With my 550 4.5 Reedy sonic and same battery, I can do almost 15 minutes. havent gotten a full run with my 5200 saddle in yet though.
6 minute 19sec laps high traction indoor.
on the 1/8th scale track i run its 8minutes and 25sec laps loose.
It actually runs cooler on the bigger track.. Surprised me. But I'm running a boosted 8.5 and I run the same gearing on each track. More gear doesn't always make people faster. I run 11/62 if i need more speed i add timing/boost. not gearing. adding timing or boost is like adding rpms so it will wind out much better. my boosted 8.5(5200) is faster than my tekin 4.5(4800) 550 with same gearing just less torque.
