Brian Trubee


I was up in Seattle last week so I stopped in a Brian's hangar.
He has built a rotary powered RV4 very similar to the one I have.

Here are a couple of pics. His early trouble with Tracys EC2 were
traced to ignition crank angle sensor problems. One needs to monitor
these with a data acq system or O-scope to be sure they are working right.

Brian and I were discussing the use of a camera and display in the
cockpit to aid vision forward when taxiing and taking off. The center
line of the runway is completed blocked when in a 3 point attitude.

If mounted on the tail wheel spring it would give a view of the main
landing gear
relative to the height from the ground and in theory help during landings.
One of the things I miss about high wing airplanes.

I did a bit of research at Fry's and discovered lots of small camera options
due to security concerns. Unfortunately they all sent the video to a TV
set and few included a monitor of any kind let alone a small flat one.
Many were wireless which I considered marginal for aircraft use.

Fortunately the Fry's TV department had some suitable 7 inch solid state
flat
TV sets. Here are several.

You might also use it in the air to get weather from your local TV
station.

Let me know if you cannot see these png's.

Paul, here is a link to a potential backup  camera.

The 150 degree turns out to be a problem as the end of the runway
is a mere speck in the far distance. What one needs is something more
modest say 45 degrees or even 90 degrees. More on the cameras angles later.
