Hello,

I'm planning on making an autonomous rover for a school project (flight controller, GPS and sonars) and I have a few things I'd like to know before buying the different parts (I've already done some research but haven't answers to all my questions).

I was originally planning on getting the APM 2.6, but I'm know considering buying the Pixhawk instead (There's only a 30€ difference). I understand the Pixhawk is more powerful than the APM but is that additionnal power useful for a rover or is it a bit overkill ? I've also read about users having problems with the pixhawk they did'nt have with their APM, is one more reliable/easier to use than the other ?

For this project I have a T2M RC Pirate buggy I'd like to use. The ESC is a Hobbywing Xerun 80 A, and the transmitter/receiver is the default 3 channel receiver with the trigger and wheel.

Is the ESC model a problem ? For the receiver I know I need at least 4 channels, so could I use a 6 channel receiver and the transmitter that came with a RC plane I have ( Axion AX-4 CT 2.4GHz transmitter and Axion Link 6-ch RX 2.4GHz receiver). The alternative would be buying a Turnigy 9x (and a ppm encoder if I use the Pixhawk ?).

Sorry if the questions seem dumb, but I'd like to know if I'm doing things completly wrong before buying the parts.

Thanks,

Luke
