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
The new adjustable system features three carbon pads with special 2.4 mm springs.Weight of the complete clutch is 70 grams. Very wear resistent when running with the recommended clutch bells.Adjustable friction points: First gear - 8.500 U/min. Second gear - 9.300 U/min. Third gear - 10.100 U/min. Fourth gear - 11.000 U/min.With tool #5445 the engagement speed can be adjusted to different settings within a range from about 8,500 to 11,000 rpm.
Reinforced spring for Zenoah OEM clutch with 2.7 mm wire diameter and five coils. Engagement speed is around 7500 rpm, which allows the engine to build up more power and torque for accelleration.Fits Zenoah, CY and most other engines in the 23 - 30 cc range with stock clutch.
Genuine FG spare/option part. Fits Zenoah G230/260/240/270/290/320.Reinforced clutch spring for the Zenoah standard clutch. Engagement speed approx. 8000rpm. The engine has a higher torque and therefore more power for acceleration according to the raised operative speed. Suitable for all Zenoah engines.Contents:1 piece
Genuine HPI spare/option part. Spare part for #15448 Baja 5B High Response Clutch Shoe/Spring Set. When used as standard, the clutch will engage at 8000RPM, which is great for low-grip or muddy surfaces. If used with #15440 Clutch Shoe/Spring Set, the clutch will engage at 7000RPM, ideal for high-grip surfaces.Content:2 piece

Compatibility Zenoah / Losi 5ive-T:Please note that for installation in a Losi 5ive the fan cover must be swapped for a Losi or CY cover #5341 in order to fit the chassis" bolt pattern.If you want to install a Zenoah engine into the Losi 5ive, you usually have to use a fan cover from the CY engine.However, there is a workaround to maintain Zenoah fan cover.The adjustment is done via the pinion specific mounting plates for the engine. The change always affects only the rear, outer (carburetor side) plate under the fan cover. This is rotated by 180°; so that the embossed number on this plate faces the exhaust side of the engine!18T pinion: use 20T plate, rotated 180°19T pinion: use 19T plate, rotated 180°20T pinion: use 18T plate, rotated 180°On the plus side you gain the opportunity to easily mount a Zenoah engine keeping the original fan cover. On the other hand there will be the disadvantage of the necessity to combine two different sets of engine mounting plates when installing any pinion other than the stock 19T version. Therefore we do not recommend this workaround for everyday use. Nevertheless it works perfectly should ever the need arise.Zenoah G320RC with Walbro WT 1107 carburetor (also available in the ball-raced version through the shop's options menu)With 32 cm³ and 30% more power than the Zenoah G290.Significantly more torque and higher stamina due to larger sized bearings all around, with Racing Carburetor Walbro WT 1107.The motor is supplied with WT-1107 carburetor and spark plug.SpecificationType: Two stroke gasoline engineDisplacement: 31,8 cm³Bore: 38 mmStroke: 28 mmWeight: 2,3 KgOverall Dimension:Length: 167 mmWidth: 215 mmHeight: 196 mmMaximum Output: 4,6 PSMaximum Torque: 2,00 N-mRotation Direction: CounterclockwiseCarburetor: Walbro WT-1107Spark plug: CMR7HStarting: Recoil starterFor all HPI Baja 5 cars the G320RCer clutch housing has to be shortened at the mounting base, for Losi 5ive- T and Desert Buggy XL cars the clutch housings overall length must be shortened to CY size.When installing the air filter you must pay attention to the length of the screws.For use on Losi and HPI we recommend M5x45 screws (like H94763); you can also cut existing screws to length, of course.When ordering with a modified clutch housing we will include these screws!In our shop you can select from Zenoah G320RC engines already modified to fit your HPI or Losi car.The installation of the Zenoah G320RC in other cars (like FG or Smartech buggies / monsters a.s.o.) is not even remotely straightforward, since the layshaft pinion (the small pinion in front of the big differential spur gear) is in the way for the larger Zenoah G320RC crankcase.Compatibility Zenoah / Losi 5ive-T:Please note that for installation in a Losi 5ive the fan cover must be swapped for a Losi or CY cover #5341 in order to fit the chassis" bolt pattern.If you want to install a Zenoah engine into the Losi 5ive, you usually have to use a fan cover from the CY engine.However, there is a workaround to maintain Zenoah fan cover.The adjustment is done via the pinion specific mounting plates for the engine.
