Hi Neal
Still looks good - a bit of vibration I'd say rather than 'jello'.
I mounted the GoPro under the 450 and the results were good, but not rock steady - still that tiny vibration on hover -.like on your vids. I think I need to balance my props by sanding them - I assume you can sand the plastic ones?
Are your vids with perfectly balanced props?
I bet they would be better with sunnysky motors too - cant get over how smooth and well balanced they feel on the bench.
I've also read about vibration damping between the arm and motors - although I've not found an off the shelf product / solution you can buy.
Looking at GoPros - cant decide - too many to choose from - might pick an older one up on eBay. Although the v3 is lighter and smaller - which would be good
