Hangar Flying / Emergency landings
« on: March 14, 2007, 03:11:11 PM »
I was practicing a simulated engine out with an instructor and was shocked that had the engine actually quit, I would have come up short!  This really shocked me (I have a lot of glider time, and never came close to landing short).  But, the winds were more than I had judged, and the windmilling prop had more of an effect than I expected.


It can be very helpful to practice these things before you need them.

My most humble suggestions:
1. Practice it a lot in Flight Simulator first.
2. Practice up high first.
3. If you have a field with 2 runways at about 90 degrees to each other, you can always abandon the procedure and land on the other runway if you are going to come up short.
4. Use the rule of a touch down point 1/3 down the runway.

Hangar Flying / landing lights

Has anyone ever installed landing lights in the nose of the wheel pants?

It seems like cooling would be good, and no reflection off the canard.

Hangar Flying / heat
« on: February 24, 2007, 10:23:44 PM »
You might want to use a 3" Turbo Bilge Blower from West Marine.

They weigh almost nothing, draw little amps. 12v.

Go to www.westmarine.com and search for Blower, Turbo Bilge 3IN.

Manufacturer is Attwood.  Mfg Part #1733-4, West Marine PN: 594002

Cost is about $34.00

Suggest you set this up to blow, not suck the air so the blower stays cool.

Hangar Flying / cell phone tie in to intercom
« on: November 13, 2006, 08:52:06 AM »
I have a Sigtronics intercom, and was wondering if anyone had ever tied a cell phone jack into one of the passenger headset plug sets.

It would be convenient to be able to plug your cell phone into the headset to be able to make a quick call in flight, while still monitoring communications.

Is this as simple as it seems, or are there impedence matching problems?

Hangar Flying / Featherlite contact info
« on: November 12, 2006, 04:19:16 PM »
Here is the Featherlite contact info:
Larry Lombard
FeatherLite
Box 781
Booneville, CA 95415


Nose strut price $85 + $12 shipping, $97 total.

I think thier email link is on the Links page, but they aren't quick to respond to emails.  Best to call them, but I can't seen to find their phne number right now.

You may need some help if you want to replace the strut.  It will take a lot of work to remove and replace.  The attitude that the plane sits at during the takeoff roll can dramatically affect the takeoff roll, so you want to trim the length correctly.

Hangar Flying / How to buy a canard
« on: November 02, 2006, 05:07:04 PM »
I'd highly recommend you go through the local EZ group or David Orr http://www.canardfinder.com/

IMHO:
If you LOVE building, then buy an orphaned project.

If you want to fly, but a completed and proven plan, recommended by David or experienced EZ builders/flyers.

And if it seems too good to be true, it probably is.

If I had to do it over again, I'd have bought a flying Vari or an 0-235 Long and put a 0-320 on it, and spent my building time going over the plane nose to spinner, fixing and upgrading.

Hangar Flying / dual controls
« on: October 03, 2006, 12:25:16 PM »
There are two reasons I'd like a dual throttle in my EZ.  

The first is to give give my wife and friends some basic flight instruction for educational/fun purposes.   Since the EZ needs little/no rudder for shallow turns, the stick and throttle seem enough.

The second is to give the GIB a chance to safely land in case the pilot is incapacitated (bird strike, medical).   It seems the GIB would stand a better chance with a throttle rather than waiting for the plane to run out of gas.

Landing from the back seat would be a challenge, especially for a novice.  Why add the additional task of making that a dead-stick landing?

So, in the second case, the purpose of the throttle would be to help make an emergency landing by the GIB more survivable.

Hangar Flying / fuel system
« on: October 03, 2006, 09:53:11 AM »
OK, I've come to the decision to put the electric fuel pump on the firewall.

It would be SO much easier to mount it under the pilot seat.

But my concern is that even a pin hole leak in the fuel line inside the cockpit with the electric boost pump running would dump a lot of fuel in the cockpit before I could shut it off.

This is not only a fire hazard, but 100LL is very noxious even in tiny quantities in the enclosed cockpit space.

So, it will be a struggle, and I REALLY didn't want to do it, but I think it's best to keep everything front of the firewall gravity feed.  Once I figure out this puzzle, I'll be glad to furnish pics to anyone who is interested.

Thanks for all the input.  I'm glad I considered all options before coming to this conclusion.

Hangar Flying / fuel system
« on: October 02, 2006, 09:43:09 AM »
Thanks for everyone's comments.  I was at Rough River Sunday... really awesome, and a huge motivator to push to the finish line.  

