WAR Corsair Progress Report 1/14/2025

[@jerryclayton4616]

Things are looking great… can’t wait until it’s finished and ready to take to the air again!

[@Dynodon64]

Thanks

[@supernovaVII]

I was watching a B17 flight training video and noticed that it had a tailwheel locking lever that enabled the tailwheel lock for takeoff and then as the B17 moved and the tailwheel moved to center the lock engaged and there was a wheel lock confirmation indicator light on the instrument panel. Thought the locking indicator light would be good for your Corsair too.

[@Dynodon64]

That was always my plan to be able to lock it, even before it went off field. The real Corsairs had the same locking tail wheel too.

[@supernovaVII]

@@Dynodon64 Yes, I've followed your plans for the wheel lock, but on the B17 the locking lever is moved to lock position and indicator light illuminates when the wheel locking mechanism can actually lock the wheel, and the lock cannot happen until the movement of the aircraft positions the wheel in a position that it can lock. The important function is knowing that the wheel is actually locked.

[@Dynodon64]

@@supernovaVII Yes I know what you meant. Thanks.

[@kevinfrerichs8589]

That is a good idea for your muffler, to get even flow out both sides. Keep up the good work.

[@Dynodon64]

Thanks

[@brettwoodard167]

Making some good headway, thanks for the update Don!

[@Dynodon64]

Thanks for checking in.

[@xfirehurican]

*Geez, Don. Your metal fabrication and designs are genius and innovative!*

[@Dynodon64]

Thanks

[@dereksellars]

Thanks, Don. Coming along nicely! Slow for us, but not for you LOL Keep it up and I will be looking forward to more progress. Damn SNOW anyway, here in Iowa we have been lucky so far. Last year at this time we were dealing with around 28" of the wonderful white stuff. Take care!

[@Dynodon64]

Thanks

[@peterpatten5043]

Thank you for the concise upgrade for the projects and plans you will endeavour to put in place brother, good luck : )

[@Dynodon64]

Thanks for watching.

[@stevewoldanski4780]

I’m surprised you don’t have rags blocking your intake holes and plug holes. I enjoy your content and appreciate your ability to understand what all your systems do and how to fabricate what you need.

[@Dynodon64]

Yes, I should cover the ports, But I can see into them to the valves. When I get to working over them more, I'll tape them up.

[@guyoreilly5670]

Love following your progress. I wonder how different the W&B will be will all these changes. Lighter should improve flying, whenever you get around to that, no rushing.

[@Dynodon64]

It may move the CG back to far, but if I lose some weight, it's a win, win. I will re due the weight and balance when done.

[@thomasbullock6416]

Looking Good keep up the good work 👍

[@avgrphx]

Nice update. Have you ever thought of filming your work being done? Those types of videos generate a ton of viewership and engagement.

[@Dynodon64]

When I'm working, I just want to get as much as I can done. Filming will slow my work down.

[@Buckshothill]

Good work keep it up.😊

[@Dynodon64]

Thanks

[@geoffwatson6207]

Don, should be interesting to hear what the engine sounds like with your new exhaust.

[@Dynodon64]

I'm hoping for a deeper tone with the larger pipes.

[@Airsally]

Glad your losing weight. My son has a 1/6 scale RC corsair and he has to dump flaps to keep it from ground looping. His you tube chn is hecht speed he has several vids of it. The first few flights it ground looped with full flap. He has a 4 cly 222cc engine with a scale 32 inch prop. Ck it out.

[@Dynodon64]

I've been watching them. He also follows my channel.

[@WarblesOnALot]

G'day Don, Yay Team ! I particularly enjoyed the Bilaterally-oppositional Helically-split Spirally Baffled Exhaust System...; I dunno how it will go, hopefully the Typmannic-Percussion amplification-effect will be damped by the welding fixture joining the Hollow Spiral-Baffle into the Muffler-Can (?) Are you going to ventilate the Cross-tube at the centre of the Spiral Doughnut ? I;m thinking that a couple or 4 Holes of say 3/16" in at, the centre - maybe under the bifurcated-flow shortly after splitting the Stream..., and the same number of Holes out at the ends - ideally 180° around the Circle from the inlet Drillings - and 1/4" in diameter... So that the high-pressure Gas blows into the central Pipe, expands and flows out at each end thriugh the bigger Holes - close to the Exhaust-Pipes vented to the atmosphere, so the pressure there is less than at the centre & thus a bit of Exhaust Gas is being "processed" by that Volume in the Core of the unit...? It can't hurt, and might help ; so it might be worth considering giving it a try ? Such is life, Have a good one... Stay safe. ;-p Ciao !

[@Dynodon64]

Yes I will add the holes. I like your idea of making them larger as they move towards the outlet ends. Thanks.

