Q v4.0 - ArduCopter First/Second Flight and Crash
Well we are part way through out project on an autonomous quadrotor platform.
The first two videos are of the first flights. The third is the first crash (*sigh*).
Flight 1:
I am piloting this one and making sure it works before trying anything too extreme.
Flight 2:
Bryan is flying this one and he is testing out the performance of the ArduCopter
Crash 1:
I was piloting this one, and something just failed, cause is still unknown.
We managed to have a nice sunny day to fly the quads in the Brisbane Botanical Gardens.
The next step is to have it taking off and landing autonomously using the gps and pressure sensors. After that, get wifi-data.
We shall keep you posted!!

Looks like low voltage caused one of your ESCs to cut out. From the sound of it your flying NG? When you pulled the throttle low the motors were still trying to run?

+ get rid of the bullet connectors between ESC and motors

why are the bullet connector bad?

Might it be related to the problem you had in the first video, where not all motors started at the same time?

The bullets from the AC kit are out of tolerance. I've seen copters flip because of it.

All kits have now bullets removed as default. If users want to use those, they can solder them. Maybe on future ESCs we can have terminal blocks or something else that allows easy but secure connections.

I have the old kit, and I had the bullet connector. Since I have not soldered it yet, you suggests it's better to solder the ESC directly to the distribution board?

ESC directly to the motors.
I haven't had any problems with the deans connectors.

Oh, ok. So how do you detach motors from ESC if needed?

Simone, if the connectors are tight there are no problems but if they are loose connectors you might have problems in somepoint. We have also many quads that have thlse bullets still on and they fly without any problems. Also if we look the overall statistics, it is not so big amount that have been having problems.
If you plan to rebuild your ArduCopter, on same time you can remove those bullets. As said kits still have them but not as presoldered so its up to the user to use them or not.
Changing is naturally a bit more harder with soldered wires
