TM Warthog Grip PCB


Recommended Posts

Hi to all you electronic gurus, I know you are out there (Sokol and Debolestis spring to mind). I have built several joystick using Leo Bodnar’s PCBs ect but currently someone wants me to build a new grip for his TM Warthog. The mechanics of it are no issue but I could do with some help with the PCB. I don’t want to use the existing one as the whole point is to be able to switch from Fast Jest to Warbird by simply unscrewing the grip. I have been searching the forums and it looks like someone has made some boards but I can’t track them down. Any ideas? Getting boards made is not a problem, there are guys I work with that can do that.

"Piece of Cake!"

 

You need a Shift Register board inside you "Warbird" grip - like the one inside Warghog, based on CD4021 chip. So this grip became "PnP" in Warthog base.

 

Debolestis draw PCB - you can order on OSPark, or DIY one - and already tested this boards, see there, well explained:

Typically Mk.I "spade" need 1 button for MG's and 1 for brake lever - if not used axis for brake, although RL Spit brakes seems used more as "on/off" (YT video). And (optional) 1 button for camera.

 

For Mk.V or IX (or latter) one more button in "BBC" trigger for cannons.

I normally use 1 fire button and a 4 way hat on the camera button. Your board is 25mm across, that will fit into the 100mm extension which has an internal diameter of exactly that.

 

The brake needs an axis so unless your magic PCB can handle that they will have to go brakeless!

Warthog base handle only 2 axis, what make difficult use a axis in brake handle, although a Teeensy/PRO Micro board can be fitet inside this 10 cm tube easily to provide a extra axis, but will need run their USB cable external do Warthog pole.

 

But better use a button for brake than make a "brakeless" spade. :)

 

This 3D drawing for example is for use button under brake lever:

In DCSW has little difference in brake with axis or/key button - in this case the brake force is not applied instantly(ON/OFF), but increase at given rate.

I think the guys I am building it for have other axis dedicated to the brake and they fly Cliffs of Dover as well as DCS. Touch a button brake in CLoD on a Spit and you remodel the prop instantly! I can certainly set up a button similar to the one you suggest if they want it. I will ask them. It is an easy mod to make afterwards as well, thanks for the suggestion.

Yes, the guy that use this kind o grip on Warthog already have a brake solution, like fake "toe brakes" for British planes via joy soft.

 

My point is just that is simple fit a button in brake handle and this can be use as button for other function - park brake maybe?. ;)

 

BTW - I always brake with button in CLOD and ending learn save the propeller. :)

And as use T-Rudder, use that "virtual axis brakes" on joy button for brake in DCSW.

Quick update. All the bits arrived from China today so I fired up the soldering iron and got to work. The two boards I need are done and work! The rest is all mechanical so I am back in my comfort zone

 

 

Thanks chaps, will post a photo when done.

Thanks chaps. Verdict on the handbrake has not been decided. I have one I can cast from and clearly there are enough ports to connect the switch to. I need to test these ones (I built two) and I may add the handbrake to one. Also it looks like some of the chaps who want one are after the rocker gun firing switch from the Mk V rather than the Mk I so that may be a higher priority than the hand brake.

How does one use the spade grip? Grab it like a small wheel?

It was fairly standard on all RAF ac from about 1920 until the jet age. It meant you could get both hands on the stick easily if that was required and swapping from right hand to left hand was easier which was particularly useful in the early Spits as you took off right-handed with the left on the throttle and then swapped straightway to left handed so you could pump the undercarriage up with the left. Not sure it was better as no other country adopted it so universally

Most Russian Fighters of WWII use a kind of "Spade" - but more "square".

Latter some 1st line fighters became use a copy of Luftwaffe KG-12/13-B grip, use that extended to Mig-15 and other jets/trainers.

 

BTW - This guy use a kind of Spit stick in games. Articulated in the middle and with "Spade".

MkV

 

So here is Mk2 (or should it be MkV due to the cannon buttons). I have added a brake lever on a Hall Effect switch. Clearly it is a switch on a Wart Hog but would be an axis on a standalone using a Leo B PCB or similar.

The Hat Switches include a push button function so if you include the 45 degree positions on the right hand Hat Switch that adds up to 17 functions!

To be honest, the Hat Switches were the worst problem. Any you can buy cost £40 each at the very least. So I made these. It is an Alps PCB mounted unit (£1.95 ish) set in a resin mould. Pain to set up but once I made the mould and got a run going I can produce a few fairly quickly.

There are now two MK1s in use with friends for the past year and they are going strong. This latest one goes out to a friend today so I will get feedback from him as to useability and how it all works.
