The drone is what we call an RTF, meaning it is ready to fly as soon as you get it. When opeing the carying case, you will have the nice surprise to find your drone already all assembled and ready to go for a flight.
This is not always an evidence in the field of drone racing as many users are more the do-it-yourself kind of user. This way, the R Racer is also addressed to the less initiated as it is completely assembled with its motors and FPV transmission system well in place. Screw the propellers on the right spots and your drone is ready to take off.
