Garrett

I bought my Garrett together with some extremely lightweight servos. These servos used funny little grey connectors, and my receiver had matching connectors on wire extensions. I found the servos to be less robust than I enjoy dealing with and decided to stop using them.In order to be able to use the receiver with other lightweight serovs such as the FMA S-70, or Hitec's wonderful HS-50's, I needed to modify the connectors. Mr. Garrett option for this uses a connector block with attached to the end of a short wire bundles. This seemed needlessly heavy and not sufficiently elegant for such a nice, light jewel.
What I came up with has these benefits:
There are 2 issues to consider before you attempt this. The first is minor, the second much less so:
- Fits (mostly - see below) all standard servo connectors (except the old Airtronics ones).
- Lightest weight - the total weight of the rx as shown is 3.5 grams. I wrapped mine with light foam tape and heat shrink for a total weight of 3.9 grams.
- VERY compact.
- The block has a solid mechanical connection to the pcb.
- Hitec and JR connectors will plug right in. For Futaba connectors, the polarizing key has to be ground off. This means that in the future you will have to be careful when plugging in to other receivers. This is fairly minor.
- The more significant issue is that this is not a very easy thing to do. You should feel very comfortable with a soldering iron before you attempt this. Given the small size of the receiver, there's no room to slip up in, and carelessness can have dire consequences.
Close-up of the top. There are 2 rows of 6 pins each. The ground pins are the 4 outer ones. The positive pins are next in, and the signal wires are the four center ones. I will add some pictures that show this better. For now you'll have to make do with this crude diagram:
