I have purchased many ( Actually the Majority ) of my batteries from value hobby.
80% of the batteries I own have the GForce logo on them.
That's I guess why I was so disappointed when my 30c 3 cell 500's gave me the flight times
that I get from worn out 25c Gens Ace 450's .. I was fully expecting to get 6 to 8 minutes of flight time from these packs and the most I've gotten so far has been 4:15...
It has been several years since I purchased any batteries for my WMparkflyer MX
The last time I bought them they were 4.50$ per pack now there nearly double that, not quite.
I am used to 6 min flights of full 3d .. these Batteries only give 3:30 minutes of solid 3d performance.
a true 30c pack at 500mah on this plane should swing that prop for 6 min easy. I am by no means done trying this brand but now I'm a bit Leary of the numbers on the label. (Posted on 5/26/2016)
