weight and torque specifications will adversely affect flight performance and are not recommend. Note: During assembly when it’s time to mount the servos, you will be instructed to glue them in. Do not be alarmed as this is a common practice with this type of lightweight, high-performance model. Should servo removal ever be necessary for repair, replacement or transfer to another model this can be done by prying them out with a hobby knife or a small screwdriver.
Receiver
The lightest, four-channel receiver is recommended and must be compatible with whatever servos will be used (not all servos are compatible with all receivers–even servos and receivers within the same brand). The Futaba R-114F Micro receiver is recommended and is compatible with the 3108 servos recommended. Note: Futaba receivers are sold on high and low bands and come without crystals. Following are the order numbers for the R-114F receiver and compatible crystals:
| Low Band | High Band |
| (Channels 11-35) | (Channels 36-60) |
R114F Receiver | FUTL0442 | FUTL0443 |
Crystal | FUTL62** | FUTL63** |
**Replace the “**” in the order number for the crystals with the preferred channel number. For example, if you want to fly on channel 33, order a low band receiver and crystal number FUTL6233.
Battery
The EP Zero ARF requires a 3-cell (11.1V), 1250–1500mAh lithium-polymer (LiPo) battery capable of providing 7A continuous discharge current. The ElectriFly™ 3-cell, 3-Series1250mAh battery pack is recommended (GPMP0823).
Speed Control
An electronic speed control capable of handling a minimum of 15A continuous current is required. Additionally, the speed control should be as light as possible. The ElectriFly C-25 High-Frequency ESC w/BEC (GPMM2025) is suitable.
Charger
A charger capable of charging 3-cell (11.1V) LiPo batteries such as the ElectriFly PolyCharge 1 to 3-cell LiPo charger (GPMM3010) must be used. If using another charger, it must be a LiPo charger or have a LiPo charge mode. Never charge LiPo batteries with chargers not intended for LiPo batteries or chargers on NiMH or NiCd settings. Overcharging or explosion may result. In addition to the PolyCharge, the ElectriFly Triton™ (GPMM3150) or Accu- Cycle Elite™ (HCAP0280) are also suitable chargers.
Battery Charging Leads
Many chargers (including the Triton and Accu-Cycle Elite listed above) do not include charging leads, but rather have banana jacks to plug the leads into. If this is the case with your charger, you will need to purchase a charge lead to match your battery.
Glue
Although it is safe to use foam-safe CA, it is not recommended for assembly of the main fuselage components as it may wrinkle the lightweight covering and cause the covering to come loose from the foam. Therefore, epoxy should be used throughout the building process unless foam-safe CA is recommended for a particular step.
