Congratulations, you have just purchased the

RimFire 35mm power system components. All

the components are sold separately to allow

you to customize your power system to your

airplane.The components needed to assemble

your RimFire 35mm power system are: RimFire

35mm motors, propeller, propeller adapters

and brushless speed controls. This instruction

sheet explains how to determine what you will

need and how to assemble each component.

The RimFire motors are labeled to provide the

most information at a glance. For example: the

35-48-850kV is 35mm in diameter, 48mm long

and has a kV (rpm-per-volt) of 850 rpm.

MOTORS

An ESC is basically the device that controls

your motor through your radio system. Never

run any RimFire motors with a brushed ESC.

It will not work and you may damage both the

motor and the ESC. Always use a brushless

ESC. ElectriFly offers Brushless ESCs that

will work with the RimFire 35mm motors.

ELECTRONIC SPEED CONTROL (ESC)

The RimFire Motor/Silver Series ESC

combination can use NiMH or LiPo batteries.

Typically, NiMH batteries are heavier but much

more affordable for the same capacity as LiPo

batteries. If you want a very light, high-

performance airplane, you might want to use

LiPo batteries, but if weight is not a concern,

then NiMH batteries might be for you.

BATTERIES: CHEMISTRY

Cells can be connected in series or in parallel.

Usually batteries are labeled as 8-cell NiMH or

3-cell LiPo.This means the cells are connected in

SERIES (S). Arranging batteries in series gives

you more power (higher voltage).

• Each NiMH cell has 1.2V, so an 8-cell

NiMH battery has 1.2x8 = 9.6V

• Each LiPo battery has 3.7V, so a 3-cell

LiPo battery has 3.7x3 = 11.1V

If you need a higher voltage than what is

available in the LiPo battery line, you will need

to connect two battery packs together in series.

If you need a battery voltage of 14.8V you can

use the Series Y-Connector (GPMM3143) to

connect two 7.4V batteries together.

BATTERIES: NUMBER OF CELLS

There is a wide selection of propellers

available for electric use. The RimFire 35mm

motors use high performance slow fly electric

props.The larger the propeller used, the more

current your motor will draw. The smaller the

propeller, the less current the motor will draw.

Shown are a few of the recommended electric

props. Due to the large range of propellers

and the constant addition of new sizes, visit

our web sites at www.electrifly.com and

www.greatplanes.com for the most up-to-

date listing of electric type props.

PROPELLERS

The RimFire 35mm motor comes with a prop

adapter that mounts directly to the motor

case. If the RimFire 35mm motor needs to be

mounted so that the prop is mounted on the

motor shaft, the motor requires a 4mm prop

adapter collet type (GPMQ4965), or set screw

type (GPMQ4936).

If a battery is arranged in PARALLEL it might be

labeled as (P). Arranging the batteries in parallel

will give you more duration (more capacity).

All LiPo batteries have a rated discharge that

must not be exceeded or the battery will be

damaged. They may say 15C max. discharge

rate or 20C max.discharge rate.This means that

the discharge rate (current draw of the motor)

must not be more than 15 or 20 (15C or 20C)

times the capacity of the battery. The capacity is

expressed in milliamp hours (2100mAh). It can

also be expressed in amp hours (2.1 Ah).

A LiPo battery with a capacity of 2100mAh with

a 20C discharge rate can be discharged at 42

amps, 2.1Ahx20C = 42 amps. If the power

system draws more than 42 amps, the batteries

GPMQ4965 4mm Collet Type

• ElectriFly Silver Series 45 (SS-45) ESC

(GPMM1840) for 45A maximum constant

current draw.

• The Silver Series 60 (SS-60) ESC

(GPMM1850) for 60A maximum constant

current draw.

• The Silver Series 80 (SS-80) ESC

(GPMM1860) for 80A maximum constant

current draw.

These ESCs come with 4mm female bullet

connectors that require an adapter

(GPMM3123) to plug into the 3.5mm male

connectors installed on the RimFire 35mm

motors. Also, these ESCs come with a

The ElectriFly Brushless Medium Motor

Mount combines the ease of installation with

the adjustability to fit most motor applications.

The Medium Motor Mount is designed to fit

the bolt pattern of the Great Planes .20-.48

and .40-.70 Nylon Engine Mount. This easily

allows the conversion of a glow powered

plane to electric powered.

will have to be connected in parallel to increase

the capacity.Two 2100mAh batteries in parallel

have a capacity of 4200mAh or 4.2Ahx20C =

84 amp discharge rate.

ElectriFly offers a full line of NiMH and LiPo

batteries. Airplanes that use the RimFire

35mm motors will typically use batteries with a

capacity of 2000 to 3600mAh with the higher

capacity batteries delivering more flying time

but also being heavier.All of the batteries have

connectors that fit the recommended ESCs.
