This is from memory, I think the aileron movement is 11.5 degrees up and 11.5 degrees
down.

I have completed most of the fuselage now and am at the point where I need to start
running some wires, i.e. elevator trim, tail light, flap motor. I can see
that there are many avenues from the elevator trim tab to the front. I have a
center stick and plan to put the trims on it unless there is some better reason
to put them on the panel. I would appreciate suggestions on type of clips,
grommets, tabs, splices at the motor end, etc. as there seem to be several possibilities
from the hardware store to Wicks. I especially would like a good route
from tail to stick. I don't know which side might be best to run down a longeron
or when to go through or around a bulkhead or if I need to go past the
stick and then back again on the floor or even when /where it will drop to floor.
I can figure a route for the wing wires but need some possibilities for the
tail and flap motor. Thanks again for ideas/products. John

B+C Specialty has generic schematics available free at their site, and many
of the necessary components you'll need. Shouldn't take much to modify to
fit your situation, and they're good people.

Hi John,
I've got an electrical page on my site, www.macsmachine.com, that might
help you with the methodology of running wires throughout the plane.
Some electrical diagrams
that may be helpful too. Pictures clicked go large for a better view and
perhaps there and other pages will help you with specific routing etc.
See link, http://www.macsmachine.com/html/electrical.htm
Best regards,

| Subject: | Bad takeoff, but still good landing |
Last sunday was a beautiful day here in my region and I couldn't resist flying
after completing the engine portion of my annual inspection. I changed the oil,
tested the compression (150 +-5 on all cylinders), timing OK, removed valve
covers... all neat, cleaned air filter, etc, etc... all was GREAT :-)
Well, I did my preflight inspection, did my runnup (at about 3600 rpm) near runway
15 of Beloeil airport, positioned myself on the runway and applied full throttle.
The feeling of accelerating and taking off on such a beautiful day was
enjoyable... for about 4 seconds... I climbed to about 5 feet in the air and
then, total loss of power (like lack of fuel). I was getting close to mid-runway
(maybe even past it... don't remember), and I pulled the throttle, and
landed the plane. The engine was still running at low rpm.
Then I went to an area to check the engine behavior... when I raised the throttle
above 4000 rpm, it would do the same thing. I then tried at lower rpms...
would just take more time and at about 2100 rpm, the engine would run smooth,
miss and run smooth again.
My first idea was the fuel supply... so I disconnected the fuel line and filter
from the carburetor and tested the fuel flow.. very good.. certainly, the issue
is not that. I then removed the top of the carburetor (Holley 5200) to see
if the bowl has fuel and to see if the float valve operates properly... bowl
was OK (but with some small debrits on the bottom) and floats appeared to work
OK (I applied fuel pressure while playing with float movement and making a mess
besides the catch can I was using).
My questions: what failures could create this condition?
1. fuel system ? (I think so)
2. ignition system ?
3. cam shaft ?
4. ?
Oh... a funny thing... I'm surprised to notice I did not get excited through this...
I don't think my heart beat got any faster during that failure.
I got a strange feeling that I'll miss many good days of flying opportunities now.

Michel,
I'd look for a fuel restriction in the line, gascolator, filter or
anywhere ahead of the carb. This doesn't sound like an ignition, choke
or spark type failure.
A fuel restriction would allow you to get full throttle until the engine
need gets ahead of the flow. Then it would starve itself at full setting
after running full out
for a short time.

Indeed that was my first impression. The symptom is exactly it. I did check the
fuel flow right at the carb (disconnected the filter from the carb, put the
hose towards a container and activated each fuel pump) and all was nice. I did
check the float action and flow control of the float mechanism (as much as
I could do it). I suspect a carburetor defect, but I'm wondering it this could
be anything else.
At the parking lot, I tested the operation with my three fuel pumps and my two
ignition.. none would change anything in that bad engine behavior.

Did you check that your tank vents were not plugged up? Mud dauber wasps have
been known plug them up.

Heat source near a fuel line causing vapor lock (possibly a dislodged heat shield)?
Air leak in the intake manifold?
Hope you find the solution. Let us know what it is when you find it...

You would get similar symptoms if the air filter was clogged up or the exhaust
system was partially blocked.
Do you have a fuel pressure gauge installed? A fuel pressure pickup just before
the carburetor would give a valuable indication of fuel system performance.
