The Riot should fair well compared with the GT and Losi. The big difference is the 1/8 scale tires that will climb where the others cannot and has a larger contact patch for greater traction.
As for radios, the Airtonics radio that comes with the Schumacher RTR kits is nicer than the radio that comes with Associated RTR`s and comparable to the Losi`s JR radio system. All these RTR`s come with AM radios. If you want something of higher quality, programmable and FM, then we suggest the Airtronics MX3 radio system that we offer. This way you can purchase the Almost-ready-to-run Riot and add the FM Airtronics MX3 radio for a total cost of only $50 more. (We offer the MX3 at a discount with the purchase of the ARTR kit)
