So i've ordered a few pairs of the 3.7v Li-ion 3000mah ultrafire batteries for the flysky/turnigy 9x battery mod from dealextreme at us$12.58/pr. (don't flame me, this is before i realised there was a review panel at the bottom saying bad things on these particular ones).
since a pair would be 7.4v in 2S... would these be suitable as a receiver/servo battery in a 40 size plane? (kyosho 40 mustang). or they considered too heavy? or is the protection thing bad for running std servo's from?
cheers in advance
