I appreciate Mark's rant on screws. Very true and applies across many industries

[@SmittySmithsonite]

YES - as an auto mechanic, I agree 200%! One of my biggest pet peeves was the reuse of totaled fasteners. You can waste the entire billable job time on ONE stupid fastener! 😵

[@chevyon37s]

No joke. Especially since they’re repeat customers and the damn thing gets inspected annually, it benefits the techs to replace those screws for the next time they work on it.

[@chauvinemmons]

Many fasteners only used once on removal must be replaced. I'm not totally on board with that but at least every other time.

[@SmittySmithsonite]

@@chauvinemmons On modern automotive engines, most of the time the cylinder head bolts are TTY (Torque To Yield), and can only be used ONCE. When you torque them to spec, they stretch to just a hair below their breaking point. Reusing them is a great way to ruin your week, lol.

[@travisjohnson8210]

Screws are cheap! Reputation is not. Replace the screws as a pro style service.

[@Asta-wl8jz]

Your parents must be so proud to have raised 2 wonderful men. Y'all are amazing.

[@DanielSMatthews]

My wife gave me two sets of twins, I hope they are as successful as these guys. There does seem to be something to working in a team where you are that closely in sync with the other person.

[@TNels]

I believe they have 6 bothers/sisters

[@dabneyoffermein595]

@@TNels i believe that to be true

[@DaveHines1]

My twins learned to cooperate before they could talk , unfortunately it was one distracted me while the other took my wallet out of my back pocket 😃🤣 true story !

[@rfinsl]

love the camera person who's spinning in the chair in thr background!!! love it!

[@charlieguenther5490]

Thankyou Mike. You sent my brother some Scrappy parts last year (you didnt even charge him). He passed away a few months ago. He talked about you all the time. Our passion was aircraft and we worked together. Its nice to see you and your brother working with each other. You flew over our house one day in Turbulence and it blew our minds (it is ridiculously fast)! I hope to see it fly again some day. Be well and enjoy pursuing your dreams.

[@Russellsperry]

I would love to see Mark do more airplane building videos. I understand he’s busy with the business, but damn! 😅

[@danmcburney3247]

👍👍

[@FlyingHutch419]

I always thought Mark was the serious one. I was cracking up!

[@GeoffInfield]

Yeah he really relaxed into it quickly, very cool.

[@arturoeugster7228]

Watch the problem of the stall, The stick pusher, landing on a soft field, performing a full stall landing, will push the nose into the ground , if disconnected, the left wing will drop first, sharply. Test this at altitude. Be sure you have control of the stall process! 🔥 The stall problem is reduced when olny part flaps are set, remember full flaps is the critical configuration Watch blancolirio Mesquite incident ! [ Swiss aerodynamicist here, familiar with the STC process]

[@portnuefflyer]

I'll never forget when I dropped in at the late Joe Clarks "strip" (think airport, that big), and he said on the radio to go ahead and land he was just wrapping up his routine in his PC-12. For the next several minutes I got treated to a great aerobatic show. It's a crying shame you guys never met, he was a a 12 and a 6, loved the brand.

[@jasonpressler7111]

the easiest way to tell Mike and Mark apart is by their demeanor and volume.

[@WestCoastWheelman]

These are 2 twins I've never had a problem telling apart! It's the voice. Close your eyes and you'll still know who's talking.

[@billhart9832]

The Patey twins share much but their skill sets are both complementary and overlapping. Literally a pair to beat a Full House!

[@SmittySmithsonite]

2 of my best friends from the old neighborhood are twins. I learned really young to notice the subtle differences, so now that I'm much older, I can ALMOST always tell twins apart from each other. My biggest issue is remembering names. I know Mike and Mark from the years seeing them on KZbin, but for people I just meet, I'm TERRIBLE with names, twins or not. It's embarrassing! Same with names of streets, newer cars, newer parts, etc.. Must've been the part of the brain affected by too much fun in the 80's, lol. 😁

[@Jbryant93]

This channel is so underrated! Love the Patey bros!

[@brianwaldo2642]

Well Mark, I definitely think you are the comic relief between you two. This is shaping up to be a brilliant conversion and retrofit.

