So, you've just attained your first truly air-worthy flights. You can now capture some cool FPV footage. Maybe you should take it out and do some laps around the field to get yourself comfortable with the speed and power of what you've built. You should probably do this on a day that is perfect, in case you have some kind of complete system failure. You know, no wind, no rain, dry ground... Maybe not in a swamp, I would say.
All of that sounds like wisdom to me.
Thank God I chose to ignore all of it!
After watching a few YouTube videos on doing rolls and flips, I decided it was time to give it a shot. I recalibrated the controller so that I could switch auto-level off and on via the flaps switch. The first flight is with auto-level on, so it's pretty stable.
The second flight, however, is with auto-level off, and you can see how it's much harder to fly, especially on take-off.
So, the basic gist for rolls and flips is that you get some altitude (everyone said at least 30 feet, which I had), give it 100% throttle, then pull back to 50% and throw the stick in the direction you want to roll or flip. Simple, right?
Oh, there are some settings you should probably set up in the KK2.1 flight controller... I thought I was good.
If you listen closely, you can see that I give it the throttle, jump up, then reduce the throttle and throw the stick right. Unfortunately, the quad went to about 135 degrees, then stalled. In the split second I had to think, I upped the throttle, thinking that might pull it around.
Instead, it just turned it into a rocket, straight into the ground...
Sadly, the field I was flying in that day was more of a swamp due to a few days of rain. The flight controller immediately shorted, but not before the props all dug divots in the ground.
As the first motor to impact dug in, the rest of the quad bounced over. This sheered off the drive shaft on that motor. This is, apparently, rather hard to do! I feel accomplished.
Oh, and all the props snapped.
Two new motors and a new flight board are on their way. I think I'm going to get comfortable in auto-level mode and then do some more experimentation with flips and rolls.
