Yeah, the Pi moving to full computer thing is weird because the SD card is still a massive bottleneck on normal day-to-day usage.

Will you use a separate flight controller chip or try to do it all on board?

It’s been a while but I remember Orange Pi having terrible support? I haven’t heard of the others.

Whereas the RPi has the amazing compute module if you need it too.

Sometimes paying more is better.

What are the better options?

Pis have great software support so for GPIO experimentation it’s so useful.
