"Hi Ron, welcome to wonderful world of building your own multirotors! So, lets get a little more info first such as ESC, receiver. Are you saying the APM is only functioning when plugged into computer an not when connected to a battery? Are you using…"

""On last post you said i just need to use either power moudule or esc with bec does it mean that i dont need to use power module and can power up my apm only using esc"

This is correct, if you are going to be using on screen display then use the…"

"With the gimbal control, you will have to 1. figure out which channel (s) you want to use on your radio, preferably sliders or knobs, and connect them to the appropriate input channel on apm. Output can be whichever output you choose. Once you have…"

"Hi Nischal. Welcome to the forums.
1, I believe you can manually control your gimbal through this and any apm based flight control, but it won't do it automatically.
2. I wouldn't risk it. Currently my flight control is powered by bec only. I would…"

"Hi Bill, nice designs. I like the sky surfer design you have (black one looks like a surfboard). Might have to buy a set of plans from you. What are you using for the plates?"

"It is a sad day. Sorry for your loss."

"Oh, one other thing, if your motors are rated at 400g thrust, that is typically at full throttle when looking at the charts. A good hover range is around 50% throttle which would put you in the 200g range thrust range per motor. "

"These http://www.hobbyking.com/hobbyking/store/__8932__Turnigy_2200mAh_3S... have been working well for me, a little under rated for my set up but the do not get warm like the higher rated Zippys I've been using that arent that great."

"That battery will most likely be too heavy. I get about 15min flight time on my 450 quad, but it is super sluggish just due to the weight, but only use it when the camera is on it. May also not fit the frame as the specs state a much smaller…"

"Well, do admit to my noob mistakes? I had the motors connected as if it were CC3D which is what I am familiar with..... these are in a different order. I had them spinning the right way though, thats gotta be worth something. I was wondering why it…"

"smaller and still carry the $200 price tag...."

"Agreed. pixhawk is just way too big for most applications. 

Any ideas on why I am getting no throttle response? I arm, increase throttle and goes straight to aproximately 60-70% and no change until I lower throttle and it will just drop to around…"

"Thanks Edgar. Did you recently post those? I couldn't find anything online when I was wiring it up..."

"So, it seems as thought this board has some power issues. Mine won't power anything but gps & compass. Pawel, try moving accessories to a separate power source and let the board have its own power, as it may not want to share.

On another note, I'm…"

"That's what I did first but none of that helped. I went to the parameter settings and found where stick input channels can be assigned. I'm still learning the apm setups, a bit different than cc3d."

"I've seen a lot of people that will use rubber bands, velcro, zip ties, install some spacers, or I've seen a custom 3d printed holder as well."
