Sintered steel clutch for Zenoah and many other rc-car engines from 23 cm³ to 32 cm³. incl. clutch spring!Note: The sintered steel clutch needs a break in period of at least half an hour run time after their first installation. Only then the clutch surface reaches the desired grip and provides the necessary friction. After that the clutch will show consistent operation and extremely low wear!With 80 grams the weight of the clutch is about the same as the usual OEM clutches.As with all non-adjustable clutches a periodic monitoring of the clutch spring is recommended. By changing the spring, it is also possible to match your car to the track conditions, i.e.: the harder the spring, the higher the stall speed of the clutch.If not on hand, for installation of the sintered steel clutch a clutch spring, the Zenoah screw set # 7318 and the original Zenoah clutch mount # 7315 are required!

The spark plug tester wiil be put in line between the spark plug in the engine and the spark plug cap. When the spark plug is in good working order, pulling the recoil starter will produce a spark easily visible in the clear section of the tester (see video!).

Special single component epoxy adhesive for bonding clutch shoes; suitable for extreme operating temperatures (up to 200°C!) Important note for processing: For the final cure of the bond Clutch-Safe must be tempered at 170°C for 1 hour! (1 hour at 170°C in the oven!) The extremely high temperature load on the clutch shoes when used in off-road cars caused by increased clutch slippage, the shock of jumps and the combination with sometimes very high vehicle weights (up to 18 kg!) make bonding with Clutch-Safe highly recommended. For later removal/replacement of worn out clutch pads the clutch shoes must be heated as well.Attention:Clutch-Safe adhesive must be stored in the fridge! Content: 10g tube

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.

Same dimensions as the Zenoah G230, G240, G260, G270.New generation Zenoah engine with 28,5cm³ cylinder capacity and approx. 3.9 hp. The cylinder is fixed with 4 screws. The technical details are identical to the Zenoah engines G240RC and G270RC.The engine will be delivered with pull starter, carb and spark plug / spark plug cap. Genuine Zenoah air filter and / or complete clutch and / or ball beard carburetor are optionally available at additional charge. 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. Attention! We recommend to run exclusively fully synthetic 2-stroke engine oil, like y0813 Motul 800 racing oil.

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
