Hi Sid
I hear you but I have not done my final calcs yet, I might not make the
tanks the full span between the spars but I would like to keep them full

and bottom skins.

Dene; Make sure that the airloads don't travel through the full-span box
structure of the tanks, rather than through the box structure of the spars.
Probably would delaminate from the skins over time. Thermal loads also concern

polystyrene foam in a KR wing being dissolved in flight and it is not good

I built in wing tanks per the Diehl plans between the forward and aft spars,
and from the WAF out to the first wing rib. Turned out to be 10.8 gallons
per side. That 21.6 gallons would provide over 6 hours endurance plus
reserve. Way longer than I care to sit in my tiny cockpit for one
Just remembered this one, did it years ago on a special project. Use any
core you wish for front and back half of wing, and last a foam in the center
area. Cover the spars with a releasable covering, (please don't laugh, but
duct tape works really well for this!), lay up the whole wing as per
Hi guys
It is my plan to put full length wing tanks inside my wings between the
spars but because it is common practice here to use polystyrene for a core
and we all know what happens to poly foam when it even smells fuel, I have
