Evaluating Hobbywing's Reverse Brake Esc

The purpose of the ESC is to have a prop plane land and reverse the direction of the prop to brake and shorten the stopping distance of the plane. My interest is to possibly use this for my transport and shuttle.

Looks like any other ESC, except there are 2 extra sets of wires. One set is to program the esc, and the other to hook say into the gear channel.
To program the Esc, there are ten items with anywhere from 2 to 9 selections. Didn't want to program by beeps(UGH), so bought programming card.

The second wire set plugs into the gear switch and is the place where you reverse the direction of the motor(flip the switch).

Design: To save your equipment, they put a safety factor into it which doesn't help.
Procedure: To reverse the prop, you land, throttle should go to zero, flip gear switch (all it does is it goes from -100 to +100) , about 3/4 sec of nothing, then prop goes other direction even if the throttle is moved up even to 100% throttle.

So, why not flip the gear switch when throttle is little/lot/none from the off. First of all in the reversing process, you can't program to apply the brake. So whatever the prop is turning, it will not go into reverse(how about full throttle until after the programmed time delay is reached).
You know what would happened if the plane is flying, so they give you a chance to save it. So that's why no brake?

So, flew my plane and experimented. Most of the time, landed, quickly flipped the switch, moved the throttle about 1/3 (what would be your re-action time?and add 3/4 sec) and it was either stopped or almost stopped. Okay??????

Let"s try it anyway. (Right now, the only thing it is good for is to back up your plane to turn it around or back it in your pit area or if your overweight plane that comes in high,hot and heavy.)

So tried the following. Throttle off, then went up by units of 5-(prop is now turning), then flipped the gear-prop goes from turning to motor making noise as it goes to zero and then into reverse. The higher the throttle setting,(the 3/4 sec is removed) the tougher it is on the motor. How much damage and it's lifespan is in question.

Will do videos to show what happens when you have instant directional change.

Turning a lemon into lemonade? Got to thinking anyway to by-pass the system? Got an approach of automating so you reaction time and 3/4 sec is removed from the equation. Learning how to sequence(Dx-9) and knowing that the throttle can be used as an analog switch, and a mix so it changes the -100 to +100 might get it to done by the transmitter. Will let you know.

Any suggestions or questions?
