This video is the first in a new series where we look at tuning your iNav plane. I you have seen the INAV Fixed Wing Group Wing Talk (youtu.be/MtXDbxbcsKA), you will know that at this stage I know pretty much nothing about tuning. So how can I help you learn to tune? Simple, we get a Marc Hoffmann. If you don't know Marc, he is a guy who is very switched on with iNav and how to get the best out of your planes. He is going to be teaching us how this is all done in a series of videos. I'm going to be the newbie and ask questions, which I hope will cover things that may not be so easy to understand. Of course, if you have any questions, leave a comment and we will try to cover these.
Please head over to Marc's channel and subscribe. He has a lot of great, technical videos. His channel is primarily in German, but a lot of his videos also have English subtitles. youtube.com/c/b14ckyysTech
