Why would you? The plane climbs a lot better with the gear up, and the gear doors are pretty easy to overspeed. What happens in a partial power loss scenario? Are you comfortable with that risk? Sent from my Pixel 3a using Tapatalk

Adding to this... You WANT fresh air to be leaking into the cabin, unless you've somehow got a pressurized Mooney. Need air to breath. Any unpressurized aircraft is going to see intermittent exhaust ingress on the ground depending on wind angle. If air can get on for you to breath, exhaust can be blown in by the wind. The important thing is that you get no ingress in flight, any phase, and that when on the ground you can clear the ingress by turning into the wind. Sent from my Pixel 3a using Tapatalk

In the event of power failure after takeoff, do you want best range or minimum sink? While the airspeed for minimum-sink is not published anywhere I can find it, my own experimenting tells me that 85 mph is probably close to being the correct number, especially with flaps extended. Flaps and gear up at 105, sink rate is ~800 fpm (over 1200 in a 30-degree turn). At 80 mph with approach/takeoff flaps, I see way less, more like 400 ft/min. Sent from my Pixel 3a using Tapatalk

My equipment list says Mallory SC628P Safe Flight 164R For gear alarm and stall horn respectively. Had to replace my gear alarm a while back. The current version of that part number is smaller and has a plastic housing compared to the original, but it's still in production.

Hanging a weight from the engine mount

Put mechanic's creeper under the tail? -
Cut the thumbstick off a PlayStation or Xbox controller and glue it on top?

Density altitude performance with a 1964 M20E
ShuRugal replied to Pilot boy's topic in Vintage Mooneys (pre-J models)
I don't have any Mooney-specific documentation, but I have seen a lot of information about mountain flying which states that when conducting high density altitude takeoffs, you should lean to peak RPM during run-up and use that setting for takeoff. I'm sure someone more qualified than me will either back that up, or explain why it is wrong and what the correct action is. -
Electric gear issue 1965 M20E
ShuRugal replied to Luxuryairtravel's topic in Vintage Mooneys (pre-J models)
Sounds like a faulty switch or a cracked wire somewhere on the retract side of the circuit. That said, you're a braver person than me. I wouldn't have left the pattern if the gear were being stubborn about retracting. -

About 90 minutes. Dude's built like a toothpick. No idea what his hydration state was before the flight, but he wasn't showing any visible signs.

Sunday was neither of those things here. Day started at 80F.

Well, I took a friend up for a flight Sunday, and it nearly resulted in calling out EMS. Hot day, and by the time we got back into the pattern, he was experiencing hydration-related muscle cramps. Got some water in him and sat him down in the shade, and he was fine in a couple minutes, but it sure was a wakeup call. Failure of planning on my part - I should have remembered to bring water along (I keep a fridge in the hangar stocked with it for exactly this reason...) I have just added a box of single-serve packages of powdered Pedialyte to my flight kit for mitigation of this problem in the future.

New seat embroidery suggestions
ShuRugal replied to Dbrown's topic in Vintage Mooneys (pre-J models)
I had a T-shirt embroidery company do me up a set of polos using that logo/registration arrangement in the colors the registration is painted on my plane (gold trimmed with maroon). I think the company was Queensboro? Something like that. I bet they'd do a set of patches of asked. -

Have you considered getting someone to do an embroidered patch that you can sew on? -
Inside the cockpit, at the corner of the firewall and nose wheel well. Colossal pain the ass.

Landing gear breaker tripping
ShuRugal replied to mikebroady's topic in Vintage Mooneys (pre-J models)
Get your mechanic to give it a thorough checking. Low voltage alarm followed by a popped breaker indicates something is binding and overloading the gear motor. I don't know what your alternator/generator is rated at, but for the gear motor to drag your system voltage down far enough to get an alarm, it's drawing a few hundred watts. Mooney landing gear is very simple and designed to be operated by hand - there is no way that much demand should ever be placed in the motor. Good idea about the limit switches. If one is slightly out of place, that might result in an intermittent overrun condition? Either way, you need someone with experience working on Mooney landing gear to put hands on it before you do permanent damage to the motor/drive. -
1/3 the handle travel to get from 2700 to 2300 is about right for me. When I want to do super slow cruise at 1900 RPM, that takes 2/3 to 3/4 of the travel.

Flap Retract on Takeoff
ShuRugal replied to moontownMooney's topic in Vintage Mooneys (pre-J models)
You will climb faster with the retracted than extended. The gear adds a lot of drag when extended. Drag means more power required for the same speed. Power is required to climb. If you are using power to shove the wheels through the air, that power isn't being used to climb. I typically notice an increase of ~200 fpm at Vx when I suck up the gear. In the event of an engine failure 1 minute into climb out, that 200 feet could be the difference between life and death. If you are operating from short field with obstacles, Vx retracted will get you a steeper climb than Vx extended. Even if you have an engine failure at the exact moment you retract the gear on takeoff... So what? It takes two seconds to extend them again. If you don't have that two seconds, the plane became property of your insurance underwriter the moment the prop stopped. A belly landing is perfectly survivable. Landing on the departure threshold with your gear out might not be, if there's less than 500' between the threshold and the trees. -
Flap Retract on Takeoff
ShuRugal replied to moontownMooney's topic in Vintage Mooneys (pre-J models)
My IA has me unlock them and put the bar in the middle of the travel, then moves them himself to check for anything binding at each wheel. Then concludes with one slow as I can move it retract, and one equally see extension. -
Flap Retract on Takeoff
ShuRugal replied to moontownMooney's topic in Vintage Mooneys (pre-J models)
Always fun to introduce a seasoned GA pilot to a Mooney. "You put your gear up too... Oh, they're back out again? And there they go away again. Right, I get the picture." -
Above the sheet metal, there's another frame member identical to the one you can see in the picture. Top of the bolt is on top of that tube. Tightening the bitch is a two man job - one inside to hold a wrench on it, one outside to turn it.

Flap Retract on Takeoff
ShuRugal replied to moontownMooney's topic in Vintage Mooneys (pre-J models)
My butt must be extra sensitive. I don't notice any loss of lift, but I do feel the pitch try to change. I can usually control it with extra yoke pressure so that my passenger doesn't notice, though. -
Flap Retract on Takeoff
ShuRugal replied to moontownMooney's topic in Vintage Mooneys (pre-J models)
If there's no obstacle to worry about, I retract at the top of white arc. If there is an obstacle, or if there are no good landing spots dead ahead, I climb with takeoff flaps at 100 MIAS to pattern altitude, then retract them and accelerate further.
