Sorry for the short flight pilots. The 300mh 4s Spektrum battery that came for this plane is a dead soldier. Voltage was dropping dramatically under throttle so never got to see any real throttle speed. Good thing it wasn't too windy yet, as there may not have been enough power for return against any wind. Was flying on low rates. See you soon with a better battery and see what this little thing can really do. Thanks for stopping by.
