The XP-360 is built from Superior parts which are almost all FAA-PMA replacement parts for any Lycoming IO-360. The one difference is roller cam/lifters which is a great improvement. In short, it is nearly identical with a few modern improvements.

There is a comment below that answers most of your questions. Garmin doesn't control any engine parameters, it is mechanical fuel injection. The wing starts to get mushy in the high teens, in my opinion.

No, less noise than a metal airplane for sure. (RV)

The kit was discontinued in 1999 but there are a lot of kits that were never completed. The year of the airplane is the year it gets it's airworthiness certificate.

@@TomMcNerney Ty! Beautiful plane, congratulations and enjoy it!

Blowing up on Saturday would suck... I was saving it for Sunday, which ended up never happening... Bummed.

Thanks! It is running great and is actually painted now. Should have some great photos of it soon from an air/air shoot we did. It is awesome!

Jimmy, I see why you enjoy yours so much now. Hopefully you'll show some more of it on your channel. Save the 310😊

@@TomMcNerney Gorgeous.

@@TomMcNerney IFR or VFR only ?

@@C172Pilotdude well, it was a complete Garmin G3X panel but I don't think it has a certified navigator at the time. That was 10 years ago. It's still flying but I don't know if the panel has been updated. I would assume some things have.

No it's manual, but that is the first flight of that engine and airplane. Break in procedure requires maintaining high power and full rich to keep the CHT as low as possible. New rings have high friction until they seat in.

@@TomMcNerney Oh, ok... very cool Tom! I just started PPL training. Congrats on your new plane sir.

Yup, new airplane, new engine.

Because it was an "all RV" formation and I was in my Lancair. Plus I had a job to do which dress formation to help line it up.

@@TomMcNerney ah, makes sense. Excellent job, regardless. I wish there were more videos of the flyby from the stadium but your cockpit video was superb

I made that one, and all the parts around it. Google N91CZ plenum and you'll find one that Chris Zavatson makes. You can make it work with his diffusers. It is a rather complicated installation on an already flying airplane.

@@TomMcNerney thanks for the info, I here they really cool everything down, thanks again, Steve

Thanks!

Was 9 years ago. Had a XP-400, probably 220-230 hp. Has a 390 now. 240 KTAS max.

@@TomMcNerney IO-390? Those are about 215hp stock, so I assume you're pushing a lot more than that to hit 240T.

@@oisiaa no not really. The 390 with 10:1 compression dynod about 225 hp from memory. I have screen shots of 240 true at 2700 rpm. The airframe is heavily modified though.

Well, I can't say for sure until it is painted. The primer is uniform but not smooth (compared to paint) Also without gap seals we were seeing about 200 KTAS as is. I expect that will go up 5 to 10 with paint and gap seals. Maybe a little more. On my other airplane I got 7 kts by adding gap seals. This airplane is scheduled to be painted in a month or so I think.

@@TomMcNerney Cool. I just subscribed to you to keep up on this. I'd love to see a future video on climb/cruise performance.

This was the first flight of this airplane. The system had a slight internal leak in one of the main gear actuators we found later. The cylinder wall had a scratch in it. After the repair it holds pressure like it should. The pump runs based off hydraulic pressure switches so if it bleeds down, the pump runs. That is what the light indicates. I think the plane has 60 or so hours now and no more hydraulic issues.

@@TomMcNerney Nice design. Same as the Pipers, although you usually saw it coming on to keep the gear UP thanks to leaky actuators or valves. Beautiful airplane, thanks for sharing.

Well, I wouldn't ever switch to something other than a Lycoming, unless you want a massive project over a flying airplane. For all of the stuff you'll have to develop on your own, you can buy a ton of 100LL and the Lycoming of your choice. I put a 390 in Unleashed (see other videos) and can hit 240 KTAS at 7500 DA.

@@TomMcNerney thanks for the info, appreciate the reply, love your plane

Thanks! This was the first flight on the airplane and new engine, so this was part of the break in which normally has high CHT. That being said, it peaked about about 425 from memory, then settled down after the first 45 minutes or so. Took it 10-15 hours of hard running to totally break in. Only first flight issue was an alternator belt that could have been a little more tight. That was it. All good. Plane has 60ish hours on it now I think.

I used my Contour camera (out of business now) Race Render software to overlay GPS data and then I edited in VideoStudio.

@@TomMcNerney Thank you very much!!!!

This is a kit aircraft, the kit was sold in the early 90's. I recently completed it after other builders had stopped working on it. The legacy came out in 2000.

About 2500 hours over a couple years, and the project was partially complete when it showed up... Lots of work.

Thanks, sorry for the slow reply, just seeing this comment. Although many view me as an expert on these aircraft now, I don't feel that way about it. I don't know how much I'd really have to offer. I participate on the Lancair forums but generally everyone is quick to criticize, or they don't understand the benefits of why I did something different. I tend to keep more to myself now and just keep building. The Super Legacy is next and almost done after 6 years.

@@TomMcNerney Thanks for the reply Tom.. Ha ha, I have noticed a trend: If the first posted reply is a (+) one, then the rest generally remain (+) with constructive comments. However if the first response is (-) or critical, then the thread is doomed. I feel we have become sheep or worse, lemmings :D

Tony, see my most recent video which is another Lancair 360 I just finished last year. That gives you another perspective. It is a helmet mounted camera, but they don't give you a true point of view perspective. Visibility is fine, although on the ground it is more like a tailwheel, I look around the side of the nose, not over it. With a big tail, approach at 90 kts, slower once you really know the airplane. Both this airplane and the last one I finished have the big tail. I own one with a small tail too. There is a big difference, but the small tail is fine if you're not a bad pilot. The pitch authority in the flare is the major difference, and a larger CG range with the big tail.

@@TomMcNerney Thanks Tom, much appreciate the reply! I did check out the 2021 build first flight.. I'll put a note there..

Superior Air Parts XP-360 with 9:1 compression. 195 hp from memory.

sorry - found it end of video

Not really. It's more stable in pitch, but only if you keep the standard wing length. The extended wingtips hurt you 90% of time actually. The stall speed might be a fraction of a bit slower, but not worth what you loose in drag on the high end.
