Two in one - Canalizer and Air-Brake.

Here is the story how it was born:

We all looking for constant speed, I realized that the down lines are the only thing that we still have difficulty to control, we start it in a certain speed and the speed always increase, that is simply physics.

For years we are trying to solve this problem variously: Motor brakes, wide props, wide fuselage, thick airflows, round leading edges, contra rotation, air brakes, etc.

But we still haven't found a significant solution for that problem.

For some times I was thinking, why not we use a big Air-Brake like the F-15 Eagle has? And I started to think how it can be done in the fuselage floor.

In the meantime I saw the new CPLR GALACTIK with the anhedral ventral T canalizer and thought, wow!!! That is a good idea.

One day when I was asleep the idea came to me in my dream. Why not put the anhedral ventral T canalizer on a shaft rotate it and turn it to an Air-Brake, I waked up and as you probably understand I couldn't sleep for a quite a few hours.

In that time my friend Amram Leshed was judging at the W.C. I told him about my idea and asked him to consult the idea with some of the pilots.

Most of the pilots that he consulted with thought that it is not a good idea, only CPLR said why not try it and he asked Amram to tell him what will be the results.

CPLR responses gave me the last push to go ahead and build it.

Amarm and I went to the test flight.

I was really tense because we didn't know how the plane will behave so I reduced the Air-Brake gradually.

The Air-Brake required quite a few elevator down mix but it didn't have any pitch nor rolling motion.

The plane dived straight down very slowly in a constant speed!!!

The big surprise was when I flew the P-13 sequence, the rolling segments became much straighter, and I just couldn't believe that this is my plane!!!

One think is still a mystery for me: the ailerons became more sensitive so I had to reduce the movement; anyone has any thought way it could happen?
