MAD PROPS - MT Constant Speed Propeller Upgrade

[@Stringman1950]

As good as all your stuff is, Trent, you’ve got the best “intro” music track/vid feed going. Always energizes me. Pleasure to keep up with you. Cheers.

[@richardsalmon8256]

It's really good cinematography. I've shown non-AV friends his videos and they always seem captivated because of the intro. Awesome work Trent!

[@theguy8555]

thats interesting, the only thing I'd change about his vids is the music. I often wish with so many tastes in viewer music, creators would upload music-less vids alongside the standard vid. I'd much prefer watching with my own playlist not clashing with the creator chosen music.

[@Stringman1950]

I kind of go back and forth. But his intro pops ... music is personal. Cheers.

[@uliman100]

I work for MT Propeller and great to hear that you are happy with your new propeller... Greetings from Germany

So nice of you to give MT.... Props

You have the best intro’s on KZbin another awesome video Trent !!!

[@JonasMarcinko]

Props on the new prop!

[@danielvanheerden9935]

Hi Trent I am a 66 year old man in South Africa. i Own a Savannah stol aircraft and only started to fly 3 years ago and enjoy it flying it. I really enjoy your u tube videos and find them educational. Thanks. Daniel

[@DCGULL01]

Wow- super happy with the outcome. Was concerned about the added 20 Lbs. on the nose, the smaller overall blade length, AND the interaction with all of the data being interpreted correctly. Faultless computer decisions, tons of power in all ranges, attitudes and altitudes, no noted heaviness or loss of 'tossability' caused by nose heaviness, simple to use (no pilot overload) and no new bad behaviors. A total win in the super lightweight Kitfox. The Freedom Fox is a completely new machine- really crazy impressive. I genuinely like how easy it is to have and use and well-- No crazy training and planning to manage the process. Sweet. Very cool rig and so far away from the start of 2018, right? Carbon Cub, Highlander, Maule and now Kitfox at the top of the heap of STOL aircraft. (Draco excluded as a M. Patey 'One Off'). What an awesome trip, Trent- thanks for taking all of us along. Legit question: Is there a Kitfox version with a larger empannage? One you could swap in from an older or newer design? That would keep it pure Kitfox and increase rudder authority at super low speeds? It would be nice to have the added control while the wing is still flying...

[@YardLimit]

Great video. I like the way you go through the process of analyzing the new prop and corresponding airspeeds.

[@tyronneshoelaces8843]

Excellent! Good info. Hey how is our boy Nick?

Let me just say I am glad you are a youtuber. Always enjoy watching your videos. And you plane is as beautiful as ever! Happy to see you making change of props. Seems like a good gain for your style of flying.

[@nonormies2837]

Don’t meant to gush but Trent your an actual inspiration to revisit my aviation past and take steps to begin my pilots training. Your skill in production is mind blowing. Been a fan of GA for over a decade but you really know what to showcase for enthusiasts.

[@jcnme2020]

Congratulations Brother on All your hard work and your Buddies too ! Enjoy & Fly Safe.

Doooooood those performance numbers with the new prop are IMPRESSIVE! :D Love it so much!

[@MyHealthByDesign]

Trent, great to see the upgrades are all working out well for the Freedom Fox! And, thank you for your videos. You are partly responsible for me getting back into flying (after a 20 year break in training). I've got my PPL check ride on 5/23. Then I'll seriously be looking for a plane to build. Wish the Kitfox wasn't a year+ wait for a kit (thanks!).

[@thinkcivil1627]

I enjoy your videos. I had been on several float plane fly in trips in Northern Canada before, but that felt like a commercial airline flight compared to my first backcountry flight in Alaska. The pilot landed on a gravel beach, within a river on one side and a stream on the other. I thought there was no way we could land there, let alone take off from that short of "runway". It was like being on a roller-coaster. He dropped us off and took off with room to spare. But, I had my doubts about the return trip; with the extra weight of the 2 of us and our gear. I was blown away by how fast he got us in the air and how steep he climbed to get up and out of the valley. The fishing was excellent, but the highlight of the trip was the bush flight.

[@ralphmcnair2486]

What engine are you running behind that prop?

[@thinkcivil1627]

@@ralphmcnair2486 Hi Ralph, I think you are asking the wrong person the question. I simply was relating a story about my first experience with a bush pilot.

I have been away from flying since around 1990. I am pretty impressed at how far the Kitfox planes have come! Great video, makes me wish social security paid better I would love to have one!

[@chrisfowler6278]

As always Trent, great video. I love the build/development videos that you have been doing over the last year or so. They really make a hard surface instrument pilot want to get into backcountry stuff! Between your channel and Mikes (excited about the scrappy build!), you guys definitely keep aviation adventures alive and well!

[@nealhamil9817]

You have no idea how many people are asking this question!!!! We've talked before and I appreciate the responses! She has really evolved.....in really great ways!

