Tried my 450 with the keychain camera - no matter what I do it's hopeless
So - I mounted a GoPro underneath it and gave that a spin. Difference is night and day. A bit of vibration but no jello. Looks really decent
I'm assuming the keychain camera is simply too light and gets bounced around - maybe if I superglue it to something heavy and then mount it under the 450 it might be ok?
James - if you read this - when you balance the props - by sanding - do you sand the top or the bottom of the prop?