[@WarblesOnALot]

@Dynodon64 No worries ! I think the Holes should be sized to encourage the Gas to want to go through ; otherwise that volume of space would be needed for the structural Geometry - but wouldn't be "processing" the hot glasses. I enjoy thinking about, and imagining Airflow, in the Wind-Tunnel of the Mind's Eye (!). Keep on keepin' on. Stay safe, ;-p Ciao !

[@Dynodon64]

@@WarblesOnALot I'm getting what you are talking about, and will use your idea. Thanks

[@Kickinpony66]

Regarding Bell Cranks for the throttle; you may check to see what is commercially available. So, with the reduction of nose weight, how much will it affect CG?

[@Dynodon64]

It may push it to the aft limits, I may need to move around weight.

[@Kickinpony66]

@ I also got to thinking about a manifold vacuum gauge. Whether or not you have one and if you think you need one.

[@downrangewarbirds]

Very cool updates. Could you build your own printed boards for the wing lights. Re-purpose the electronics just make a different profile and your own lenses?

[@Dynodon64]

Yes you could, but I [aid a lot of money for these, and they took almost two months to get.

[@jwoodyr1]

Don - I really hope I'm wrong but that muffler idea looks like a high-loss flow path (high backpressure). Momentum is lost when the flow is forced to turn. I hope it doesn't affect scavenging. Are straight (or gently-curved) headers with straight-through mufflers totally out of the question? Thanks for the update!

[@Dynodon64]

Flow will be reduced if you try to turn it at an angle like 90 degrees. This is not turning it. It is traveling in a straight but spiraling direction like a tornado. Straight pipe with inline mufflers is too long.

[@BudLiggenstoffer]

Looking good Don… I will be curious how far aft the CG moves with the weight reduction in the engine compartment… I’m sure the things you are adding will compensate somewhat but not sure it will be enough without a little lead wt in the nose somewhere??? Of course I don’t know where the CG fell before, so it might not be a big deal….. Just curious when you get everything built and installed what the weight difference will be between what you remove and what you replaced it with… But then again, the new replacement parts you are installing seems like it will be mounted farther forward than what you removed???? Will be interesting to know when you get it all done and do your new weight and balance… Keep up the good work…. I patiently await your next videos….

[@Dynodon64]

W&B was right where it needed to be. If I lose too much weight up front, I will need to move some weight forward to keep it from being tail heavy. I will re do the W&B when done.

[@richardbrowne3641]

The muffler insert baffle looks like a snow blower turn blade. 🤣 Is that muffler going be shaped like a VW Beatle muffler, Don?

[@Dynodon64]

It sure looks similar to one.

[@richardbrowne3641]

@@Dynodon64 I was just asking because I was thinking as your were explaining the construction of your muffler being like a VW BEATLE muffler. You could of bought one and modified it to fix.

[@edwardstephens247]

Is this a current video?

[@Dynodon64]

The date is in the discription.

[@Airsally]

Will you have a back up fuel pump? I am liking all the weight reduction efforts.

[@davidpoesr.2125]

The corsair an bear cat are my favorite two ww2 birds i fly giant scale rc ww2 birds i have a 120" blown up from a 93" ziroli corsair flys awsome yours look awsome in the air i was watching your first test flight wow it looked just like a real corsair on take off it looked a little funny with the left rudder but engine rotates counter clock wise an thats going to cause opposite torque. Its sad when i saw the nose over but wood an foam isnt as hard to repair than the aluminum frame as on the real corsair.an the up grades your doing is awsome you want to fly it an not spend 80% on repairs.

[@Dynodon64]

Thanks for dropping by the channel.

[@edwardstephens247]

Is this used as a baffle inside for a muffler?

[@Dynodon64]

Yes, it is the muffler.

[@davidpoesr.2125]

Hey Don what radial engine would fit in the war corsair an have enough power for it. I no the radial engine is way more money an maintenance but what hp an radial would fit an work.

[@Dynodon64]

Rotec Radial engines will fit if you make the cowling larger when building the plane, but they cost over $25k.

[@silvergemteam]

Beautiful work really shows there are men who not only keep civilization running but also remember it's past, I wanna ask you if You know, what happened to WAR replica company? Did they go out of business?

[@outlawflyer7868]

All that work in that engine when you could spent money in a tried and true, fuel injected aircraft engine. I said over a year ago. Put a verner radial in it. Why build such an iconic warbird to only out a flat 4 cylinder in it. This is just my opinion, but that engine choice has taken away most of airplanes nostalgic look and sound.

[@Dynodon64]

Those engines are all out of my price range. Plus, they cost more than the aircraft is worth.
