Decided to add the CF driveshaft offered for the V977

http://www.banggood.com/WLtoys-V966-...-p-952635.html

Shaft weighs in at 0.47 grams vs the stocker at a porky 1.32 grams.

Fit up was simple, plastic green top retainer is a tight fit

Simple mod and should help with driveline shock loads, quick retrim of the servo links and fly time!
