we has ours done. it was really expensive.

We just got a couple of Gibson cylinders in that the customer supplied for a bonanza, they painted all of the flanges, but they didn’t paint the barrels black, and they also painted the exhaust port. So by the time we stripped the paint under where all the base nuts go, and we stripped the paint off the exhaust flange that takes time to do. And then we had to put the cylinder on the second day to get the paint stripper time to work. The honing looks like it was done with a bottle brush by hand, and the scratches were 45 degrees at the bottom of the barrel and 30 or less at the top of the barrel. We didn’t even have time to check the choke and out of roundness and the bore diameter but I bet you that stuff wasn’t straight either. It looks like a bottle brush hone was used on the cylinder and then they painted it with a rattle can in nine minutes and sent it out. I wouldn’t put a Gibson cylinder on my Neighbors weedeater.

Call them, but on their Facebook page and via email they said they are FAA authorized to coat L C and F lifters. Byron, We have approval to do all of the Lycoming, Continental and Franklin lifter bodies. Sincerely, Chris Collum COO Airworx LLC. 251-809-2959

C models with the doghouse run hot on takeoff. They run hot in cruise too. You can re-jet the carb for more fuel flow or you can send your carb to msacarbs and they can open up the main jet.

We have a 2700 hour one here, it’s about 4 or 5 hours for a quart

I have a new electric 28v cowl flap motor that’s available.

There’s one for sale on eBay.

How is an autopilot installation a minor alteration?

The CGR does not have more functionality or is better than a Garmin 275. For one thing it’s not touchscreen, for two it has this knob you have to select between four pages to see everything. And three it doesn’t even display all of the primary information on the page, you have to look at page 2 to see amps or oil temperature or whatever it is that you selected there. EI said it couldn’t be done, but Garmin has it.

If you were gonna do that, you should just put a Bendix 1200 in the same hole and run that. But no STC is gonna specify some other manufacturers hardware.

Those Carling switches are fragile and they break, plus every one of those switches requires a circuit breaker, annd most airplanes that don’t have enough room for circuit breakers as it is.

We had two Bendix’s 1200 magneto‘s for years. With the electro air, when you switch off the Bendix, it slows down about 1 mph, and when you switch off the electroair, it slows down about 2 1/2 to 3 mph. That’s about the only change I can tell.

You can’t remove a roller lifter from a Lycoming without splitting the case.

It needs to be installed properly, I have an electro air on my plane and I have a BX 1200 magneto, but it’s very marginally better than the 1200 Bendix magneto. It does run warmer, it doesn’t start or any faster nor idle any better. I don’t really get the dual installation. It’s probably $9000 by the time it’s completely installed with all the labor, and then you have to have a separate battery pack, and I see the small benefit with one of these, but two of them there’s nothing additional. And you’re replacing a pretty robust and reliable, dual magneto for something that’s way more complex and although it doesn’t have any single failure points, like the Bendix dual magneto does, it can still leave you stranded a lot easier and probably more likely. I’m not sure how long that backup battery lasts, but when that goes dead, the engine stops running. I kinda like the idea of something that makes its own electricity.

They often don’t seat properly and then they use a lot of oil and they run hot. And then often times, by the time you get to 1500 hours or even 1000 hours, they polish iut smooth and start to use even more oil so I’m not so convinced they’re a good fit for Mooney especially. The ones selling chrome and nickel plating. Options are the ones who were taking cylinders worn out past standard boar and then re-roaming them or nickel, plating them back down to standard size. But that sounds like a solution looking for a problem. It may not be the solution you’re looking for.

DLC coating has come on all Lycoming engine lifters that they ship now, as far as I know

We sent the whole top end of our engine off to Ly-con to have it ported and Cryo treated and everything else they would offer for those, its probably 2kt. faster. 5-8hp perhaps. We did also have the Alodine cylinder heads with a black barrels, and we painted the black barrels ourselves of Cerakote.

I’ve had this happen to my legacy 750 a couple of times and if you pull both the com one and NAV one breaker and then reset them that will free that up. It will Reboot the unit. It’s not guaranteed to fix it, but mostly it takes care of it. But I’m with you, I would need a second NAV and com, and if you really want to cut cost just a second NAV, com is a luxury, but you need to have a second way to get out of the clouds if your navigator goes TU.

I have a ballast for one if you want to try it

But the prices have gone up 40% since pre-Covid so I’m not totally sold on this. I guess when the door seal gets to be $500 we can talk about it again. All of the price increases by the Hartzell family of companies (Arcline) was not related to supply and demand.

Stainless screws tend to gall and seize up in the nut plate and then break off and then you have one heck of a problem. We just started using more and more cad plates steel fasteners, which don’t do this nearly as often. Spinner screws in M20Js are another notable example.

Because I broke yours and I ate the cost of the 2 Rpm version before I figured out I bought the wrong one, and then I ate the cost of the other one. So I’m pretty well-versed.

There was a one Rpm version and a two Rpm version. And if you buy the 2 Rpm version, the cowl flap will blow open or closed because the air pressure drives the motor through the gear train. So get the right one.
