The 4 inch FPV racing revolution is coming. The SuperLight 4R is here to lead the way. This craft is a departure from conventional thinking with regard to what is possible from a 4 inch racer. It is also a departure from conventional thinking with regard to the proper electronics setup to get the most out of this little beast. Please review our RCGroups discussion about the 4R below and also pay close attention to the required electronics setup link below. Yes, a 4 inch craft can be faster than a 5 inch.

We can ship to almost anywhere in the world! Available international shipping options are using United States Postal Service (USPS) or DHL. USPS shipping will be per the flat rate option.
