  1. Thanks! The handle is my own design :) I cut it from 8mm aluminium with a scroll saw.
  2. Of course! How could I forget! :) Thanks! Calibrating was easy. Just like any other controller. The loadcell is quite sensitive, so when moving the joystick around, the inertia of the mass of the handle registers...and the handle is made from aluminium..! It's minor, but I dialed in a a little deadzone to get rid of it. I don't know why the thumbnails are rotated, and the pics squashed when enlarging... Makes it look even chunkier ;)
  3. I just wanted to share my latest controller. I have wanted a stick mounted handbrake lever since the MiG-15 was released. The release of the L-39C made my wish even stronger. The Spitfire finally made it impossible to live without it... I sourced an aluminium electronics box and a loadcell from ebay and got the BU836-LC controller from leobodnar.com. Here's the result. Yes, it's quite a big chunk of hardware to mount onto the stick. The mount itself is a temporary fix. I have ordered a airgun scope attachment that I think will do the job. So far I have tried it with the L-39C and the Spitfire, and groundhandling has improved greatly with a proportional brake controller. The Spitfire still requires skill in takeoffs, but taxiing has improved significantly!
  4. Really cool mod! I like rotary encoders as well. They are great for trims and other +/- controls that have button input.
  5. I mounted my TIR sensor behind me. Worked great. Just mount the track clip facing backwards, on the other side of your headset. Then you just reverse the axes that moves the wrong way.
  6. :megalol: One can never know for sure... ;) Here's my pit. It's not bad, and with VR I don't see much of it anyway. But I sure would like to build a "real" pit with working gauges and triple screens or projectors... :pilotfly:
  7. Nah, let's not... You do remember what happened to Tengil, right? ;) I'm busy working on a Radar stick for the Viggen, so I can wait for updates. Looks good so far though... :)
  8. Oh! Ok :) Really? I didn't know that. I don't think the Spitfire lever works that way though. EDIT: Looking at that movie... Didn't see your link at first. @10:05 you can see the pilot using the brake handle, ever so slightly. Just nudging it, really. He's nowhere near full travel on that handle, which tells me he's just tapping the brakes, so to speak. So, it seems like it's a proportional input, but the pilot is not braking hard. EDIT 2: I found this text by Jeff Ethell: This suggests that brake application was proportional to the input from the hand lever. On the other hand, when simulating flight on a stationary PC, you miss many physical inputs that real flying would give you. Sense of decelleration when braking, for instance. You don't get that in the sim, so you need to be able to control your braking with higher precision than you would in real life. This is the same with the joystick. No aircraft I have ever flown has flighcontrols that are as precise as my old VKB stick or the new BRD stick. So, using an proportional axis to control brakes may be a better way of simulating braking, even if it's not technically correct. I have used the Warthog paddle switch for braking in the L-39C and it works. Right now I'm working on a handbrake lever, using a bodnar board and a loadcell. Here's a vid of my "proof of concept" ;)
  9. LOL! My pit is in the spare bedroom as well. But it can be stowed away and converted to a bench... ;)
  10. I have a Viggen to play with... As long as that doesn't change, I'm happy! ;)
  11. Yes, since the TM Warthog didn't have an analogue lever on the grip. :) You lost me..? What do you mean?
  12. You buy early access you're part of the testing and contribute towards finding and fixing the bugs. Why else buy early access, unfinished, software..? Did anybody buy the Viggen and thought it would work perfectly from day one? :)
  13. Here's the dimensions I got from Baur. Note the two values of the width are dependent of the angle of the foot plates.
  14. It should be, since the Mongoos grip is compatible with the WH base... The Analogue brake lever won't work though. But maybe that's something BRD can fix?
  15. The workmanship displayed in this thread is incredible..! I just love it! Many simple but brilliant solutions. Good job! I wish I had space for a cockpit of this size... :)
  16. It's awesome! Which grip will you use with it?
  17. Congratulations on a great stick! I got the BRD-N Black Stork, and it's fantastic! I wrote a review of it over at Mudspike.com, if interested.
  18. Well, moving your head in VR means you have to move it at a 1:1 scale. I.e. you have to move your head as much as you would in real life. With TrackIR this is scaleable. You would be able to crane your virtual neck effortlessly to look straight back and out the canopy, just by turning your head a few degrees. This isn't as easy in VR. You need to move quite far to actually be able to stick your head out of the virtual canopy. Especially if you're sitting down at your HOTAS :) Believe me, checking six in VR is much harder than with TrackIR! Same with putting your head through the canopy.
  19. Ah! Yes, I do... No mystery then. Thanks! :)
  20. The Viggen works fine for me, in DCS2. I noticed, however, that I was never asked to enter the serial for the Viggen or the Spitfire modules, when I installed them...
  21. Software development in a nutshell..! ;) You'll find a fix.
  22. This is a core problem with virtual reality. Mixing virtual and physical boundaries... If your virtual head is obstructed, but your physical head is not, it will confuse your brain to the point that it can induce motion sickness.
  23. Whoa..! Old thread resurrection! :) Yes, it's a VKB Black Mamba with the Warthog grip...

    Wind

    An aircraft, or a wing, stalls at a certain angle of attack. AoA is the angle between the relative airflow and the chord of the wing. An aircraft can stall at any airspeed. However, the AoA at 1G, where lift equals weight, you find the Vs1, or Stall speed at 1G. In theory, this stall speed is only dependent of the relative airflow. It doesn't matter if the aircraft is travelling at this speed in still air, a huge fan is blowing the wind at the aircraft or the airmass is moving. It's the wind speed that meets the wing that is important. So, if your stall speed is 100 kt, and you're facing a 20 kt headwind, the indicated airspeed (IAS, the speed relative the air) will be 100 kt, but the ground speed (speed in relation to the ground) will be 80 kt. Wind does not affect the IAS stall speed. But, it's good airmanship to allow for shifting winds and gusts, so you should add speed so that the aircraft won't stall because the heavy aircraft won't change it's momentum as fast as the light air will.
