Effect Of Manner Of Driving On Individual Components - Reely 1:8 GP Buggy Ultra Sonic 4WD RtR Notice D'emploi

b) Effect of manner of driving on individual components
Engine
The model's FORCE combustion engine is air cooled. This means that the airstream has to take care of cooling the
engine (air cooling).
This is why you should try to avoid to accelerate 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
blocks 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:
In the case of continuously driving slowly the wind cooling of the engine is guaranteed, but instead there may
be damages on the clutch (wear, overheating through slipping clutch).
Clutch
The clutch will not engage at idle speed. The model keeps standing still with running engine.
In case of slowly increasing the rotation speed, the clutch 'slips'. The vehicle starts and drives slowly. Just as with a
'real' car, constant slipping of the clutch can cause the clutch lining to "smoke away" or "burn off".
The clutch first engages with high engine rotation speeds. The engine rotation speed is transmitted to the drive strand
without slipping. 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 get 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 therefore an additional heating up of the engine
shaft.
