What? a coffee machine? ;) I'd love a lathe and a Bridgeport, too - what I have is a German-made CNC router (720mmx420x110mm work area). Nice toy :) Cutting sheet GF/CF is easy enough, but I gotta stop breaking bits when 3D-cutting aluminium, Delrin, etc. - good cutters are not cheap!

You see! Our approaches are quite different - you use beer, I use coffee (and a CNC machine) ;)

Well certainly they should have experienced and knowledgeable beta testers (like Denny, though I'm sure they couldn't pay him enough). Not sure they need a pompous pedant like me, though ;) - I'm like Taub and Thirteen in "House" - just throw every possible diagnosis on the table in the hope...

I wouldn't touch an Aerodrive for a Red-carrier, personally. Not only are you placing all your eggs in one basket but you're also placing that basket in exactly the wrong place - dead centre in the frame, hidden beneath everything else where it will get little or no airflow. I don't advocate...

Since they're being "loose" with the terminology anyway, it's still likely that their "Velocity Gain" was the I term (or related to it) - having "I" too high would cause an over-nervous system - lowering it would, indeed, dampen the system. It's possible that for the UI they were actually...

Yep - artificially-induced lag is a poor solution - kinda like "curing" a hyper-active child by strapping a weight-belt around their waist ;) If your new wiring harness works out, it should be named the "Rowland Rig" - as in: "Yeah, I've got a Skyjib/Cinestar setup - with the Rowland Rig, of...

I've dug a bit deeper, looking again at the RSGS manual. First off, the instructions for modifying a servo are disturbingly vague about how to do it and how to verify that you've got it right. I suspect that some users will have it wired wrong. What is clear, though, is that two wires is fine...

Mmmm.... interesting thought - if the jitter is varying cyclically (when the system is at rest) then that further indicates an algorithm issue. In a PID-controlled system, a decaying oscillation suggests that the "I" is set too high (relative to the "P"). Does varying the gain in the setup tool...

A modified servo working with a locked pot, yes - but that's not happening here: the RSGS is the servo's pot. No? If that was the case then the spring wouldn't alter the behaviour ;) Two wires should be okay here - the third connection to the built-in pot would be tied to ground and since the...

I'd go "belt & braces" on this: twist the wires, >5 turns through a ferrite and a cap across the +/- connections inside the servo. The suggestion here is that the RSGS is radiating some nasty EMI and the servos are picking it up. I've seen this issue with 7990's - their magnetic encoder is...

All this talk of deadband - correct me if I'm wrong, but "deadband" refers to the servo's centre position only and how much "margin" there is either side of (say) 1520us before the servo tries to move. So if this was a deadband issue, the jitter should only show up at the centre position. If, on...

Nice shopping list :) Wiring will be critical on a big bird like this - at full throttle you'll be pulling around 300amps through the system. What's your plan for wire/connectors?

Ah - I understand now - it's just regular waypoint flying - I got bored in the first minute of that video so cut it ;) Re: aerial filming (as suggested) - I can see this would be useful if it had some particular capabilities: - the ability to record a manual track (in all three dimensions)...

But the problem is "gimbal lock" - with the above gimbal, if you're pointed directly down at the ground your roll axis is now coincident with the pan axis and they both produce the same pan motion. Can they bypass that?

Slobber! Slobber! Something I've noticed: on this gimbal (and many others) the roll axis is inside the pitch axis, so the progression is pan > tilt > roll. The Shotover example above, however, goes pan > roll > tilt. (Discounting the inner axes, of course.) There's a significant difference...

Not sure what that particular feature does exactly but, in general, I agree with you that the geeks who design this stuff are not photographers. I see little evidence that they've even talked to a photographer before finalising their products. "This is the greatest gimbal ever made (but it only...

Mass balancing and two Kenyons ;) I thought I could hear them at the beginning of the video. Good way to develop arm muscles, too!

Oh, yes! Sigh!

All other things being equal, if you raise the ambient temperature by 25ºC then the running temperature of your ESCs/motors will also rise 25ºC. Unfortunately, those "other things" are never equal :) I'd strongly recommend that you model your craft in eCalc. Get it to the point where eCalc's...

Stainless steel ABEC5 bearings for US$1.45 each? Really? :nevreness:
