Pixhawk PX4 Flight Controller+Safety Switch+Buzzer+I2C Splitter+4GB SD Card

I have purchased several items from Readytosky and have had great results every time. I have found their support to be very responsive and willing to solve any problems I've had. Regarding the Pixhawk PX4, I originally had two problems - getting telemetry to work and successfully calibrating the compass. Both were resolved. The compass I was using was defective and was replaced by a new one (purchased from Readytosky) which works fine. The telemetry problem was my fault - used a similar looking module on my laptop - when I used the correct one, telemetry worked.I have not yet flown my Tarot Ironman as I am waiting on a receiver and I have to order a 6S lipo, but looking forward to it.

Never got it to work. The sd card won't stay in. It was in when I got it but it pops out now. I found it on the table when I was wondering why it wouldn't connect.This has stopped being fun.

Very cool board with a lot of different programming options but a pain in the rear end of program I am still unable to get mine off the ground when I go to disengage the button for the safety it will not allow me to go to flight mode still unable to get off the ground would recommend easier board

Awesome flight controller at an awesome price. Easy to mount up and setup. No errors. Solid build quality. I'm a big fan of all the redundancies and automatic fallback, you don't want your rig falling out of the sky because you got a second rate controller.

I found the Readytosky Pixhawk PX4 Flight Controller and associated parts to be very well made and overall of good quality.Using Ardupilot Mission Planner I upgraded the bootloader and flashed several images into this FC ( set as a fmuv3 board ) with no problem.On the bench it works as advertised.

I started with these flight control boards when I first started building drones and have to say they really aren't as reactive as most of the Beta Flight chips that require soldering yourself.If you don't know how to, or just don't want to solder this is a decent way to get your home made drone up in the sky.I have to say after learning both sets of software I like betaflight much more.Also, I got a yellow light on one unit with my computer saying Al's error or

Mission Planner will not detect board in either firmware or legacy, web site said no support, may be bad or counterfeit . Qcontrol recognize it and loaded firmware but I can't set it up due to errors on board. I have a friend who is sending a sd card with firmware already on it, who knows it might work. I not blaming vendor this is open source and I will fix it. So be prepared to hurry up and wait or buy a Naza as I have 4 of them

Good FC. Lots of documentation available online and easy to follow instructions. Can't go wrong with it. I've made 4 copters now and use a pixhawk on all of them.
