Product information "TT0198 Top Tuning Bubble-Ex for 1/10 up to 1/5 scale rc-cars"
Genuine Top Tuning spare/option part.
Indispensable for optimal suspension tuning!
Vacuum container for removal of bubbles from shock fluid when filling shocks.
A vacuum pump is built into the lid. The tray has four holes each to accept 1/10, 1/8, 1/6 and 1/5 scale shocks.
Suitable for shock absorbers from Losi, Mecatech, BWS, Arrma, Traxxas, FG, Carson, HPI and many more, as long as they have a suitable diameter. All shocks from 15 to 32 mm outer diameter can be used in the Bubble Ex to be "de-bubbled".
Tray bore sizes:
No. 1 = 32 mm diameter
No. 2 = 21 mm diameter
No. 3 = 17.5 mm diameter
No. 4 = 15 mm diameter
The maximum length of the shock absorber up to the upper edge of the body is about 150 mm, whereby longer shock absorbers can also be partially compressed for insertion. (e.g Losi 5ive-T and many more)
Operation:
Unlock the vacuum pump by turning it slightly to the left, the pump handle then extends a little. The small plug with handle is used to close and ventilate the container. To build up the vacuum, the plug must be in the down position.
The small membrane on the opposite side serves as an indicator for whether a vacuum is present. Only when this is curved outwards the lid of the container can be opened again without any effort.

Genuine silicone shock absorber oil for the optimal shock absorber set-up. Content: 50 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.

On FG cars the OEM springs can be used as well. Shock versions y1137/07 and y1137/08 for Smartech C5 and FG on-road cars should use spring Shock oil recommendations:The GPM-Spezial Cross shocks are factory filled with 1000 viscosity silicone oil. This gives a very good shock performance at normal ambient temperatures.When a softer shock is required, you can go for 500 or even 600 viscosity oil; 1500 and up if you prefer more damping.One 50 ml bottle fills 5 long or 6 short shocks.For use in a Kyosho Scorpion XXL (version 6), the shocks must be installed with an additional 4 mm spacer at the lower front mount (see picture above). The stock Scorpion springs can be used. We suggest silicone oil with a 100 to 200 viscosity for the front and a 200 to 300 viscosity for the rear .Introductory price! Regular price: 129,90 EUR / set

Genuine Zenoah air filter and / or complete clutch 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.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.

Genuine GRP spare/option part.Glued on GRP off-road disc rim with 18 mm square (für FG, Smartech & other) or 24 mm hex (for Losi, HPI + Co.). GRP is one of the leading manufacturers of 1/5 and 1/6er street; and with its current off-road tires MICRO and CROSS he has the optimal solution for all track conditions and surfaces. As a recommendation: The dirtier the track or the colder the weather, the more grippy (softer) the rear tire should be.Note regarding the front tires: For 2WD cars it should be one to two steps harder than the rear tire. On 4WD models, a tire combination with the same shore hardness front and rear is usually a good choice.Of course, as with all tires, it also applies to the GRP tires MICRO and CROSS: the softer the tire, the higher the wear.The MICRO tire is perfect for astro turf as well as carpet flooring; the CROSS version gives your off-road car the necessary grip on loose as well and firmer soil alike.The following classification should help you with the tire selection, even though it is certainly recommended to find the best possible tire for your individual setup by your own test drives on the track.GRP-MICRO GW90-P1 soft for astro turf/carpet tracks, in colder weather and low grip conditionsGRP-MICRO GW90-P3 medium for astro turf/carpet tracks, but at higher temperatures and good gripGRP-MICRO GW90-S1 soft for clay soil, on colder days and less grip on the trackGRP-MICRO GW90-S3 medium also suitable for natural terrain, at normal temperatures and good grip.GRP-MICRO GW90-S5 hard, for good to very good grip conditions and/or good weatherBut as already said: "The proof is in the pudding", which means that a GRP-MICRO-S tire can also prove to be the best on a specific astro turf track, depending on the tracks condition and weather! And, of course, vice versus with a GRP-MICRO P tire. This applies especially to race tracks with a mix of carpet/astro turf and sorts of natural soil surface sections.As with full scale racing, in RC-car races, the right selection of tires often decides on victory or defeat.Technical note: The outside shoulder of the tires is reinforced and is labeled "OUT" by GRP!Contents:2 pieces
