To adjust the correct backlash between
the motor pinion and the main gear
loose the 4 motor mount bolts on each
side , then fix them tightly with
threadlock.
Gear backlash adjustment:
For smooth operation and
performance, it is necessary to adjust
the gear backlash properly. Excess
gear backlash can cause premature
gear wear and damage. Insufficient
gear backlash can cause vibration, as
well as overheating of the Motor and
speed controller. Adjust the gear
backlash by placing one piece of
paper between the gears to set the
distance. When the bolts are secure,
remove the paper and test the gear
backlash to insure that there is a
slight amount of free movement
between the gears.
Motor Setup And Maintenance Tips
: Use at least 5.5mm gold connectors with an even
surface for your motor wires and ESC wires. Use heat shrink and look for a good isolation. Check
all wires and connectors regularly for good fitting and damage. Damaged wires and connectors can
cause severe damage to your model and equipment! Oil the motor bearings each 10 flights and
change them if they make strange noises or when the motor gets clearance at the shaft or bell.
Soldering Tips : Use a soldering iron with atleast 80W and SN60PB40 brazing-solder. The
temperature should be around 380°C. Use a non-conductive heat resistant surface and clamps or
pliers to hold the connectors and wires. Do not heat the connectors and wires to long. The braze
point must be shiny and even. If you have problems with the soldering, ask a experienced modeler
for help. Due to extreme high currents of up to 200 Amps and mechanical stress to the connections,
good soldering points are very important to guarantee a safe function of your power system.
Tip
: Use a pressure resistant extra sticky grease on the maingear to reduce abrasive wear and
noise. Grease it every five flights for the first 20 flights. Check the gear backlash especially in the
first 20 flights. Apply some grease when you recognize that the main gear gets „dry“.
Use medium threadlock on all
screws going into metal parts
