When Curt Yoder at The Ohio RC Factory likened soldering to welding to me a few years ago I knew right away it was a job left best to someone with experience. Much like setting up a smart phone, or giving a proper order to Karina at Pro-Line.
Now that Ray at Speedy’s Racing Parts is an authorized Hobbywing dealer we decided to work together, along with Ralph at TQ Wire to show how Richard Metz uses he experience at getting a Justock speedo to properly interface with a motor. There is no I in that team and the reason is to get everybody out there running with zero issues.
Once I had the Black Justock in hand along with the White 13 gauge TQ Wire I made the trip to DJO Raceway corporate headquarters to bother Rich while he preformed the necessary work.
The first part of the job is to remove the wires that are already on the speedo.
With the iron hot a slight touch removes each and with a little work the excess solder that melts with that process. Once that is completed Rich tins, applies a small amount of solder, to each end of the wire and motor tabs preparing it to be connected to either the Justock or the motor after the correct length is determined for each tab. The same process is used on the battery wires for connecting the gold 4mm posts also available from TQ. I added the red shrink wrap included with the Justock on the positive as a just in case. All of this can be tedious for a couple of reasons and taking your time can prevent making a second order. If the ends are not covered they can create a weak or “cold” joint that may come off or cause excess heat leading to a failure. Taking your time with each step of the process can be the difference between measuring OR buying twice.
Now that everything is connected and each connection has a beautiful chrome finish it is time to stick the speedo to the carbon fiber goodness of “my” XFactory Cubed. Parma is the brand but I have no idea what else to tell you other than the backing is red and its really super duper. Once I clean the chassis with some alcohol, allow to dry, and then wipe again with a paper towel we digress ever closer to the finished project. After that I place the double sided tape on the Justock first and then take a lighter to warm it up, this does make it stick better and a side benefit can be burning your fingers. Once I set it on the chassis I leave it be for a couple of minutes to allow to tape to cool and set up.
After all of this you are ready to pull the trigger and some wheelies.
In my next installment I’ll look at where I end up on the settings for the Justock and how the cut gears from Speedy’s hold up against a 13.5.
