This model was a Christmas present from my son and wife. The canopy was black, so I made my own canopy using a combination of LWPLA and a custom Vacuum Formed Canopy with the addition of a pilot etc. Did this to make is as similar as possible in looks to my eflite 90mm Viper.
The CG as per the manual appears to be spot on and pretty much consistent with the eflite 90mm Viper. Running a 3S 1300mah battery it seems to fly fine, but I have a feeling 4S could be better. Will give that a go in a later flight.
All in All a fantastic little EDF that flies way better than expected. I managed to squeeze in 8 flights on this day.. This model was purchased from Metro Hobbies in Melbourne but if you simple search for Arrows Hobby 50mm Viper I'm sure you'll find it
