Safety net repair

by Had Robinson

If you must replace your safety net, you will receive the new net only partially assembled.  This means you will have to measure the line lengths of the old net (if you have one) so you can cut the new lines the correct lengths.  Here are some dimensions that will help the process.  Use double half hitches for knots and secure them with Superglue.  Do not use the glue until your net is completely assembled on the paramotor as you may need to make some adjustments in the line lengths.  You can mark the dimensions on the lines with a black marker or Liquid Paper, as appropriate.

Here is how to string the safety net.  It is critical that the net not have holes big enough to get your hand through it and that the net is tight enough so that a quick slap of the net with your hand will not bring it close to the propeller.  The dangerous part of a propeller are the tips.  This is where the netting is critical.  Other parts of a propeller can get tangled in hair and clothing and draw the pilot in to the center – also not a pleasant experience.

The end of the tension string can have either a small karabiner or a ring, depending on when the netting was made.  Use what came in the kit.

Note: complete the task in figure 1 below before installing the line going around the inside of the netting.

Inner circumferential line length  323 cm (127") – The approximate total length of the line going around the inner circumference of the netting WITH ALL KNOTS.  The dimension is from one end of the screw type karabiner/ring to the other.  When Miniplane sends a replacement line it is about 20% longer than necessary.

1. Put a ring on the line at least 24 cm from the end (see figure 2).  This allows for the karabiner and the amount of line needed to tie a know.

2. Put the ring on the hook on the frame (barely visible to the right in figure 2) that is opposite where the line enters the net.  The line will go underneath the gas tank, through the two rings on the net on the opposite side, through the netting around the entire cage, and finally through the two rings on the net at the other end.

3.Put a ring on the opposite hook with the end of the line going through the ring and pull the line snug.  While snugging up the line, work the netting around the circumference at the same time to take up the slack.  You should just be able to remove the ring from the hook without too much force.  Knot the end of the line where it goes around the ring on the hook.

4. Put a karabiner on the hook.  Take the end of the line from the ring and wrap it twice around the line where it goes through the two rings.  Put the end of the line through karabiner and pull on the line to get things tight.  Make a knot at the karabiner.

5. Do the same for the other side with the other karabiner.  Work the knots to make the netting tight everywhere.  The line is tightened over time by unhooking the karabiner and wrapping that line around the line at the two rings.  This pulls the inside lower portion of the net towards the frame, tightening it.

6. When done and everything is adjusted, use Superglue to permanently fix the knots.

Figure 1: 50 cm (20") – Total length of the line to make the double looped lines which tension the net fabric on the fiberglass rods.  This dimension is before any knots are made in the line.  Make the first overhand knot in the double loop at a point so that the double looped line pulls the net fabric enough to completely cover the fiberglass rod and up to the frame.  Put the second overhand knot in the end of the doubled line AFTER the first knot is made and adjusted so that it is easier to attach the doubled line to the rivet on the frame.

Figure 2: 18 cm (7") – Approximate distance between the karabiner and the first ring on the long line that stretches the inside circumference of the net.

Figure 3: 21 cm (8.25") – The distance from the line sewn on the end of the net to the ring.  This ring should already be attached but the knot typically is not secured with Superglue.
