Beautiful plane, thanks for this video! It looks like they extended the Legacy's vertical stabilizer and added a ventral fin too, although they missed a chance to improve the aerodynamics a bit by squaring off / sharpening the curved bottom profile of the rudder. Do you know if they had to rework the front landing gear to accommodate the engine? I wonder how this mod affected the weight. I'm also curious if they added any carbon fiber stiffening to the flanks. It's a shame they don't make the Lancair Legacy kits anymore, they were one of the sexiest kitplanes ever produced. I hope you get a chance to do part 2!
Very interesting. I don't understand why it's commonly accepted, in early last century the shift from air cooled to watercooled airplane engines were made practical thanks to glycol. Why is that? I don't get it.
Too heavy, too complex and too many hassles selling, all in all too many “too’s”! There’s many reasons why very few use oddball engines compared to the proper A/C engines.
I’ve owned a few WRXs and a few STIs I would never fly in something with a Subaru motor. Lots of crank bearing failures and ringland failures . I honestly question the design of the horizontally opposed engine. Rings are not going to wear evenly.
One guy in my videos has over 3500 flight hours behind EJs. No failures. Ring land failures indicate detonation. That's not the engine's fault- too much boost, too much timing, too lean, not enough octane are the usual causes. Rings mainly wear from gas loading and we don't see uneven wear on Porsche, Continental, Lycoming, Corvair or Subaru engines, even with high time. Not sure where you are getting this idea from.
@@rv6ejguy If the ringland failures were due to detonation why did Subaru recall several engines for defective ringlands? Same thing goes for the crank bearings those were recalled too. I had a crank bearing failure at 18k miles with a bone stock EJ257. I’ve seen several other failures too throughout Subaru groups I have spoken with. You’re going to be flying one day at that engine is going to go pop. You’ll be saying, damn that guy from the internet was right.
The ring lands were not defective. Subaru issued a Stop Sell order in MY2009 STis after multiple engine failures caused by improper ECU calibration and subsequent detonation. Detonation is the #1 cause of ring land failures. I've been building turbo engines for 40 years. Seen lots of cast pistons broken from that. Subaru also had a number of oil pump pickup failures resulting in destroyed bottom ends around the same time. The smart engine builder knows about these things and takes steps so they don't cause failures. Lots of "tuned" STis fail because the tuner doesn't know what they are doing. This is why OEMs don't warranty most modified engines. In aircraft, we don't push boost anywhere close to even the OEM factory limits. Most are running less than 7 psi for takeoff and maybe 5 psi in cruise at most. All makes of engines have their issues.@@Dave-so7sf
@@rv6ejguy what I see in the video is the first test flight of a radical new design four engine aircraft from a relatively small grass airstrip with repeated low fly bys and bystanders. Halfway through the video I was asking myself why would anyone take such risks? Testing from one of the many readily available large fenced public use airports with multiple longer wide runways and concluding with a single approach and landing would be much more prudent. In aviation, the unnecessary and the convenient are invitations to an accident.
What an amazing view when this plane flies past and into the sunset! I am amazed at how smooth and easy it flies....the sophistication of this plane is undeniable, yet this is really a piece of art that looks so well that it might appear easy if I didn't know better!... I am utterly stunned at how good this looks! Nice, nice job...well deserved accolades all around!
From what I understand,the first flight was unauthorized. The test pilot was only supposed to taxi the plane. Instead he took off and flew for, I think 500 feet.
This was the first flight and it was planned and intended. Tom Hodgson is the builder and pilot. I just talked to him last week on the phone. Hopefully back in the air within the next 8 weeks or so.
To scale AFAIK. Aircraft is being worked on now and Tom hopes to be back in the air in less than 2 months if all goes well. Will try to post another video at that time with more details and photos.
I talked to the builder and pilot a couple days ago. He'll supply more info, photos and video when he's ready to resume test flying in a couple months. Repairs and minor mods are coming along well. He has a full time job flying Falcon 50/900s which doesn't allow him as much spare time as he'd like to work on the B29. Be patient, more to come. @@timjodice100
I am stunned and amazed at the same time! Such a cool build! I would love to see the cockpit layout. I am going to guess it's not very comfortable in there?
The work he has done is AMAZING! I heard he had an accident, but everyone is okay. Will he be able to get it back up and running? I would love to see this plane! Wow!
Some good advice at the end. Better to build and test the motor first before embarking on the build of the fuselage. I am sure that is what Peter will do. The Lilium Jet project is also of interest here I would have thought.
