Hello! I am involved with Rockdale Tiger Flight, a 501c3 youth aviation program. We are currently building a Zenith 601HDS and we are looking at our options for AHRS and GPS. We are seeking donations or cheap options, even just advice, for our panel. The panel has been a bit of a bottleneck to the project, and some assistance would be greatly appreciated. We were planning on using a stratux but a more robust solution would be better. We have looked at the iFly 740b, which seems to be a good option.
