I was able to setup a stock TREX 450 DFC V3 with an APM2.6. It worked great!
I going to slap that bad boy on a TREX 700 DFC stretched to 800. The helis are so similar. I'm curious how the scale will change the PIDs. Has anyone upgraded their heli this much? What can I expect to adjust on the PIDs? It should be a whole lot more stable but just as responsive. Any comments?
