I've seen this question come up on here time and time again, and even seen this solution given before but people still seem to ask. I've had my Phantom for around 4 or 5 months now and haven't balanced one propeller, never really had the need to, Phantom flew fine, and didn't get any jello. After a few of my recent crashes, breaking the gopro mount etc. i've noticed a bit of jello so decided to balance some props and see if it makes a difference. After seeing many 'hacked' together solutions for balancing the self tightening props like using some fuel tube which seems to fit around the balancing rod etc. i wasn't really happy using any of them. I found a thread on another forum where a guy makes a aluminium rod, with CW threads on one side for CW props, and CCW threads on the other for the CCW props which you can just use on your regular dulbro prop balancer perfectly. Even if you do not have a prop balancer, the rod balances the weight of the prop on the other end, so you can use a perfectly level table with a glass etc to balance. It cost around £8.50 delivered to the UK and seems like a very simple solution for balancing the self tightening props. I just sent a UK bank transfer, however i am sure he accepts PayPal as well.
