Saving some weight...
I am waiting on my replacement Multiwii FC from Witespy, who is notorious for taking a while sometimes - and at this time is asking for "your patience" for delivery times. So this could be awhile...
Couldn't sit around waiting, so I decided to bring a couple parts to the shop and try to shed some pounds (or grams as it were) on the frame. I am not sure why this frame is so heavy - there really isn't much to it. But at 650 grams for just the frame alone, I figured a diet may be in order (better the frame than me!).
The photo below shows one of the glass frame parts pre-drilling - which already had some holes cut into it. I figure this thing only holds the FC, which weighs nothing - so it could have a few more holes...
Took it over to the drill press, and cut a few more holes to lighten it up. It didn't take off much, but at this point it seems every little bit helps.
Not really sure what else I can do to take off weight. I thought about using the milling machine on a spare set of arms I have - to see if it would retain its strength but lose some weight there. But weakening the arms seems foolish - and I am not sure how much could be gained...
While I was at it, I modified the custom battery tray, taking off a slice from the side - which means that the velcro straps will now hold the battery tighter. Also drilled some more holes for weight loss.
