P1KW Posted April 18, 2014 Share Posted April 18, 2014 (edited) Hi guys. A little update of my previous work, with some improvements. -The tube is now shorter. -The grip is aligned by hand. -The dust cover on the base is more solid and durable than the original. The new dust cover helps eliminate slack stick. Based on an idea of Pegaso "The Sponge MOD", :smartass: from Squadron "Cruz de San Andres." Later I will add more information. If other people have documented, other methods or other materials, I propose to share links to facilitate locating information. Links: G940 Old Inf MEASURES SETTINGS Program control by Average_Pilot, from ED forums. Thank you, without their work this mod would not be possible..:thumbup: Damper and friction effects in force feedback Note: simFFB is essential to properly simulate a "ForceTrim" control. Like this video; Edit: This is the main part. Aluminum tube, curved at the factory. -Diameter: 16 mm -Wall thickness: 2 mm This is the dust cover still without cutting. You can spare four lower rings. It is more solid and stronger than the original, but as I said its function is to reduce the slack zone around the center. The dust cover already cut; The method for joining the grip to the tube. Just need a through bolt. Marked with blue dot.; Greetings!

Scarecrow Posted April 19, 2014 Share Posted April 19, 2014 I've been thinking about an extension and center mounting for my G940. So now I have to ask a stupid question:blush: What is the function of the curve in the cyclic stick? Link to comment Share on other sites More sharing options...
P1KW Posted April 19, 2014 Author Share Posted April 19, 2014 Circumventing seat base. Is also purely decorative and immersive as it is very common in helicopters.

Scarecrow Posted April 21, 2014 Share Posted April 21, 2014 Very cool. Could you explain the sponge mod? Link to comment Share on other sites More sharing options...
P1KW Posted April 21, 2014 Author Share Posted April 21, 2014 Very cool. Could you explain the sponge mod? Basically it is an idea of a squad mate. Consists of a small sponge in place in the base to mitigate joy slack. Here is the original post, sorry, in Spanish. http://www.cruzdesanandres.com/foroviejo/viewtopic.php?f=17&t=9135 Greetings!

P1KW Posted May 3, 2014 Author Share Posted May 3, 2014 An update with the measurements, and some image more in the first thread. The first version is that shown in the video. The second capture is a shorter version, I think is the ideal size. Greetings! "If adventure is dangerous, try the routine. It is deadly." Paulo Coelho.

P1KW Posted May 7, 2014 Author Share Posted May 7, 2014 (edited) These adjustments leave a central area very progressive. It may be good for a rookie, briefly. Or for those who come from FIXED WING. With an extended joysctick, as realistic, not using curl, or very little. The purpose of these adjustments is to release the hand after trimmer without the helicopter significantly change their attitude. With the change of distance between magnet / Hall Sensor I explain in the following thread, you can keep a curve <5% and change the value "Sensitivity" in the Logitech software. (Between 40/60%) Now comes the hard part. Explain adjustments and reason. These adjustments are based on the control of the FFB, which provides program AveragePilot. Without this program is not viable to simulate a ForceTrim device. Damper and friction effects in force feedback There are several factors to keep in mind about the G940. 1 - The grip is designed for a certain length on the lever. Increase the length increases movement in the grip more than desirable. 2 - The G940 has a mushy zone in the center. 3 - The G940 has an external area outside values, and also beyond the control of the FFB motors. I mean, you can physically get to that area, even a useless area. I marked the three zones in the previous image. The blue area corresponds to the spongy zone of G940, and I tried to coincide with the "area curve" in the simulator. The objective is that the movement in this area have little impact on the simulator. The green area is the major useful area is where the G940 should work most of the time. In the above image, the saturation adjustment cut out to 90%, is to limit the total travel of the grip. As I said extending the lever increases the grip travel beyond desirable. The red area is in the outer limits of G940, no values, no force FFB. I will focus my explanation based on two simulators, DCSW and X-Plane X, since it is a modification designed for helicopters, and beyond these simulators do not have anything that is minimally realistic. Basically you have two tools to adjust your G940 . The first is the sensitivity adjustment or progressivity in the G940 software. This setting is important because it also affects the resolution of the actuator FFB, especially around the spongy zone. The default is 50%. You can adjust between 40-60%. Smaller values will give less accurate anchorage of FFB, and conversely higher values. The following screenshots show strength and sensitivity settings. The force is oversized, because the extension of the lever. The second is the adjustment of the sensitivity curve in the simulator. The purpose of this adjustment is to leave inoperative, the spongy zone of the joystick. I mean, that movement of the joystick in the spongy zone has the least possible impact on the simulator. My settings are between 15-20%. X-Plane yaw axe are ok betwen 50%, not like image: DCSW: The ultimate goal is to release the hands of your grip without the helicopter loses his attitude.

P1KW Posted June 11, 2014 Author Share Posted June 11, 2014 (edited) Well, another advance. Reduce the spongy area in the center of the stick, I have to get this reduced the distancing between the magnet stick, and Hall sensor. This overrides the settings of the previous post, the sensitivity curve can be left at 0%, and can release the hand after the helicopter trimmer without losing its attitude. You have to practically disassemble the entire joystick, but it is not an overly complicated operation. I lost my images ImageShack, so I can not document graphically as disassemble the Grip. Basically you have to remove 6 screws and gently pry the two tabs at the base of the grip. You will need to disconnect the 3-wire cable that goes from the base. Once removed, the Grip, and open the base of the joystick you will see something like this: The magnet is in the lower part of the lever. To get there, first remove the plastic cover that holds the engine, remove the 5 screws. Carefully remove the cover without pulling any part of the wiring. Now comes the tricky part. We must dislodge engines, and turn to that seen longuitudinal in the attached image. The easy part is to remove the magnet and insert two washers. ;) Just need refitting all, with special attention to the wiring and the position of the engines. Greetings!

Mtnbiker1998 Posted October 26, 2017 Share Posted October 26, 2017 Wow, this is a really impressive mod. How is the ffb strength with that much of an extension? I've heard the msffb2 gets rather weak with extensions. I'm almost tempted to pick up a G940 after reading through this!
