Hey @Peter T., I know you guys are disappointed at the fact that you aren't able to bring good avionics into your planes, but please, don't be so negative. It's okay to say that we can't bring you the best of what's out there, but it's not comfortable to anyone to hear you guys talk about your project as being bad. In fact, you are motivating yourself to neglect the project even more if that is going to be your attitude for the rest of the project(s).
I know this might sound like I'm bad mouthing the project (which I'm not), but I only wish for you to do the best, despite your possible limitations. Keep a good spirit!
