I have being flying the Freeing F-22 Raptor 90mm Jet for a while now, I could say it is one of the best Jet I have flown so far this year due to its reliability and performance.
This uses 6s 22.2v LiPo battery, I used one with 80c and pretty much with any 6s battery you could fly this jet to its best. I have a GPS Telemetry Sensor (a speedo meter) attached to this particular Jet and clocked in at speed of 125mph at times.
