Swapped the 1104 on the Blade Torrent 110 for this EMAX RS1106 6000KV. My opinion:
1. Crazy vibration with the babyhawk props. I have to swap back to DYS/Racerstar 2435. I am a bit disappointed because the babyhawk props have more thrust in bench tests.
2. After hovering 30 seconds they come down really hot. As hot as stock motors do on 3S. I am quite surprised because the RS1106 is bigger than the 1104 and it's 6000KV vs 7500KV. I would expect the RS1106 to be at least less hot. On the same build my RCX 1304 5000KV aren't even warm after a few packs.
3. Instance thrust is amazing.
4. Efficiency is not improved at all, if not worse. I got less than 3 minutes out of them.
All in all I don't think it's a huge upgrade for the Torrent. They are okay, but I am not impressed.
