I starting my hexapod project and have issue on buget. For save cost on body kit I made body part from plastict sheet cut with jigsaw (inspire by phoenix kit). Then I want to reduce cost of servo so I try “Tower Pro” this brand from china. I can find lowest price for micro servo about 6.5 $ for Tower Pro SG91R or SG92. This two model have Stall torque at 1.8kg for 5v. only (not accept 6v.). This price for local thailand shop (I live in thailand). But for my project I choose Tower Pro SG5010 Stall torque 5.5kg/cm(4.8V) (6.5kg for 6V.). This is better than Futaba S3001 and price only 10.8 $ (i order 18 item so i get discount at 10%). Just see my video you will see Stall torque 6.5Kg is enough to make it walk.
For progarming source code I use phoenix code 2.0 on BAP28 + BBII + SSC32
A most interesting project. Do you have patterns for the leg and body parts? Somebody else made a similar hexapod using thin wood for the leg and body parts, which may help keep cost down. I’ve got several of the below servos which may be the same as yours.
Wow. It same as i use in my project but cheaper than retailer in thailand.
body design layout as your request is in attachment. I use coralDraw 9 as 2D design application because I prefer this than adobe .AI format and I can’t use CAD application.

I don’t have coreldraw at home to open the drawings, so I’ll have to see if a computer at work has it. If the drawings can be put in an actual size PDF document, then the part could be directly traced on to a sheet of thin plywood for cutting out. A sheet of 5.2mm X 24" X 24" plywood is only ~$3 in the US. Sheets of 1/8" “door facing” plywood are also available. Below is a wood based hexapod.
