Well I went for the Hobby king combo stuff and ordered a 4s li-po to come with it as well
Now for me having a bit of extra power if required is always nice
Example I fly RC Planes so if the kit says 40-60 engine you stick a 60 in it you never go for the low end because you get into trouble the engine just doesn't help you out, not good and you tend to find you have to have the dam throttle nearly always at 100% to do anything. As for scale models bloody things can become nasty without the right power
And the ability to not race around at 100% is always nice but I'm aiming for cruising around 1/2 to 3/4 throttle should be good with the option to open her up
it will be running on 4s packs as my planes also fly on these and i'll 4 packs with the option to double 2 up to give me around 7800ma to play with
or on one battery 3300/3900/4000ma depending which pack I use
