Trailing Edge Fences

nosedragger48154
 

Hi Gang, finally got home and went thru my archives.  Alex Becker back in 2011, posted an article on this for the Cozy and LongEz from Klaus.  Not sure, but I think that the sizes he suggested may be a little big for the VariEze.  If anyone is interested in the email that Alex sent out in 2011, I can repost/forward it.  Good read.  Also when I went thru my old posts there was a lot of good feedback on the advantage that the TEF’s did for the operation of our aircraft.

 

Sincerely,

Mine are Oversized, but work really well. I have the patterns around here somewhere.

This plane had serious handling and stability issues when we bought it, including dutch roll on final. With the LE Vortilons and these TE Fences, and other things, it handles very well now. I believe it is just as the designer wanted it to handle and behave.

TEF on a VariEze are well worth the trouble. They changed the slow flight characteristics dramatically for the better. The little VariEze wings just didn't want to quit flying. The TEF's make the little wing fly like a much bigger wing.

My cylinders suffered an early demise with fairly serious scuffing of the walls.  I believe this because there was gritty dirt in the inside of the manifold pipes.

 

I think a well installed air cleaner is important! I might add that as part of the rework of the filter adaptor I reshaped the 180 deg bend and picked up 150 rpm static even though the new cylinders and pistons are 8.7:1 instead of the 10.5:1 that were on the plane. I expected less power from the new cylinders.

Well, good luck on the red light, Bob.
People can ignore a lot of things.

Once I had a listing for a FLASHING
red 12 VDC light but I have misplaced
the information.  
I am going to check Mouser, Digikey, and
McMaster-Carr.

Bruce,

It seems that pin 23 is an auxiliary audio input. You can’t just connect a switch to this however. You will need a device to emit a tone to your 220 through this pin. Others on this list will probably be able to point you in the direction of that device. It can be as simple as a tone or as complex as language saying something like, “Hey, dumb sh## close the canopy”.

Took my air cleaner off to see if the additional air flow would help cooling.  The engine ran poorly with weird throttle response.


Re: buzzer for the canopy/nose gear/throttle warning system

ma_cozy_flyer
 

I've been rethinking the gear/canopy warning on my Cozy 3.  I originally used a Sonalert for the buzzer and it is fairly loud.  But, with a noise cancelling headset I often can't hear  the aural buzzer.  I've also found that the continuous-on red warning light doesn't always get  my atttention. One thing  I'm planning to do is to make the red light flash on and off. 

I've got another idea too.  At Oshkosh this year we attended the evening session where the finalists for the Founders Innovation Prize for Loss of Control prevention innovations gave their presentations for their entries.  As it happens the "in thing" these days is to use a warning pathway that's different from the visual and aural ones.  The prize winner used buzzing haptic inputs in the seat cushion to trigger the alerts.


 So, I'm thinking of implementing an intermittent haptic "butt" buzz warning to the Canopy/Gear warning circuit.

Lee:

I had a similar situation to yours when I installed ADSB out a couple of years ago.  See the attached before/after photos.  At the time my Terra Mode C Transponder was no longer supported and was getting long in the tooth.  So, I wanted to do a 1090ES solution.  I went with the Stratus ESG Transponder and also changed out my Terra Comm radio with a Flight Line FL760A comm.  The FL760A fit in a panel hole I freed up.  It was a pretty easy installation as the Stratus ESG fit exactly in the space formerly occupied by the two Terras.  I also recouped some of the cost by selling the Terras.

I purchased the Stratus ESG along with a wiring harness from Aircraft Spruce.  I mounted the WAAS GPS antenna in side up in the nose.  It works great!

At Oshkosh this year I attended the Forum by Jim Weir of RST Engineering.  It turns out that Jim can provide the Stratus ESG at a pretty nice price.  ( No, I don't get anything for the plug).  Wish I had known about it when I did mine.

You can fly without one but don’t taxi without one. A canard has the front wheel throwing dirt back there.

 

My Cozy has a K&N filter that was installed with no gasket and not a good flat mating surface or even four bolts between the builder’s (not me) home brew glass filter adaptor and the throttle body.

 

My cylinders suffered an early demise with fairly serious scuffing of the walls.  I believe this because there was gritty dirt in the inside of the manifold pipes.

Aileron balancing

josrph berki
 

I am trying to balance the ailerons per Long EZ plans and I cannot find the max finished weight for the aileron.

I glassed a tube to accept a 3/8” ballast.  I got it close 1/8”(trailing edge down compared to leading edge)  but am concerned with the weight of the aileron.

If it is heavy is it prone to flutter?  What finished weight is acceptable with paint and hinges?

Can ballast be added to the CS 132L bell crank which  is inboard at the wing root to balance the aileron?

