mugen
i have the mugen and the 808.
i thought of selling my 808, but to see people buying them for half the price makes me feel ripped off.
anyway. i do agree the mbx6 is bulit like a brink, i was lucky to get mine before the price hike so managed to buy it at 350£.
the 808 is awesome, u wont need to modify any thing and make it heavier.
only thing is probably the quick change mount, if u not keen , just make sure u lock tight all the screws surrounding the engine.
it will loosen and eat the spur gear
