I can't remember if i read a post on here or one of the other forums about this balancing rod for the self tightening props: http://www.ebay.co.uk/itm/DJI-Phant...sGames_RadioControlled_JN&hash=item20e6c1e3a6 Anyway, i bought one from the eBay seller i have listed and it works perfectly with the Du-Bro balancer. I didn't realise that the standard props would be so off balance. Five out of the six i have tried needed balancing. Anything that helps my V+ fly to its fullest is worth it in my opinion !!!
