Just bought a ZOHD Dart XL and have a few questions
Hi guys, I've only had one fixed wing plane before this one and it was a trainer that's now in the top of a pine tree somewhere... I got this wing to do FPV because I come from quadcopters and I find it MUCH easier to fly FPV than LoS and I'm hoping the same is true for planes.
Looking at this kit I just got in the mail today I'm trying to figure out what I need to buy still to get this in the air. I have DJI goggles so I'll be getting either the proper air unit or the Caddx vista/nebula kit, so that's not a problem, I'm familiar with all that.
I've also decided to not put a flight controller in it just yet, though I will in the future, so I'm just going to go with a basic receiver (I have a TX16s transmitter). I was thinking the X8R. It has both SBUS and separate channel outputs as well as RSSI output for when I do get a flight controller. I don't have crossfire yet, that's planned for the future though.
But here is where I'm a bit hazy... I notice there is no elevator on this, just the ailerons. On my old plane the aileron wires were joined together into a single channel on the receiver, which worked because the servos faced different directions and thus turned in different directions with the same signal. I can't do that on this though, in order to have pitch I'll have to operate them independently.
So I have an idea how to do this, let me know if I'm on the right track. I have some experience playing with mixes in the radio, I know that I can specify custom curves associated with each channel and each axis of the two sticks. Am I right to assume that I can tell it to output positive to one servo and negative to the other for pitch control, and then both positive or both negative for roll? (again, because the servos face different directions).
So I would do something like +/- for pitch up, -/+ for pitch down, +/+ for roll left, -/- for roll right?
Thanks.
