[NSRCA-discussion] E-Question HXT motors

[Emory Schroeter]

Hey Anthony,

 From my experience, I was amazed at how well the HXT motor performed.  
I don't remember the stats exactly, but they were very close to the  
performance I was seeing with the AXI. I believe it was slightly less  
efficient (maybe 2 more amps drawn) and had about 200 less RPM than  
the AXI. Like someone mentioned, I kept waiting for it to fail, but it  
didn't. I had well over 100 flights on it when I decided to plant the  
airplane in the ground. Based on my experience with it, I wouldn't  
hesitate to try one again in the future. I mostly used the APC 20x15  
prop.
