It must be something in the air.. (or not wanting to be in the air).
I just finished my two builds, (no flights yet) and decided to put power to my “Honey Badger” with the KK2.1 in it. It started doing the “Fish out of water” deal. While messing with it a little trying to figure out which way it was flipping (it flipped different directions every time) it snapped a complete arm right off.
Observations:
I’m sure it’s one of the 1.2 million different settings between the FC and the TX, but when I would idle up, it would go, creep up (as I’m creeping it up) and get to the point where it was getting close to lifting off and then go APE S#IT and give me an introduction to aerobatics. NOT COOL KK! It was close to 60ish % (I was using a 5000mah battery when I should have been using a 2000mah, just didn’t have the connectors yet).
I called it a night at that point and turned off the lights, took a shower and went to bed. This morning I did a damage assessment and replaced the arm. (Came with a spare one and I ordered x2 more with the kit). One thing to note, the quad is NO WHERE NEAR as robust as I initially was lead to believe. Its 70ish deg in the building where I was trying to get it up and so it’s not because it was cold outside that it snapped so easily.
Other observations:
I thoroughly checked the rotation of the motors. No less than 3 times. (x-Quad) and even verified the information on the internet (because THAT is always correct). But, the short of it is, the trailing edge of #3 (one that broke) has a chip in the trailing edge of the prop, just one end. Like it bent back. Obviously wouldn’t think it would do that if rotating properly. BUT… I KNOW I checked it.
Well, I’m putting that one aside for right now, especially since I don’t have the correct battery strapped to it, and focusing on my F550 again. It’s basically ready, EXCEPT for a quick controller question I’m about to ask on the Group Build forum (controller config, finding conflicting information about (from top to bottom in the mixer (using a Turnigy 9XR, I’m sure it’s the same on all of them) is it:
Throttle
Aileron
Elevator
Rudder
~or~
Aileron
Elevator
Throttle
Rudder
I’ve seen both (in YouTube videos) where they say “It works for me…”
Thanks!
