Are GWS Servos trustable? High torques, small cash

I mean they offer huge amounts of torque for such little money (111 oz/in. 10.99), I’ve always wondered if they are a quality company or not. I mean, they are infact a plane company, so I dont see their servos being put under heavy loads.

Would you trust GWS for bipeds? Whats the difference between them and HITEC? I mean, why is HITEC so expensive compared to these guys?

Thanks for the reply. I read that thread quite a bit ago. It doesnt state much bad about GWS but it doesnt state anything on it’s quality either.

I’ve heard on other websites that GWS breaks and others they are good. I’m not sure.

I plan to order the following:

epyaya[dotcom]/product_info.php?cPath=6_278&products_id=294

(metal gear, 1.66 oz, 1.59 x 0.79 x 1.48 in, 117 oz-in @ 6.0V, 0.18 sec / 60 degrees @ 6V, coreless motor)

And I want to buy 10 of them (15 bucks a pop). They seem too cheap to last long. I dont know if they are trustable. Should I buy it? Please help.

Would you rather buy 10 of these for $150 or HITEC, half the torque (and karbonite gears) for 150?

the real qeastion is what do you intend to use them for ,as stated they dont fit ses , and if they break there gone hitek will replace theres,
the tower pro mg 995 are 208oz in on ebay you can get them for cheap but they still wont work well for ses but you can fudge it and make it work
though I would,nt wont to try to build a hex or biped with them but you could use them in a shoulder and such

wait wait, i never said anything about SES.

my main goal is bipeds, custom ones. I dont plan to buy any brackets at all. whats your take on GWS and towerpro now? are they good? i want to buy the tower pro ones they seem awesome but how are they for bipeds?

Since you are going to be custom building the robot, you might first get one of each servo you are considering and test them. I’d think the leg servos have to handle the most weight, so make a test setup with weights and run the servos in parallel continous 24/7 until they start to malfunction. That way you would not have to rely mostly on opinions.
