Here we go again! Justin,Here we go again! Did you not read or learn from the last time you posted a question about the type and grade of wood to use and where to purchase it? Check back in the (recent) archives, and everyone was still saying the same thing. Purchase your wood from AS&S or Wicks. Assemble your aircraft with only aircraft grade materials. NOT from materials purchased at the local hardware store or Home Depot. Mark Jones wrote:Aircraft grade Birch is acceptable and is readily available at Wick's and AS&S. Do not use non aircraft grade Birch plywood for structural building as it does not meet Mil Spec MIL-P-6070B. This spec covers grain, thickness, moisture, tensile strength,glue, bending, torsion and immerson. Justin wrote: I seen Birch Plywood at the Local wood store. Is this ok for airplanes? I know a fellow plane builder in my chapter who is building his plane with Birch but im not sure where he got it. I am no expert in anyway (obvously) on what is acceptable.

Ever Champ, Chief, Cub, etc. ever built had a tank right in front of the intrument panel. Granted, they weren't composite, but they were probably more prone to leak than composites since any little kink in the metal could cause a leak, especially with all the work-hardening due to vibration over the last 60 years. My 1941 Chief had a 12 gallon tank and it never caused any problems. I know, I never crashed it... but it's on the back of the firewall so you might get cold and wet but there's really NOT that great of a chance that you'll be a giant fireball. This is me, ducking back into my foxhole. I do have wingtanks in my KR but I may never use them, I think the 12 gallon header tank will last for as long as I want to sit in it at any one time.
