This is going to be a small series of me assembling a ZOHD Talon GT in an INAV configuration. I have the Talon on order already, and am waiting for it to arrive. Banggood was kind enough to supply me with a MATEK F405 WING flightcontroller, a Ublox M8N GPS , and an FrSky XM+ receiver to test this configuration 😁 The Talon was paid for regularly, mind you. Just to be clear and transparent on that. This makes an INAV configuration possible, but the most obvious next step would be to introduce a long-range transmitter module / receiver combo. The XM+ shoud have a decent enough range to fly line of sight, and maybe some FPV, a little further out, but an FrSky R9M setup (ca. €100), or even better: a Crossfire setup  (ca. €200), would be the way to go for this type of flying. I don't have those yet, so donations are always welcome! That can be as simple as clicking on any of the (affiliate product links in this blog, and ordering something from those stores that are linked. It do

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 line with the win

Rebuilding my Durafly Tundra took longer than expected, and the result was not good enough. So my plan was to do things right, this time around, and get new parts wherever needed. That ended up in me buying a new Tundra all over again...

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"...
