All good aircraft, no bad choices. My criteria would be to get the type of aircraft that is active in your area. Having a group to fly with will increase your enjoyment immensely.

'87 Yak-52, standard M-14P and V530 prop, ~ 970 TT.

Level flight, solo, at 6500' MSL, 610mm and WOT, pull prop lever fully aft and prop speed dropped to 66% but would not decrease further. Stabili ...

Hey John.

I have done this process 4 times in the last 6 months when my overhauled engine had to be removed for the second time.
My mechanic came up with a perfect solution. Take a long, stiff str ...

Mounting the back plate is a slow and agonizing process, there is no way around it, only different recovery techniques. An easy chair and cold beer is often the reward after each nut is put on. Did I ...

So I went into the parts catalog because it appeared there was another ring to be removed, and I was right. It is called 'removable ring' in some illustrations and is the ring the bolts that serve as ...

Mechanic asked for some help, installing a new-to-me spinner (Yak-18T style), and we are having trouble getting the nuts on the back side. Removed the beauty ring that sat over the inner gill frame o ...

This A/B changeover switch was used with the preconfigured ADF frequency pair settings (A & B) as selected by the cockpit ADF pair numerical rotary knob.

It was (is?) Russian practice to place ...

Curious what the stock function of the Changeover Switch mounted under the glareshields, right hand side is? Can't find a description in basic manuals.

Anybody know if the CJ emergency air bottle is interchangeable for a Yak-52?

Thanks

Not directly Yak/CJ related but since we have a good RPA community up there figured I would ask here.

A friend is looking for a contact at Scottsdale FSDO to begin the process to become a DPE in Pr ...

Bumping for another attempt in case question isn't clear enough.

Is there a way to increase friction on the prop lever only, either external to the quadrant (maybe some drag on the push-pull cable ...

Just bumping this in case it got missed in all the message traffic.

Curious if others have had the prop lever move too easily without friction on and if so, what did you do to keep a prop setting w ...

UPDATE - got everything put back together, went surprisingly well. Did a leak check with soapy water by pulling a few blades through and saw bubbles, so tightened the check valve to compressor fittin ...

Also do not forget to someday soon run a complete compression test on the engine and to verify valve lash is set correctly. An eroded exhaust valve? Possibly. Hope not.

I do occasionally have a stumble on Mag 2 during run-up check that I had chalked up to occasional plug fouling during extended warm-up periods, usually clears up after a brief ...

Got the compressor off, it was the shear coupling. Verified compressor itself is still healthy (turns smoothly and pumps great). Also verified gasket installed correctly and in great shape.

1. You're not running auto gas are you?
2. What kind of plugs and wires are you using?
3. Check the timing. Even though you are shutting the mags OFF, ought of whack timing impacts plug ...

Mark, I'll get back to the kick-back issue shortly.

I have all 6 bolts off and the banjo disconnected but one of the guys has mentioned recalling a sleeve or something between the compressor and th ...
