Harley,

While the motor used in the Reactor Bipe can handle the current you mention when fully loaded, it does not when using the recommended Reactor Bipe configuration. The recommended battery and propeller only draw around 34A max thus the 35A ESC is more than adequate for the job. The recommended setup delivers what we consider excellent power/weight ratio for this plane (over 160w/lb) so the motor does not need to be pushed to its limits thus running cooler and lasting longer.

I hope this answers your question
