[SOLVED] How to glue shock absorbers and al.

Hi * In a former post, I indicated that I used epoxy glue to install shock absorbers on a Crazyflie. But it is not perfect and fixation failed after a time. P_20180221_111634_r.jpg Lucky that I found another method. I now use a contact glue. Begin the process by scraping the external face of the mot...

[SOLVED] To lower roll and pitch trim increments

Hi, I am really concerned to obtain a perfect stationary flight for Crazyflie. So I intensively use trim adjust command. But 1 degree as increment is too large. I prefer 0.2. In that case I obtained quasi-stable stationary flight with null command on roll and pitch axis (obtained through new deadban...

Buy Crazyflie and components in Europe?

Hi *
Really costly and complicated to buy Crazyflies and/or their components in Hong-Kong.
I know Elektrokit, neighbour of bitcraze office, but they are really short and many components are not available.
To buy in Europe should be fine...

[SOLVED] Roll-pitch deadband

Hi
A dead band for roll an pitch joystick command is highly recommended for stationary flight and progressive take off. This the issue #245 of bitcraze's Python client for Crazyflie. A solution is proposed. Rather easy to implement.

The answer is here:

I will delve into the question.... and open a new post if I find a solution.
Perhaps an issue should be emitted?

Re: Client freeze

And, this morning, I installed the flow deck... At first run, the freeze of the crazyflie occured... Estimator 2 is used. Sure it is responsible for this behaviour. Do I have to write an issue for this which looks like a bug?

Re: Client freeze

Hi! For two weeks, I fly crazyflie without vertical assistance: flowdeck or z-ranger. I neither had the freeze problem nor roll rate instability. I verified that estimator is the estimator 1 on connection console message. So the problem would be linked to estimator 2? I will make new test adding the...

[SOLVED] Ublox GNSS fix

Hi, I had much difficulty when trying to get a fix with my Ublox MAX M8 GNSS. The problem was only a bad soldering of the ground. Now, I get a fix in 1 minute when lucky and at most 2 minutes... The receiver installed on a crazyflie: P_20180107_191137_r.jpg and a new GNSS tab in the client. P_201712...
