501s and 501ss

Post by tmaster50 » Thu Jun 24, 2021 11:51 am

I just purchased 2 of the 501ss. I'm concerned that they sent me the original 501s. Before I put them in the air, I want to make sure I have the 501ss. How am I able to tell the difference? Also, I haven't been able to find any info as to the size of the motors it has. Thanks,
