I'm going to wait till someone posts some speed numbers before deciding on the Aon or the Mamba. I saw a Mamba 8k in my Friends Team Associated 18'th scale truck, and WOW. It was amazingingly fast, on the stock battery! We also weighed our trucks at work, his was 1.43lbs with battery and aluminum kit. My MLST was 2.26lbs with battery, stock.
