Item N° 6432/17 Steel gearwheel 17 teeth, profile displaced, 1 pce. True running steel pinion for minimized wear. Suitable for all FG cars except Formula 1. Profile regraded, this means that the number of teeth is changed while the diameter remained constant. The part of the involute curve that defines the tooth profile is changed. Positively regraded (lower number of teeth) pinions are stronger and run smoother, the reduced strength of negatively regraded pinions doesn't really matter.
23 cm³ Zenoah engine for large scale cars!Please note: contrary to their new designation the displacement has not been increased! The outer dimension didn't change, so you don't need any additional parts for the engine swap!The engines feature the following improvements over their G230:Quantity of cylinder mounting bolts increased from 2 to 4Improved strength of crankcaseAdded additional bearing on the PTO (clutch) side of crankshaftRedesigned shape of cylinder finsDimension of air intake port is 5% widerContains internal fuel pump which increases acceleration from idle to wide open throttle.Removal of choke valve increases performance by increasing air flow to the carburetor Changed material of the insulator gasket to metal, which improves sealing performanceThe 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.
HURRAX extreme Race tire and insert 175x70 mm HURRAX extreme is one of the most successful tire in large scale off-road racing and specifically designed for astro turf and solid ground. With more than 700 (!) differently designed, closely spaced lugs and the 70 mm wide tread it is reasonably wear resistant and provides optimal grip with good side traction. If this - i.e. on the front axle - is not desired, you may cut the lugs at the tires outer edge to reduce cornering grip. This can be easily done with a small side cutter or strong nail scissors. In order to reduce the edging in the tire on the front axle.This makes a tire less aggressive during cornering and changes the cars behavior towards understeer. It becomes depending on the track conditions (i.e. wet!) a lot more drivable.An optimal vehicle setup can often be achieved by running already used HURRAX extreme tires on the front and new ones on the rear axle.This is especially true for 2WD models. Dimensions:External diameter approx. 175 mmInner diameter approx. 130 mmWidth approx. 70 mm HURRAX extreme tires are available in soft (blue marker!) and medium through our shop menu.Contents:2 pieces tires2 pieces inlays
