EP CONCEPT has come to fly well by a conference room of communication by personal computers.
I am able to reconstruct 30size GP Helicopter electromotion by reason of the following with thought.
It is machine parts and technology that received it from EP CONCEPT.
It is technology and knowledge and also the machine parts that accumulated with this.
It is able to materialize with less money than (540 motors and 8 cells of nicad battery) are utilized.
2 It is the result of a trouble.
Actually an electromotion shuttle has come to fly well.
Until they are 5 minutes fly without fail.
After all 30 classes are stabilizing.
Also it is easy to fly.
It is maintenance even a little to it.
3. It is a reconstruction method.
(1). MOTOR.
Now 2 DYNATEC02H be being used. (made TAMIYA)
This was made from L angle on motor basis to a mainframe attaching be.
An attachment position becomes an aspect the that pinion giar is.
Electricity wiring is series connection.
(2). Electricity control unit.
Because it is intended to utilize the machine parts that were using it until now FX35D was used.
It became series connection of 16 cells on the performance of an amplifier.
It was a correct answer with a series drive as.
When it is a series drive rotation of 2 motors take a trouble of synchronizing and a condition is good very.
Yet, drawing a line particularly from places of 8 cells of batteries because we wanted to use BEC for the power supply for a receiver a direct conectline be being done to 3 terminal Regurter IC.
Pay attention, because the auto is sometimes cut and an amplifier generates too much, when BEC is used in 16 cells.
(3). Reduction gear.
2 decelerations needed to be made, to use 540 motors. A gear of KYOUKU GEAR
WORKS MADE was used.
S1S8L-1206 it is attaching to a motor with (a propeller adapter of YOSIOKA)
S80B25B/S80D64B-0506 it is.
The gear that used it is a standard article for an industry.
(4). BATTERY.
SCRC-SP1700mah8 cell of SANYO is been 2 use total of 16 cells. A battery is good this for the present.
(5) Reduction of weig.
The most important job is reduction of weight.
It is the reduction of weight of each part.
It is exchanging a mast to a stainless steel pipe.
(6). Rotor.
As for the one that is a symmetric rotor resistance too many, the rotation number does not up.
The one that is a half symmetric rotor is suggesting.
It is good use a twist reduction rotors for SHUTTLE ,made of JRC.
However, there is much this consumption electric power.
I am using and am doing am winding a narrow rotor of the width of the purity for a SHUTTLE a glass.
As for this a consumption current is few.
Even performance can be satisfactory.
(7). GYRO.
PEZO GYROis good.
It is a steering sensor.
This is light and performance is high.