[@mylesvrooman3709]

Trent - Love your vids ! Just a note to let you and your viewers know, that starting tomorrow (5-2-19) on or about 2:00 PM, at Atlantic Aviation in Reno, EAA's "Tin Goose" the Ford Tri-Motor, will be on station and giving rides to interested passengers for three days. Less that $100.00 for a great experience in aviation history. Cheers - Myles

Great Video, thanks. I am going to fly in June the Bristell RG with 915 and Hoffmann constant speed Propeller, no EMU for monitoring the Prop. So still working with the Blue handle. Looking so forward to fly that Aircraft.

[@harrisonjuhasz4045]

Beautiful aircraft! Has the pleasure of sitting in one at Aero Friedrichshafen this year, lovely machine. Very jealous you'll be flying one 😂

Constant speed should actually give you better mileage in cruise, like being able to shift into a higher gear in a car.

Oh.... I didnt even notice it.. mucho hours here

[@lvsqcsl]

What? NO INTRO? I was starting to have withdrawals.....Glad to see you back! That new prop has to be smooth; I can't see any of the aircraft waving at me. Sweet! There is NOTHING I like seeing more than you at the controls of that aircraft, Trent. Man and machine are definitely one! Now, get that seat pan upgraded and don't flip the plane over; could damage that new prop! You and Tucker Gott are tied for first place as my heroes. I might have to give him the nod because I fly a paramotor, but, who knows; you might see me flying a Kitfox someday! Cheers!

[@maxbootstrap7397]

Is that an MTV-34 propeller? You prefer 3-blade to get more clearance between ground and prop? When you remove all that junk from the back seat, will the CG be forward of the safe limit? Will it nose over? :-o Hope not!

[@danaskubic2145]

Great to see you again Trent. Awesome video as usual and an awesome prop. Thanks for sharing your check out ride. Looks like your getting great performance. I!d love to be your wingman.

[@KruddyKamiKaze]

Good to see you back in the air!

[@markthibault8579]

Thanks for sharing the performance data in terms of speed and fuel burn. Looks like that 915is is a versatile engine for STOL, especially with that prop. I'd like to see one mounted to a Zenith CH-750 STOL / Cruzer to see how it behaves in that platform.

[@iguanaamphibioustruck7352]

I got a ride in a p-51 (daughter birthday present) Brent Conner with Erickson. Turning 2600 rpm, 4 bladed controllable prop. Cruise at 350 mph, 30 gpm, @ 425 mph still 2600 rpm 50 gpm. Me, I am a private pilot with A&P but never worked at it. Expensive hobby. My point, you are duplicating the system in the p-51,,,,WoW!. Now you need a liquid cooled engine that will last 5000 hours without overhaul. Iguana

Awesome setup for sure. Getting close to the X-Cub performance and 20% of the cost!

It would be interesting to modify the H stab to an inverted airfoil, such as in the Zenair 701's and tip fence like the Porter to improve the efficiency of the smaller stab surface area.

[@heydonray]

Curious: Is your stab/elevator gap sealed? If not, have you considered it? Thanks for all of your hard work and informative vids!

[@turbolx5oh]

Sounds like it adding several MPH to your stall speed. Since that is one of the most important aspects of flying a plane like yours, I gotta ask, was it worth it given the added weight as far forward as it can be on an already heavy (compared to your old one) engine install?

[@portnuefflyer]

He's going in the wrong direction for a so called STOL aircraft, adding weight and complexity, you nailed it.

[@portnuefflyer]

I was at 13,500 K the other day, burning 4 GPH, and indicating 81 MPH. No turbo or constant speed prop, Just a Zipper BigBore'd 912S and a Luga 79" prop. Simple and light works every time. Down to 72 indicated, I was burning 2.5 GPH, still at 13K+ This low fuel flow of course gives vastly increased range. Climb rate was still 350 FPM at that altitude.

[@portnuefflyer]

Forgot to mention, Rans S-7S

[@jamesretired5979]

[@SuperAero]

@@terrya6806 Maybe two to get him some altitude followed by two to get him some airspeed?

[@Captndarty]

Hey Trent, I know this is an older video but I’ve got a question when you were running this prop. I have a 915 with the Airmaster constant speed prop. I can run full manifold pressure at climb RPM of 5500. How does the computer with MT know when to pitch to prop after the five minute max power limitation? Or do you have to pull the power back? If so, it would seem you would effectively be climbing at a lower manifold pressure than the Airmaster? Just trying to compare of the performance differences to see which one is better.

[@TurboMathieu]

Hi Trent, cool prop. I had a few questions: where did you buy the freedom fox, and how much did you pay for it? I’ve been looking for one online, but I could only find sports one(tricycle gear) or kit to build(on the Kitfox site). Thanks for your help

[@TgardnerH]

Do you have VGs on the underside of your horizontal stabilizer? If not, you might be able to delay the tail-plane stall with them, so the limiting factor is your wing's AOA. (I say underside of the stabilizer because that's the "top" or low-pressure side of that airfoil)

[@jamesburleson1916]

VGs might not be very effective with the lack of airfoil on that elevator. I think they work better on the wing type than the board type.

[@TgardnerH]

@@jamesburleson1916 That would make sense, though I wonder if "a little bit better" might be enough improvement for this application.

