Compare Servos
So there I was, finding myself in need of a servo. After deciding on what sort of thing I needed; speed, torque, size, weight etc. I started to have a browse round the wibbly wobbly web. The choice soon became bewildering. "I need an easy way to compare all these" I said to myself. This is the web version of what I came up with.
It started as an exercise for my own amazement, but I thought maybe others might find it useful. So here it is. All the data I can find, for as many servos as I can find.
You can filter them by the fields you see in the form below & order them with the sort field.
I'll add more servos as I find them (& the time!). You'll find some data is missing, it too will be updated as & when I'm able. If you spot a mistake, or would like me to add a servo or feature to the database, please feel free to let me know.
Please bear in mind that this is running on an old machine sat at my feet under the desk & my internet connection is fairly slow by modern standards. This isn't going to be the quickest web site you've ever visited. You may even find that it's not working on occasion. I'll do my best to make sure it's up as often as possible. but please be patient.
Select the criteria you'd like to search by. Click on a field name for an explanation.
There are several fields you can't search on (yet).
Size
Entries are in mm. Some manufacturers quote the dimensions as Length x Width x Height, some as Height x Width x Length. Others seem to want you to guess! So, I'll have the script searching on dimensions just as soon as I figure out what they are & get them uniform across the database.
Travel
This depends somewhat on the radio equipment your using the servo with. Nominally a servo will travel through 90 degrees or so, 45 either side of centre, with a little extra for trim. Some servos are designed to go further specifically, sail arm winches for example will travel something like 140 - 180 degrees nominally. Drum winches can be from 1 to almost 4 turns, sometimes adjustable at the servo itself.
Some of the Hitec digital servos can be programmed, with a special programmer, for all sorts of things, including travel. Some radio equipment can also alter the amount travel, among other things. Servos can also be modified to increase their travel by replacing a few internal electrickery components.
All this make the nominal travel of the servo a little meaningless. I've entered 90 degrees for those that aren't specifically designed for more or less travel.
Notes
Space for anything that doesn't have it's own field or might make the servo a little interesting or different. This field isn't in the list, you'll have to click on the record to get at it.
Disclaimer
There had to one didn't there. Most of the data here has been gleaned from manufactures & distributors web sites. So it's going to be, at most, as accurate as that. I'm not beyond making mistakes either, so there are no guarantees. If you feel compelled to rush out & buy a servo based on the results you find here I strongly suggest you verify the information first. If your new purchase doesn't turn out as expected, don't go blaming me.
