@walmis Maybe we need a DIY Projects channel so people like me don't muddy up the General channel showing off their science projects 
Jin the meantime you could make a new post in #

PQuestion, I got on the waitlist twice. Will my first submission count for my spot in line?
WFYI Rhino has 12T pulleys
TI appreciate your concern, however, the pulley can turn 70° either way, before the screw becomes the bearing part of the belt. It will only turn 20° so worst case, 13 belt cogs will be sharing the load with the screw. The screw (and washer) is basically just pulling the belt down to the pulley. It won’t be seeing much of the belt tension. But, as always, if it doesn’t work I’ll just redesign. 
SI am really interested for this project. I am fallowing
SI will suggest to put the motor inside the base under the metal tube to save some space

NSure enough it does... I have my shrouds covering mine up and was too lazy to remove them so I was looking at pictures from the photo spread on imgur, which looks like it had 20T gears on it
WYeah, the first few rhinos had slightly larger pulleys
A105 made it home 
ANow to rebuild the whole rig to accommodate it 
JMan those things are flying off the shelves now!
Bdon't jinx it, lol
SYou can also add loadcell which would allow for way smooth resistance or damping effects
SLike the simucube pedals
NHow so? I'm not familiar with the pedals (or much of anything sim-racing related), but my understanding of what a load cell does, doesn't seem to have an application here. But I'd be happy to glue one in there somewhere if it meant I could charge $2200 for a collective 
... I thought flight sims were expensive 
FWIW, the dampening/friction effects on the Rhino are pretty damn good.

SI haven't played with this personally yet but I imagine that the loadcell would provide a lot more accurate motor load sensing. You would figure out a formula for the relation between the motor amperage and loadcell output weight then just use the loadcell output for regular use and and a hall sensor for motor protection or calibration
SI think the benefits of using a motor on a collective are minimal and the extra cost doesn't justify it
SThis is the collective I designed. There are several build videos of the base unit assembly. I will do some videos of the heads in the coming weeks.
I'm using Teensy 2.0 boards because they are small and easy to personalize with your own PID/VID combo, as well as name it. I will do a vid of the programming procedure and provide the modded librar...

Sa collective like this that has a spring to hold the head up and a bit of resistance does the same thing at no extra cost
Sthe benefit from adding a motor would be much greater on a pedal set or joystick that can have multiple uses like simulating the rudder or stick of a helicopter vs a ww2 plane vs a plane that uses force sensing or creating your own spring profiles etc
NAny helicopter enthusiast would disagree vehemently that "a spring and some resistance" makes for a suitable collective.
Is a FFB collective going to make me a better sim heli-pilot? No, absolutely not. Is it going to be fk'n cool? Yes.. yes it is.

Sbecause if I could just buy one rudder set for example that can do everything that would save me a lot of money or time if I like to fly different stuff
SOk well I just cant think of any benefits it would have over a mechanical spring and resistance collective
Slike I would only use my collective for only flying helicopters and its easy enough to make a mechanical system that works really well just for that specific purpose
Swhile a joystick I need it for everything like flyng my helciopter,plane spacship etc
Slike I'm not tryng to be mean or anything im just sayng what I think as a sim enthusiast
NI mean.. I'm not going to try to convince you that you need a FFB collective. By that same logic, a throttle quadrant serves fine as a collective too. Many people who don't focus on heli's do so.. and thats fine.
Sa throttle quadrant isnt the best as a collective because it has no spring so you have to use a really high resistance to keep the collective head up which doesn't feel very nice and can have stiction
Sif you could add a spring to the throttle quadrant whenever you want to use it as a collective then that would work
Nyou lost me with the spring.... a collective stays where you move it
Syeah but normally it wants to fall down because of gravity
Sso you etheir have to use lots of resistance to keep it from falling or add a spring to equalize the weight and then a bit of resistance for feel
Swhen you just use resistance then when your pulling it up you can feel more resistance then when your pushing it down which feels weird
Nthats why people make counterbalanced designs. Hydraulic dampening is superior to friction as well. My current (DIY) collective is counterbalanced and uses a rotary damper to provide dampening. Its a 3D printed monstrosity, but it performs better than anything you'd get from Virpil or elsewhere.
This 'FFB' design I am working on will be far superior to my current in-use design.

Sthe spring does the same function as counter balance
NIts totally fine if you don't see the point. It doesn't hurt my feelings. It won't hurt my feelings if nobody ever makes one either. The design will be made available regardless...
Swell if you could tell me the point then maybe I would see it lol
Slike why is the ffb design superior to counter balance
Sim curious to know
Sso you can use a torsion spring like this
Sthe only diference between a spring and counter balance is that you can fly upside down with the counter balance irl and the stick would stay where it is while with a spring it would fall
