My first maiden flight didn’t get off the ground. The left side wanted to move up first. My roll is set at P gain 26 and I gain is 14. What do I need to do to correct. Is it the P or the I settings? Not sure what they mean either. (Percentages) Do you ever change the limits? Almost there but wanted somebody’s advice on the situation. Thanks3 March, 2015 at 05:50 #11367tomteblossParticipant
Have you calibrated the ESC to spin up at the same time and mounted the propellers the correct way?3 March, 2015 at 14:36 #11398
Sorry but the maiden flight is a Tricopter. All the motors come on at the same time but when I start giving more throttle to see it move the M1 motor wants to move up first. Do I need to go into mixer editor and change just that motor. All motors are set to the same percentage. Throttle 100, Alerron 87, Elevator 50. You wouldn’t think that I would change these settings. Haven’t figured it out yet, hope I don’t have a bad board.3 March, 2015 at 16:45 #11399tomteblossParticipant
I had the same problem. But the tail raised for me on my maiden flight. I quickly realised that I had shifted the prop on front left and front right with each other. So the two in front sucked the copter to the ground instead of lifting it.
Settings in mixer editor for me right now is:
Channel 1/M1 in mixer editor: Throttle 100, Aileron -87, Elevator 50.
Channel 2/M2 in mixer editor: Throttle 100, Aileron 87, Elevator 50.
Channel 3/M3 in mixer editor: Throttle 100, Aileron 0, Elevator 100.

Try posting your set up so people know what you are using. Try checking the Receiver Tab or Receiver Test to ‘zero’ or balance your input channels with subtrim on the radio. Try calibrating your ESC’s. Try enabling Self Level and using that to take off, and/or using your inputs to offset the unlevel taking off.
It sounds like you are using KK2.1. Depending on which firmware you have installed, make sure you are actually calibrating your ESC’s: find ESC calibration on the board menu and select, unplug battery to depower the board, turn transmitter on and move to full throttle, hold KK2 button 1 and 4, while holding buttons plug battery back in and move throttle stick to zero, listen for ESC calibration sound.
Be careful about doing these things with your propellors on, but another thing you can also do with your propellors on is arm copter, spin motors up just a little and check left/right, forward/back to make the copter hop or pick up a little on the corresponding side, i.e. move forward, back picks up, move right left picks up, etc.4 March, 2015 at 04:39 #11434
I was on uneven ground.I figured it would compensate for the difference. I did do a esc calibration and ended with a beep,beep- beep. All try a few more things. I really appreciate all the help guys, I just want to see this baby fly.7 March, 2015 at 05:33 #11579
Still having problems with my tricopter. When I spin up the motors I can get the left motor to hop but the right motor doesn’t seem to wind up enough. Another thing is the right stick only seems to work forward and right, nothing happens down or left. Not sure what or how to correct this problem. All of the props are installed right. I only changed the rotation of the motor to spin the same way as m2 and props are the same on m2 and m3 CCW. I’ve gotten a lot of good advice and found the hopping from previous text.8 March, 2015 at 13:01 #11615AlanParticipant

My setup is the following: Sunnysky 2216 800kv, 11 props, 20 amp Afro Slims, EzUHF 4ch, a bluebird servo and a Naze32. However, I can’t seem to make my Turnigy 9xr work with the Naze. The roll and pitch channel move together when I move the aileron. Anyone have a recommendation?
Thanks a lot,

I’m curious.. I do not see anyone using DJI’s motors (E300 or E310) Any reasons why it would not work nicely ?
I was thinking the screw-on propellers are really nice and convenient.
Also a Hex set would make 2 tricopters at a relatively good price18 March, 2015 at 10:18 #12149mmemeteaParticipant

Would you be kind enough to share your PID settings. I have the same motors and the weight is roughly the same.
