The Jupiter Duck in it’s original design has a 25″ wingspan. I decided to double that to 50″. So the question came up about what motor / ESC combo to use. The wing without the power pod weighs just under 4 oz. So it’s going to be a light weight. The 200% Ducks that I found on the Internet did not have any information about power. So I decided to try a Park 400 motor. The recommendation is to use a 10-20 am ESC. The Park 400 comes with 3.5 mm bullet connectors while the 10 amp Eflite ESC comes with 2 mm connectors. Now what? As it turned out after a fair amount of internet snooping around I discovered 3.5 mm female to 2 mm male bullet adapters. Bought the last two on Amazon. Almost every 10-20 amp ESC that I found had 2 mm connectors. Just seems like the Park 400 should come with the same size connectors as most recommended ESCs. My 2nd grade teacher, Mrs. Schnitzer, used to say that solving problems make you smarter. They do. Embrace them.
The FT Servo Tester looked like a good idea when I bought it over a year ago. The FT youtube video shows exactly how to use it. The tester has been sitting on my bench waiting to be used. So today I went to use it and discovered that the tester that I purchased is not quite the same as the one in the video. No big deal. The pics below show how to use this model.
If you have one of those nice soldering stands with the magnifying glass and alligator clips, but can’t find it, here is a work around. Take a couple clothespins and hot glue them to something heavy, like a paving brick.
In a previous post I talked about strictly using Powerpole electrical connectors. The only problem that I have encountered is when I try to separate two connectors. When putting them together one slides up into the other using the slots on the side. Sometimes when you try to reverse the process it doesn’t work so well. So I use a couple of pliers or a small channel wrench. Works great. Haven’t broken one yet.
Never liked to solder. When I first started flying electrics I was using Dean’s connectors. And at some point you probably need to solder connectors to ESC’s or batteries or something. Many years ago I discovered Anderson Powerpole connectors. I was attracted to them because NO SOLDERING!. The connections are crimped instead. If you have ever used a wire crimper before you can figure out what to do. If not, there are many Powerpole tutorials and how-to’s on YouTube. Besides not needing to solder, the other benefit is that while very secure, they are easy to connect and disconnect. You hear a little click. And after more than 15 years of using them and many hundreds of flights I have never had a problem.
