How do I best set up my planes before maiden flight, and how do I get the best results when I maiden? I will have three planes ready to fly soon on a new transmitter, and my skills are still pretty newb level. One is a mini scout, two are custom. For those not following the build-ruary challenge, I'll include pictures and brief descriptions of the scratch planes. One is a four channel twin boom trainer with elevator and ailerons. The second plane is a high alpha park jet/fun flyer of slender delta configuration, three channel,elevons. I'm still figuring out the best way to mix the trainer. The delta mix is a preset but I am very concerned about how much expo I will want on this one, because the design has a very sensitive roll axis. I flew this design great forward and up on a transmitter with no expo, except I could not turn without rolling into the dirt. My transmitter can also do dual rates. Will I want to use that function?
