What makes the Safe2Fly unique is that it uses voice to inform the pilot of battery status - not a display, which can't be viewed while flying.
You can also purchase a Safe2Fly with inbuilt height monitoring, with a programmable height ceiling -- making sure you don't exceed any height limits. The Safe2Fly with height can also read out your current height with the flick of a switch!
The Wireless Copilot system was designed by miniature aircraft enthusiasts to take your hobby to a new level of enjoyment. The problem with LiPo battery powered electric models is that you get very little warning when the battery goes flat. You either have to land early reducing your flight time, or risk a dead stick landing - which often results in a damaged model. The Safe2Fly measures the energy used, and reports this back to the pilot real-time.
