FW 190 KG13 grip project

[Extranajero]

Hola Amigos, this is my KG13 stick project, for the FW-190

 

 

[Extranajero]

I'm overwhelmed by the interest in my project :D

[agrasyuk]

grip looks awesome, but me at least I'm waiting for some more details, like what will you attach this to, what else you have built and planned for your pit.

[Schweppes]

Very interesting! I have been thinking about making one myself. Did you make the grip by yourself or did you buy it?

[Godzila]

From what material is the grip made of?

[Extranajero]

I made everything from scratch apart from the switch internals. The grip started out as two pieces of MDF carved to shape and then covered in epoxy putty. The trigger was hacked out of a piece of aluminium, the cannon button I turned on the lathe.

I am building my own joystick base for it.

 

This is the bomb release pushbutton which mounts to the side of the grip. I made the housing from copper sheet bent and hammered around an aluminium former I turned with the lathe. Took 3 days :D

 

[Godzila]

Nicely done. I don't know if you tried force feedback, but you should try MS FFB2 once. In my opinion it is a must for old planes, since it gives you feedback about too high AoA. I would put that grip on extended MSFFB2 base. Since you have an access to lathe you can mod MSFFB2's gimbals to make them without wobble and play. That combined would make very quality peace of hardware.

 

Just an idea, not everyone likes FFB. I couldn't go back to spring joystick once I tried MSFFB2.

[Extranajero]

I have thought about FFB, but for now my design intent is to keep things simple.

I did design the gimbals to be easily adaptable to mount things like FFB motors, rotary dampers etc.

I haven't used an FFB joystick before but I have flown light aircraft including practicing stalls and spins and I agree completely that spring centering isn't very realistic.

It is cheap and easy though ;)

Nice grip.

 

I will like to see more pic of the progress and how u cut the mdf to the the grip shape

[Extranajero]

how u cut the mdf to the the grip shape

 

I didn't take any photos of that stage, sorry. I can try to explain though.

 

I used two pieces of mdf screwed together and cut the side profile of the grip with a jigsaw. I used a drawing from here - http://www.ww2aircraft.net/forum/technical-requests/kg13-dimensions-21987.html to make a template.

Then I shaped the grip with a belt sander, files and a Dremel tool.

After that I drilled the holes for the two pushbuttons ( the top one is difficult, it is at an angle ) and separated the two halves so I could hollow out the inside for the wiring. Then I glued them back together.

 

The shape of the grip where the trigger mounts is thicker than it should be, I was worried about the strength of the mdf if I made it exactly to scale.

 

After that I used home made epoxy putty to smooth the surface of the grip and glued mesh flyscreen material to it to make the checkered area.

 

Edit - got the bomb release button trial fitted. Still need to make the pins which hold it in place look like the original screws.

i'm not sure i can make it but nice to see your progress

It wasn't easy. There are resin replica grips available, some I have seen are awful but others look great. I think you could convert one of those.

 

But what about an IAF Spitfire grip instead ? :smilewink: that would be very cool

[assafm25]

can u send me links for some rasin grips in normal price?

200$ for one is expensive

 

i will make it israeli spit :)

 

for now i need 3

P-51

UH-1D + Collective

Mig-21

The most affordable KG grip resin replica is this 1:1 plastic model:

 

http://www.hyperscale.com/2009/reviews/kits/tailboombf109stickbg_1.htm

 

Cost around 70 Euros from a guy in Italy, that made too a 1:1 AH 2040 kit.

 

But the resing used and some wall dimensions dont make then suitable to use as joystick, but you can use this as model to replicate in more solid resin, do the trigger in metal...

BTW - Extranajero, nice work. :thumbup:

I am also thinking how to made/buy Kg-13. What about this kg-13. My original plan was to buy KG-13 from Tail Boom and strength it with internal epoxy/glass fiber lamination, do you think it is possible. Have anyone experience with part from simparts.de,???

Nice scratch built!

 

Thanks, your KG13 build was an inspiration to me ;)

[VO101_MMaister]

I am glad you find it useful. By the way it is always the most rewarding to use something what we built/created ourself! You have the trigger and the button clip, so you are over the most challenging part!:)

I already feel like I have built the whole aircraft, not just half a control grip :D

 

I did not mention that the budget I have set myself for this project is 0 Euro's - everything has to be made from materials I already have in my workshop.

I am only allowed to buy epoxy putty, glue and paint.

The next update will be the lower half of the grip, I guess I will have to make the box for the wiring connectors from copper sheet.

I buy one these (Tail Boom) kits, and find really fragile for other purpose that not display.

The grip are not bored, which is needed to run wires for trigger, buttons.

The lateral parts that hold trigger probable will broke if you add a metal trigger...

The "tube" bellow grip is thin, maybe if you place a PVC or aluminium tube inside work as reinforcement.

 

I conclude that the kit worth as a template to ones that want a joystick make one using appropriated resin.

 

This one from Simparts has been usede as joystick be a guy in SimHQ.

Notice in the last picture that the mold has a defect, a vertical line, will need some work to correct this. And is not include trigger, button caps...

I agree 100%

 

I think boring a hole for the wiring would be a very, very difficult task on a solid grip. Just drilling a hole is easy if you have a drilling machine and a long drill, but to hold the grip at the correct angle on the machine would require making a special purpose jig.

The 'ears' ( just my name for them ) which hold the trigger axis pin I think are a very weak point if the grip is resin.

Thanks for opinion/advice so it look too me there is currently no suitable KG-13 grip for joystick on the market. I don't know if Baurs grip is still available, but right now is 250€ for me too much, so maybe later:pilotfly:….

[Extranajero]

I think the 75 EU Simparts casting is suitable but it looks like it will need a lot of filler to correct the poor surface.

But then you need four buttons at 50 EU each - the button clip is available from a company that makes parts for real warbirds, that is 37 EU

I can't think of a cheap way to build a KG13 unless you can make parts yourself :(

That one from Bauer is done in resign, so the idea of use Tail Boom model as plug is suitable. You need do a negative mold in silicone and cast the new in high resistant resign... I think that cost in material will be hight...

 

VKB (Russia) are working in a KG-12 metal grip for his Mamba joysticks - will be sold as upgrade - but the estimated price is around 250/300$.

Don't see more information about, but this KG-13B grip is in resin, adapted to be "joystick". :joystick:

"B Knopf" looks a mini-stick. Need a paint job. :)
