20 years of aero-modelling so had a tidy up of several boxes of 'junk' and found a ChangeSun 12 blade 90mm EDF fan with a HET 1400KV motor and 120A OPTO ESC. Needed to put it in something and I liked the look of the FlexJet Pro. Turned out it was a very high quality kit with excellent assembly instructions. First flight on 8S4000 was good although one mains door hinge did get pulled out and landing on the slightly bumpy grass. Easy to repair with some epoxy. Looking forward to more flights in warmer weather.
