Flycolor猛禽迷你30A BLHeli多旋翼ESC 2-4S（OPTO）
Really not a bad ESC, small and light. For the price OK.
But, 1 of 4 was faulty, so I think the quality is not the bestI replaced some simonk ESC's with these, and they are so much smaller, and yet give off no heat, and are just as effective. I had a problem knowing how i could flash them to Blheli 14.8 but if you connect them to a Naze32 and use the passtrough to Blheli it works, and was painless. Overall very happy with them and i would buy them again, but as i bought them in the sale, the current price is a little high.very tiny with a nice range for batteries.I purchase four of these for a DIY quad. After installing them, one was bad. The motor would only shutter. I ordered a replacement. It took twenty two days to arrive. I installed it and found that two others were bad. One was lazy and would not come up to speed. The other would not start without spinning the motor by hand. It was then much faster than the others. I recalibrated several times and came up with the same results. HobbyWing would not refund because the wiring had been modified for the fit. The product looks great but the quality of the ones I purchased was a waste of money. I replaced them with ZTW Spiders and they work perfect.I'm using this ESC on an RC Factory Big Crack Yak 39" span 3D plane. At first I was hesitant to use a multi rotor ESC but the very small size and weight won over. I always use a separate BEC on my medium to larger size foamies so this ESC being an OPTO didn't matter. I like the instantaneous throttle response that makes it perfect for hovering. This ESC controls a Park450 powered by a 3S 1200mAh 25C airsoft battery. Max amp draw of my set-up is 18 amps using an APC 9x4.7 SF prop. The ESC is just warm after 3 minutes of constant hovering and never got hot after a full 7 minute flight. I like having a little reserve in hand and this 30amp ESC is perfect as it is much lighter than aircraft style 20 amp ESCs even with a separate BEC added. Yes it is 8.5 grams and I will be using this ESC on all my 3d planes.Have these installed on my Y6 powered with 4S, running on Multistar 4108-480 and spinning 17X5 carbon props. Previous ESCs (9192000124-0) were getting much warmer on this set-up which means energy of the battery was converted into the heat. These are getting slightly warm so less power loss. Oh, and they fit into 16mm booms perfectly.have flown my 19 inch (diagonal between shafts ) auw 1.25 k on several test flights -
14 min on 28deg c day - esc's only slightly warm . I am very pleased with the way the
esc's fit on my 19mm arms . So yes - worth trying .This is much better than my previous ZTW 18a.. esc not too warm with my 4s setup 5045 2300kv.. easy to flash via cleanflight to update firmware, value for many and good performance :))
