I bought a "like new" M-03 on ebay. Came with everything pictured but the RX, ESC and battery. I raced it last week at
RCAR Indy.
I learned that "everyone" uses aluminum steering blocks, so I will get those. Other immediate suggestions for hop ups? It was fun to race! But, the guys with the M-05's and M-06's were faster. No question.
I had fun painting two bodies for it too using Faskolor paints and my airbrush. The Honda Civic R from HPI and HPI's Scion body. The Scion is key lime green with an undercoat of neon green, then white. It really pops!
