This item was bought as an 27MHz non-waterproof buggy. Everything has been upgraded to waterproof electronics. Radio has been upgraded to a new 2.4GHz transmitter (ECX9010) along with a new receiver (ECX9011 waterproof). Stock servo has been upgraded to a new and very responsive Losi 313WP (waterproof). The stock ESC and motor have been upgraded to a new Dynamite 15T brushed motor esc (DYN4925WP) and a Dynamite 15T motor (DYN1172). Stock motor was a 20T motor and the upgraded 15T motor makes this unit much faster than stock. Included with this unit are batteries, for the transmitter; new Dynamite battery (DYN1050EC factory sealed) and charger (DYN4117 factory sealed), for the buggy; tools, unopened original; shock spacers, unopened original; and original manual. This buggy has only been run indoors for a few minutes to test everything. It is fast! As you can see from the pictures this unit is very clean and in very good condition. Will be shipped in original box. !Needed items to complete: Nothing, everything is included! Just charge battery and go! I strive for 5 Star service and therefore, I do not sell anything that has not been tested for quality. Please ask questions before bidding since due to the nature of this hobby I do not accept returns. Will ship to US lower 48 only.
