An amazing new safety restraint device

Product Instructions

Fig 1



Take the Release Assembly (A), rotate the hinged restraints (B) and latch them upright. Push foam protective covers fully down. Caution: When rotating the hinged restraints (B) extra care should be taken to prevent your fingers from being caught.

Place the Release Assembly (A) onto flat ground in your starting area. Ensure the selected ground is suitable for securing the Release Assembly (A) with your chosen fixings.  (For hard concrete type surfaces refer to concrete  fixing instructions Fig 7).

Fig 2



Once positioned, insert your chosen fixings into the two location holes provided on the base of the Release  Assembly (A). It is important that you insert your chosen fixings at a slight angle in the opposite direction to the   thrust of your R/C aeroplane. Use a small claw hammer for this purpose. (Not included).
Caution: Care should be taken when hammering your chosen fixings into the Release Assembly (A) to avoid  damage to the foot pedal.

Fig 3



Loosen the red hand screw fastener located directly in front of the foot pedal. Open the Release Assembly (A) and obtain the required position by placing your R/C aeroplane tail wings directly behind the hinged restraints (2 x B) as   close into the fuselage as possible without obstructing moving parts to your R/C aeroplane. Tighten the red hand screw fastener.

Fig 4



To prevent your R/C aeroplane from moving backwards during starting, insert either two or four of the extension arms (4 x G) into the swing arms attached on each side of the Release Assembly (A).  Ensure the red ends of the extension arms (4 x G) are pushed in until no red is showing.  Place your R/C aeroplane in the Release Assembly (A) ensuring the rudder is in the central position.  Raise and securely latch the two hinged restraints (2 x B).  The distance from the front leading edge of the tail plane to the back of the undercarriage wheel legs, as shown must not exceed 1.3 metres.

Fig 5



Slide the restraint adjusters (2 x F) onto the extension arms to obtain the required restraint position directly behind  the undercarriage or wheel legs. Make sure the restraint adjusters fall forward away from the Release Assembly (A).  The fixing location holes on each of the restraint adjusters (2 x F) can either be faced inwards or outwards, this  will depend on the type of R/C aeroplane.  Slide the undercarriage restraint adjusters (2 x F) along the extension   arms and then pass them beneath the undercarriage.  Select either undercarriage height adjuster (C) or (D) depending    on the height of your undercarriage or wings, and insert them into each undercarriage restraint adjusters (2 x F) ensure the ball springs are inserted into the appropriate location holes.  Make sure the top of the poles, once in the   upright position; do not touch the underside of the fuselage or wings.

Make certain the undercarriage height adjusters (C) or (D) securely restrain the rear sides of the undercarriage wheel sections.  The hinged restraints (2 x B) will need to be in the upright position restraining the rear tail wings when obtaining the correct position prior to tightening the red screw fasteners.  Foam protectors (2 x H) can be cut to size and used if necessary; simply push them onto the selected undercarriage height adjusters (C) or (D) to protect the aeroplane's undercarriage.

Fig 6



Select the tricycle undercarriage attachments (2 x E) and insert them into the undercarriage height adjusters (C) or  (D), the angled end of the tricycle undercarriage attachments (E) can face inwards or outwards to the extension arms  (G).  Slide the undercarriage restraints forward until the tricycle undercarriage attachments (E) are firmly braced  across the rear side of the vertical wheel legs on the R/C aeroplane and then hand tighten the red screw fasteners each side.

Fig 7



Permission must be obtained from an official authorised Club committee member or Safety Officer prior to drilling the hard surface as required.  Then a permanent starting location should be selected for the Airopult.  Place the Release Assembly (A) in the starting location and mark through the two fixing holes. We suggest you use a 10mm masonry drill that should be slightly angled in the opposite direction to the thrust approximately 100mm deep. Use 2 x 8mm x 100mm coach bolts (Not included), loosely insert them through the two location holes in the Release Assembly (A) and into the pre drilled hard surface. Please note: It will not be possible to fix the undercarriage restraint adjusters (2 x F) into position on hard surfaces, as these will need to be adjusted dependent upon the selected R/C aeroplane.  Please refer to Fig 11 ensuring the red ends of the extension arms (G) are firmly pushed together during use. If in doubt, please refer to our website. 

Fig 8



Once satisfied that your R/C aeroplane is securely held from moving in all directions in the Airopult you are now   ready to safely start your R/C aeroplane without assistance. Should you choose to use a battery operated starting  device, hold the device with two hands and press firmly against the nose cone of your R/C aeroplane.  By using the  Airopult you no longer need to hold the front end of the aeroplane - thereby avoiding the risk of potential lacerations from the propeller.  
IMPORTANT: For safe operation of R/C model aeroplanes, RC Airogrip SL suggest that a radio check of control surface operation is carried out before starting your fuel engine or electric motor and again afterwards paying   particular attention to the fail safe operation. Once started and all pre-flight checks have been carried out, you are ready to release your R/C aeroplane. 

Fig 9



Ensure that your throttle is set to tick-over.  Stand behind the R/C aeroplane and with your foot, slide the red safety  latch on the foot pedal to the right until the green indicator shows. 

Fig 10



Depress the foot pedal fully to the floor until both hinged restraints (2 x B) are released.  Once released remove your foot from the pedal.   You may then take hold of the tail of your R/C aeroplane and push it out of the Airopult  to the take off area.  Should the tail plane of your R/C aeroplane be lower than either undercarriage height adjusters (C), (D) or tricycle undercarriage attachments (E) as the R/C aeroplane passes over them, the height adjusters will  automatically fall, allowing free forward movement.If in doubt, please refer to our website demonstrating  the   Assembly and Operation instructions.

Fig 11



When you are ready to restart your R/C aeroplane, simply reset the two undercarriage restraint adjusters (2 x F) in  the upright position ensuring the red ends on the extension arms (G) are firmly pushed together. If you have not previously nailed the undercarriage restraint adjusters (2 x F) into position. Pull   your R/C aeroplane in reverse centrally  into the Release Assembly (A) making sure the undercarriage or wheel  legs of your R/C aeroplane are firmly supported on the rear side of the undercarriage height adjusters (C), (D) or the tricycle undercarriage attachments (E), if used.  The hinged restraints (2 x B) may now be raised to the upright    latched locking position and the starting procedure can be continued as in Figs 9 and 10.

Fig 12



Dependent upon use particularly on dusty or muddy locations, the Airopult should be regularly inspected and cleaned. Release the outer cover of the foot pedal by simply undoing the four outer 2mm Allen key screw fasteners   that are on the underside of the aluminium base plate of the Release Assembly (A). Examine all moving parts and  clean. Once cleaning has been completed make sure the dust protectors are correctly positioned in the foot   pedal housing assembly unit prior to re-engaging the four 2mm Allen key screw fasteners.

To keep your Airopult in pristine condition especially when used on muddy or dusty type ground surfaces, we suggest using a suitable thin matting which can be nailed down prior to securing your Release Assembly (A).

Should you wish to dispose of your packaging, please ensure that all packaging materials are disposed of in accordance with local environmental regulations.
