I am in several groups, on Facebook, for quads and there are a lot of Taranis users in the quad groups. Unfortunately, none of them have experience using a Taranis in an airplane.
I picked up a Taranis shortly after they came out but i found the Open Tx software very hard work, so sold it without ever using it to fly a model, so i'm afraid i'm of no help. I'd guess though that if you have got to grips with the Open Tx from the quads that using it on a plane should be reasonably straightforward.
Hi Stambo! Its aways good to see you around. I started this thread, looking for people that might be around to help me set it up...if i have troubles. Ive ordered an X9D+ and a TBS Crossfire. Should be here Tuesday-ish
