Hobbs Wiring

Joe Hood
 

My Hobbs meter isn’t moving. Does Hobbs connect up with oil pressure or straight to the master bus?


LS-1 canard

Bill Higdon
 

What year was the LS-1 canard first released?


How Much Cable Play between Rudder and Tailwheel in Q2?

Joe Hood
 

I have about a half inch of play in relationship to my tail wheel. This is still pre-Six pack, so cable comes from wheel to rudder. I haven't figured out where in the plans this number might be, anyone know?


Re: Facet Fuel Pump

Thanks for the video.  My Faucet solid state (currently $39 on Aircraft Spruce) is much quieter than both those examples In your video.  Which is good because I thought mine was loud before now.

As reported earlier my 20 year old Facet Fuel pump failed last week.  These things now go for $70 (auto parts store) but the BraveX (knockoff?) sells for $20.  I've got one flight in with the BraveX and seems to be nice.  It's virtually the same form fit and function as the Facet but it runs quieter.

I made a video so you can hear the difference in the two pumps when dry.  They are both pretty quiet when they have fuel to pump.  The video also shows the 20 year old Facet pump insides.  I'm always curious what's inside stuff so I took it apart.  The Facet previously did nothing when powered up but on the bench when I jumped the protection diode the darn thing started working and now won't quit.

Funny that today Facet advertises the pump as new "Solid State Fuel Pump" but it looks like 20 years ago it was also solid state!  Marketing...

We'll see how long the BraveX runs!

Thanks Joe! Wing root is another place for improvement. Both wing and canard to fuselage intersections are tough due to the diverging angles. I think it was Bob Farnum that took some interesting photos of the bellies of several jets at OSH (long ago). I suspect the secret to a few kts might exist in those photos.  Several of us also did some oil flow testing. I'm sure (??) Sam did so on his speedy machine.  Mine were horrible, as already shown, but that (oil) is another way to get some fairly good info - particularly if you don't have someone to fly and video for you. It is messy though!! :-)

I forgot to ask: Is that the radiator, P-51 style, hanging from the belly, behind the pilot?

Sam: Given how bad the wheelpant and wing root airflow was on my airplane, would be interesting to see yours.  Given your speeds, I bet it is massively better!

Thanks Dave!! I'm planning on FOD again this year and hope to hear about your latest paddling exploits!!  My governor told me that it is unsafe for me to be out in my kayak so I'm suffering a bit, but at least I'm safe.  Hope you drag Rodney along again too!

Great video! Really handy to know that my high speed taxis are not much different from another.

The ribbon hanging videos are interesting: Both areas with bad aerodynamics areas (wheel pants and base of the canard) were mentioned in the last Zoom meeting (but it's nice to see actual testing).

That is always a tough question to answer Ryan.

The final configuration performed fine - much better than a Revmaster, maybe approaching a Q200.  However; that does not tell the real story. It required thousands of hours to get it to work (yes, thousands, plural), the cost, and the limitations that existed after all that effort were absolutely not worth it. I fly behind a Lycoming now - ya, big old ugly dinosaur.  I fly whenever and wherever I want - including some places most pilots avoid. I pull the cowling off once every six months or so just cause it feels like a should.  The reliability and resulting peace of mind cannot be understated.  The cost of an aircraft engine (Lycoming/Continental) and bad-mouthing "ancient tech" are the basic tenants of those desiring an "alternative engine".- they are lies we tell ourselves. If you want to fly (soon & reliably) - fork out the dollars at the front end and install an O-200.  If you want to spend years tinkering, troubleshooting, scaring yourself to death, increasing your risk of significant injury or death, and spending MORE $$$ than an O-200 costs - go with an alternative engine.  Btw, having flown with a HAPI VW and Revmaster (and Rotax 503), I put them in the 'alternative engine' category.  

Not sure it matters but my opinions are based on twenty years of working on alternative engines and ten years flying behind aircraft engines.  So, not exactly an opinion based on a couple articles that I read.

Yep. They were from New Jersey and low time pilots. I also encouraged them both to trailer it as well but they knew better. “It’s a simple airplane and it should be simple to fly”. Get another Q and come on back!

Thanks Jim!! I appreciate that very much!

Yea, I got a call shortly after the accident occurred. They were flying in the late afternoon in early May. As I recall, density altitude at that time was around 7,500'-8,000'.  He relayed to me that THEY (at or over gross) managed to slam it on the runway TWICE at Belen (BRG) - he said "we hit very hard and went around" (both times). That resulted in something breaking which caused the elevator to freeze. They then flew it to ABQ to finish it off.  Given what I saw in the picture, I wondered if the canard/elevator were broken during those first two hits. If so, it is amazing that it held together for the 30 mile flight to ABQ.



Based on what I was told, both were from back east near sea level and had no experience with mountain/high density altitude.  I tried to talk him into trailing it home and learning to fly it in a familiar environment.

FW: Savvy FEVA 2.0 Exhaust Valve Report

Here is more information on the Exhaust Valve report that I sent last week. FYI. There is a link in here for FAQ’s

Savvy Aviation FEVA 2.0 Valve Failure Risk Analysis

View this email in your browser

 

 

 

FEVA 2.0 has launched!

FEVA 2.0, the next iteration of Savvy’s Failing Exhaust Valve Analytics, provides improved accuracy, regular reports and a new graphical presentation. All of our SavvyMx, SavvyQA and SavvyAnalysis Pro clients who had recent flight data uploaded to our SavvyAnalysis platform received a “Valve Failure Risk” report last week.

FEVA 2.0 uses machine learning technology to “learn” what combination of 34 predictor variables point to a higher than average likelihood of valve failure. This is possible because of the 2.5 million flights of engine monitor data uploaded to Savvy since 2014 and Savvy’s deep trove of maintenance data going back to 2008. You can read more about FEVA 2.0 in the FEVA FAQ.

Some of our clients who received the report were alarmed because they were not expecting it, and they thought it meant they had a problem. (The subject line of the email didn’t help, either.) We have fixed that, and have made the chart presentation more helpful and comprehensible based on feedback from you. We’re very sorry we alarmed some of you -- we do understand our job is to make your maintenance less stressful, not more!

We plan to send the FEVA 2.0 report to you weekly if data from five new flights has been uploaded to your Savvy account. We believe FEVA 2.0 is an important component of an engine condition monitoring program, and we encourage you to keep your engine monitor data up to date so that you will receive the FEVA 2.0 reports regularly.

If you didn't receive a FEVA 2.0 report, it is likely that you had not uploaded data recently. Use the button below to upload your engine monitor data and automatically receive FEVA 2.0 reports!

Re: Old Video - Subaru Q2

Hi Jon,
Thank you for that video. I remember videos of your SubeQ. You had a nice plane and did a lot of experimentation for our Q community. I really enjoyed your contributions. To bad the guy that bought it and his “instructor” smashed it at Albuquerque International within hours of buying it.  I remember the day it happened. As I recall they made several landing attempts at that huge long runway and still could not land it. He called me the day after and tried to say it was out of rig and I told him he should not even go there. Never heard from him again. 


Best,
Jim
