Stang said it well...

I helped a fellow club member with his brand new O.S. 91 equipped Seagull Cub.

I helped him go over it and maidened it and trimmed it out for him.

After landing he made some adjustments and he asked me to get the plane back up in the air again as he was nervous... ( he's a decent enough flyer ).

I did one lap of the airfield with this plane at 1/4 throttle ( it has GOBS of power with a .91 engine. ).

All of a sudden I lost complete control. However the airplane kept flying slow stable circles.

Unfortunately a stiff breeze was blowing that day, so the plane would climb on every circuit and move further out.

After 12 minutes we could no longer see the plane even with binoculars... it was up in the clouds. 1-2 minutes later we could not hear the plane at all.

My friend went home upset.

About 45 minutes later a truck pulled up with three people dressed in business suits and with something bright and yellow in the bed of the truck.

At first I though they were attorneys looking for someone to sue.

It turned out that they had seen the plane make a graceful landing on the side of a major interstate highway 14 miles away. They told me that it landed so gently they assumed that someone nearby was controlling it.

They knew about our airfield, so they brought it over looking for the owner.

I called my friend and told him that his "miracle plane" had been found.

There was not the slightest scratch or bit of damage to it. It was just completely out of fuel.

He found he had not put the retention clip back on for the RX so it had lost power completely.

This is one stable plane when it is properly trimmed out!
