Electric Metal Gear Pump for Smoke System 32%


Package Contents:

²  1pcs* Pump

²  1pcs* Screwdriver for detaching pump

²  2pcs* Fuel Nozzle

²  1pcs* Plug Screw

²  1pcs* O-Ring

²  1 group* Metal Gears

Description:

The gear pump we are selling is the best seller of our company. Instead of using expensive imported smoke pump, DIY the fuel pump reflects high cost performance. 

However the RC fans leave much to be desired when using it since this fuel pump was used as water pump. At present, there are two problems revealed: 1. the original plastic gear is delicate; 
2. long time usage easily cause oil leak.

 Last year, we have developed a set of metal gear according to the feedbacks of our customers, with which we solve the problem of delicate. This time, we present a full set of DIY accessories to solve the problem of oil leak once for all.

Recommended Equipments:  

²  20A ESC (Item No.: ESCY-20A )

²  Electric Capacity

Kindly Remark:

1. Pump should not be idled continuously for a long time; otherwise the gear and sealing parts will wear out.

2. The fuel pipe must be connected to fuel tank firstly, and then power on the pump to work.

OS 8# No.8 Standard Glow Plug for OS Engine 28%

How to choose the No.8 glow plug for engines for RC Models?

1. for R/C Aircraft:

Suitable for most O.S. Engines

2. for R/C Helicopter

Suitable for most O.S. Engines

3. for R/C Cars

General use, 1/8 Off-road racing

Engine types: 12/15CV, 15LD, 21RG and 21RZ-V 01b

When to replace the glow plug?

Apart from when actually burned out, a plug may need to be replaced because it no longer delivers its best performance, such as when:

Filament coil has became distorted.

Filament surface has roughened while.

Foreign matter had adhered to filament or plug body has corroded.

Engine tends to cut out when idling.

Starting qualities deteriorate.

Glow plug Life:

Particularly in the case of very high performance engines, glow plugs have to be regarded as consumable items. However, plug life can be lengthened and performance maintained as follows:

Fit a plug suitable for the engine.

Use fuel containing a moderate percentage of nitro unless essential for contest use.

Do not run the engine lean, or leave the plug connected while adjusting the needle-valve.

Use a fuel containing as low nitro as possible.

Hobbywing RC Model UBEC-8A Max 18A 5V 6V (2-3S) Switch-Mode DC-DC Regulator 20%

 

 

The 8A-UBEC is a switch-mode DC-DC regulator supplied with a 2-3
cells lithium battery pack and it outputs a consistent safe voltage for
your receiver, gyro and servos. It is very suitable for RC helicopter
(above 30 class) and big fixed-wing aircraft.


Compared with the linear mode UBEC, the overall efficiency of the
switch-mode BEC is much higher, so it can extend the working time
of the receiver battery pack, and because a switch mode UBEC can
significantly reduce the heat emission, it can avoid the loss of control
caused by the over-heat problem which is frequently happened with the
linear mode UBEC.

 

1  Specification
1.1 Output Voltage: 5V or 6V (Changeable with an output-voltage
     select switch )

1.2 Continuous output current: 8 Amps
1.3 Burst output current: 15 Amps
1.4 Input: 6V-12.6V (2) 
1.5 Quiescent current: 60mA
1.6 Size: 42mm*39mm*9mm (length*width*height)
1.7 Weight: 34g

  2   Features 2.1 Designed with an advanced switch mode DC-DC regulator IC. 2.2 The output current is very large. 2.3 With the output short-circuit protection function. 2.4 A metal shield covers almost all the electronic components, and a specially
      made filter is attached with the output wires to significantly reduce the electro-
      magnetic interference.
2.5 Automatically detects the number of the lithium battery pack (2 cells or 3 cells). 2.6 Shows the battery capacity with 4 indicators (LEDs).   2.7 Shows the working status with an indicator (LED), lights when the output is in
      normal range.
2.8 There are 2 output leads to reduce the resistance when connecting the UEBC
      to the receiver
