Effects Of Manner Of Driving On Individual Components - Reely LEOPARD4WD Stadium Buggy 1:8 Bedienungsanleitung

7. Drive operation
b) Effects of manner of driving on individual components
Engine
The engine is air-cooled. This means that the air stream takes on the cooling of the engine (air cooling).
This is why you should try to avoid accelerating the vehicle with frequent, strong load changes (short throttle bursts from low rev range and jerkily lowering
the revs).
The brief high revs strongly heat up the engine, without there being appropriate cooling through wind, as this would be the case at a drive with constantly
high revolutions (high speed). As a result of overheating the engine, the piston may get stuck in the cylinder liner (piston gets stuck) and suddenly block
the drive. This could cause consequential damage of the entire drive section.
Drive in part-load operational range with revs that correspond to the desired speed.
However: When driving slowly continuously, the cooling of the engine through air stream is guaranteed, but instead, there may be damages on the clutch
(wear, overheating through slipping clutch).
Clutch
The power of the engine is transmitted via the center differential to the drive section.
- At idle speed the clutch doesn't yet grip, the model remains stationary with engine running.
- When the revolutions are slowly increased the clutch "slips", the vehicle moves forward or starts to move slowly.
As with a "real" vehicle, constant slipping of the clutch can cause the clutch to "smoke away" or "burn off".
- Only at high engine revs does the clutch start to "engage", the engine speed is transmitted without any slip to the
drive section. The wear on the clutch linings is now at its lowest.
- Frequent, strong load changes by brief short throttle bursts and jerky lowering of the revs also reduce the life of the clutch linings.
With short throttle bursts as well as by letting the clutch slip, you achieve a slow speed, but at the expense of the clutch.
Bearing
Overheating the engine and/or the clutch also has an effect on the bearings of the clutch bell.
Leaking and toughening of the bearing grease (running dry of bearing) as well as different expansion of the balls and the ball bearing case in the case of
excessive heat, can lead to a jamming of the balls. If the balls can no longer move freely, there are frictional losses and therewith an additional heating
up of the engine shaft.
8. Set-Up
After the running of the engine, the model is basically ready for use and roadworthy.
The driving characteristics of the model are suitable for first trial runs as well as for advanced drivers. However, with a better knowledge of driving, the
demands on the model will also grow. These demands depend on the driving style of the respective driver and his/her ambitions, regarding a high end
speed, maximum torque, just for fun or use at competitions.
Tuning
The chassis satisfies the ambitious model pilot through the various possibilities of chassis tuning. The inclination of front and rear wheels can be adjusted
continuously in a large range via clamping screws in the upper transverse control arms. Clamping screws in the right and left steering link also allow for
a continuous fine-tuning of the alignment.
The spring preload of the four oil dampened shock absorber as well as the progressivity of the damping can be modified by using spacer rings and
changing the angle of attack of the oil dampened shock absorber.
The accessories contain silicone oils of different viscosity for the oil dampened shock absorbers as well as differential oils of different viscosity with which
you can have an impact on the block function of the front and rear axle differential.
