I am working on a 1/2a sized electric and would like to be able to slide the battery into the built up wing. What kind of engineering do you think I should do to be able to remove a section of the leading edge or possibly even the spars from one of the bays next to the profile fuse? Would sheeting an extra bay be enough?
Can you elaborate a little on your wing thickness & battery thickness? Here's a couple ideas frim ones I have done:
* Converted a Baby Clown ARF. No room for the pack inside the wing so instead I notched the wing out back to the spars. Added a shear web between the spars and band the battery to the fuse side. It is right on the vertical CG and works great - Hate to find out what will happen in a crash tho!
* Put an in-wing batt box in a Brodak Jr Flite Streak. I had to just barely sand on the inside of the spars so I did not reinforce them directly However for the center section sheeting from the spars forward I used 1/16" basswood instead of balsa. Had to soak it to get the curvature but it worked great. After the wing was assembled I cut out the Leading Edge of the wing and did the final sanding to fit the battery in place.
I have another bird in the to-build pile that will require removing a good size chunk of the 3/16 square (top & bottom) spars. I plan on spanning that gap with a piece of 1/16 ply and using the basswood planking as on the Jr Streak. I may have to plank out 1 bay farther as you suggested too...
