If you do get a fast charger... Hobbico MKII Is what I have also

Don't forget to use it on or after your third flight... It's good to have
a loaded volt checker... But you can't really go wrong with the above
info.. As long as you start off with fully charged onboard batteries..

I've been getting bad habits, and pushing my battery pack.. I.E. not
checking and not charging after the third flight as I was shown to do..
And I may have paid for it with a crash on the fifth flight(that day) on
unchecked and uncharged batteries even though the fast charger was
with me, as it always is..
