I was going to attempt an electric RC plane project this summer and I was stumped on how to get the control surfaces to move without requiring a heavy servo. Are traditional servos common in small RC craft or is something less conventional used? I was expecting to find something about the size of a pager motor, but obviously with a little more control and torque. Any ideas?
Okay, I checked out the tower website. Are **broken link removed** the type of servos you were talking about, or do they go even smaller?
For the plane, the layout is very vague at this time, but generally I was hoping for a wingspan of no more than 20 inches. So generally, it was going to be a small battery-powered slow-flier. I'm trying to keep the weight under .5 kg so I'm squeezing every gram.
https://www.micromo.com/ might be worth a look ,
some very small DC and stepper motors and the
thin profile range is fascinating. Sadly they do look expensive.
The commercially available micro servo wieghing in at 9 grams
offers the best solution.
