Wiring Tips
Never use RC-components with damaged
wires. Check all wires for damaged isolation
and breakage. Control all servo connectors for
a tight fit and be sure no wire is loose in the
connector.
All wires must be protected against damage
through sharp edges of the carbon frame and
metal parts. Zip ties can also cause damage to
the wires.
Tip:
Cut open a piece of fuel line to cover sharp edges.
You can also use fuel lines to cover zip ties to
prevent them from damaging the wires.
Keep all wires as short as possible. Avoid unnecessary extensions and connections, but use extensions if a
wire is almost to short to avoid mechanical tension in the wiring. Never tighten a wire to much. Be sure that
nothing pulls at a wire. It is very important to have zero tension between wires, plugs and RC-Components.
Do not pull out connectors by pulling at the
wires!
Keep all wires away from rotating parts,
linkages and servo arms.
Tip:
Use a plier to bend zip ties before you use
them. It wil be easier to get them around a corner.
Control all wires and connections regularly to discover hidden damages and defective
contacts early. Never go flying if any failure occurs!
Carbon fibre and metal parts are
conductive . Open wires, contacts and
open gaps between two contacts
touching the frame can cause a short
curcuit and damage to the RC-Equipment.
the RC-Equipment.
Tip:
The best way to protect your wires is to use
braiding sleeve such as those used for
computer wiring or casemodding. Seal the
ends of the sleeve with heat shrink to prevent
them from unraveling. You can also you use
heat shrink to protect wires where zip ties
overlie.
Do not fold any wire, place them in curves.
Tip:
Secure connectors with heat glue at the receiver and
FBL-Unit. Avoid contact of the glue with stickers and
the wires. The glue is easy to remove.
Be careful when heating heatshrink on wires,
don´t heat it up to long or with to much heat
or it may damage the isolation.

  • Page 3 Wiring Tips - Batteries This is how I wired and set up my batteries to minimize total wire length from battery to ESC. Keeping this short (less than a foot) is important to keep ripple voltage well under 2 volts. Otherwise bad stuff can happen.

We can't give during the setup, please use something long you any specific tips because most brands and straight (like a flybar or CF-Tube) and put it of FBL-Units change their software from on the upper servo mount behind the servorods.

  • Page 7: Blade Tracking

    My kit came with Compass blades. They came with two 2mm thick spacers to put between the blades & the blade grips. They are too thick and you need four spacers, not just two, so you can follow this.

Right now I am running my Castle Creations ICE2 HV 160 ESC: Throttle Type Governor - Fixed RPM Initial Spool Up Head Spd Chg Governor Gain (I may run this as high as 12 later, but too high a setting can damage batteries by pulling too much current, so I’m easing up to it.)

  • Page 10 Travel Setup Now that I have three R/C helicopters, I wanted a way to transport them more safely such that they wouldn’t collide into each other or slide around the vehicle. I purchased a 2 x 4 foot hardboard from Home Depot. On top of that I stuck plastic wiring clips (about $3 for 4) that latch to secure the helicopter skids.
