Nick,
I only have about 20 flights on mine now but it is tuning really quick. I have a raptor 50 as well but this thing is getting to fly just as good. Right now i am burning 250mah per min. in flight so 5-6 min flights should be very do-able charging with a cell pro means only have to have 3 packs and i'm good for this little bad boy.
Good luck at the Shootout BTW i hope to get out there but will see.
Take care.
