heli chair with collective and 7-speed usb gearbox


Recommended Posts

Posted

been busy this week and put together my new heli chair, with collective and adjustable tray for the stick.

also i will show a few pics of my rfactor gearbox i made recently.

 

the collective connects via a removable lead to the wires that used to go to the sllider wheel on the usb combatstick 586, check it out.

shifting up/forwards, top cam moves over centre notch to lock into gear

reverse, now the bottom cam moves, this controls neutral position

the gearbox is rock solid and shifts perfectly, tough as,

feels right, wants to go back to neutral, and locks itself into gear,

the collective makes flying a heli so much better.

 

overall i am happy with the chair for now, hope you enjoyed my show and tell, ggg

thanks for the kind words guys

 

leafer:

no i am not the welder, i let my mate do that part,

he does it all day, horses for courses and i can't weld :)

i did all the design and fabrication apart from the welding.

the collective and gearbox were only designed on the go,

neither were meant to be the final product but they both turned pretty sweet.

 

urze:

a bypass is easy, the plug i used can disconnect the original throttle when you plug in the lead to your external device of choice:thumbup:

 

nordic:

definitely going to add a button box of some sort, i have been hunting for pics of the end of the handle but not much luck, i saw it in the new startup video but i want some good pics to reference.

i left some length on the counterweight end of the shaft to eventually allow for the weight of the button box.

 

have been flying heli's in fsx for practice,

its been said before but god help us when its time to fly and fight :D

 

also just like to say a big thumbs up to bob church from CH-products forum for some technical assistance.

all I can say is... WOW..!

 

.. I just love it whenever I see something complex and apparently difficult to make, comes together as simple and clean as this..!:thumbup:

 

My hat goes of for you mate..! Good design, well made and most of all it seems to take the stressload of frantic "gaming"..! I especially like the way you worked out the angles of the bellkranc's for the collective..

"But (504)Brewber said they were'nt friendly.. So I took'em out.!"

cheers triggerhappy69,

 

was unfamiliar with the terminology of bellcrank but google tells me you mean the connecting rod or conrod/crankshaft as i call it, connecting the shaft to the pot, notice i used a volume knob, as i needed something with the same spline as the pot :)

 

yes its simple and solid, built to take a pounding and constant abuse :thumbup:

the 7-speed gearbox is the same, would love to see someone slam a g-25 like i do mine, they would be picking up the pieces and wiping the tears :D

(nice wheel, shifter could have been better imho)

also the satisfaction of creating your own peripherals is something.

 

i basically just held the shaft in the half up/down position and made a rod line up with the centre of the crank arm, then worked out how far i need to mount it back from the collectives shaft pivot point to get the desired travel, and it worked out approx 100 degrees.

admittedly the first dummy shaft had a few extra holes in it:music_whistling:
