run time.
 

how much run time do you think i can get on a 4cell 5000mah lipo on a mbx5r with a 36-60-2000kv medusa motor

20-25 minutes depending on gearing, terrain, drive style, vehicle weight, ESC settings, battery quality, etc.

IMO 15-20mins. of course under the conditions Brian mentioned.

I run my 8ight-b with a Medusa v2 60mm 2000kv with my; SMC 28c lipo's, PQ 30c lipo's & NeuEnergy 25c lipo's, all net 18-20minutes approx race time.

ok cool thanks. im debating on converting my 5r from nitro to brushless. im just worred about run time. cause when me and my friend go out to drive we are there for like 3-4 hours and i know if i have say like 3 lipos i might not be able ot run the whole time since they take like about 1 hour to charge.

No, but three packs should allow you to run quite a bit.

Run packs 1 for ~20 min
When done, start charging pack 1

Run pack 2 for ~20 min
When done, start charging pack 2
Pack 1 is ~33% charged.

Run pack 3 for ~20 min
When done, start charging pack 3
Pack 1 is ~66% done
Pack 2 is ~33% done

Take a ~20-30 min break and start the cycle again. Of course, this assumes you have three chargers going at once. :smile:

well i have one charger but my friend has a charger that could charge the lipos. and also i only would be running for like 7-9 mins cause thats how long my friends nitro runs for. and then i would be cooling downf or like 10mins.
