Stickmangav Not that I know of, but I use them to hold an expensive Nikon action camera and I do give them a thrashing. I bought the pack of 4 and I am still using the first strap. I have tested to peaks of 26g crashes.

Stickmangav Hi ...just measured. Relaxed the thickness is 8.15mm and pinched about 7.90mm with 5.04mm internal hole for shaft clearance. My Samguk Wei motor says it has 7mm useable shaft length,but in reality (like most brands they have about 14-15mm of shaft total. In my case, with a the supplied flange nut it tightens leaving 0.8mm poking out the top. Slightly thicker than my Dal Cylone props at 7.85mm but no issues. Sorry for all the numbers, but hopefully some of them will help. Best Regards, Gav

Stickmangav 118g all parts for my build ...this was with the action cam 30deg carbon plates for fpv camera mount and minus a black PLA bit for an ariel ...and the non slip battery pad.

Stickmangav Hi, I was a little confused but ...under the price there is a picture for each type of card. Click on one and the main picture changes and the price updates. For each price you get 1 card.

Stickmangav CMOS ...cdd is very rare in the competetive market. I only use them for making microscopes nowadays, not fpv.😎

Stickmangav Yes you can. As a safe guard I have tested more with an opto isolator switched hobby relay and it works all day. It means I could power anything (as long as it meets the output spec of the relay). I also got it to run on 3.3v making it fun for kids projects using 2 AA batteries. 😉
