    Well i bought my used but still in good shape other than i need to replace the dean connecter on it but i know it will get at least 20 min . But really to even get close to 25+ runtime you need to be smooth on the throttle. In to most of a long main than when it gets closer to the end than go balls to the wall ! Other factors of course also heat, drag etc.

    Oh yea theres a RC8TE tread on this site on the bottom of the page.

    Man nobody i know of thats makes a mah that high . Maxamps has 11,000 mah 4s now but there not cheap new thats for dam sure ! Best to buy a used one from a racer i got my 10,000 mah 4s for $125 ! I change it at 5 amps it takes about a half hour for a full charge and i used a Skycharger 200 amp charger it might be because i need a higher amp converter than 19 amp.

    There is a company called True RC and they make a 8000mah 4s but the C" Ratings are really low there 10c and i had a chance to try out one from a guy i race with it was bad the punch was really lacking and it made my motor overheat . So inless you have a fan on your motor i dont remmend that lipo .

    Oh they are especially there lower mah 4s lipos i wouldnt pay that much for them . I got lucky buying my used from a guy i race with or it would of been $289 !

    But you do get a year warranty on the Max Amps lipos and service.

    You can run a 5s on a 2000kv or a 2200kv just watch your temps and gear down oh it will be faster than a 4s ! If you still have the Assoicated conversion kit you may have trouble laying it flat in the tray without modeing it . You can side it on its side and strap it down but that will efect the CG .

    Hobbyking sells Nanotech 6000mah 4s lipos there out of stock right now but for a main it would give you at best 15 min. But for 20 min or longer a high mah 5s should give you enough runtime im thinking .