[@harrisonaero]

Do you have VGs on the bottom of your tail Trent? If not I'll send you a set if you'll install them to get your elevator effectiveness up a bit and your stall speed lower.

[@portnuefflyer]

Nice to offer Joa! Yeah, if he doesn't, he for sure should have, especially with all that extra weight added on the nose. They will make the elevator more effective near the stall. None of these recent mods have helped his landing speed, just increased his approach speed and added weight.

[@UltraLigero1]

Hi Trent, Could you please state if you had any special discount for the Prop", or not. Just to understand and to clarify. There are so many great products out there, especially when supplied for a 'great deal'. You know what I'm saying... I am a follower, and am very impressed ...generally. What's your view on Elevator gap sealing? I'm considering it as its always tricky getting that last bit of flare on the old Mk 2 at least. Look forward to your next Vid'. Cheers.

[@SkylaneGuy]

Have to agree. Much as I enjoy Trent's videos, he's obviously getting compensation in some form or other from the various companies whose products he raves about on this vlog. There's nothing wrong with that as long as he discloses it. He SHOULD be compensated, as he's a terrific marketeer/demo pilot. It would add greatly to the integrity of his brand if he would be more open about it. It would be very easy to do, and what is the downside? People going to start calling him a shill for Kitfox/Rotax/Garmin/MT? Highly doubt it.

[@hairynuggs]

I dont know about anyone else but I think having the 360 cam just in the seat next to you would be awesome af

[@shawnmenzenberg6442]

That appears to be a full 360 barrel roll on the intro. How often do you barrel roll it? Great video as usual.

[@KaDaJxClonE]

That is an aileron roll. Barrel roll is basically a back flip but in a plane. That was done using an older engine, and it will starve while inverted, so he could only be upside down for a few seconds before the engine shuts off. His new plane is EFI so it should be able to just fly upside down. He doesn't roll it very often, or at least he doesn't show it in his videos.

[@hotrodray9884]

barrel rolls are 1g manuvers and the engine and airplane dont know that they are upside down or rolling.

[@shawnmenzenberg6442]

1 G was my understanding. Like Bob Hoover does with a cup of tea on the dash. kzbin.info/www/bejne/jGrTp3qVj7ihecU Not an aileron only roll that involves true inverted gravity flight. The question was for Trent because it appears to be the Freedom Fox performing the maneuver.

[@jasonhornady5297]

Hey Trent. Can you explain what a constant speed prop is and what the benefits of it are compared to other styles? The video you made of the ground loop “monster” was a great video. The way you explained it was super easy to understand. Thanks for all the great videos you put your hard work into!!!

[@zolotiyeruki]

If Trent doesn't reply, I can hopefully shed some light. A CS prop has a mechanism to change the pitch of the propeller blades mid-flight. A fixed-pitch prop is usually optimized either for climb or cruise. If you have a cruise prop, your takeoff performance suffers, but you get higher top speeds and cruise efficiency. A climb-optimized prop will get you off the ground quicker, but won't give you such good cruise performance. A CS prop gives you the best of both worlds, but is also a bit heavier, more complex, and more expensive. If you have a traditional carbureted engine, a CS prop will give you a third knob to manipulate. Trent's setup, with a fuel-injected engine and an EMU that manages the propeller pitch automatically, brings the knobs down to one.

[@jasonhornady5297]

Awesome, thanks guys!

[@jeffhoser7717]

I'm really curious how you " dnynamically balance in place " a prop ! ( I have some ideas of my own but they're based upon dated tech ) BTW I see your KF and new engine/prop combo performs pretty much per reality i.e the faster you go the more fuel you burn to ovear come the increased drag component . I suspect that "single-lever" control is a gas and much better than the old mechanical throttle/prop hooks . All thats left is seeing what essential equipment you can move aft to improve the CG ! Looks like a nice flying aircraft ! Love to get my hands on it !

[@VNtergon]

google DynaVibe, its the device that most use when balancing a Rotax powered prop. Its basically like a balancing a wheel for a car - you spin and see where you need to add some weights.

[@wernerwillemse3602]

Love your vids Trent, but are you honestly sure your elevator stalls before your main wing does (7:52)? That would cause the plane to be dynamically unstable, i.e the stall would not tend to self-correct... That would get a lot of absentminded pilots killed, so I believe Kitfox would have ensured the main wing ALWAYS stalls first....The only type of plane in which the elevator stalls before the main wing, yet you retain dynamic stability, are Cunard designs, where the elevator is in front of the main wing, like the Beachcraft Starship, LongEZ, Piagio Avanti etc...

[@bryanknight9147]

The pitching moment of the wing and the cg forward of the wing are both pushing the nose down. The horizontal stabilizer is flying upside down, keeping the nose level. If it stalls, the plane will nose down. With a canard, the wing and stab (canard) are both lifting, hence the improved efficiency. If the wing stalls before the canard, the plane will pitch up, exacerbating the stall, so canards have a static angle of attack to drive them toward stalling first.

[@wynnfpv]
