I am building a remote control airplane, and naturally the most complex aspect of it is the electronics. I don't know if I should use the Arduino microcontroller or try to build my own circuits that only do one simple thing (I am using commercial electronic speed controls either way for the motors). I need to communicate controls and LARGE streams of data (air quality testing; ). I already have air quality equipment. I am wondering if I should even bother or just buy pre-made everything. I want to learn as much as I can, but I also don't want to take on a task too big for one person to do. Cost is not a big deal (within reason), as this isn't something I am paying for myself.
