The prob is the Vendetta and MQ-SE's batt compartment. The DualSkys fit like they were made for it. Most batts are too long and/or too wide - no bigger than 33.8mm wide x 89.9mm long. I can (and have) made extenders to let me run thicker (2 -1700s is a killer combo) and the integy's are a touch tight but fit and don't move. Integys also fit real well in the m18mt and my m18. They're short and def overrated as far as mah goes (more like 1200) and much lighter than nimhs!

Most everything is too long unless you want to run 700-800mah which I don't. I've just found the 1345 FP EVO will fit, but can't find them in stock anywhere. Apogee has talked about making purpose built 1/18 but never delivered - think their shortest is 105mm.

skellyo - I replaced mine with another pr of DS 1700 that were labeled Vampower I got from Jaime at Starluck. They are the older, higher rated ones with lower C rating. The newer (same physical size) are 1300s, but 25C rated. Airplane guys love em! I plan one getting a pr of these as well as soon as I can catch them in stock.
