CAUTION
While lubricating teeter hinge (especially with new bush bearings and related
close gap dimensions) it may be possible that only very small amounts of
lubricant pass through the grease nipples on the rotor. In this case, do not
press too hard but better remove the bolt, lubricate the outside and re-install.
Use a new split pin!
8.10 Replenishing of Fluids
8.10.1 Engine oil
See engine manufacturer’s manual.
8.10.2 Engine coolant
See engine manufacturer’s manual and the aircraft maintenance manual.
8.11 Engine Air Filter
The air intake filters need to be replaced or cleaned according to the manufacturer‘s
recommendation. Depending on environmental conditions, such as dust, sand, or pollution
the recommended rate of maintenance should be increased as required. Engine cowling
must be removed!
8.12 Propeller
Clean regularly as contamination will noticeably decrease its efficiency, resulting in a
negative effect on both aircraft performance and noise emission. Use either pure water or
add mild cleaning additives. Let contamination soak, then remove with a soft cloth or micro
fibre material and rinse thoroughly with water. Check for erosion and damage, especially at
the leading edge and blade tips. Check tight fit at the propeller blade root or any unusual
sound when tapping the blades, in case of a variable pitch propeller. If in doubt or if damage
is obvious, consult RotorSport UK or your aircraft engineer. Minor chips may be repaired.
Consult the AMM or propeller MM for detail.
8.13 Battery
The aircraft is fitted with a EP-13 maintenance-free gel electrolyte battery. Maintenance is
therefore limited to outside soundness, correct attachment, and cleaning. Check integrity of
the battery as leaking fluid contains corrosive sulphuric acid which would lead to extensive
damage when contacting the framework and attachments.
Charge the battery only with a charging device which is suitable for gel electrolyte batteries.
CAUTION
The battery must never be deep discharged, as it will be damaged. If so, it
might need to be replaced.