My wife came with me, and she LOVED the ez's, which along with everything else does make her THE PERFECT woman!

The only question remaining before I nail this down is whether the electric fuel pump should be placed ahead of, or after, the gascolator.

Some say don't pressurize the gascolator, and that you should have only gravity pressure fwd of the firewall.

It would be much easier to make everything fit if I could move the pump and filter off the firewall.

I'll make a final decision soon and then get on with finishing everything.

I had a friend comment that I should not put the fuel filter and pump forward of the firewall.  He's a bit of a Rutan purist, and believes a rigid line between the fuel valve and firewall is lighter, and less prone to chaff than a flexible line.

He also thinks pressurizing the line fwd of the firewall, and adding the associated couplings to put the filter and pump ahead, is asking for trouble.

I want to maximize safety.  I also see real advantages of placing the pump and filter fwd of the firewall.

I know this is my decision and responsibility, ultimately, but would appreciate your opinion:

Stick to the plans, or move it forward?

Great advice.  

Actually, I'm putting away my ego and desire and will have my brother fly the first 40 hours as he has about 600 hrs in Canards, including a first flight in a Cozy he built.  

We'll spend days working together to go over it nose to tail, not assuming any bolt is properly torqued.  First 20+ hours will be within gliding distance of the runway.  

We have a 5000' runway in Springfield, TN for the first flights.  Flat, open spaces, great place to test fly.

I hope to transition and take possession of the plane by early summer 2007.  Then slowly expand my radius of travel over the following year or so as I gain skill and confidence in the plane.

Still mulling over the placement of the fuel filter and pump.  Hell hole might still work if we can fab a suitable mount for everything so nothing interferes with the rudder cable conduit.  Opinions?

Yikes, I really wanted to put the fuel filter and pump in the hell hole, but it is a hard place to work, to get the flow right (pump below gascolator, no arched loops).  It may also crowd out the oil heat system we wanted to stick back there.

I'm now thinking about putting the filter and pump under the pilot seat, and change out the rigid aluminum fuel line from the pump to the firewall with flexible line from the fuel switch, to the filter, to the fuel pump, to the gascolator.

This puts the pump very low so it will gravity prime.  It would be a lot easier to inspect, service the filter or replace the pump if needed.  I would also not have to guess if the fuel pump is on!

I don't like the idea of more fuel connections under my legs, but all my components are very good quality, the mounts are solid, and I'll inspect often.  Any fuel leak would be bad, but at least I'd know about this one and be able to shut off the fuel, whereas a leak aft of the firewall may be harder to detect.

It is very challending and frustrating sometimes working on these planes.  Everything is such a tight fit.  But I know I'm in the home stretch and that the effort will be worth it.  I'm still hoping for a December 2006 first flight.

BTW: Mounting the solenoid valve right to the gascolator works awesome.  I'll probably open up the mount holes in the gascolator to the next larger size (there is plenty of aluminum there to spare) since I'm attaching the fuel flow and solenoid valve direct to the gascolator body.

Just what I needed: practical advice and a new perspective on things.


Here is the current plan:
1. Rigid aluminum line from the selector valve to the in-line fuel filter.  Adel clamp the body of the filter to the fuselage or firewall forward of the firewall.  
2. From the removable cap of the fuel filter to the fuel pump, run flex line.  Mount the fuel pump also foreward of the firewall.
3. The gascolator I have mounts right to the firewall, with the inlet facing the firewall.  It has 3 output ports: 2 are 3/8, 1 is 1/4.  

Plumb the outlets as follows:
a. rigid mount the fuel flow meter to a 3/8 steel fitting, and then flex line to the mechanical fuel pump.
b. mount the fuel pressure sensor to the other 3/8 fittting, using a steel adapter.
c. rigid mount the solenoid primer valve to the 1/4" fitting with a steel fitting, and from there direct to the primer harness.

A comment I've gotten about this setup is that I have more fittings in the crew compartment than absolutely necessary.   I'd use only the best quality fittings and hoses, and inspect this area regularly.

Another issue would be changing the fuel filter element.  I'll need to think about how to catch or drain out any fuel that would be remaining in the line and filter when I unscrewed the filter cap.

I'm sorry if my headline for this topic was offensive.  Perhaps I should have stated it a different way.  I was just frustrated because I really appreciate this site and all the porn and pharmacy posting seemed to be destroying it.

I can hardly believe how much better things have gotten.

Thanks for the aggressive actions you have taken.
