I'm New Here
Having started a few years ago I'm just now finishing the panel. I purchased a Nav Aid years ago and just took it out of the box. Just wanted a few opinions regarding using this or should I update to the EZ. I"ve had a bit of trouble setting up the servo, but I think everything finally clicked today. Anybody out there I can question about the installation I'd appreciate hearing from you. CRW in TIST