Thanks for any input.

I’m sure you can’t find 2 (or more) conflicting answers to the same question on any myriad of FAA official sources, POC’s, forms, records, databases ect... I’m also positive every answer is laid out in clear and conscious parlance in the most obvious location. O and it’s also been my experience that information is updated in a timely manner. That said, great original post, about this time next year I suppose there’s going to be a lot of GA aircraft due annual AND ads-b for sale at a bit of a discount?

Ok, I had the impression that 1090 was sufficient, and the 978 was a USA
only thing and not sure why it exists. So now my question, is 978 required?

Of course, ask here rather than the FAA web site. Wouldn't want any

I use a K+N air filter - I don't recall the model. The ones that I tried prior to that reduced the top end by several hundred rpm. Just calculate the required airflow at max rpm for your engine. See the filter specs to determine what pressure drop a candidate filter will require for that flow.

Re: ADS-B 2020 compliance experience

Lee Devlin
 

You're correct, 1090ES is all that is needed to be FAA ADS-B OUT 2020 compliant, but some 978Mhz UAT solutions such as the Uavionix products rely on eavesdropping on your Mode C transponder in order to be able to transmit the barometric altitude  because they have no other electronic interface to monitor altitude data.

In the U.S., 978Mhz IN is important because it provides weather data as well as traffic data from aircraft whose position is only reported from Mode C radar responses to FAA radar and repeated through the 978Mhz ground stations with their GPS coordinates.

Re: New engine /cooling

We have deflectors on the bottom cowl but they were installed when we had a carb and air cleaner. We no longer have either. May consider a change after a few more hrs of flight time / break in.

Thanks for the bar suggestion. I’m going to do that right now.  Cheers!

We don’t feel we have a heating issue, a slight balance issue ( so far 28 degrees difference) when comparing all 4 cyl. Break in and injector balance should help here.

Climb out. One can make the climb as fast and steep as they like. Trading altitude for speed is the preferred way. We are not overheating anything on climb out.

Response;
Screen is alum 1/8 hardware screen. Nothing fancy. Form it around servo opening and secure with ss hose clamp.

First let me state we are not flying LOP as we don’t feel the engine is broke in and the oil consumption has not settled in..

We do not like flying ROP. We will fly LOP when engine is broken in. 
On the old engine with 1700 hrs we ran LOP above 5500 ft and fuel flow was 6.2 approximately, speed averaged 158 kts. Change anything and these numbers will change.

We fly with dual plasma III. Bendix servo and std injectors. 
20 degrees BTDC.  C/R is a secret.
We will go to Airflow when we have all the data for sure.

What is your C/R and ignition timing? What type fuel system? You need to be at 20° BTDC  maybe less if you're running a higher C/R. If your have injection, do a GAMI spread test and see how well your cyl’s are balanced. 
And as Jay said try LOP,   20°-40° LOP will cool things off nicely if the system is balance well.

Hi all, let’s talk new engine and cooling.


This will have a lot of info. If you respond please keep your comments on subject.

Long EZ, 12LZ Curt Martin & Dave Fife

Facts: new engine IO320, NEW jugs, pistons, rings etc. There was other work on the engine to satisfy our wants, they were all done correctly per Lycoming but I will not give away our secrets.

12 hrs so far, running engine hard per lycoming to break it in.
It is still consuming oil but within normal limits.

Latest testing numbers:
Flying showed #2 was hot around 418, others in the 370’s. Oil 218.....

After 10 hrs We decided to close up some baffling around the in cowl exhaust pipes.
Test flight at 4500 ft, 2500 rpm, 7.8 gph.  
#1.    381
#2.    418
#3.    356
#4.    377..   This cyl was the leanest according to Dynon with bayonet probes, all were quantified for correct accuracy.

Oil temp 208.
11 hrs....

Better but not good enough.

Removed K & N, cone type air filter, installed 1/8 “ screen as Doug Kouri has done.
This really opened the NACA cooling updraft.

Altitude 3500 ft, 2500 ft, 
10 gph
#1.    345
#2.    349
#3.    348
#4.    380

Oil. 201
Big change,  hot cyl changed from #2 to #4.  We attribute this to more air flow.

Leaned to 9 gph,  3500 alt, 2500 rpm

#1.    356
#2.    357
#3.....    356
#4.    384.       A net difference of 28 degrees between hottest and coolest.

Oil 201.   Better again.

So my questions.  
Do we fly without air filter? 
Do we open the baffle around #4?
What else?

What we will be doing:
Put more hrs on the engine.
Fly a little higher and lean a little more?
How lean, per gph and temps?

Once we have more numbers we will be going Air Flow and discuss with them.

Thanks in advance for you knowledge and facts.
