As the next step for your BackPack Spitfire, this is the BackPack FT 3D!
You always wanted to have a small 3D airplane with lots of power, medium size, capable to fly off a 3cell? Furthermore it should be easy to transport and small for storage, but you can´t get this on the market?
Here you can build or even convert your custom fitted FT 3D into a small model with removable wings, a carbon spar for reinforcement and wings that are as stiff or even better than the original ones with balsa. Have you got your foamboard ready to start up? …
As always, take your speedbuildkit or cut the parts yourself. Here in Germany I can´t get ´the real foamboard´and so I´ll be using depron in the following. Use some tape for your bendings and reinforce holes you´ve cut, that works great for me.
You can already start building the fuselage but do not cut the holes for the servos underneath the wings and leave out the front plate above your powerpod. That is going to make working on the plane much easier.
Now, take your wings and glue in the spars. Get a long drinking straw, a little wider than the carbon tubing you want to use. I found an 8mm straw and put a 6mm carbon spar into it.
Make some space in the middle of the spar and glue it in, than score it on the top so that it can crumble when you fold the wings.
Cut the balsa spar in half or take two of them to increase stability. Line it up with the fuselage-connection and glue it in.
Use a small drill to drill a hole in the center of the balsa spar. It´s easier to place the drinking-straw close to the leading edge and then make your connection.
Now, shift you wings into the fuselage and wide the cut holes if needed. If you did everything right, the wings should line up perfectly and be as well as parallel. Take some thick wire of your landing gear and bend it so it connects both holes perfectly. Give it a very little V-shape so that it pulls on both halves when you plug it in. Finally use a file to make the alignment of the wooden spars a little easier.
On the next picture, the power pod is already installed. I cut a small hole into its bottom to get access to the lock system. On the right I fastened a small piece of Velcro. With another piece on the left it secures the hook in its position.
Finally place your servos underneath the wings and connect them to you receiver when you set up your plane.
And there you go! Now fasten the top motor plate and install your prop. I used colored tape for the decales and a ´standard´swappable landing gear. Whenever you want to store it in a small shelf or want to ride flying by bike, wings can be removed in only a few seconds. Enjoy!
As always: Please rate, comment and share. I'd like to hear about your thoughts...
I usually have to carry my planes in a backpack to the place I fly, so your articles make my life a lot easier. :)
I'm also from germany, I found some decent foamboard in an architecture-accesoories shop here in munich. we also started a thread on getting foamboard in germany in the FT Forums, maybe you could post the link to the polish shop there.

thanks for the recommendation, I already had a tendency to the spitfire, but i guess now it's settled :)
I shrunk down the Baby Blender I'm currently building to 75% of the original size, so i guess I'll try that with the spitfire too, so i can reuse the powerpod and it should be even better to transport. But first I have to glue the last parts in place and spraypaint the BB.
and of course maiden it ;)
Where are you from in Germany? maybe we could meet and fly the FT planes together sometime... I'm from Munich btw.

I´m from Celle, close to Hanover and I've already thought about how great it would be to meet and fly with more Flitetest followers ;)
Munich is a little far away but maybe we can make it some day with some kind of german flitetest-member meetup without the FT-crew or so...

German FT Meetup would be awesome... everone brings their FT Models and we throw a lot of foamboard in the air ;)

the Duster (at leas t in the racer version without the big canopy) is the FT plane which looks I like the most. well the racer and the spitfire... i never can decide on that ;)

FT Racer has got similar wings to the Spitfire, so same process here. It´s a little faster though, so you have to pay attention making everything stiff enough. The 'original' V-shapes are made by bent music wire or so and are fixed in a wooden centered-piece in one wing but that might be a little out of place in a plane like this.
Is there finally any way to send private messages, too? This thread is getting a little long and I´m close to being tired of translating ;D

g8 idea.
I have one doubt how to connect the two aileron servos to the receiver?
(I am new to RC)

For connecting the ailerons to the receiver u can use a Y-cable that splits up the signal and gives you two outputs or you can take a computer radio with a second programmable aileron channel. Then there is a little hole in the fuselage and in the Powerpod again to shift the cables through (or just leave the Y-cable hang out the sides, makes connecting easier)

The little fins are called Vortex Generators. They make the air more turbulent and so it sticks to the airfoil in high angles of attack (reduces wing-rock in harriers etc.).

I hope that helps your build... ;)

Your thoughts are right and yes, it just runs over the hook. If the hook's legs are bent long enough, it can't fall out anymore. Works great.
