I’ve been experimenting with 3d printed frames here’s my latest design weighs 11g small advancement on the last on which weighed 14g
What size is that frame? If you are going lightweight, try somewhere between 75-85mm square frame. Looks good!
It’s 83.5 mm
You could probably lose another 1.5grams by losing the radio tray… No need for it. If you do need one, I would then at least perforate it to reduce weight.
Otherwise, really nice design.
Yer I have been thinking about mounting the battery on the underside and losing the radio tray
