  1. It's the age, not the sex that fact Hunter is questioning
  2. Of course the boys and their ricers were all about the noise. I remember when blow off valves WEREN'T illegal, I saw an ad in a ricer magazine for a blow off valve proudly stating theirs was 25% louder than the competition 😄. At least they weren't hiding why bogans would install them!
  3. Well, like I say, most of its flying now would be low, where you wouldn't normally use the turbo. My original concern was basically that it might be hard to have a 100% working warbird if you couldn't maintain the turbo. As you see in the pics I posted, it's a not insignificant part of the aircraft. I guess even more so for the P38 since it is a visible part of the airframe. It seems the answer to my question really is that if the turbo isn't working, they just don't use it.
  4. I suspect people are just going to fly them sans turbo from the sounds of it. The up shot I suppose is you might be able to gain a few hp by simplifying the exhaust AND inlet by permanently removing the turbo. A bit of extra horse at low level would be just what the doctor ordered for an aircraft mostly flown at low altitudes at air shows 😎
  5. More on what's happening with current WW2 aircraft. This page tells me there are only 3 P47s flying with a working turbo. https://www.worldwariiaviation.org/aircraft/republic-p47-thunderbolt First I thought that supported what I was taking about. But then elsewhere I read there are only 4 P47s left flying! So then I thought, well 75% isn't a bad rate. But I'm back to where I started- that it is getting problematic. If you've spent millions restoring a war bird, it seems to me you wouldn't stop at the turbo, unless you just can't replace it.
  6. I thought it was more about pressure? In any case, the distance would help the air going back to the engine cool, on top of the intercooler. You see this with the P38 as well. Just doesn't seem to be easy to get it all up close the front. Unlike a car with its relatively wide front end.
  7. And this I guess is at the crux of my question - machinery that needs special alloys because of high velocity and temperature don't seem to me to be able last for a very long time, especially since they would be glowing red hot during normal operation. During the war it didn't matter but for 80 year old restored aircraft spare turbo chargers must be like hens teeth. And they're frikken HUGE! Hence my musing that heavy earth moving machinery might supply something adaptable. But even then, when you look at the plumbing of a P47, there doesn't seem to be much wiggle room 🤔

  9. Bloody hell! Thank goodness for jets!
  10. Good point. It was mostly about pressure altitude right? I guess the turbo would hardly be used at all in airshow settings. I remember seeing a lockhead constellation in Darwin, maybe late 90s early 2000s. From Arizona, flying around the world. Those turbos are geared back to the crankshaft or something aren't they for take off power? Something weird anyway. Those turbos would get a good workout I would imagine
  11. You mean swift supplies? I will check them out 🙂 https://www.swiftsupplies.com.au/
  12. I need to replace some bits in my undercarriage made of this. Yes, my build has sat around so long they need replacing 😄 Can anyone post a link to some 5mm sheeting I can buy in Australia?
  13. I'm not talking about WAS. I'm talking about IS. All those war birds you see at air shows that run turbo chargers, surely it couldn't be the original?
  14. Been on my mind awhile. in general, turbos are pretty high wearing machinery. If you have a P47, surely the original turbo charger wouldn't be serviceable. But unlike a lot of other machinery, you wouldn't knock up new parts in a machine shop. So whats happening there? Still lots of NOS to be had? Or adapting something modern from earth moving equipment etc?
  15. I'm finding his channel very informative. I can't help but absorb it. Lessons from others mistakes are powerful
  16. Welcome aboard guy!
  17. Cables, with a springy connecty thing. I guess for damping of major directional shifts. Also allows the wheel to swivel backwards when pushing. Bit of a pain, mind . The brakes are more or less hydraulically sound. Issue is I can't reach the right hand toe pedal. Hence I'm basically only turning left 😄 I've got a tip from a fellow Bushcat owner, and he's done what I've been thinking - bolting a rubber door stop to the toe brake pedal. This is more or less the one. A matco https://matcoals.com/product/tailwheel-dual-fork-8-pneu/ Anyway, this thread is more about showing him off (all my cars have been a 'he' for ever. So it will be with my plane) than fault finding
  18. Once I've nailed down the brake pedal issue. I'm starting from page 1 in the build manual to check everything but, bolt, split pin and cable. Then more shake downs. I'm in no rush anymore. I'm almost not even excited. So I can happily just taxi it for the next month before I get the final inspections down 😄
  19. Right now, it only turns left 😄 Brake design is woeful. Some tinkering is needed.
  20. I suspect that air was trapped in the park brake. Since I had to buy a quart of oil 🛢️ I may as well waste some. I will probably do a 'car' brake pump again soon. Lines are black unfortunately..if I ever replace them, I'll get clear for sure. Makes sense 😎
  21. Hey I bought a syringe 💉. Did the left brake first. When I did the right brake, damned if I didn't see quite a few bubbles coming up into the reservoir! Reservoir is on the right, so I couldn't see what was happening on the left. Note that I first set up the brakes several years ago, doing the traditional pumping method. So in a sense I've done several techniques as you recommended 🙂
  22. Don't worry about the motors, they are already, what, 90% efficient? It's the batteries where the next big leap needs to be. There is some hopeful news regarding sodium batteries. That should bring the cost down a lot. And increase safety. Weight is of course the next big issue to tackle...
  23. I have what I have. Which is a tail dragger ultralight. I find on the tricycle undercarriage Tecnam I hire, if I want to do a sharp turn, I press down down hard on the pedals and wrench the hand brake at the same time. Feels much the same turn as a Warrior with toe brakes. In the hangar is a, I want to say Australian Lightwing. So I will 😄 which is tricycle and cables and drums. I doubt it could stop as quickly as my setup, but I wouldn't care either. Just operate it within its capabilities.
  24. Yep, I actually think if I had a tricycle, I'd set up cables on a hand brake. Who cares you have to adjust it every now and then? At least it will be easier than adjusting drum brakes on a car, and they were hydraulic to boot- worst of BOTH worlds 😄
