Arrows Viper 50mm, Always A Blast But Built To Last?

Always a blast to fly but the EDF unit is the weak point on this bird and it is not easy to remove, be warned! Flying this on a 1300 3S which gives it a surprising amount of power for 3 minute flight times. Bet you couldn't guess I'm flying it with my Radiomaster TX16S and an FRSKY S6R?!
