First thing to do when setting up any plane is  to set up transmitter to output 1000-2000 us pulses, with 1500 us at the mid-position. Then set all the servos to their respective  mid-positions. The servo horn should then be perpendicular to the housing (within 1 tooth snap of the horn), except for the servos for the flaps, if applicable. Those last ones will generally be at the flaps up position. The left servo horn could maybe be turned clockwise by one click This ensures equal control surface deflections in either direction when anything else than mid-range is output, and symmetrical deflections of the control horns, and therewith control surfaces, w.r.t. the mid position. Aileron pushrod Flaps servo The next thing is to align control surfaces by adjusting push rod length. For the flaps, the adjustment should be done in the flaps up position, ensuring that the servo does not make a buzzing sound, while the  flap surface is as good as possible in lin...

What could be easier than binding a receiver to a transmitter, right? Push the bind button while powering up the receiver, put the transmitter in binding mode, wait a few seconds, done! Well ... With the FrSky S8R receiver, there are a few "other possibilities"...

As I wrote before, so far i've ordered everything I used from Chinese web vendors. The argument initially being the price, of course. I did not want to invest too much in a project with an unsure outcome, if that's not necessary. And in my case, there were many possible negative scenarios, making this a sort of high risk project. I did not know if I could pull it off, software-wise. I had some confidence in me getting the mechanical part sorted out. But then, if those two would come together, I did not even know if i could fly at all, or if I would like to fly such an apparatus. Or if I would continue to like it, once the challenge of getting things to work would wear off. But since my experiences with those Chinese vendors was positive all around, I continued to order from there to this very date. I have only once not received an order (out of some 200 orders), and that was settled with a refund after only two messages. Also, I received something different than I thought I...
