Re: reflex

Chris Walterson
 

Thanks Jay-----------  I have the plus 1 degree in the canard so I will go with your suggestion.  A question for the tri gears with the flat canard.  How do you set up your pushrod tubes for the bellcranks on the elevators?. Because my canard is flat the bellcrank connection is lower than the top of the fuel tank, and NO, I am not notching out the tank. It will almost impossible to bend the 2024 aluminum tubes, so I was thinking either use 1/2 inch x .035 4130 and either bend, or notch and weld to what I need, maybe even going past the bellcrank and coming back. Something like  half a Z,  or ,use a 1/2 inch bolt, bend it to the proper angle and then fit it and slide it into  some 2024 and hard rivet it in place.  I need about 30 degrees to make it work. I think I saw in one of the newsletters they had some type of mechanism on the canard and the control tubes went to this and then back to the bellcrank, but there  has to be easier way.

 Any thoughts.  Thanks------------  Chris

Thanks Jay, we had fun.  I was surprised at the lack of snow this time of year. It’s gonna be a dry summer.

Yep it’s still Sierra Sludge/Concrete unless you hit the slopes right after a deluge, then it’s pure puff.

Good flying to you!

Re: Your Opinion

Mike Dwyer
 

I have had carb ice once.  75F day.  Turned base, pulled the carb heat and the engine died.  I always try to stay high enough to glide in.  Squeaker landing and made the turn off I had planned.  Bob Hoover would have been proud.  Started the engine again in 5 min.  The next week I installed my carb temp gauges.  Now I don't even pull carb heat unless it shows near freezing.

One note.  I had removed the 4 into 1 crossover exhaust and installed 4 into 4 system.  The new exhaust doesn't heat the carb and case like the original.  Much cooler oil temps.  I'm sure that was the main cause.

Fly safe,
Mike

Hello everyone,

I hope y'all had a great bringing in of the new year. 

 

I've attached an article I read about once every five years or so regarding carb icing. 

We all know about carb ice and the danger it poses.  I experienced it years ago in my then Aeronca Chief when, in the summer, the engine stopped producing power on final.  At least it would not throttle up when flaring to land and stopped on touchdown.  After setting a bit she started just fine...by hand propping of course. 

 

The highlighted area toward the end of the article gets my curiosity up and is what I would like your opinions on since many of you are much smarter than I.

The reason for asking is that somewhere in the 90's I had the throttle shaft, throttle plate and intake manifold teflon coated on my Quickie and this article is where it all started.

 

One hot humid day back then while looking down the carburetor with the engine running I was surprised at the amount of water that was forming on the throttle plate, the size of the droplets and the time it took for them to run off.  Onan carbs are on the top of the engine as most know.

I found a company in Indy that did industrial teflon coating, Keco Coatings, and they are still there and this is their website https://www.kecocoatings.com/coatings/teflon/

After the Teflon coating was done the water still formed but with a notable difference.  The droplets were miniature sized and it was like a contest to see who could run off the throttle plate first.  Very impressive.

 

I've never sought the opinion of others regarding this article but knowing the breath of knowledge among you Q guys I thought I'd reach out and see.

 

Thanks for taking the time.

Re: reflex

Jay Scheevel
 

Heavily dependent on your decalage. High speed cruise and I use full reflex trailing edge down (6 degrees), but I have -1.5 decalage on my wing setup, meaning my wing is 1.5 degrees leading edge down relative to canard. I almost never set reflexor trailing edge up.

Those Q drivers that have positive decalage setups almost never set reflex to trailing edge down. They always fly with reflexor trailing edge up, for the most part.

I mounted my verticals with reflexor neutral and ailerons in trail. Works fine.

Re: Your Opinion

Terry Adams
 

Keith,
I have a plane with mechanical (Airflow Performance) and a plane with electronic (SDS) fuel injection so my opinion may be limited.� I especially question the sentence in the article "
Fuel-injected engines also mix fuel and air, but sometimes by misadjustment, wear, manufacturing or design defect or material failure, fuel is able to leak through a seal that separates the fuel from the air in the injector servo".
Not likely.� This definitely is not happening with electronic fuel injection in that typically the fuel is never in the induction system until it is injected in the cylinder.� This would be a long shot on the Airflow Performance even though the fuel is technically in the servo then injected directly in the cylinder after the fuel divider.
Slide throttle "injectors" like the Ellison or AeroCarb are a whole different animal.

Re: Your Opinion

Jay Scheevel
 

Hi Keith,

 

Thanks for the link. Interesting stuff about the Teflon. It certainly has the potential to get the droplets much smaller. Not sure if smaller droplets would keep them from freezing though. Just might make it a more uniform coating. When it goes from liquid to solid is a function of primarily temperature, but there are a few other factors associated with agitation and even electrical charge, but the primary influence is temperature and to a lesser degree pressure.

 

It is interesting to hear that you encountered your serious carb ice issue in the summer. I also had a similar experience flying from Winona Minnesota to see a friend of mine in Lafayette Indiana in June a number of years ago. I was flying down the Mississippi river, maybe 2500 feet AGL and I noticed I was having trouble holding my altitude, as I kept trimming it up. I had a constant speed prop, so revs remained constant so all sounded good, then I glanced down at the MP guage and saw like 15 inches! Yikes. I hit the carb heat, and almost killed the engine, probably when a big chunk broke loose. This was a big Lycoming 540 with the intake buried in the oil pan. It was in the mid 60’s (F) outside and thin overcast about 1500 feet above me. Not when I would expect ice, but there it was.  Of course there are other possibilities:  Maybe planes flying to or from Indiana are more prone to ice than other planes.  😊

 

Happy New Year, Keith.

 

Cheers,

Jay

Hello everyone,

I hope y'all had a great bringing in of the new year. 

 

I've attached an article I read about once every five years or so regarding carb icing. 

We all know about carb ice and the danger it poses.  I experienced it years ago in my then Aeronca Chief when, in the summer, the engine stopped producing power on final.  At least it would not throttle up when flaring to land and stopped on touchdown.  After setting a bit she started just fine...by hand propping of course. 

 

The highlighted area toward the end of the article gets my curiosity up and is what I would like your opinions on since many of you are much smarter than I.

The reason for asking is that somewhere in the 90's I had the throttle shaft, throttle plate and intake manifold teflon coated on my Quickie and this article is where it all started.

 

One hot humid day back then while looking down the carburetor with the engine running I was surprised at the amount of water that was forming on the throttle plate, the size of the droplets and the time it took for them to run off.  Onan carbs are on the top of the engine as most know.

I found a company in Indy that did industrial teflon coating, Keco Coatings, and they are still there and this is their website https://www.kecocoatings.com/coatings/teflon/

After the Teflon coating was done the water still formed but with a notable difference.  The droplets were miniature sized and it was like a contest to see who could run off the throttle plate first.  Very impressive.

 

I've never sought the opinion of others regarding this article but knowing the breath of knowledge among you Q guys I thought I'd reach out and see.

 

Thanks for taking the time.

Keith
