I have two weeks b4 my shapeways stuff comes, but the 1250 wedges in between the mount points and will rest barely against the 510 pin mounted as close to the post as the nut can be, make sure its a shallow mitec, it also has to be mounted close to the post for the board to fit, there is just enough space to wedge the battery in the left over space, I only have 16mm for the board. it needs 13-14mm at its widest point (the balance connector), I worry that with the plug connected, I might be short 2mm but I can always wire the balance connector away from the board if i need too, which is likely. I may also have to wire the fire switch direct, but I'll have the parts to play with and see whats what. I am one of the least likely ppl on earth to post a pic, I dont do facebook or anything else. But I was thinking about doing a virgin build video for the youtube. lets face it, chances are I will screw everything up, but at least I'll learn something. I'll keep you up to date so we all can learn from my mistakes.
