interesting, I saw this on HobbyKing recently and thought the design looked familiar. Mamba Monster dressed to look like an RX8... also interesting was the OEM jumper wires
Also, HK claims the weight of their Trackstar to be 88g. Castle says the Mamba Monster weighs 121g. Copper, gold and even aluminum are heavy...their dimensions almost exactly match up, so what exactly is(n't) in the knockoff?
