RV-9A's wing with Rotax 914? by
Shin Gou
Looking at RV-9A's specification (weight, engine, etc.), I think a
Rotax 914 can power it very well, may give a better performance than
O-235. However, the problem is Rotax is far to light to be installed
on RV-9A.
So I just can't help thinking, well, why not a new design around
RV-9A's wing and...

Pilot Error? Is it Mr. Damron? by
Badwater Bill
C.D. Damron writes:
For example, if I build a plane that is impossible to fly or a
helicopter that cannot be auto-rotated, it is still very possible that
an accident report could conclude that I was at fault for not avoiding
a stall or not successfully performing an auto-rotation. Why?
Because...

Stick and Rudder's 'Safety plane' by
Barnyard BOb --
Ernest Christley misfired the following:
I'm about halfway through this book. It is quite an eye opener. The
author's explanations seem so insightful, cogent and complete. However,
there's this one blemish. Printed in 1944, the author makes the claim
that the rudder will disappear in just a...

Transponders, Radios and other avionics procurement questions by
Corky Scott
I'm at the point where I need to start collecting instruments so I can
build the instrument panel.
As always, I'm a bit shocked at the prices new or reconditioned
instruments cost: The typical panel mount radio goes for around $900
to $1300 depending on how much power and features you want. ...

A Simple Auto Engine Conversion by

I was thumbing through a catalog from Speedway Motors. They advertise
a magneto-type distributor. Assuming you didn't come across a
thrashed race engine with magnetos, couldn't someone put together an
engine worthy of aircraft use, by simply 1) ordering an aftermarket
engine with fuel injection,...

Replace fabric with glass by
Ernest Christley
Most of the fabric covered aiplanes I've seen didn't seem that hard.
That is, you could walk up to them and push the fabric in with your
hand. The way I understand the fabric process, it is basically a
composite structure. You have a nylon cloth with a paint "epoxy".
Could a much stronger and...

AN ENGINE FOR HOMEBUILDERS by

As of 2009 Amateur aircraft builders are largely limited to various
Volkswagen conversions. While such conversions may be as large as
140cid (2332cc) when using a Type I crankcase -- and up to 170cid
(2884cc) if you begin with the heavier Type IV -- the SUSTAINABLE
output of these engines is...

larger. I don't mind fussing...
