RE: LR-1 Pylon racer
I think the only way you'd get by with 20C on a LiPo is if it was hanging out in the air. I have an F-18 that draws ~42A and the 3S 5,000 pack is ~130deg after 5 min and I put back about 3,000 to charge it. That's 36A average. It has some cooling too. I'll bet your pack will not last long.
