Flexifoil Spar Maintenance Ever been flying your Flexifoil and the spar pops apart in mid flight? |
|
|
|
|
| Often the spar may pop apart while it
is in flight, due to the ferrule being a bit loose. The easy fix is just to tape the spars
together. You will need to have 4 pieces of re-inforced tape for each join. Any sort of re-inforced tape will work well.
|
|
| Firstly tape the ferrule to the spar where it is already attached just for extra support. | |
 |
Then cut an 6 inch length of tape and
fold it over 1 1/2 inches so it sticks to itself, creating a 3 inch length of tape which
has no sticky edge to it. Place it lengthways along the ferrule and tape down about
1 inch of it to the ferrule leaving about 2 inches hanging over as a "flap" as
in the photo thereby creating a flap. This setup will remain on the spar permanently.
|
| Next cut a length of tape 4-5 inches
long. Fold back each end about 1/4 of an inch onto itself as this piece of tape will be
used again and again. The folding back will enable you to peel it off the ferrule easily
after each use.
|
|
 |
Insert the spar into the ferrule and tape down the flap you created. This simple fix will stop the spar popping apart in mid flight and will last for months even years. We have had this same piece of tape on one of our Flexis for about 2 years, and it is just as sticky and good as the day it was put on. (It just looks a bit naff now from use). |
