Ft Arrow Spear Conversion

So a while ago I built a 120% mini arrow, which is fairly close in size to the FT Spear. It's a great flying plane but as arrow owners would understand, there isn't a lot of strength in the pod keeping the two wing halves supported, and they tend to get a spongy feeling. I crashed recently and messed up the nose and electronics pod. I decided that as the spear is based off the arrow, I might put a spear fuselage with its great box spars and strong box in the arrow. I might move the pod back a little to allow more batteries/gear so I can make this more of a longer range fpv platform. This mod would probably work fine with the normal sized arrow, just make sure the fuse is deep enough for the batteries you want to install.

All parts plans printed off and cut out. I printed the plans at 85% as it is close to the depth of the existing pod. In hindsight I should have matched the width of the pod to the width of the prop cutout at the back but I can fill the gaps with foam.

This will be a great project! I can't to see how it turns out!!
Do you plan on adding a paint scheme once you finish the modifications?
Yes, I think it deserves a paint job after what I put it through haha. Not sure of a scheme yet but I might experiment with stencil patterns like flite test did with theirs

Let the teardown begin! Removing the old pod proved fairly easy. Cut the nose flat like the spear and I'm ready to begin the rebuild. I also added the tape across the back like the spear for added support

Threw some white on the other wing. I'm clearly still learning about painting, the foamboard stencil let in a fair bit of drift paint, a more flexible plastic would probably be better but I'm not too worried. I might just use blue scotch tape when I paint my other "true" spear.
