I'm glad I could be of assistance. If you take good care of the batteries - don't let them overheat when charging, don't run them dry when you'r flying, invest in a better charger than what comes with the plane - you should be able to make them last a year or more. One of my original batteries is working just fine after almost 12 months. Flight time depends a lot on if your are flying full-out or cutting your throttle back. At 1/2 throttle I can fly past 15 minutes on one battery. If you want to really be there for a while - take it up way high, fligh it glider style - take it up a ways and cut the motor and glide until you need to take it up again. There's a spot near my house that has decent thermals and I have flown for almost an hour this way. It had my plane so hight at one point that I lost radio control for a few minutes. T-Hawks are big enough that they can handle some wind - maybe up to 15 mph or so. No wind is ideal, but a little wind can be fun. I had my plane up yesterday (not a T-hawk, but similar) and was able to stall it into the wind and hang it there for a while. It was a riot!

Have Fun,
Lance
