Newbie does more dumb stuff- the saga continues.

So I have my second new quad that I took apart and painted yellow and blue. I have the Quantum diversity VRX , FPV camera and VTX kit from Hobby King on it along with another RD9 Rx (My newbie version of a mod/upgrade.) Well I put it back together, sure I had the correct motor orientation set out on my bench. It went together good and I did all the little mods as well as the RD9 bind which is really easy by the way... :) Anyway I went into Libra pilot and went through the firmware download and set motor speed, transmitter wizard etc... put on the props. Everything went good and it should be ready to test fly.

One would think that but I had a problem getting off the ground. The ass end of this thing wouldn't move, more throttle and it just flipped over. I think: hey, no problem I've seen this before, I must have the props wrong (idiot)... I switch the props quick, not really looking to see if they are actually the correct orientation (still have to think about it and its not just obvious yet ) and hit it again. The quad jumps up in the air and does a high speed yaw turn. WTH? I crank up the trims to try and get some yaw out of it... nothing. Ive been gaining experience so I would think that I was moving beyond stupid mistakes. I look at the props... then look at the props again. The two rear props are wrong, but it actually flies (really bad) and gets off the ground... WTH? So I take it back inside and I'm looking at... finally a light bulb goes on! I have the rear motors wrong!

Crap! Its getting near dark outside and I want to see how my new fpv camera works. So I quick de-solder the ESCs and motors on the rear without taking off the arms. Its really tight in there! Switch them around and solder them back up. Go to Libre pilot (I don't know... maybe I need to reconfigure again? Cant hurt. ) So I get to the motor rpm calibration, plug in the battery. Poof! white smoke! Unplug! Unplug! Dang it! Looking in where the ESC wires solder to the board I got slag touching. So I get in there and clean it up. Power it back up. No CC3D music, green light on, blue light flashing slow with usb hooked up. SO I think I fried my controller or my board and maybe an ESC. With a volt meter I have about three volts to all the motors, mega ohms across all 3 wires on 3 motors and 2k ohms on the sig wire to ground on the ESC/motor that that I shorted out.

I'm not sure what all I fried so Banggood got more of my business with a new bottom board, CC3D controller and an ESC.

I'm learning, but learning the hard way. Thanks for reading! :)

Thanks for the prop tip.
Yes rushing is not good and can usually turn out bad. I know this and knew it while doing it, but my impatience to get this thing up in the air and check out the new fpv system got the better of me. Getting time to put this quad together has been dragging out and I felt like a little kid with a present that he can't open. ;)

I'm learning...
