Maybe you could get in contact with Milan to have him integrate the needed holes in the product from scratch? He seems to be pretty open to modifications on his pedals, the V3 pedals having been modified to fix things based on the feedback he got from his clients.
I don't know what it is. It moves the stick to end forward position and then you have to fight it. When you move the stick back you have to fight with it and when move past center that force decreases. I don't think the real stick behaves this way, it is dangerous.
Yeah, a couple folks have done it, but iirc, no one has posted schematics. The design of the crosswinds themselves lends nicely to conversion to FFB using a single motor
Your VPC pedals mod sound very interesting, could you posts a photo of it please ? I used to have MFG pedals but I changed to the Virpil VPC ones because I find them better for helicopters and they fit on my DOF H6 motion platform better. I actual have both types of VPC pedals, the ones with toe brakes and also the simpler ones without.

That sounds very interesting. When is the kit expected to be available to order? Are you also thinking about such kits for the TM TPR or the VPC ACE, since these are very widely used?
Thanks for the links and info. My apologies for not spotting them before but I'm still blundering around in Discord, even though I've been following a number of specific interest groups on here for a year or so, I'm still not very adept with it.
wonder is someone knows whats going on here, i made some changes to my diy rhino ( new limiters ) and did the callibration and now both motor center are red, any idea what that means ?
Thanks again for the links and nice clear photos. I've read through them and I think I'll have a crack at it myself As I understand it so far, I just need to order a single motor kit with circuit board and then fix the motor vertically behind my VKB pedals. I already use them without the "spider" feet because I mounted the central box unit on a flat plywood plate, which makes it easier to attach to my DOF h6. So if I bought the kit, plus a cutout switch, an adjusting pot, a USB 2.0 B socket, a drive belt, and a motor cog, then I just need to source a printed large gear wheel ? I notice you specified the middle size single stepper motor kit, I guess because it's the best torque rating for pedals ? Is there a waiting list for single motor kits ?
Honestly, the primary reason I went with the 03 vs the 04 motor is that the 04 was backordered when I was ready to order and I don't like waiting. My published as-built design specifies the 03 because the longer motor would not fit without some modification to the design..
The reality is that even the 03 motor is capable of providing more than enough force for my tastes.
Looking at your setup, I think the challenge will be getting the motor mounted in a way such that the output shaft is inline with where the drive gear would attach to the pedal arms.
Thanks for the confirmation. I'll check out the PDF drawings of each motor to see how they'd fit into my theortical layout. I think the advantage of the VKB pedals is when the spider spreaders are removed the main central box is quite small, so I should be able to raise it to the required height to line up the output pulley. Though I will be choosing the shortest motor possible to keep it as low as possible. I also use the H6 with fanatec car pedals, so I'll keep the pedal support plate at the existing height.
That's good to hear , a 12 month wait would seriously cramp my enthusiasm ! I've had DOF rigs for three years now, originally an H3 and now an H6, extensively modified. They are great for car sims, but they have a problem with flight sims. The direct drive motors suffer from "cogging", because of the much more subtle pitch and roll movements. The newer SFU gearboxes greatly improve the smoothness, but the jerking during what should be perfectly smooth angle changes is still an immersion breaker. They use simple 24v DC brush motors, so the default direct drive motors jerk around the commutator segments when making very (very) slow are partial revolutions. There is a DIY solution though. A clever Guy on the Facebook DOF Builders group hit on the idea of swapping the direct drive motors for 4:1 planetary geared motors. So the motor shaft turns 4 times faster for the same degree of SFU "lift". I did the mod on my H6 and it is now beautifully smooth, even when the MsFS or xPlane autoplilot is making barely perceptible movements, (which previously jerked badly). https://youtu.be/qOO9tOMFUSE
Here's a video of my DOF Reality H6 motion platform after being modified with Planetary Geared Motors to eliminate the jerkiness during subtle changes in pitch and roll. This is caused by "cogging", where the motor steps from one commutator segment to the next when making partial revolutions. This spoils the immersion, especially in VR, becaus...
It's quite a controversial subject. I managed to reduce it on my H3 by moving the pushrods to the innermost holes of the SFU operating levers. That reduced slightly the total angular range of pitch and roll, but it also effectively "down-geared" the movement, by altering the lever's pivot distance. When I upgraded to the H6, that mod was no longer practical, because the principle is totally different. Instead of pivoting the seat on a fixed central UJ, the 6 DOF rigs have 6 motors and pushrods, so the rig "flies" by default at mid-height. It therefore juddered with very slow angle changes, because the ball and screw SFUs were lifting and dropping in short "jerks" as the brush motors (not steppers) went from cummutator segment to segment. Most DOF platform users appear to use them for driving sims, and then there's no problem at all, because car movements are mush more abrupt anyway, compared to flight sims. The company vehemently denies the problem, which is unfortunate, because in all other respects they are supplying a marvelous product at a relatively affordable price, and their sales and customer service is very good, despite being based in a war torn country.
I upgraded my P6 with the SFU upgrade (total nightmare) and I still have the violent βjerkingβ motion when at the max throw distance. The rest of the movement is quite smooth, much smoother than prior to the SFU upgrade. I have read about the clogging mods, but have decided to catch my breath before I attempt another mod or update with the rig.
So far the only way I have found to make my H6 cog-free is by changing the motors to the planetary geared ones. It's a fairly straightforward conversion, but does require a certain level of engineering skill to adapt or create the new motor mounting flanges. On the plus side, no electrical or software mods are required if the rig has external position sensors, rather than the newer rotary encoders. It's simply a matter of bolting the new motors in place of the originals and connecting the pos and neg wires. The adapters are needed because the planetary motors have different PCD mounting holes. New ones can be made from sheet metal or adapted from the old pre-SFU worm and roller gearbox flanges with a little bit of turning in a lathe. New flexible couplers are required as well, since the new motors have 12mm diameter shafts instead of the originals 11mm. (Though I did bore mine out instead in a lathe.) Here's a youtube video showing the old and the new motors alongside each other on an H6. If you look at the silver shaft couplers, you can see the direct drive motor cogging when moving very slowly, while the planetary geared motor coupler turns smoothly, because the motor itself is spinning 4 times faster for the same SFU input shaft speed. https://youtu.be/2UgRFU_gGGw
The phenomenon of "cogging" occurs when a brush type DC motor turns very slowly or when giving partial revolutions. The electricity to the windings is connected via carbon brushes that touch a segmented commutator, so that as it rotates it connects to each coil in turn. There are therefore points at which the energy force "jumps" onto the next...
