Goblin Skid Clamp Mounting and Tech Notes
Before you mount the Skid Clamps for your Goblin (or Lynx Ultra skids) have a look at the information below. You’ll get better performance from your Skid Clamps — and a better result all round.


Goblin Skid Clamp Sizes and Markings
Each of the three models is designed for a nominal CF skid height (shown in orange). The underside of the latch is marked with the second digit of the nominal skid height it is designed to fit.

The SAB Goblin CF skids vary slightly in thickness and height. The flex in the Skid Clamp latch and base will accommodate slight variations in height (<0.5mm) and the self-adhesive grip discs (included in each pair of Clamps) can be used to 'shim' the Clamp for a tighter grip.

SAB Goblin CF Skid Geometry
Broadly, there are two styles of CF skids in the SAB Goblin range: Standard and Low-Profile. The Low-Profile skids make the heli sit lower at the nose. In doing that, the skids have a 'Toe-In' meaning they are closer together at the front of the heli than at the rear. It’s important to note which style you’re using because the optimum mounting layout of the Skid Clamps will be slightly different.

Standard Skids Low Profile and Competition Skids ('Toe-In')
Goblin Standard skids are parallel and the heli sits more or less level. (SAB Goblin Low-Profile skids [P/N H0107-S are shown above.) Goblin Low Profile and Competition skids (as well as several Lynx Ultra skids) are not parallel. The footprint is narrower at the nose. This is 'Toe-In.' The heli sits lower at the nose. (SAB Goblin Low-Profile skids [P/N H0106-S] are shown above.)


Mounting Layouts for Standard and 'Toe-In' CF Skids

In order for the CF skid to fit snugly against the ramp feature of the Skid Clamp base, the Skid Clamps should be mounted square to the CF skid . For Standard skids the Clamps will be in line with each other and form a rectangle. But for the low profile and competition CF skids, the Clamps should be mounted with the inboard mounting screw offset toward the tail of the heli. In all cases, the object is to mount the Skid Clamp square with the CF skid.
