If I baloon a bit, I just hold what I have and as the airplane settles, add back pressure and increase angle of attack to slow the sink. If the sink then overpowers the increasing AoA a tiny bit of throttle smoothes things out 201 turbo's method learned from the old fart is also a great way to 3-point a taildragger, which is what I learned in. I haven't played with the less flaps in windy conditions bit, thinking that doing the same thing each time reduces a variable. However I wonder if Hector doesn't have a good idea. It's always a little gusty and the air roils due to hills at my home airport, maybe my "same every time" amount of flaps should be less than Full. Opinions? Gary

Jetdriven: Sometimes, nothing… Flying slower with no fuel stop is always faster I've played that game. Even a fast fuel stop Ads 45 minutes to an hour

chrisk: Pleased to meet you, we'll have to get together and compare notes sometime, Rbridges Thank you very kindly, I got a Cover from Rainman and had an enjoyable flight to Boerne

The thread on my cover had had it. It is a Bruce, several years old, I am not the original purchaser, but Bruce will re sew it for me on warranty. Which I think is mighty fine treatment. Anyway I have to ship it to CA, and I expect it'll take a couple weeks. All fine and good, but here under the X in Texas it has been so hot that my JPI wont work if I leave the plane uncovered in the sun. No hangars are available. So if you have a spare cover that you aren't going to use for a while, I would greatly appreciate a loan, and we will figure out some nice way for me to say thank you. Gary 512-923-1904

Take air is right. It attaches flow to the tail

Orion That makes perfect sense to me Skypylot Thanks that's exactly what I was looking for, thanks to all and specially to you for responding Gary

Nice paint Yvegs. I see what you mean. The uncovered part is not not huge, but it goes against what I think I know about aerodynamics. (And folks, me included, are always allergic to something that refutes what they think they KNOW). I imagine air buffeting in and out of the hole, generating more turbulent flow downstream of the hole, and air being accelerated, drug along by rather than merely pushed aside by a covered hole. I think that I want to accelerate the airplane, not the air. In AR-15 rifles there is a hole in the barrel to bleed gas into a little tube that cycles the action. With a borescope you can actually see erosion of barrel material downstream of the hole in a pattern that suggests turbulent flow. Although I am suprised that the benifit is apparently so little, thats still a relatively cheap 3 mph, and I am also surprised that it is not a more widespread mod. Gary

I called them today, they said show up in October.

Thanks for all the Information guys. Openskyflier: the calipers are already rotated I believe. To all; I'm astounded that covering that really pretty giant hole In the bottom of the wing better is only good for a little more speed than one or two mph. Does that seem weird to anybody else? There must not be much going on In that area under the wing aerodynamically speaking. Gary

Once again my mind wanders to the ignored elephant in the room, that giant hole in the bottom of the wing. I have a SWTA modded F that runs pretty nice, and wonder about putting inner gear doors from a J on the gear. It seems like such a no-brainer, but I never hear any gossip about it, and wonder if there isn't some fatal flaw with that bright idea. Anybody tried this, how complex was the change? I have heard from DaV8or that he has heard the gear gets hard to swing and from Jetdriven that they are good for 3 Kts. Whats the skinney, guys? I would appreciate hearing from anybody who has already invented that particular wheel (well cover). Thanks, Gary

I don't know how germane this is to our engines but marvel mystery oil got it's big push into the aviation world when the airlines started running it in their DC 3 motors to alleviate valve sticking

I have seen the boot that the guy that Jetdriven referred to makes. It's a better boot. And In this installation because the boot is under a constant misalignment strain and then also receives some intermittent additional stretching when the engine shuts down, better really is better. I have the original style boot, paid a ridiculous amount of money for it, and view it as one of the only Under engineered parts in my entire plane.

The transducer was fire sleeved, the wires coming out were not. I subsequently wrapped the connector (after the second time it got oil in it and began to fluctuate) with some heat melding Scotch brand electrical wrap. It doesn't take much oil, my transducer is located under the left side cylinders near the bases which must be an oily place. I get a very small amount of oil out of the pushrod tube seals, and thats probably where the oil comes from and then gets blown down by the cooling air.

Turns out the fix was cleaning the oil out of the 2 pin connecter at the end of a little short pigtail that comes off the transducer. There wasn't much oil in the plug, but evidently enough to allow some shorting, or possibly some insulating of the connection.

Good stuff and interesting reading, thanks to all who have taken the time to share their experience. Gary

All the above is good advise. If you are going to Cam Guard or MMO it, consider putting the cyl just before TDC and pulling the top plug and filing the cyl. with the juice. Put the plug back in and GENTLY pull the prop to TDC. This will force concentrated magic juice into the ring area. It seems to work better. Back in the day, Eastern's SOP for the ( I believe it was) 1820s in all their DC3s was to run MMO. They thought it helped sticking valves. And they did fly around the block at least a time or two. Good Luck Gary

The benefit I see for climbing LOP is controlling CHTs on hot days. It really works, and still get 500 fpm at 120 mph indicated at light weights.

Oooo Cool

Our Mooneys have lots of power compared to some of the groundpigs I have flown in the past, and you may very well have been able to wish her off 3/4ths of the way down the runway, and stager over surrounding terrain. However, the day you are just a little too heavy, there isn't quite enough runway left to stop, and the trees at the end of the runway look just a tiny bit taller than you can climb, generates that 'I have been irreparably stupid and am about to pay a price that I do not want to pay' feeling that reinforces the correctness of your no-go decision. This is a lesson that can be learned either cheaply, or with lots of anguish. High altitude airports minimize the apparent danger the and multiply the chances of getting caught. You did the right thing, and those other guys may be experienced enough to get away with over gross operations, or they might just like flying enough to die for it. We aren't teenagers anymore, and take a long time to heal. And it smooth "taint fair" to leave our survivors in the lurch due to a moment of impatience. Gary

The fuel savings can be more than a gallon , I usually see more than that, but the real benefit is keeping CHTs low. I climb LOP in TX in the summer, as ROP overtemps the cyls. when OAT is 100df or better on the dirt, and I,e seen 80df at 7000 feet. Works like a charm, about 130 indicated and 500 fpm in the low 9 gph range. Warmest (#3) will stay below 380df. It doesn't work so well when I am heavy, but solo works like a champ.

Testwest, where are you in our hour of need? Gary

I concur with n74795 that it is a harmonic or sympathetic vibration possibly in the control pushrods.

I'll sometimes climb at 9.3 gph, 25" MP, 2600 rpm which is 69%, 130mph, 500 fpm 370df CHT. 8.7 GPH yields cooler CHTs. Both are kind of easygoing cruse climbs.

I'm looking for 8.5 to 8.7 GPH, and smooth engine operation. Typically winds up 30-50 df LOP, 165 to 175 mph true from 5000 to 10,000 ft. fastest at 6-8000ft on a cool day. This is in a SWTA modded F fairly light.
