RE: Extreme Flight RC 104 inch 100cc Yak-54 sneak peek
It starts out for the first few seconds at 7.2V but drops almost immediately to like 6.6V until the pack puts out the last 100 mah or so and drops to 6.0v before. Do not fly is typically around 6.3v for most people. However, with the ability to be charged at 4-10 Amps and no memory - I just top them off every few flights with no worries before I can even get the fuel tank full.
