y0733 Big Scale-EXTREME, adjustable 3 - shoe clutch
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

y0743 Clutch-Safe 10 g, adhesive especially for clutch pads
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

The gained space allows now to use the adjustable GPM Big Extreme clutch.Suitable for genuine slot drive Losi pinions. Comes with bolts and spring washers included.The bolt hole is countersunk from the inside so you can also use a flat head screw from the inside and a nut on the outside if you like. Content:1 pieces

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.Slight aluminum deposits in the clutch bell and corresponding wear marks in the clutch shoes are normal with the Big Scale ALLOY clutch and have no negative effect on the function. Caution: It is very important that when swapping the full-aluminum clutch shoes against the organic friction pads of a Big Scale CROSS or RACE to use a different or new , because the rough surface of the aluminum deposits in the clutch bell left by the Big Scale ALLOY will cause a high wear on the organic pads.

y0039 Oil for shock absorber, all viscosities, 100 ml
Genuine silicone shock absorber oil for the optimal shock absorber set-up. Content: 100 ml Please note: Factory filling of FG/Losi/Smartech and many other 1/5 and 1/6 scale shocks is done with genuine silicone shock absorber oil. To ensure seal tightness and consistency you should only use genuine silicone shock absorber oil for refilling as well.Most every rc-car shock absorber uses silicone oil of different viscosities. The smaller the number, the lower the viscosity of the silicone oil and the softer the damping. As a rule of thumb: Viscosity 100 = similar to water Viscosity 1.000 = similar to cooking oil Viscosity 5.000 = similar to shampoo Viscosity 10.000 = similar to honey As a reference: The red FG Marder / Off-Road Buggy series shock absorbers are factory filled with 2.000 viscosity oil, the shocks on monster cars with dual shock set-ups (total of 8 shocks) are filled with 1.000 viscosity oil, and the shocks on FG onroad cars come filled with 4.000 viscosity oil. The original filling of the Losi 5ive-T is 350cc silicone oil.FG Silicone oil with 100 ml:FG Item N° 66295/010 = Viscosity: 100 FG Item N° 66295/025 = Viscosity: 250FG Item N° 66295/035 = Viscosity: 350FG Item N° 66295/050 = Viscosity: 500FG Item N° 66295/075 = Viscosity: 750FG Item N° 66295/100 = Viscosity: 1000FG Item N° 66295/150 = Viscosity: 1500FG Item N° 66295/200 = Viscosity: 2000FG Item N° 66295/300 = Viscosity: 3000FG Item N° 66295/400 = Viscosity: 4000FG Item N° 66295/500 = Viscosity: 5000FG Item N° 66295/600 = Viscosity: 6000FG Item N° 66295/700 = Viscosity: 7000FG Item N° 66295/800 = Viscosity: 8000FG Item N° 66295/900 = Viscosity: 9000FG Item N° 66296 = Viscosity: 10000Viscosity of silicone oil at various temperatures.

FG Set price: 163,25 EURFits all FG 4WD cars (except FG Leopard/ TR-4!) Lost drive shafts are a thing of the past! Universal drive shafts allow for higher drive angles than dog bones or ball drives. This makes them a better choice for for wheel-side applications on front axles, where the angles of the steering and suspension meet.GPM universals for ball drive can be disassembled and therefore repaired or rebuilded if necessary. The center pin (No.: 66275/02)of the GPM universal joint is secured by a grub screw, which should be installed using a medium strength screw locking compound (y0114).Therefore the joint can be easily rebuilded by replacing the center pin for cheap and will be good as new again.The GPM drive parts are made of high quality spring steel and due to its elasticity provide high impact resistance and extreme stability. Ground bearing seats ensure maximum accuracy of fit. Ball drives run significantly smoother and with less wear than normal dog bones with pins.The GPM universal drive shaft set includes everything for the conversion of your FG 4WD.Set includes:Quantity:DescriptionPart number2 piecesUniversal drive shaftFG 662752 piecesDifferential ball drive cupGPM 6069/022 piecesDriveshaft booty10046 piecesSteel ballGPM 7080/022 piecesDrive shaft spacer springy1218
