Ltd. 2.1.1 Hangaring, Parking, and Ground Handling 2.1.1.1 Tie down and ground-towing Do not leave FES equipped sailplane outside on the rain, unless it is completely covered with high quality all weather covers. Protect motor and battery compartment from water entering. Take Battery packs out of the glider and store them on dry place, and not on direct summer sunlight, in order to prevent to be overheated.
Ltd. 2.2 Rigging Not affected. 2.2.1.1 Installation of Battery packs into sailplane: Make sure that both battery packs are fully charged before Warning: installation into sailplane. Both battery packs must have approximately the same voltage level of each cell (close to 4.16 V per cell). There should be less than 0,4V difference, between total voltage level of each battery pack! ...
Ltd. 2.3 De-rigging Not affected. 2.3.1.1 Taking Battery packs out of sailplane: Check that Power switch (or Key switch at Silent) is OFF Check that FCU instrument and all other instruments (Flight computer, Flarm, Radio, Transponder, PDA...) are switched OFF ...
Ltd. 3.1 Mandatory Maintenance In this section there is defined a list of inspections to ensure safe operation of FES during its lifetime. The periodical inspections shall be performed by qualified staff authorized to perform the work at the time of sailplane inspections. 3.1.1 Inspections periods ...
Ltd. 3.1.4 Motor – Propeller After propeller change (each 200 motor hours) Motor – propeller assembly must be balanced to the vibration value lower than 0,1 IPS. 3.2 Regular Maintenance 3.2.1 Annual inspection It is necessary to check the sailplane every 12 months in accordance with the 100 flight hours inspection.
Do not at all simply keep on using the drive. Be especially aware of cuttings which can almost irremovably stick to the magnets. In this case, the only thing that helps is a disassembly of the drive by the manufacturer. For detail description refer FES HPH M100 MOTOR manual. Document No.: 304eS/MMSupp...
Cracks or deformations in a center part of the propeller are not allowed. If such occurs, send propeller back to manufacture for the overhaul.
