RE: Is 4000mah enough?
I am flying the Wind 110. Weight with the current 5000mah, 30C batteries is 9.25lbs.
I would prefer to get 9-10min flights which is what I was getting with the 1.10/1.20 engines on 14oz.
Maybe it will be OK to get a few sets of each. I would prefer the 5000mah, but I really would like to have a few sets to get started. I can save the 5000/30C batteries for windy days for more energy, more ballast, and a more forward CG. Unfortunately the 20C, 25C, and 30C batteries are all sold out and I've been on back order for over a month.
There are 15C batteries but that concerns me a little.
