Need tall landing gear soulution for triax and joker 2.
I have a triax camera mount on my brand new joker 2 that flew fine until i put the triax camera mount on it. Now i got CRAZY shaking of the heli since i put it on, I am terrified to fly it.

I am not saying its the camera mount i DO NOT think it is, and it appears to be a fine mount by the way. I think (not sure) its the tall landing gear i had to use from a large rc plane to make the joker sit high enough to support this camera mount. The triax does not come with landing gear for the joker and apparently not the support for it either to date, since i got no email response from triax on this. Does anyone have a suggestion for tall landing gear homemade or bought? joker needs to sit about 9 inches of the floor. thanks men..

all opinions on this welcome.. here is a pain pic, dam old fashioned website so hard to post pics or do anything

I usually bend alum tubing and make my own landing gear, super cheap and easy.

I bend it at home, just pack some sand in the tubing and bend it.

You could try the AP landing gear from minicopter.

AP landing gear

Full carbon set to built a basic landing gear for adapting a camera holder and a stabilization or steering system for the camera. The platform allows to mount the central camera axis and to contain the electronic equipment or additional flight batteries. The landing gear can additional be stiffened with one or two horizontal carbon bars with clamps to avoid the streching of the gear during hard landings.
Technical datas:
Weight 580 grams (as shown in the pic)
Width at the skids: 390 mm
Width at the platform: 190 mm
Length of skids: 400 mm
Length of platform: 235 mm
Height over all: 300 mm
Height from ground to platform:235 mm

Ord.-no. 850 Camera landing gear
Ord.-no. 855 Additional stiffener for horizontal skid connection
shop-link: http://www.shop.minicopter.de/shop_en/index1.asp?r=85

quite pricey however, about 350 USD

^^ per the post above - please talk to Nooobs about his experience with this setup. It also will have issues with vibration if not laterally braced. I would suggest using a fabricated tube or bent right-angle aluminum. If the gear is allowed to flex side to side, the helicopter will shake like mad. I tried several iterations until I settled on one that I built/tig welded out of aluminum with partially boxed legs. I tried it without the boxed legs and the machine attempted self-sabotage nearly every time.

With regards to the shaking: did you put weight on the mount? The dampers are usually tuned to hold a specific weight. The mount might start to resonate when you fly it unloaded...

DTM - a certain amount of vibration is expected and occurs at any weight in the mount. I've seen it happen with it empty, a HC-7 OR a 5D mk2 w/ 17-40L lens on it. Big weight differences there, and of course every machine has it's own resonance points. I still recommend as close to the stiffest gear as you can make/buy.

My AP landing-gear from minicopter, works great in the air. But when standing on the ground and the rpm passes a certain point, there is a shake.

On which surface did You try to run up ? Your system seems to suffer from ground resonance ... If it was concrete or a similar surface then better move to lawn or something equivalent ... the surface has to be inhomogenic ... And add weight to the dampers ... They seem to be too loose ...

cranester, can you post a pic of your gear? maybe i can pay you to make me one, if you wanted to?

The joker gear is 250E, thats like what $300?? Wow thats alot. I bet it takes like 6 weeks to get a set too. I'll skip that one for the point of it, but it does look nice and well made.
