Backward Take off

1. Pull up in back start position. Pilot could be holding front risers to assist in Pull up
Now that you are clipped right riser into right carabineer and left into left, you will be facing into the wind. This is the position one would use for a forward start, usually undertaken when little or no wind is present. When wind is present a BACKWARDS start is preferred as one may watch the glider as it inflates. It may also be inflated and dropped back to ground a number of times until a controlled inflation may be undertaken.

2. Pilot stabalises canopy then gets ready to turn around for take-off.
For a reverse pull up, clip in front ways as described. Now turn around to face the glider while at the same time ducking under the respective riser. The risers will now be crossed, in other words what was the right riser when facing forwards is still on your right side, but seems to go to the left side of the glider (remember what seems to be the left side of the glider now is actually the right side. It is only on the left because you have turned around and faced the wing, and while doing so have crossed the risers).

3. Pilot accelerates forward while standing up straight.
Once the wing is inflated above you, and you turn back around, the risers will uncross and one will be back facing forwards again . . Now you are facing the glider there are many ways of pulling the wing up. I find the following easier. With one hand I grasp both A risers which when pulled will pull on the leading edge and allow the wind to enter the cells. Keep pulling and glider will inflate above one's head. One needs to be able to steer the glider as it inflates. This is done with the spare hand using the respective toggle. If the glider is pulling right counter steer with the left hand on the left toggle. (while in the back start position take the toggle that is on your right side to be held in your right hand and visa versa.) While pulling up the glider on the A lines and risers, (which are held together) there is a constant interchange between which hand is pulling on the risers and which is steering.

4. Keep accelerating until the force of the engine enables one to become airborne.
Never jump into the seat.
Should you need to swap, change both risers to the opposite hand and steer on the respective side with that toggle. This must be done early before the wing has dropped too much, else it is difficult to rectify. Once above your head the risers may be released, bearing in mind you may have to go back to them should the wing start to fall back again. Once the wing is above your head it may have a tendency to fly forward and over fly you. If this is allowed the front will collapse and the glider will de elate. To prevent this both toggles are pulled down and the wing will stop flying forward. Take care doing this in the air as it may stall and you will be back on the ground sooner that you think ! Now you can inflate the wing and control it above your head, one needs to turn around and take off against the wind. (remember while you were pulling up the wing you had your back to the wind).

5. Seat yourself by either a foot stirrup or by holding both toggles with one hand and pushing yourself with the other.
Once the wing is stable above your head and not overflying you or dipping to one side, simply let the toggles go, spinning around the correct way. If you turn the wrong way you will find there is a double twist in the risers. As soon as you have turned round and are facing into the wind, the toggles are taken hold of again(left in left hand and visa versa) one might find you have to apply some toggle pressure to prevent the wing from over flying you again. Alternatively move forward to keep the wing above your head and control the wing again. Should you find the wing pulling for example to the right, you will realize you have to counter steer to the left. Tip- remember to move under the problem side simultaneously. If there is little wind over the wind (wind blowing towards you), you will find you will have to move forward at the same time, while moving under the problem side. If not it will simply deflate due to lack of airflow over the top and hence no lift to keep the wing inflated. (By moving forward you are creating an airflow over the wing and hence generating lift).

6. Here is a brief description of a forward start. Clip in as described i.e. facing forwards in the direction of take off, into the wind, left riser into left carabeener . Make sure the pre flight checks are complete and all risers free from the ones behind etc. Start with you hands by your knees, under all the risers. Move them forward between the risers and your legs, while picking up the toggles and un-clipping them on the way. All the risers now will be hanging over your for arms. Reach back over them and take hold of the front risers in the respective hands. (You may also wish to refer to our promotional video where both starts are clearly shown) Remember pulling on the front risers will inflate the leading edge and facilitate inflation. While staying in this position drop you arms back and down. (almost as if someone is trying to bring your straight arms together behind your back while your PALMS ARE FACING FORWARD). Take a step backwards and when ready run forward letting your arms come up over your head as the glider inflates. Keep hold of the front risers with your arms straight until the glider is above your head. Before take off, LET THE FRONT RISERS GO.

7.This is simply to prevent unnecessary pressure on the front risers which may create a front tuck (the leading edge of the glider tucking over and deflating) With a forward start, while flying with power taking a step backwards and applying power to help the forward run certainly benefits the inflation process. Just remember the glider will inflate quickly and if it has the tendency with either forward or back start, remember to apply toggle pressure with both to prevent it over flying. Alternatively keep moving forward to stay in front of the forward moving wing .

8.Both front and back starts become slightly more acquired when a motor is present. (however ground work is your key to successful paramotor flying. Do it with the engine off and get use to walking around with the engine running while not connected to the glider. this will enable you to experience the turning effects associated with motorized paragliding, while at the same time getting use to the noise and thrust behind). I usually strap the accelerator onto my hand and adjusting it to provide easy access to the lever and kill switch. The toggles are then taken up in what is left of the free fingers . Remember placing your hand over the carburetta will flood the engine and stop the engine should the kill mechanism break. This is one of the main reasons I very seldom use one. A second cut out switch mounted on the frame is also a good idea.

正面起傘（Forward Launching a Powered Paraglider ）
在微風或無風的情況下（PERFORMED IN LOW-WIND OR NO-WIND CONDITIONS）
以下圖片為示範正面起傘的方法，這些並不是拿來做訓練教材用，

在飛動力飛行傘之前您必須接受專業的訓練課程

The following pictures demonstrate the "Forward Launch" method, and ARE NOT intended to be used as instructions for training. You should always receive professional instruction before flying a motorized paraglider.


1：After a careful pre-flight inspection of all the equipment, the glider is laid out on the ground so that it can be pulled directly into the wind. The risers (lines) are attached to the caribiners on the pilot's harness. The DK Whisper engine is warmed up and idling. The pilot is concentrating on the wind in his face, the controls in his hands, and the impending lunge forward.  

2： With a hard pulling forward drive, the pilot causes the glider to begin to inflate and rise off the ground.
The glider (canopy) continues to rise up to an overhead position. The pilot may be making slight side-stepping motions to keep the canopy coming up straight and evenly.   

3：The canopy is now directly overhead. The pilot looks upwards and visually checks that the inflation is even, and the lines not tangled. He continues to move forward, and uses a combination of side-step and brake line application to keep the glider flying level. When the decision to "GO" is made, full throttle is applied, and aggressive forward movement continues.  

4：The glider soon begins to develop more lift, and literally pulls the pilot right off the ground. The pilot maintains full directional control by steering with the brake lines. Rate of climb and rate of descent is controlled by the throttle. When comfortably airborne, the pilot sits into the seat and pops down the foot rests for the ultimate LAZ-Z-BOY chair.
