First design, when did you get it? That is VERY different from the LSP mount that I got last spring and hacked to fit my lightning buggy.
Here's a pic of mine for comparison
Hot Bodies Lightning 2 Pro carbon, Mega 22/30/2, MMM, 4s3-5Ah.
Tamiya F201 carbon, Mamba 7700, MM, 2s A123 2.3ah.
Xray XT8, 1518, MMM, 4s5Ah.
Lots of boats.
