You rang? Yes this is possible. The APM I believe has a slot to connect a GPS to. Being Arduino based, the APM can be custom programmed with whatever fun GPS flight path you like. It also comes with the hardware like a gyro/acc and pins needed to connect your ESCs and other tech. Happy coding.

Yes if you go the route of buying you own hobby rx/tx it should have a failsafe and you wouldn't need the one coded in the Arduino.

So the current code that I am using is for an Arduino based transmitter and receiver and then the receiver being connected to the kk board. The "map" functions at the joystick array is where you adjust the limits of your pots on your controller. If you have your own hobby rx/tx then you only...

Very true, I was only thinking about flying it indoors.

With having the Arduino intercept the rx data you can then edit it with you sensor detection and what not before you send the final output to the kk board. I plan to mound 4 ultrasonic sensors to my quad to detect close objects and avoid them.

So unless you have a team of highly trained coder monkeys under your bed, save yourself months of trouble ( by personal experience ) and get an Arduino along with a kk board.

Definitely will be a to easier to rebuild after the crashes! just don't step on it D:

As for the Arduino code, you'll find there aren't many good tutorials. But what you do have is the access to the source code to other people's Arduino quadcopters. There is Arducopter, Bluecopter and of course Multiwii that you can look at. There is also source code for computing the gyro/acc...

You would think so. But I guess they are pretty close clones to they sell for about the same price. It's a good mid-range charger, I guess you get what you paid for instead of one of the like $80 ones.

I use the iMax B6. But the first one I bought just stopped working a week ago and I had to buy another one. They often make fake ones and sell them which I guess don't work AS GOOD so you run the risk of that if you try to buy one. You will have to buy a AC Adapter as this does not come with one.

Yeah my iMax B6 also had that problem. I took it apart but nothing seemed wrong. You gamble with buying a clone instead of the real thing when you buy one of those chargers online so I just chalked it up as a faulty charger and bought a new one of the same model. This charger seems to work fine...

A good way to start coding you quadcopter/droid/terminator/skynet would probably be with an Arduino. It's a microcontroller that you can buy in many shapes and sizes. It is coded in c# and you can use the free Arduino IDE to upload you "sketches" to the board. A multirotor friendly version of...

Answering your question about the charger price, it costs $22.31 USD not the price you had in the screenshot. Sorry for your confusion :)

As George said, the 4 channels would be controlled with PWM. If you mean a multiwii FC by connecting a Pi and an Arduino together then it shouldn't be too hard. However, you want to stay clear of sending input through the serial monitor where this ( in my experimenting ) has slowed down the...

The software side will be mainly taking the output you get from the on-board gyro/acc and converting it through PID controllers (for Pitch Roll and maybe Yaw) into throttle adjustments for the motors to keep it stable. The Arduino has a library for PID controllers and you may have already used...

I watched your video and it seemed to me like you were testing your quad with the props on and nothing to keep the quad strapped to the ground... Very bad things can happen... Anyways, I'm happy to help in any way.

With it being an X, it needs all 4 motors to control pitch and roll. Placing it like a plus would give you only half of the correctional thrust you need if that makes sense.

Right, this is the idea. Seems simple enough right? I hope it'll work out when I test Saturday.

I just feel it will be more efficient to suspend it like in that video.

I wouldn't suggest a table like what I have been doing. I suspect that the quad is getting major prop wash from touching the ground all the time ( idk though I've never actually flown a quadcopter before). I'm going to make a rig that suspends the quad into air to test one axis at a time.
