As a tech, they would not have messed with the rigging. I’m confident it was like that prior to the ding. Mine are not exactly straight either. I think it does help the roll . Aviat MFG, on the Pitts and Huskys, some are over an inch off between sides in the balance horns. I wouldn’t worry about it. It would be difficult to put the horn on crooked. -Matt

During an oil change last year I found a broken cylinder hold down stud. Fortunately it wasn’t a through stud which I think would complicate the process of fixing the problem. Fixing mine required removing the cylinder and an interesting process to remove the broken stud piece that remained in the case - but was broken off below the surface. I’d imagine the fix for a through stud will require removing two cylinders. I would certainly contact the manufacturer for their input on the proper procedure for removing and replacing a through stud. Hopefully there is a precedent for doing so while the engine is still installed.

My KX 165 is not in a good shape. Options are to either refurbish the existing unit, replace it with a used unit that is in better shape, replace it with new KX200 or replace it with something else which would involve major surgery on the panel. KX 200 seems to offer the path of least inconvenience in my case if it is, indeed, a slide in replacement.

Is it the 720 channel or 760 channel version? The 720-channel -165 in the M20K I’m trying to get flying has seen some better days, so I’m looking for a 760-channel replacement.

Can it be integrated with Garmin avionics to control it? I have an old avionics stack and I'm considering cost effective path to upgrade while keeping two coms/nav radios. I don't want go full gps.

Given that it was not the same engine I felt it might go wrong… but no they accepted the [emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]]]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]]]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]]]][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]][emoji[emoji638][emoji639][emoji[emoji6[emoji640][emoji638]][emoji640][emoji640]][emoji[emoji6[emoji640][emoji638]][emoji640][emoji6[emoji640][emoji637]]]]]]] Sent from my iPhone using Tapatalk Pro

@jrwilson and @IvanP Curious what is motivation to replace a perfectly good KX-165 with a KX-200? A cursory exam of the KX-200 data sheet doesn't show much practical difference (okay, it stores 50 freqs). What am I missing?

I would ask the shop, taking the left elevator out does not require changing anything in the linkage, so first thing to ask is whether anything was adjusted in the left elevator linkage, if yes, set the elevators equal and see how that feels, overall I would think that the elevators should be equal, compensating for a roll imbalance by offsetting the elevators would cause excessive drag

Late to the discussion, gear then flaps.

It could be the case was fretting, or some sealant got on the case halves where the through bolt went through. This can cause a lack of stress (torque) leading to what you describe. Lycoming has a service bulletin warning people that the use of any type of sealant around the through bolts can lead to this failure. Some were putting sealant around the through bolts to stop oil leaks. Lycoming says that is a very bad idea.

Yes, a few years ago the supply of A&Ps dried up and the ones they had moved on. They still do a great job though just the scheduling is more difficult.

If it is not torqued to spec, or not torqued at all, it has low or no preload on it, it will fail in cyclic fatigue. That looks like maybe what we have here.

Lot of holes in that cheese.

I just opened the box today and am putting the 14V adapter on. Haven't used it yet. Looks fancy though :) Took 9 months to get shipped through spruce.

how many planes as UL94 totaled?

I wonder if Don maxwell ended up with the wood spar also that was sitting on the floor of the delivery hangar @Dmax??

No recent work, at least since I've owned it. Around 900hours on the engine. I'll check logs for any work before I owned it.

How do you like the Kx-200? Was it a true slide-in replacement as advertised? I am thinking about ditching my KX 165.

I believe that both sides should align to the same position with respect to the stab. You may need the travel boards to check the alignment. Hard to eyeball.

Mine is 1783, so that would apply. The nuts are fixed into the plate, so they don't turn. That's how you keep them from turning. As for the sealant part, my understanding is that they seal the nutplates, then apply a sealant to the edges of the cover and it seals when tightened. Not 100% on it, but I'm getting ready to learn I suppose.

Looks like a through bolt. How many hours are on the engine? Any recent work on the cylinders?

A bit more context on the engine.

Thanks for checking

Sheared side of the bolt is cylinder 6 toward the propeller. The backed off side is in front of cylinder 5
