I have been busy flying, so I have not been on the car. It has however allowed me to finish (almost)an electronic and computer programing project.

Yea, I still have some issues.

Was the last picture a takeoff or touch down? Looks like it's still in one piece at least.
That's about as far as it got. The first attempt I found the controls were way to sensitive. I spent the afternoon adding controls to the program to reduce the sensitivity of the throttle and bring it into the appropriate range of motion. The motors don't come up "even" for a number of reasons and I put controls in the program to adjust individual motors.
Problem right now is 2 fold. I can't sense the exact output so I am having a difficult time finding the spot in which all 4 are level.
Second problem is the gear is so narrow, when it begins to come up one side lfits, then it's too late. I am going to widen the gear before I try it again.
I originally started this project with reading the servo positions with a timing circuit and modifying them in a micro processor then sending out to each motor. Idealistically that would be better. Problem was the servo update times were to slow to control something of this nature.
My goals? I duno. I am playing.

Time for a gyro??

Yea, it's just not as easy as it sounds. The gyro inputs require mixing. I started out building a circuit which decoded rc-servo signals, added gyros, mixed it up and fed the appropriate signal to the appropriate motor. Problem was the servo update times were too slow to fly it.
So now I read the values from the joystick, do all the mixing then send the commands through radio modem. Any gyro results would need be sent back to the computer to get processed. I could actually do that but the radio modem either transmits or receives. It means it could not accept commands while sending which would cut my response time in half.
So I think the solution would be go back and look at other microprocessors which would updated the craft in a timely fashion.

Damn Gary isnt there anything you cant do??
