Overall I think they are good for the app and the batt fits well on the stock chassis. Runtimes won't be huge, but you should clear at least 10min on the track. They cost so little its very affordable to have several packs. I got good power out of mine. I was doing 45ish on 3S and 60mph on 4S on the original LMT 3100kv motor. If you use too big of tires and gear too high you may start pulling too many amps and the batts will get warm. Count on 800-1000W max. Still quite a bit of power for a .5, but won't be uncontrollable.
My lmt croaked and I decided to go with a 2200 medusa and use 4S versions of the 2200s for a bit more power ceiling and keep things very cool. Quite happy it either way.

BTW: the vid I have below of the .5 racing @ the barn was on a 3s 2100 pack, but with a crappy feigao 2700kv S can. Still fine power, but the medusa you have will have more punch and power. Was ending the 7min race w/ ~1600mah used IIRC.

Thanks for the tip and the vid! I might end up w/zippy's...prob.is that they won't fit in my batt. tray...
