This was fun and interesting to watch! In the late 1960s I had to make a small design change to the nose wheel steering on the Vought A-7 Corsair II, to force the wheel back to centerline when airborne. That was to make the nose gear trail in the wind until touchdown.
Looks great, tail wheel seems to be working fine, I have to mention, I’m hearing what seems to be a torsional vibration , when you power up from idle, and again , when the engine drops the rpm, just before idle.
I've always wanted to build a half scale A-26A (B-26K) Counter Invader (the vietnam version) In half scale it would be about the size of a Beach Barron... LOL! In that scale the body is about the same width as C152, would be four seater 2 in cockpit and 2 in back gunners compartment. Bombay would be for luggage, and would be powered by 2 Lycoming O-360 engines and be fully IFR equipped. I know I'm dreaming but hey...you started off your Corsair with a dream! And I cannot wait to see you fly it!
I really like your videos and appreciate your talent. Thank you for sharing your work with us. I would love to come and see it first hand. I’m based at KCAK and flew up to your airport one day just for fun. Then I realized where I had been.😂 I also see the gear door slop. I’m a little concerned about it at airspeed. Have fun, be safe.
It looks like you are willing to be patient and wait until you are completely satisfied with the operation of the tail wheel before moving on to the next item.

Best wishes, Sir!
When I was in the "Air National Guard, 68 to 74, (F102's, later F101B's, me, a weapons mechanic) , A crew chef, had authority to taxi/move the T33, trainer .Moving the ship, to avoid , a log jam, he had to gun it, he said, "I felt her get LIGHT, she wanted to fly",, I hope this for you,
A Japanese World War 2 pilot said that at low altitude the P-40 was very dangerous, at high altitude it was the P-51, but at all altitudes it was the F4U Corsair.
You are the Master, great job, She Wants to fly, keep your logs in order, and best of luck, happy landings, can't wait for that happy day. Taxi to the runway, speed until her tail lifts , test,
I have been following Dynodon for several years - close to 10 actually, excellent workmanship. Since he came up with the gravity powered foam cutter. I am very familiar with this design and Dynodon is mastering the whole thing. Keep up the good work.
Looks like it maneuvers much better now, can't wait to see it airborne. That will be an epic day 👍 Wish my grandfather was around to see this project...
Don, your craftsmanship is throughly impressive. CUDOS! As mentioned in another comment, i also notices youe left gear door looks to be flopping around a bit at taci speeds, Ixm sure you sre now aware of it and got plans to correct it. It wouldn't be good at take off speeds to have it bend from the air pushing it. Agian, Awsome and wonderful job!
I will look into it. The way they are made, there will always be movement with them. I think it has more to due with the prop wash hitting that side more.
Looks great, tail wheel doing the job. I have to mention, In the video, I’m hearing what seems to be, a torsional vibration , when the engine powers up from idle, and then again, as it drops rpm to idle.
I am watching every video so far, I can't believe the awesome work you do and how you solve problems like you do, great work and I can't hardly wait any longer for your high speed tail up taxi test and then that first flight will be the best day ever to see your baby in the air.
Slow and steady progress. I'm sure you'd like to get it up but refining all these pesky idiosyncrasies and nuances are very important. I mean you're building an airplane in which you're placing your little bod. Getting it right the first time is key. Love what you have done.
Great job Don, she turns on a dime now. Glad to see you’re taking your time and working through anything that isn’t perfect. Don’t let some comments about not flying it yet discourage you, you’ll know when the time is right to fly.
Great job, Don! You can't steer me wrong! (JOKE!) I can't wait for the final taxi to runway to see you fly! Just don't crash and burn. I will be very deeply sad.
Don I hope you have enough pitch on the prop. The aircraft looks just like the full sized one but I can sure tell how small it really is compared to the monster F4.
Not really. I bought an aircraft (MiniMax 1500R) a guy had been working on for over 10 years. It was 90-95% complete. He became afraid to do more than taxi it after his flight instructor was killed in an accident. He sold it to me cheap. I did first flight on it, which was also my first solo, and put hundreds of hours on her over a 6 year period.
Read FAA rules on experimental plane [ Advisory Circular (AC) 90-89C ]. They have to log so many hour before it can take off. Testing the planes equipment. I'm not sure of the exact hours, but I think it was 20hours before the tail can come off the ground and then some more hrs of limited take off speed with online bounce the wheels [not purposely taking off]. Then he gets his last inspection to fly. EAA also has all the info , if you are interested. Dons done a good job of covering every aspect from wing load to landing gear max load before folding. He even did a lot of testing on the engine mounts. I'm just wondering how many hours is the car engine going to handle continuous rpm, when he take it to Oshkosh next year.