[@Turbulence210]

Mike and Mark Patey are awesome, keep up the good work! hope to see Draco-X soon! and congrats on 300k subscribers!

[@Trophyman]

Im wondering if thats where the old pilatus engine is going

[@airhammer6203]

@@Trophyman does it have more power? I'm pretty sure, in a previous video, he had Draco's engine rebuilt.

[@SgtErvom]

I am so happy to see the other brother involved. You can finally see where Mark steps in and is just an amazing support system and awesome banter between these two. Thank you both for sharing and I can’t wait to see more.

[@ryanmcelroy5512]

When I had my 1999 Station air T206H I got the garmin auto pilot G500, and loved it. Hope to have another soon

[@benjamin.DWG1]

The pc12 is my favorite plane, I’m so excited for this build

[@mfcarver0130]

I love how the PC-12 looks like it has a giant smile when the cowling is off.

[@davidr8264]

I think Mike should do a top 10 reasons why he prefers Garmin over other companies. I'm curious to know why he likes them so so much compared to other options.

[@mattym8]

They’re very good.

[@Airplanefish]

What other options? Not many for certified. It's a Garmin world out there

[@UTarcher72]

Sponsorship is why.

[@SoloRenegade]

they sponsor him...

[@jpmeyer4159]

Way fewer steps with the gamin touch than with the Apex. Garmin is much more intuitive.

[@matswallsten1628]

Such an inspiration to follow you guys. Nothing seems impossible to you, having your business, building crazy houses and airplanes and mostly being good people ❤️ Looking forward to follow this project as well. Thank you for taking us on this ride with you. My favourite channel on KZbin

[@dylanjamesweggz3573]

Mark couldn't be more right and fair regarding the screws. He certainly mentioned it in a far nicer manner than I would have.

[@danielhawley6817]

What a clean and neat interior with a few stripped screws in the floor...I used to be an aircraft mechanic in the 1970's, working on interior mx and cargo conversions on DC-8's and genl mx on C-130's. One of the most pleasant jobs ever is pulling literally thousands of crews up from the floor panels of a C-130 so they could all be pulled up for cleaning and inspection. The aircraft has been hauling every type of cargo from oil drilling equip to fresh fish, many of whom have fallen out of the bins and now reside rotting in the sidewall of the wall panels. Many of the screws are stripped and or filled with gunk so that they won't come out easily. Also the foreman insists (so that no more screw heads are stripped) that no pneumatic screw guns be used, (we didn't have electrics then) only hand held screwdrivers and an old fashion crank driver which gives you a little faster extraction. Oh, and it's very hot and the removal of the sidewalls and the resulting fiberglass dust has your skin on fire...and you just knelt down and your knee kit a countersunk scree head. A great motivator to find a more professional line of work!

[@avflyguy]

Another worthwhile face lift and a new heart for the beast. Gotta Love it! Feed us more, more often!!

[@jefffrank48]

Mark/Mike, I can really appreciate your comments regarding the stripped screws on your $35K+ annual. Overall, the problem of common sense not applying to annuals is endemic in the aircraft maintenance industry. I often find and am puzzled by not replacing screws, wires, connectors, etc that have minimal cost because "it still works" mentality. You should see the 40 year old wires and connectors I just discovered in one of my airplanes back from annual on landing gear microswitches.....

[@swampydouglasobannon8804]

Good to see more of Mark love to watch you guys work on airplanes At 66 and disabled this is Something i can't do except through watching you guys it's so much better than a good book that you can't lay down 😁👍🍀

Good to see Mark in a video again

[@BurtGummer357]

Mark and Mike, what a great job from both of you Mark you did such a wonderful job on the video keep it up. I really love all of the A&P references I used to be an A&P mechanic for my dad‘s charter service on one old 1955 Aero Commander so it really hit home. I have followed both of your videos for a long time. Mike does a fabulous job but I’m glad to see that you’re on board and I followed you as well. I think your new “saying” should be…Mark’s going back to work??? I know Mike’s building a house that takes his time, but both of you guys do such a fabulous job for General aviation. It has renewed my interest, faith and belief in what can be done. I love the N number on the Pilatus, but I have to agree let’s party is the way to go, my dad‘s old plane was 00B miss it a lot but happy to live through you two brothers! Had the good fortune of meeting Mike and the Flying Cowboys in Reno the day before Draco’s mishap…look forward too what you and Mike have coming in the future great job to the both of you!!! Congrats and let’s Party Patey brothers!

