INSTALLATION

Fourtitude (ARF) Smoke Tank
Starting with the smoke tank, we highly recommend the Fourtitude R/C Almost Ready to Fly (ARF) Smoke Tanks. They include a high-quality double-sided hook and loop mounting strap, & precut foam mounting pad.
If you prefer to build your own tank, it should be assembled with three lines: a line for the non-filtered pickup (clunk), a vent line and a fill line. Per the Fourtitude ARF tank pictured, a fill line that is bent toward the tank floor facilitates filling as well as draining the tank.
Caution: Do not use a filtered clunk on the smoke tank. The higher viscosity smoke oils have difficulty flowing past the filter.

TANK PLACEMENT

It is ideal to install your smoke & gas tank(s) on the aircraft’s center of gravity (CG). As fluid is consumed, the CG remains stable throughout a flight. In reality, most ARF airframes today position the tank(s) in front of the wing tube to accommodate the canister muffler/tuned pipe tunnel below the wing tube.

Pump Mounting & Placement

Important Simple Gravity Physics to maintain pump prime**

caution

• Mount the pump behind the smoke tank.
• Position it at or below the same horizontal plane as your tank mount with the pump fittings vertically positioned.

Following these mounting instructions guarantees the pump will maintain its prime throughout the entire flight. It also ensures the pump remains properly lubed.
The two mounting tabs on either end of the pump housing are designed to accommodate a single grommet/mounting screw. The mounting procedure is simple: Drill two 1/16” pilot holes centered on the mounting tab holes, apply a drop or two of thin CA to the pilot holes and mount the pump. Take care to allow a slight amount of movement. Vibration isolation is lost if the screws are fastened too tight compressing the grommet.

PLUMBING

Install the provided in-line Filter w/ Stainless Steel Screen on the tank’s clunk line. Please do not eliminate this critical installation step, as the fluid must be filtered prior to entering the gear pump. Please be particularly careful to keep the smoke fluid as clean as possible. It is highly recommended that an additional inline filter be used on your smoke fluid storage can. As the gears of the smoke pump have tight tolerance, even the smallest amount of contamination can jam the mechanism. A CLEAN PUMP IS A HAPPY PUMP AND WILL PROVIDE MANY HOURS OF TROUBLE FREE OPERATION!

Install the provided in-line Smoke Check Valve(s) on the smoke fluid delivery line to the mufflers. The check valve(s) are critical components. They ensure instant smoke on/off smoke response without loss of pump prime. Assuming a twin muffler installation, use the (2) one way check valve(s) to transition between the provided high temp Viton tubing and the Tygon fluid delivery line
(client sourced). You can verify the direction of flow with a blow test. Air will only move through the funnel shaped valve in one direction. The funnel shaped end should point toward the muffler.

Hint: high temperature tolerant tubing (Viton) is provided/required as low temp tubing such as Tygon will melt at the smoke muffler pressure fittings. Viton is provided/recommended over Neoprene as it has a much longer useful life. Neoprene eventually hardens and cracks. To ensure the high temperature stays attached to the muffler, place a small piece of heat shrink tubing over the end of Viton at the muffler fitting to secure the connection. Small zip ties are also effective.

Install the fluid delivery line(s) to the smoke pump.
Remove the silicon tubing from the pump input & output nipples and discard. The left nipple is the pump input and plumbed to the tank pickup (clunk line). The right nipple is the pump output and plumbed to the smoke mufflers.

Caution: Should you need to remove any tubing, slice the end to relieve undue stress on the component. The gear pump is fiber reinforced plastic, undue force will break the plastic fittings. Broken pump barbs are not covered under warranty.

Secure and route all tubing connections. Take care to route the high temperature tubing away from the hot mufflers preventing chaffing/rubbing. Secure all tubing connections with a small zip tie. Heat shrink tubing also works very well!

WIRING

The Holy Smokes pump ESC has two leads (signal – black/white wires & power – red/black wires). The signal lead is plugged directly into the active port (e.g. Aux1) on your 2.4 GHz Receiver. The power lead can be plugged directly into any unused port on your 2.4 GHz Receiver (exception: bind port). It requires no auxiliary battery or external on/off switch. If desired an external 2-3S LiPo battery can be used to power the unit

Caution: If running a serial bus protocol setup (JR XBus or Futaba S.Bus) select a Pulse Width Modulation (PWM) vacant port or use a PWM conversion harness. The ESC relies on pulse width modulation (PWM) to determine its desired position.

ESC PROGRAMMING

INITIAL CALIBRATION

The Electronic Speed Control (ESC) is preprogrammed. However, the throttle range must be recalibrated as different transmitters have different throttle ranges. The procedure is simple.

Throttle Range Setting: (Throttle range should be reset when a new transmitter is being used)

• Turn on the transmitter, move the throttle stick to full throttle position.
• Turn on receiver/ESC power and wait for about 2 seconds.
• Two beeps “Beep-Beep” should be emitted indicating the full throttle range position has been correctly confirmed.
• Immediately move the throttle stick and trim tab to the lowest position. A single “Beep“ tone should be emitted, indicating the lowest throttle range is correctly confirmed.

TRANSMITTER PROGRAMMING

Detailed program sequences are beyond the scope of this document. Specific transmitter programming sequence video instructions are available on YouTube for both Futaba and Spektrum at:

MIXING THROTTLE WITH YOUR SMOKE CHANNEL

The pump has an adjustable flow rate set via the transmitter through a program mix. By mixing the designated Aux channel (slave) to the Throttle channel (master), the throttle position determines the fluid flow rate. In this example, the throttle is used to control the pump output volume and the gear switch is used to turn the pump on/off.
With the gear switch in the on position, the smoke system is activated. Once activated, the smoke system turns on once the throttle stick is advanced beyond a set point (In Value). Fluid flow is regulated via an exponential output curve to smooth the response. Fluid flow will increase as the throttle is advanced and decrease as throttle is lowered. Depending on the sophistication of your radio, the optimal flow rate can be set to achieve the optimal fluid vaporization throughout the full range of throttle positions.
Initial Radio Settings: Sub trim set to Zero. Servo Reverse set to Normal. ATV set to 100%. Program Mix – Throttle (master)/Aux1 (slave – Any channel you designate for smoke).

• Assign switch to PMix function.
• In “off” position Mix should be set to -100 across input from 0 (throttle stick at low) to 100 (throttle stick at high).
• In “on” position Mix should be set to -100 from 0 (throttle stick at low) to first point1 set at +15 (ensures pump will not run at idle)
• Point2 (throttle stick at high) set at +50 (decrease this number to decrease the pump output and inversely increase output up to +100 to increase pump output).
  • To fine-tune the delivery of fluid based upon the throttle setting, any number of additional points can be set between the initial Point1 (pump start) and Point2 (pump full output).

TIP: It is best to start at a very low pump output value e.g. +30. The key to complete fluid vaporization is to deliver only what the heat of the muffler(s) can vaporize. Too much fluid; you end up with an oily mess on your airframe.

NORMAL STARTUP PROCEDURE

• Turn on the transmitter, move the throttle stick to bottom throttle position.
• Turn on receiver power and a single beep is emitted indicating the power input is OK.
• The pump is now ready for use.
