Default Why do I have 5 amps at idle?

I recently crashed my T rex 450. The motor seemed to have thrown a magnet and froze. I replaced the motor, and it is tight when trying to turn it by hand or by turning the gear. I have adjusted the clearance between the gears, and it doesn't have any affect. I have noticed that some of the larger motors have a similar difficulty, and blame it on the stronger magnets etc. I hooked my whatt meter and have about 5 amps when I first hooked it up until I add power, and the current drops to .1 amps and gradually climbs. The battery that was in the crash has been replaced with one that is good ( and tested in an airplane ). Is this normal. Should I replace my speed controller? I hate to just start replacing things if it aint broke!

make sure that your motor brake function is not enabled... otherwise i think your ESC may have been damaged.

Have a look in the Trex manual. It should be described there. (It was in my Trex 450 Sport Super Combo).
