Pmaxwell Posted October 5, 2020 Report Posted October 5, 2020 We picked up the Mooney predator this weekend so we can make it fly again. Out of all of the restoration projects we’ve done this will probably be the most exciting Mooney we’ve worked on and I’m going to keep this thread updated with our progress as much as I can. With the help of some former and current Mooney employees who have worked on it we hope to have it flying soon with maybe a few updates along the way and hopefully those who have dreamed of fly it will get a chance. 18 Quote
PT20J Posted October 5, 2020 Report Posted October 5, 2020 Paul, Did they ever fix the aileron control problem? When Roger Hoh (contract flight test engineer specializing in handling qualities) flew it during development, he told me that at higher speeds the ailerons drifted up putting the push-pull tubes in compression and flexing them forward against the guide blocks causing a lot of friction. Roll forces were very high and the stick would stay wherever you put it. Apparently this was one of the reasons the Air Force passed on the design. Skip Quote
carusoam Posted October 5, 2020 Report Posted October 5, 2020 Waaaaaay Cooool Paul! The dream machine flys again! When that flys... Transition Training will be considered cool again! Where can I rent some Mooney time, will be answered with Go see Paul, and fly the Predator!(?) Was it the M20H, or T? (I can’t remember many of the proper details) perfect for everyone that has flown everything from A-V... H & T, I think both vied to be an AF trainer... must have been fun days in engineering in those times... Did I mention how cool that machine really is, and what it means to so many MSers..? Amazing... Today isn’t April first, is it..? Best regards, -a- 1 Quote
carusoam Posted October 5, 2020 Report Posted October 5, 2020 Some history, but not much... See who left a comment at the bottom of the article... Dr. Robert Achtel....

I’d have to watch Boots movie again, but I believe there’s a segment describing some sort of canopy that was hap hazardly bolted in place temporarily for the initial military visit to the factory. 1 Quote

Tom Bowen said they didn’t get the contract because the roll rate was not high enough and later they tested some other positions with the friese ailerons which allowed a 7 second roll rate but caused the airplane to be dangerous at slow speeds. The airplane was flown after Tom and some other employees put it back together. It was flown regularly by some of the Mooney employees. The configuration it is currently in would be too dangerous and it will be either converted back to the slower roll rate or maybe even a regular aileron and flap. We are still waiting on more data to make that determination. 4 1 Quote

Anyway it will be lovely to see it fly again. 1 Quote
Pmaxwell Posted January 29, 2021 Author Report Posted January 29, 2021 Engine is overhauled. Can’t wait to fire this thing up. 6 Quote
carusoam Posted January 29, 2021 Report Posted January 29, 2021 Proof that it is an aerobatic engine... Works equally well right side up... Paul how many HP do you expect to have in that fine machine? Best regards, -a- 1 Quote
Pmaxwell Posted January 29, 2021 Author Report Posted January 29, 2021 300hp at 2700rpm. We are looking at mag options now. 1 Quote
Greg Ellis Posted January 29, 2021 Report Posted January 29, 2021 You can tell that this engine was built by professional, knowledgeable, intelligent mechanics. How you ask.... By the calendars of scantily clad women on the walls. 2 3 Quote
201er Posted January 29, 2021 Report Posted January 29, 2021 Does it come with ejection seats or are you retrofitting them? Quote
Seth Posted January 30, 2021 Report Posted January 30, 2021 That’s so cool! Cant wait to see how it compares to the Missile in speed and climb as it’s also 300 HP on the mid mody. However I’m sure it’s heavier with different construction to be stronger. But not a four seater and not sure about fuel tanks. Likely 64 like the J. -Seth Quote
Pmaxwell Posted January 30, 2021 Author Report Posted January 30, 2021 72 gallon tanks. It was a k model wing bolted where the short body mooneys were attached. It has a Porsche tail cone and a mustang tail. 3 Quote
Schllc Posted January 30, 2021 Report Posted January 30, 2021 Sounds and looks like it’s a frankinmooney. ive see the photos, and caught snippets of its story, was it a haphazard attempt to compete for a military contract or was this a earnest r&d result? what’s its story? Quote
201Steve Posted January 30, 2021 Report Posted January 30, 2021 That’s my wing! So close to greatness! I’ll never wash that wing again. Lol 1 3 Quote
KSMooniac Posted August 31, 2021 Report Posted August 31, 2021 I was there in July and it seemed to have stalled for the time being. The shop is beyond full with paying work and customers anxious to get in and out... I waited many months for an opening! A good business will take care of customers first... Maybe we'll see it at OSH next year? Sent from my LM-V405 using Tapatalk 3 Quote

Surely it can’t have ejection seats, they are BIG and HEAVY, we had to put a stand under the tail of an OV1 Mohawk if we pulled a seat, and a seat required a crane, had to weigh at least 150 lbs, maybe more.

All ailerons do, or all airplanes that I have flown do. I’ve adjusted ailerons so that in flight they were level with the wing and not up. all it did was increase control forces. I assume they may have been at airspeeds that we should never see Edited January 28, 2022 by A64Pilot Quote
jghyde Posted May 1, 2023 Report Posted May 1, 2023 I had the opportunity to ride along and fly the Mooney M20T Predator over the weekend at the Mooney Caravan Texas Formation clinic. Here's the report. 3 Quote
