First of all i want to thank all the members for supporting and guiding me by clarifying my questions no matter how trivial it is.Now i have a clear idea over my airframe design,i am going for an airframe with inverted v-tail(ruddervator),and without
Read more…I'm relatively new here, so please forgive me for asking what might be a dumb question. But any insight is appreciated.A little research demonstrates that the amateur use of drones is 99.99% DIY. There's really no way (that I have found) to buy an of

Now that the ArduPilot is available, I have a few questions about using the FMA co-pilot.1. Is it really necessary to have the proportional aux channel on a TX? Alternatively, the trim can be set on the FMA computer. I imagine that having it on the T
