This is the Futaba 4PK Pistol Grip Transmitter and the R604FS Receiver with the 2.4GHz FASST system for surface use.
Servos are not included.
FEATURES:
Futaba's FASST (Futaba Advanced Spread Spectrum Technology) shifts very quickly virtually eliminating signal conficts and interruptions unlike other 2.4GHz systems that only stay on one or two frequencies
Dual antenna diversity enables FASST system to automatically and seamlessly select the best reception between the two antenna built into the receiver ensuring that model stays under constant control of transmitter regardless of altitude
Pre-Vision Packet Screening technology scans incoming data for potential problems and applies sophisticated error correction techniques for solid impenetrable link with model
Easy Link system features a unique ID code in the transmitter that links to the receiver insuring that receiver only follows commands from this transmitter-with over 134 million possible codes there is no chance for a conflict
"New Driver" "Race Ready" "Expert" and "Big Car" menus that add functions based on skill level and experience
Throttle Mode Select for selecting acceleration/brake servo neutral points between 70/30 for nitro or 50/50 for electrics, throttle programming options including 5-point curve, expo and VTR
Slide the power switch to "display" to set up without transmitting- use one of the four menus provided or create a custom menu, optimize response for analog or digital/brushless servos, set up two sets of dual rates, choose two Condition Select functions, restore factory settings with the adjuster function, or adapt electronic speed control to HRS frame rates with MC link Traction control/acceleration rate
