SoloGood 10 Pairs Amass MR30 Male Female Connector Plug for RC Multicopter Airplane

Perfect solution for drone motors. I use them on everything now and this particular set has proven to be of great quality. You connect one set of leads to your 4:1 ESC, then attach them to all your spare motors. Motor swaps become a 1 minute ordeal. But wait there's more! The true genius of using these is that they become a heatsink for all the heat generated between your ESC and motor. And since they end up sitting right under your props, they get continuous cooling and heat dissipation. This summer has been brutally hot where I live. Yet after burning through a pack on the racetrack my motors and ESCs will be lukewarm while these connectors will be much hotter. This is of course what you want. All that heat away from your expensive parts, and bound up in a 50 cent connector that is getting continuous cooling. I burned up 3 ESCs in April when the weather was mild. Since adopting these connectors on all my builds all of my ESCs have held up to the heat of summer. And for those of you who may be concerned, the additional weight is almost negligible. A few grams for a set of 4. Well worth it to preserve your gear. Can't recommend these enough.

used these to hook up some drone motors. worked very well. happy with these connectors. they are small so check wire size carefully.

Arrived quickly and are very nice quality connectors. They are light weight and about the same physical size as the xt 30 typically used for 2s applications. They work well for motor connections to ESC or even battery power connections for medium to high current applications.

I use these as a quick disconnect system for my 3" quadcopter motors. They're much cleaner than straight bullet connecters and have held up after many crashes. If you've got groupings of 3 wires that you need to be able to quickly and securely disconnect and reconnect, these are for you!

Bought these for quick swap of motors on my racing drone, perfect size for the arms. also prevents prop strikes if placed properly on the arm.Definitely will buy more from this seller.

Value for the money

Connectors are great quality and shipped quickly

I bought these for wiring up a BLDC outrunner motor. They are smaller than I expected (nice surprise), and are rated for 15A continuous (30A peak) and are gold plated. Quality is very good all around.Note that they hold really tightly (a good thing) which makes separating them a bit tricky, made worse by the fact that there is very little to grab (just some token ribs and some debossed "grip" areas). But, they will come apart if you wiggle them a bit. This is much better than the alternative (falling apart or vibrating loose) as these connectors don't have any positive locking feature.Soldering these buggers takes some skill and practice. I've found it very hard to get 16Ga wire into them, 18Ga is much easier. I've done both the "fill the solder cups first" and "insert bare wire and solder after" approaches. Both methods work. One tip is to mate the pair when you are soldering the Male side as if you add too much heat the pins can drift out of alignment. This is less (non) issue with the female side as the sockets are fully supported by plastic, but mating them couldn't hurt when you do that as well.Another tip: get Silicone jacketed wire. PVC jacketing melts too easily as you need to use a lot of heat to solder these pins. Amazon sells a bunch of Silicone jacketed raw wire from "Striveday" that seems to work well with these.I've not found the heatshink tubing necessary as the backshells (don't forget to put them on first!) have a divider that keeps the haywires from contacting. I don't think you could get the provided heatshink on 16Ga wires, maybe a chance with 18Ga or smaller.The protective backshells are kind of difficult to install - you basically have to pinch them on with a pair of needle nose pliers or similar, and try not to mangle them too much doing that. you can't have any extra solder blobs on the connections or the shell won't go on and stay on (one kept backing off on me).But overall, nice little connectors. I bought a whole bunch to keep around for prototype builds.
