After doing the mods to the nacelles I made a facia out of 3/32
balsa to put over the outter side to both add some strenght and
make it look better by no chance of any work showing thru the
covering.. While working on the modified nacelles the original
balsa facia was sanded rather thin so adding a new facia over
the original one that is now a lot thinner will strenghten some..
Thin CA could have been used as it would have soaked into both
pieces of wood however I elected to use Titebond even tho it
takes longer to dry.. This was done as the Titebond is every bit
as strong as CA in this application plus allows for a little flex, not
to mention less cost.. There is no weight difference..

As can be seen with the outter facia there is no chance of any
work showing after it is covered...
Then we have a pic of the finished nacelle with the 10oz
fuel tank installed... Yes, the rubber bands stay on fuel tank..
Additionally there will be a piece of soft foam on top of tank
to insure it stays put as the nacelle cover is rounded and could
allow fuel tank to move around..
