 Super Skids 400 Black

SuperSkids400™ are just what you need for your 400 to 450 size helicopter.
The built-in passive suspension is designed to isolate your helicopter's frame from impact forces. 
Fits Esky HoneyBee King2, Belt CP,Big Lama, Axe CP, E-flite Blade 400,Walkera DF36 and similar 400 size helis,
T-rex and similar 450 helis, and some 300 size helicopters.
Fits the Esky HoneyBee FP V2 & CP3, and the Exceed Falcon 40 V2 (requires Adapter22 for the F40 V2).

 SuperSkids400 landing gear is engineered to be flexible enough so it won't break,
but also to absorb impact so it's not transferred to the rest of your helicopter.
The unique upright design of the legs (sometimes referred to as "alligator legs")
helps to stop the landing gear from spreading apart on impact and letting your helicopter 'bottom out'.
The top of the landing gear is designed to operate like a leaf spring on a car,
giving your heli a suspension. On heavy models, it's desired to have an upward camber (or crown) on the top of the landing gear.

Using a crown suspension is not new to SuperSkids, but it's interesting to see that some r/c heli manufacturers now seem to be using it. If you have a HBK2 or Belt CP, you may have noticed that your stock landing gear holes don't line up with the holes in the frame. When you install the screws, the landing gear crowns upward. This helps their landing gear to hold it's shape, but unfortunately, the spread out angle of their landing gear legs sends any shock right to the frame with no suspension effect.

Nylon wire ties are included with your kit. For heavy helicopters, one or two can be wrapped around the top of the rear landing gear and your helicopter frame to help support the crown as shown on this Belt CP.
