Hello Teramax,
I played copycat and built a quad similar to your Tankquad.
The design flies out of the box very well.
I now have 2 sets of those t-Motor CF Props. One set 15" and one set 12" and all of those props were way out of balance,
especially the Hub. I had to add a really large amount of hot glue.
So my question is, how do u balance those props, which tools do u use. I used a magnetic balancer, but that cost me weeks to balance 4 props.
When i look at your pictures, i see no sign of any hotglue or tape, do u sand the props?
Thanks in advance
Johannes
