    Melvin,

    I've been designing and developing automotive fuel systems for years. We use Viton for seals and hoses inside gas tanks because it will last indefinitely in gasoline, kerosene or diesel....

    If your tanks are balooning it's because you are putting fuel in faster than the air in the tanks can vent. How many tanks do you have and how are they plumbed?

    Trent,

    See my post #3292. I did mine similar to mach1. I laid 1/8" balsa over the top of the wings. The sides of the inlets are 1/8" lite ply covered with 3/32" balsa, and the tops are 1/8"...

    I run 5% DTE Lite in everything. My Jet Central calls for 2.5% or 5% if using DTE Lite. My Wren 54 calls for 3%, and my Jets Munt engines call for 4%. I've been doing this for several years with...

    I also need one. Dreamworks is out of stock, and Xicoy makes them by special order only.

    If there's enough of a demand perhaps Todd will order a batch.

    Thanks, Bruce and Mark. I've balanced it to about 6.25" for the first flights, and will adjust from there as Bruce suggests. It took two oversized batteries plus 8 oz. of lead in the nose, so I'm...