So far so good.

Love your work. Keep it up!
Just brilliant!❤
Your Taxing And Plane is alot cool and i love your content of how your plane works and stuff its amazing! Keep it up!! ❤❤
Fly the damn thing already! He reminds me of my dad who would build really cool stuff but never do anything with it besides tinker with it!
I'm not legal yet to fly it. Taxi testing will continue until then.
Glad this worked out for you, thumbs up.

In the video, I’m hearing what seems to be, a torsional vibration , when the engine powers up from idle, and then again, as it drops rpm to idle.
Backlash in the gears in the gearbox. It's normal. There is a dampener in the geardrive for that. All Rotax engines have the same sound.

So… what’s next? Nice work. Glad it’s meeting your goal and expectation.
Keep increasing the speed until the tail lifts, then keep going until it lifts off. A little at a time.
It appears that is working very well.
So far I'm happy.
Cant wait :)
Nice tail steering ! video on landing gear swing next? Good job Don😊
I already have videos showing the gear swing, when I was adjusting the gear doors. Go back through my videos to find it.

Don I hope you have enough pitch on the prop. The aircraft looks just like the full sized one but I can sure tell how small it really is compared to the monster F4.
Prop was set at full throttle run ups, to get the desired engine RPM. It can always be reset if needed for flight.
I won't lie, this is cool as F
That sure us a pretty little aircraft.
Yeeeee
Wish it sounded a little meaner. Still got that lawn mower vibe.
I like it quite
falta muy poco compañero
Differential Braking may help a lot....
That's what I'm trying to minimize.
Looking beautiful. You did a fabulous job on that bird. When are you going to start high speed taxi/takeoff and runups?
I will gradualy do faster taxi speeds to work up to that point. A little at a time, until I get used to it's handling.
So when are we flying ... come come come now ! Lesgo !
hey im back nice video i dont know if you remember me but im back!

Forgive me for not knowing. Don, that looks like a solid (rather than pneumatic) tailwheel, do you think you could fit a larger pneumatic tire?
It is solid, that's what the plans called for. It's 4 inch and I could put up to a 6 inch on, but the doors would need cut out more.
Look at pneumatic four-wheel moving dolly tires
Nice....what scale is that??
Yeah great I've watched at least three vidios of you just taxing around let's make a vidio if you flying it already
It's called testing. It will fly when I am comfortable with it. I'm getting closer to that feeling now.
Hi can get the photos of build
Will it steer in the grass too?
Will probably require more breaking to steer.
you haven't flown it yet?
Not yet, just testing before I fly it. Everything about this plane has never been tested.
G'day,
Yay Team !
The Tailwheel Steering seems to be working as you hoped it would do ; well done !
Um, most of the time it sounds very quiet... - almost Lawnmowerish, when taxying under a bit of power ; and it's almost silent when idling...
But, apparently when you throttle back from Taxi-powee to Ground Idle..., it goes through a phase where it sounds like a Tin-Can containing a handful of loose Nuts and Bolts, tied to the Tail of a galloping Horse - and every Hoof is kicking the Tin in it's turn, beating a Sheetmetal Tattoo - kind of thing...(!).

Protesting at the

Overspeed the

Or is it some other
Cause & Effect
Going on...?
It sounds as if it might be
Potentially
Destructive of
Whatever is
Making those
Rattley
Noises...?
Or they may be harmless.
The conundrum has me mystified....
Such is life,

Prop slap, backlash in the gears. Same sound all Rotax engine have. There is a damper clutch like disc in the gear box to handle those vibrations.

Cool, thanks.
I had a fair bit to do with 2-Cylinder Rotaxes, aerotowing Rogallos ; and they could be a bit noisy - but we had 2-blade Wooden Propellers ; maybe the 3rd Blade multiplies the Noise (?).
