Tips on flying for a noob/ my first fly experience

[aforcefulthrust]

Hello guys

So i have experience with multirotors and flying them, just not the crazyflie. Got my crazyflie built and tried the first test flight today, ended up crashing about 5 times and decided to take a break before i break my crazyflie lol. I find that the crazyflie just shoots up too high in the air, and when i try to correct this it just falls to the ground. Having a hard time making it just hover. Any tips on this? I'm using the PC Client and an xbox 360 controller.

I tried switching my controls over to mode 2 style controls, throttle on the left stick and pitch/roll on the right but the option to save was never available...

Any tips from the experts is greatly appreciated.

As with most 'copters you will find that it takes more motor speed to recover from descent over a certain rate (you will hear the noise on the rotors change slightly as the airflow gets disrupted) than it takes to get equivalent lift at equilibrium or during lift. This translates into:if the crazyflie is in a hover and begins falling over the threshold point for the fans a small increase in throttle will leave the flie falling, having to push the throttle up high to recover from falling but then decreasing back to hold altitude. Yet, if you had given just a little throttle before this threshold it would easily rise.

If you dont have alot of experience or, if your rc experience was really mostly about 15 years ago keep the blue light towards you and put the mode on x the leaves two fans pointed at you and a blue light in the center. This way the default maps make forward away from you.



When flying indoors be aware of proximity effect from both the floor (gives extra lift) walls, and ceiling (will suck you towards them) you will find the effect most prominent around 2-6 inches from an object.



But as a feature request could have a stick/accelerometer map to a throttle curve to make up for the differences in acceleration when falling compared to hovering?

Also comparing barometer/accelerometer data I think could provide simple object detection based on the effect.

Thanks for the response. I made throttle more easy to handle by setting max throttle to 70%, and min to 50%. This lets the crazyflie rise and fall slowly while i get use to flying it. My problem now is I am use to flying in mode 2, and there is no xbox mode 2 preset. When I'm in the crazyflie client it lets me map the controller, but the option to save the device mapping is always greyed out, even after I map the controls.

When mapping the controller can you try starting with the xbox mode 2 mapping and remap that. When the save button is grayed out it means that all critical mappings (yaw, pitch, roll and thrust) are not done (or a bug).

No matter what I try, I cannot get it to save a new control mapping. Even tried renaming the .json input file to a .doc, and editing it in word, then back to .json - didn't work. Re-installed the client, doesn't work. Any ideas?

Got it figured out... I was using an older client version found on the wiki. Now I'm able to save my control mappings and finally fly without crash
