With the Big Scale-EXTREME an adjustable clutch for very special requirements has been designed:For large-displacement enginesFor heavy or high traction cars (Losi, HPI)For modified performance enginesFor the demanding off-road useRapid wear of a clutch is a sign of constant slipping, even beyond engagement speed. In this case, the clutch does not transfer the applied torque.This is where the Big ScaleEXTREME sets a new standard.The new design of the "Extreme" prevents the centrifugal forces of clutch springs or lever side of the clutch shoes from counteracting the centrifugal force of the friction pad side even after engagement.As a result this clutch can transfer lots of power with minimal wear.The new design ensures that the centrifugal forces are transferred in full to the clutch lining. Precise engagement and disengagement even under high loads and inside of closed clutch bell carriers means no problem for this clutch.The clutch can be easily adjusted to the engagement speed through three set screws without clutch bell removal, so you can match the characteristics of your engine.The special clutch lining of the Big Scale-EXTREME is particularly wear-resistant and - especially in combination with a high-quality nitrited clutch bell (), guarantees for an exceptionally long service life! Contrary to the "Cross" or "Race" version there's no need to uninstall the clutch from the engine for maintenance. All parts are easily accessible from the front after removing the front plate.Please see the specifications tab for further information and handling advices!The regular price of the Big Scale-EXTREME is EUR 139.90
Gas-nitrited tuning clutch bell machined from high grade steel with a hole for easy clutch adjustment. Special vents remove dirt and clutch lining debris automatically, preventing it from accumulating in the clutch bell and causing premature wear to clutch bell and linings. They aid in cooling of the clutch bell as well.The clutch bell features a significantly reinforced wearing surface whichguarantees dimensional stability even under high loads!Since this clutch bell is single-piece machined from bar stock there is no weld bead on the inside of the face plate. The gained space allows now to use the adjustable GPM clutches Big Scale Extreme and Cross.Suitable for slot drive HPI Baja pinions, both stock using a 4mm bolt and aftermarket ones for 5mm bolts. Comes with M4 and M5 bolts included.

The Gas-nitrited tuning clutch bell:Gas-nitrited tuning clutch bell machined from high grade steel with a hole for easy clutch adjustment. Special vents remove dirt and clutch lining debris automatically, preventing it from accumulating in the clutch bell and causing premature wear to clutch bell and linings. They aid in cooling of the clutch bell as well. The clutch bell features a significantly reinforced wearing surface and face which guarantees dimensional stability even under high loads! The shaft is a tiny bit longer than stock (about 0.2 mm) to prevent the bearings from binding. Since this clutch bell is single-piece machined from bar stock there is no weld bead on the inside of the face plate. The gained space allows now to use the adjustable GPM Big Scale-Cross clutch. Suitable for genuine slot drive HPI pinions. Comes with bolts and spring washers included.The GPM-Big Scale clutch:Suitable for racing and for the ambitious hobbyist driver. Unlike the stock clutch, the installed GPM-Big Scale clutch can be adjusted by turning one single screw. A 2.5 mm allen key wrench is required for this application.Therefore it is possible to precisely adjust the clutch engagement depending on track characteristics.Handling instructions for three-shoe clutches y0730 GPM Big Scale Cross and y0731 GPM Big Scale RaceInstallation:The GPM Big Scale clutch will be bolted to the crankshaft using the supplied CSH-screw.It should be noted that the use of thread locking compound on that screw is neither necessary nor recommended!Removal:Remove the CSH-screw with a 4mm Allen wrench; then insert a suitable M8 bolt and remove the clutch from the crankcase cone by tightening that bolt. Hole for adjustment:For clutch adjustment without removing the clutch bell a 4 4.5 mm hole must be drilled into the clutch bell for access to the adjustment screw. Placement of the hole depends on clutch bell dimensions and car; so you have to make your own measurements for the placement of the hole.It is important that the drilled hole is thoroughly deburred (at least on the inside of the clutch bell) to prevent excessive clutch pad wear. Breaking in:A new clutch or shoes fitted with new pad should always be broken in. Therefore the clutch engagement speed should not be too high for the first tank of fuel. This gives the lining the possibility to adjust to the clutch bell without glazing. The only difference between two clutches is the clutch spring rate, which provides the optimal range for clutch engagement depending on the application. The three available versions of clutch springs provide adjustability within the following RPM ranges:Silver springs 1.3 mm y0730/05 (standard on Big Scale Cross): 5,000 9,500 RPMGold springs y0730/06 1.4 mm (standard on Big Scale Race): 6,500-11,500 rpm Adjustment:Adjustment of the clutch engagement speed is done by one single screw using a 2.5 mm Allen wrench. Turning the screw in increases the stall speed, backing it out will lower the stall speed. The adjusting screw is thread locked to keep the setting. Should you realize that the screw can be turned too easily please re-apply medium strength thread locking compound.Finding the best clutch engagement speed:The best clutch engagement speed should be found while driving on the track, it depends on engine characteristic, track layout, track surface and driving style.It is recommended to start with the lowest setting (which means the set screw just touching the adjustment cam) and gradually turning the adjusting screw in while doing test runs after every adjustment.If you feel that you have exceeded your best engagement speed (clutch will slip too much), back the screw out for a little bit to avoid excessive wear or glazing of the pads.Attention: You must use adhesive y0743 Clutch-Safe when replacing clutch pads!
