G+_Andrew Schwenk Posted May 18, 2015 Share Posted May 18, 2015 Multicopter question. Hi, I'm building a 250 quad and I'm having some troubles getting the receiver to work. I basically followed the Alienx build and ordered all my parts seperately. The only things I switched out are the motors, I'm using RTFQuad's HL2208-15 KV:1100. Esc's, and flight controller are the same. For a transmitter/receiver I'm using the Airtronics Aquila-6 channel 2.4 GHz. The batteries, if it matters are Thunder Power RC 2100mAh 3-Cell/3S 11.1V G8 Pro Lite Plus 25C LiPo Battery, and HOBBICO LiFeSource LiFe 6.6V 1100mAh 10C Rx U Connector HCAM6416. I'm using the LiPo to power the motors/esc/flight controller/lights, and the LiFe for the receiver only. Although when I turn the receiver switch on it seems to turn some of the lights on as well as the flight controller. I also have a Spektrum Voltage Protector somewhere in there. Here's the problem, when I turn everything on I get a beep and all the lights come on, but when I go to the receiver test screen it has no signal. I've checked and double checked my connections and I can't find a problem. Could it be a hardware issue? Please help, I'm a first time builder and I'm in $600 with no way out.

G+_610GARAGE Posted May 18, 2015 Share Posted May 18, 2015 Try rebinding the receiver and transmitter, maybe something went askew and they lost binding. Link to comment Share on other sites More sharing options...
G+_Andrew Schwenk Posted May 18, 2015 Author Share Posted May 18, 2015 I rebinded the remote, but the flight controller still says no signal. Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted May 18, 2015 Share Posted May 18, 2015 First get rid your second battery and see if it works. If it doesn't (leave the secondary battery disconnected while troubleshooting), connect an esc directly to your receiver to determine whether it works or not. If the motor doesn't spin up, then something is wrong with your remote. If it does, try running a dedicated wire for each output of the transmitter to your flight controller. Just curious, why do you have a transmitter only battery? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted May 18, 2015 Share Posted May 18, 2015 What mode are you using? The PWM or a CCPM (sp?)? Try 610bob's idea with the esc. I wonder about the dual battery also. Tie the grounds from the 2 batteries together. Link to comment Share on other sites More sharing options...
G+_Michael Heinz Posted May 18, 2015 Share Posted May 18, 2015 I second 610bob 's idea - I basically use the same technique after any bad crash - I hook up the ESCs one at a time to my receiver and throttle them up to verify the ESC and the motor are okay. (I use channels 5&6 on my FlySky for this) Link to comment Share on other sites More sharing options...
G+_Andrew Schwenk Posted May 18, 2015 Author Share Posted May 18, 2015 Hey everyone. thank you for the suggestions. I tested all the escs directly from the receiver and they work. The reason behind the two batteries is Airtronics says not to use anything over 4.8.~6.6v and my LiPo is an 11.1v. But it seems when I plug them both into the quad the KK is drawing power from both sources through the receiver. When powered on I can get number inputs to read from the KK when moving the remote sticks. But it still says no signal in some of them, could something be when going through the flight controller? Also the quad constantly beeps when turned on, is that good/bad/ no concern? Thanks all Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted May 18, 2015 Share Posted May 18, 2015 You don't need the second battery. The esc convert the battery voltage to 5V for the flight controller and receiver. If you connect the transmitter to the flight controller and an esc to the first motor output of the flight controller, then the esc and the battery is going to be fighting each other for power. I would highly recommend removing the second battery and see if that works. When you have two pieces of electronics communicating to each other on separate power sources, things can get wonky pretty fast. I get beeping from my quad when the esc aren't getting a signal from the flight controller. If you are messing around in the menu of the kk, this would be normal.

G+_Andrew Schwenk Posted May 21, 2015 Author Share Posted May 21, 2015 610bob Hey man, I did what you said to, and I took the battery off. The receiver works great with the flight controller now, but my aileron and elevator are swapped. I have an Airtronics Aquila-6, and I can't find anything on this remote anywhere on the internet. I've tried reversing the channels but all that does is change the directions, up is still right or left and down is still left or right. I'm really at a loss right now, problem after problem after problem. I can't figure any of this out. I'd really appreciate if you or anyone else has any info on how to fix this. My remote can be HELI or AERO, and it has a couple different modes like CP3F OR CP3BS Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted May 21, 2015 Share Posted May 21, 2015 Swap the aileron and elevator wires going to your receiver. I don't believe there is a standard output order for receivers, so if you attached 1 to 1, 2 to 2..... aileron, elevator, throttle may not line up. Also, don't get too worried about hitting problems. Thats how we learn. I have smashed my head against problems for months until I solve the issue. But I always come out of it with a little more knowledge.

G+_Andrew Schwenk Posted May 21, 2015 Author Share Posted May 21, 2015 Many thanks for your help, Josh (right?). I appreciate you being a know-it-all Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted May 22, 2015 Share Posted May 22, 2015 Yup, Josh. I'm glad I could help. I hope that this is a start to many more projects (multi rotor or otherwise). Link to comment Share on other sites More sharing options...
