I have a problem. My RV4 only fits in my hangar
if I insert it straight in oriented at 45 degrees.
Getting quart into a pint pot.

Otherwise the wing span is too long to go straight
in. Dollies under the wheels work but you must jack
up the airplane some how to get it on the dollies.

Then I discovered the wheel pants cover so much of
the wheel that the dollies will not stay under the
wheels when moving the plane around. It is real easy for
them to kick out from under the wheels. The pants also
make it near impossible to jack it up in the first place.

I finally came to the conclusions I need a CC engine
host to get the plane in and out quickly. Harbor
Fright have them for relatively no real money.
Just U.S. dollars :)

Since it must be precisely done I put channel
rails on the floor to guide the CC engine hoist.

Next problem was how to find a hard point
on top of the airplane for the CC engine hoist to grab
when the cowl is on.

It is too time consuming to take the top
of the cowl off every time I move the plane in or
out of the hanger.

What I came up with is a bolted on block of
aluminum to Tracy PSRU adapter plate that
extends up to just inside the top cowl skin.
Screwed into that block will be a forged tie
down ring from the Vans catalog. It screws in and out
through a small hole in the top cowl skin.  I'll keep it in
the airplane when not needed.

The picture shows just a 3/8" hole in the PSRU adapter
plate with a swivel fitting and clevis right at the moment.
No block yet.

An unintended advantage is it is real easy to rock
the wings up and down and throughly mix the two cycle oil
with the fuel :)
