Thanks for the link. I definitely don't want option 2 (unprotected trustfires). I'm willing to buy the IMRs you linked and would appreciate any link to a reliable seller and type of protected trustfires.
Regular AAs work fine, and Drac confirmed that the unprotected trustfires also worked in this Demolisher.
I don't know why those brick and mortar ones wouldn't work. The only thing I can think is if he left the thermistor in. Which...he shouldn't have and that's all I'll say about that.
I'd still ask him what motors are in there.
I've never bought from the site that I linked but from what I hear it's reputable. They sell protected Li-Ions (should be the same as a protected trustfire) here
as well as the previously linked IMRs, and they specifically list the length to be 51mm (um...double check the length on a normal AA compared to that one that won't fit in the battery tray...I think
that normal AAs are 50mm).
