    The IMU calibrates every time you arm the drone so you need to make sure you arm it on a level surface to avoid flying off in one direction.

    The sturdy quad build is designed with re-enforcement pieces to avoid the rapid deconstruction: /pages/cool-designs (of course there's also super glue)

    You bring up a good point: we aught to add code to detect the motor inputs are not effecting the controls and disarm the drone.

    Apple should update the app store soon with the new 1.4.0 version which adds tilt-to-fly controls.

    Even making sure we arm it on a level surface, it still doesn't have a sensitive or quick enough self-righting ability to keep from flying off sideways.

    My initial experience has been much the same. Arm it on a flat surface, wait the prerequisite amount of time, power on and off to the side it goes!!!! I have not yet been able to get it to just hover on the spot.

    Edit- Just tried an idea. To mitigate ground effect issues I have armed it on a level surface and then held it elevated off the ground in one hand while increasing the throttle until it could carry it's own weight and then I removed my hand. This has been a huge improvement over earlier attempts to launch the copter directly from the ground. But still the controls are really touchy and so far I have had to power down the copter quickly as it starts to build up swinging oscillations which become uncontrollable. Like a seesaw effect.

    I tried that too with identical results. ( I even stuck a short pendulum / tower to the bottom at one point to serve the dual purpose of (1) giving it an elevated launchpad away from the ground effect and (2) creating a lower centroid & extended moment of inertia to make it more difficult for the thing to see-saw. While it did serve both of those purposes to some degree, and the unit didn't tip dramatically, it still instantly zipped off sideways.

    What seems to be happening here is that while there's decent enough attention paid to pitch and roll control, perhaps the hardware just isn't able to sense translative movements. In other words, the gyro is actively keeping the unit more or less upright, but it doesn't feel the craft drifting sideways. It's asking a lot for something at this low price point to have a state-of-the-art braking function like the DJI Phantom, but there has to be a way to keep the slippage from compounding upon itself like it does.

    p.s. The compounding drift occurs to equal degree with or without the pendulum/tower thingy I mentioned. That was just a one-off experiment. )

    I am just like John above. Firmware upgraded to 1.4. Swapped blades to ensure proper motors and blades in the correct corners. Spoke with Customer Support guy Robb. So far have not been able to get it off the ground without it dynamically destroying itself. Wires are getting wrapped around the blades. The struts for the motors will not stay attached to the flight board. I tried reinforcing the lego with additional pieces from the package of parts, yet I now have two broken blades.

    In the exact same boat here. I got this for my son to learn about electronics and we're at a loss here. we've built the 4 prop and the 8 prop, even updated to FW to no avail. it doesnt help that the props are labled A1/A2/A3 or B1/B2/B3 and the manual doesnt refer to them using this nomenclature.

    All in all, am i expecting too much here?

    If you have issues with the lego pieces falling apart try the sturdy build on the designs page: /pages/cool-designs You can of course use something superglue or Le Glue (releases in hot water) to hold models together.

    Make sure you are arming it on a flat surface so it sets the horizon correctly. We improve the control responsiveness in the 1.4.0 default configuration.

    This is me flying the sturdy quad build (no super glue) with 1.4.0 firmware:
