My Yak is still in the box, not sure how much bigger the surface is; Venus is not small, but not 3D.
The author of the report talked about comparing the electrical load of the servo during flight to a static load on a bench - that's where I got the 21 oz-in (converted from 1.5 kg-cm):
...400[mA] is the consumption with a static load of 1.5[kgcm] applied to the servo.
and he measured 200-250ma draw for stall turn.
I don't mean to be doubting the masses, but the report does have me thinking. Even if the load was 4 times what he tested, it still would be under the 88oz-in of a DS821.
Last thing is I have a hard time wrapping my head around the 'more power to hold the servo' idea. Everything I've been learning in school for the past 3 years talks about forces being greater during acceleration. I haven't taken electrical classes yet but I'm not sure if it's an electrical thing. For the barn door example, I think it would be easier to hold the barn door steady than to try to move it against a heavy wind. If it wasn't finals week I'd definitely be drawing a good FBD right now
Does anyone have any experience with servos failing under load simply due to too high of a load?
