BackPack FT Spitfire

Do you know that moment when you see a great looking plane, think that it flies just well but don´t want to buy it because it´s too big for transport and storage? On this point, you should build the FT Spitfire, surely in a BackPack Version!

All Parts are less than 80 cm long, perfect for BackPack transportation and it still flies like a true Spitfire, maybe even better.

Here, you can see the final removable wingtip. 2 symmetrical parts would have been difficult to build due to the V shape of the wing.

All you need are small 2mm Carbon spars and 2mm aluminium pipes  for holding the construction. First, cut them in lengh, 10cm on each side of the cut should be just right. Then, take a bit of hot glue an secure the aluminium parts on your plane. One on the edge and one directly behind the spar are giving it a nice strengh.

On the other side (now the side of the cut-off wingtip due to save some weight), glue in the carbon spars, already sticking in the aluminium on the other side to line them up. Only use a bit of glue to be able to change something if it does not fit right. The best way is to do all of these steps before folding over your airfoil when building. This way, you can now cut your wing in half but try to be as accurate as possible.

When everything works as the way you want it to, use more glue to fix it nicely. Glue the spars and the pipes up to the very edge of each spot to prevent jiggling of your wingtip.

Now, glue in a servo extension to plug in your servo at the field. Also you can tighten a magnet (you have to use a very strong one or at best several of them) to secure the wing from sliding off.

If you don´t want to risk your plane, use some tape on the bottom to fix it. The big strap sticks to the plane to protect your painting, the upper and smaller ones can be removed after flying.

Finally, leave your car at home, look for a BackPack and go to the flying field by bike or by foot :)
