I have on board read of several important items I will never fly without again...
1) On-board pack voltage - I don't know how many times I landed to plug in a voltmeter just to make sure.
2) RSSI (Received signal strength - no more guessing about "am I in range" - with this - you KNOW
3) Altimeter (well not essential but darn fun for glider of any kind) on one bigger E-glider
I see so many people on these boards mention Flysky9x/Turnigy/etc, I think I'm going to have to start checking them out.
