Cheerson CX-20 RC Quadcopter Parts Propeller Prop Fender Bracket Set
A part of the review has been auto-translated.
I have the Quanum Nova, same exact quad as CX-20. When landing the gear can be a little bouncy at times, and tip the quad on end which results in the props getting scraped. Even on grass this is something I do not want to happen. However, on asphalt/tarmac it is really a bad thing to have happen so I installed these prop guards. The weight is insignificant. They look great, and increase the 'size' of the quadcopter dramatically. I painted small sections of the undersides red and green to help with visual orientation. These are well worth the cost and I recommend them to all CX-20/Nova owners.
Great not to chip or snap a blade will remove once I get handling down but already tipped on concrete and these saved the blades, painted mine bright green check out the pic.