[@heathwellsNZ]

Wow - I am very much looking forward to future videos on this project!

[@billhart9832]

As always immensely informative and entertaining. Slipping in some constructive criticism for service providers, demonstrating best practices for weight management, and making a great promo for Best Tugs in action with Mark's casual but completely confident backwards stroll w/ his freshly mod'ed "Pilatypus" following like a well trained puppy. Cliffhanger ending to keep us waiting for the next episode. Same Pilaty-time same Patey-Channel (or possibly @801pilot!) Well done. Oh, and Lima Papa... Limitless Potential!

[@WisdomFromAshes]

I'm so excited for you both! I'm here living vicariously and enjoying every minute of it. Thanks for sharing. We will watch closely with great interest and excitement.

[@jamessimpsoniii2029]

As a new to aircraft as in I've got ground my first ground school class scheduled a week away and a neighbor with A&P training going to look at what I'm hoping to be the same type of not same plane that enthralled me at age 6 a Cessna 195 with 69SMOH and the sexiness of a 32 highboy within my budget so Im hopefully passing up on a 172 and tail dragging the the ground and putting a dream on tap all 34 years later. Love you guys with Drago and Scrappy and Rebuild rescue as they made my side hustle of repairing cars over the last 3 years pay for my lessons and hopefully a beautiful 195.

[@garycoloradosprings3947]

Fantastic video. I really enjoyed the several comedic clips, great stuff. Awesome to see your tug in action, what a creation!

[@michaelmcdonald6727]

Hey Patey’s, I worked a Depot at Hill AFB just north of you guys. I worked F-4’s and F-16’s on the production line. We always replaced the screws and bolts we took out with new. The locking nuts and nut plates were hard on threads and you don’t want a fastener coming out of a jet on a mission! Thanks much for sharing your video.

[@gregoryschmitz2131]

Another good laugh. When I was working (Air Freight Op) the wires never got pulled out of the ceiling. Huge bundles of abandoned wires as tech advanced and left in place. I had an office that had a huge pile of Conrtoler com wires, from Coax to the latest blue hose. When I got done (carefully!) huge feet came out and it was just a small bundle (and management would not even let me pull the Coax out of the runs to the main brains to make room in the conduit for future runs. So much falls to management stupidity.

[@gcrauwels941]

Enjoyed this. Can't wait to see the numbers.

[@SilentCream]

All but one of the 12's I maintain has the Finnoff -P model and I love it! One huge recommendation is replacement of the older style wing fuel sumps with the newer style ones!

[@bendo7418]

100% agree on the issue putting new screws in once the originals are worn😬 thats the reason i like to check my plane before panels get back closed… too many shops want to skip the little extra time but fail to understand that it makes all the difference.🤷🏼‍♂️

[@dufus7396]

All those considerations , recording performance,and experience..for an optimum improvement. I was impressed about pilot workload the most..plus less flight time ,and greater power saftey margins. Ive always gone with the idea of bigger means easier workload for engine also

[@forceablepizza764]

lol, that yellow stuff is yellow 3M. its great stuff. you use that to put something together that you never want to come back apart. I use it to glue random parts to my engines. its a pain to clean up if you ever do need to take it apart again, but good stuff.

[@chrispy104k]

Love the attention to detail and yes, if the screw is not in good order throw it out and replace it. One of the tools that ruin screws is electric screwdrivers used inappropriately or not mated fully to the screw. Anyone using a rattle gun to tighten up wheel nuts (lug nuts if you prefer) on my car will get a thick ear. Hand tighten and then use a torque wrench with the appropriate setting.

[@tomcoryell]

I just run them up to where they are not yet tight with the impact wrench and then grab the torque wrench.

[@drethanplasticsurgery]

I really like the pace of the PC-12 engine swap. I was pleasantly surprised how much faster you showed the conversion
