pedal, spring and all, with rags soaking in water, heated the vertical tubing full length to just under glow temp, then bent (read straightened) it. I now have...

Nothing but praise for Airframes, here.

Looking at the geometry, I'd say repeated fore-and-aft bending forces acting on that fitting are responsible. In pure tension, it should be able to take far more punishment than a 100,000 survivable...

Disconnected the cable and took a couple new pics. The pedal is canted outboard all right but twisted and possibly bent. Judging from the twist (the outboard arm of the T is forward of the inboard)...

That's a great shot. Thank you. Looks like the T should clear the flap ratchet pawl laterally by about 1/4". I'll check the pedal geometry and alignment. Something's definitely screwy. Just hope I...

Cable is already at the shortest holes, John. Don't want to make new cables if I don't have to.

Thanks, Greg. I thought so.

It's an -18AS-150 w/25deg. rudder travel. Here are some pics, w/...

Has anybody seen the left rear rudder pedal T fouling the flap handle anchor where it attaches to the seat? If so, what's a good fix (other than shortening the cables)?

The mags are timed to the engine to fire at 25* before TDC. The impulse coupling retards that by about 25* so it will fire around TDC during starts. If your prop is horizontal when your #1 piston is...

Make sure you get the right axle sizes for your wheels. They come in 1-1/4" and 1-1/2". You might need new axle nuts too (they're not cheap).

The L-21A Erection Manual (p.72) says turn the crank so that the right front cylinder is at TDC then install prop so it's horizontal. I think it's a balance issue with the O-290 - not sure if it's...

Good point. I stand corrected. Thanks. Having reread the original post, it's clear the diode was between 12VDC and ground, NOT 12VDC and the + terminal of the coil. Diodes are sometimes stuck there...

Something to keep in mind is that the dropout voltage is 4.5V (at least on Lamar's 12VDC relays). So even if your master switch is ON, the relay will (should) release well before the battery gets...

Raw design data is data obtained by punching in design criteria into a computer that already has a complete database of all the laws an airplane is subjected to. The computer spits out a design that...

Up here upset recovery was (is?) part of the PPC. The exercise was conducted in black air but with motion OFF.

Don't know much about sim s/w, but I believe all newer generation boxes use the raw...

Don't know the 330, but I can't see why it would be unrecoverable from 25,000' if its flight controls were working. It has generous wings and a long fuselage, and it's at those altitudes...

Enjoy it while it lasts, Wayne!

... Unfortunately, accidents and incidents continue to occur with airplanes carrying external loads. In October 2003, a fatal loss-of-control...

You're welcome.

As far as I know, flight control force requirements are a function of control surface area and deflection, and air density and relative movement (IAS) - besides other factors such as shape, material,...

Are you asking or enlightening me? If you're asking, I'll try to answer best I can.

Them parasite weights trap water, ice, dust and sand and conceal stuff you want to see/service on your walkaround. Don't have 'em; don't want 'em.

You're saying "too large forces to muscle." Forces required are proportional to weight - all else being equal.

They would definitely not love to do that. Hydraulics especially when fly-by-wire...

Fact is airplanes 10 times the weight of a C-46, 4 times that of a DC-9 have been flying with manual flight controls for over 50 years. It's only a matter of designing adequate mechanical systems.

Boeing, McDonnell Douglas, Lockheed and others understood that airplanes are supposed give man the ability to fly, not the other way around. They design dependent systems, airplanes, to complement...

Not the first close call. Now the police forces have them too for "crowd control"(?!)...
