Quark 125b post thermal behavior

[natrix]

I'm still trying out gearing on my BPP LSP. With the Neu 1515 1y, 16/51 gearing and 4s2p 8000mah maxxamps packs...she thermals after about 1 minute of running. If I let her cool for about 1 minute...and then turn the epa down to 60% I can run her for another 5-6 minutes continuous, but she will often cut out. If I tap the brakes after she has stopped, she can go forward again. Is this normal behavior once the quark has thermaled?
