The iCrimp Crimping Tool has become an essential tool in my arsenal for working on servo wires for RC planes. It's a game-changer that ensures a reliable and secure connection, and here's why.The precision and ease of use of this crimping tool are simply outstanding. It's designed to work with Dupont-style connectors commonly used in the RC hobby. The ratcheting mechanism guarantees a consistent and firm crimp every time, eliminating the frustrations of loose connections.I particularly appreciate the tool's ability to handle a range of wire gauges, making it versatile for various RC projects. The ergonomic handles provide a comfortable grip, even during extended use.Overall, the iCrimp Crimping Tool has made working on servo wires a breeze. It ensures that my connections are not only secure but also professional-looking. If you're into RC planes or other electronics projects, this tool is a must-have for achieving reliable and precise crimps with ease. It's a small investment that makes a significant difference in your projects' success and overall enjoyment.

I have all three of these crimpers and I recommend that plan. I can always find a fit in one of the tools and the quality is good enough that I have gotten to the point that I almost never mess up crimps anymore. I have not done any of the tiny 1mm JST crimps but everything else has worked well. I just keep all of them in the same place and I can always find the best fit. With the right size you wont damage the pin (especially the retention barbs) As long as I don't lose these I will probably never have to buy another crimper in my life time. Well worth the price and I heard enough recommendations from the 3d printing community that I was confident that I was making a good purchase. And they were right. I also recommend a lighted desk magnifier since you don't appreciate how hard crimping can be on the eyes without one. If you have to crimp something (avoid it if you can) these are just right.

Suggested by WestHobbies RC. Awesome tool. Works great. Servo, esc, and transponder connections are secured. No more splicing and soldering to shorten wires.

I bought mine in 2021 and only used it a couple of times so I did not get enough experience until today when I started making wires in earnest.Mine does not form the O crimp properly, that being the one at the insulation end of the connector. I am using 24ga silicone insulated wire which is very flexible, tinned and all around excellent. But this insulation is squishy and while the O crimp I think is intended to go around the insulation I cannot do that or the insulation squishes out and prevents the connector from sliding into its shield.In fact it’s not an O crimp at all, it’s just a bigger B crimp. On mine that bigger B is malformed, I think because of a defect on the hammer jaw. (One jaw moves which I call the hammer and the other remains stationary which I call the anvil. The anvil forms the curves of both the O and B crimp except as I say they’re really both B’s).The defect is in the casting and looks like it forms both an inclusion and a drop out which is to say one bit of it makes the channel smaller and the other bigger but these are by very small amounts. I think the malformation distorts the way the material flows in the die because one half of the O-which-is-really-just-a-bigger-B is malformed and the other isn’t. The top loop is squashed so the connector will not slide into the shield and requires fussing with pliers to get the shape right.The only way I can get a usable crimp is by using the 28-24ga jaws, setting the connector depth as recommended, crimping it and then pushing the connector in farther so the O crimp is in the B hammer/anvil and crimping it again. This is done with insulation stripped far enough that it’s bare wire through both the O and B areas (about 5mm).The resulting crimps are consistent, very strong and insert easily.I have only used these on one vendors connectors (gikfun) which I got at the same time as this crimper and they’re excellent but they state in the listing they’re for 22ga wire (and I’m using 24ga). Mine had the same behavior with 22ga silicone wire, I just didn’t go far enough in testing to find out if the same double-crimp solves it.

I bought this based on a recommendation for properly crimping DuPont connectors for use with my Arduino projects and solderable bread board. Crimping those little buggers is definitely not intuitive, but once you find proper guidance on how to do it this tool is just great. The bottom line is the crimping works every time as long as you load the connector properly. But some specifics warrant special mention: the tiny ridge inside the clamping area that “catches” the wings of the connector when lining it up are what allow me to have a near-100% successful crimping rate. The other fantastic function is the ratchet mechanism that allows for keeping the connector held snugly within the tool while working to properly thread in the wire.I’ve only done maybe 70 connectors or so, so I can’t speak to long-term durability yet. But it sure seems solid.Overall a great tool that reliably gets the job done.

iCrimp! A little tricky to get small connectors positioned. But seems to make a good solid crimp.
