I am the "Peter Principle", i have a Saito .40/uhp nva and 3 1/2 oz. metal uniflow tank and not enough length to fit them in. WHAT DO I DO?? I need about 3/8" in length. DO i cut into the LE of the wing, and if so how do i brace up around the cut? What else can i do? Please help??? Thanks RON.

Thanks Bob, will look for a Hays 3oz. plastic. Since this is a twin, putting tank in fuse, makes for a long draw to the engine. I need to make a 3/8"deep cut by 2 1/16" wide in wing. Wing ribs are notch for 1/4x1/4 stringer. Ron

Ya I was thinking Profile.. Never seen an LA Heat so maybe should have kept my fingers shut.. Picture?

Roger sent me a picture from the Truck thread.. Boy was I way off base. Sorry to say you may have a HUGE problem. My Saito 40 uses almost 4 full ounces for the pattern but I am running 20% nitro.. If not flying competitively 3 to 3 1/2 ounces will be fine but afraid it might not be enough for the full pattern.

So OK you are going to have to cut into the wing, just try to build a box with enough structure to make up for what you cut out of the wing. A hard tank is going to be your only option but I would seriously thnk about replumbing to clunk tanks. There was a thread on SSW a while back on this subject will see if I can find it...

  WOW, thanks for the feed back. THe drawing is great, I will look into getting some clunk/metal tanks made, i don,t solder well enough. I think i can box in enough strength, then triple layer with 00 silkspan cut in circles to reenforce. Am i missing anything here? A big plane, don't want the wing to fold. Bob i didn't give enough info at first, should have said twin, my bad. Ron

 Frank, I am going to use Tom Morris 4oz. piped for uniflow to start, may change to pressure per Dallas Tx. flyers. Using the Saito .40's i am going to cut back into the wing to the 1/4" spars. Am i in over my head? The tanks are plastic. Ron.
