Hey gang, I'm one of the new guys. I'm taking the bold action of installing Steve Winder's crosslinked poly gas tanks into my Kitfox Seven to avoid the evils of alcoholic gas tank degeneration (if it really exists). I've received the plastic tanks and cut the old fiberglass tanks out of my wing. Wasn't near as bad as I had anticipated. "Airedale" Steve has been very helpful. He does respond to e-mail. The new tanks look very good. Anyway, within the next few days I hope to install the tanks into one wing and will be able to give ground level info if anyone is interested. Cost per wing $500. There's more info (at) WingTanks.com than was originally posted there. Have really enjoyed the dialogue here on the list.

As the tanks are load-bearing structurally, how do you know the new tanks will do that job?

Bob, When I pulled the factory-installed tanks (Sky Star '94) out of a Series 5 factory-built wing, I noticed that 90% of the adhesive designed to bond the tank to the spars was cured without any contact with the spar. This was because of the large gap between the tank's front and rear surfaces and the spar surfaces. With almost no adhesive bond, how strong could that be? It was mostly just the small tank flanges glued to the top surface of the spar (most of which was also loose). The fabric is glued down to the top of the tank, but how strong could that be? Anyway, the new tanks connect with small aluminum tubes connected between the spars, plywood over and under the tanks - glued all the way around, and expanding foam filling the voids. I've built houses, surfboards, worked on boat construction, etc. And all I can say is that this APPEARS that it will be at least as strong as what was there. And that's just an opinion, I'm not an aero engineer. As you say, info on the net is worth what you pay. But ours is an experimental hobby by nature. Steve of "WingTanks.com" says that other experimentals are flying with this type of tank and similar wing construction - I believe he said "Just Aircraft" are using this type of tank.

Hi Bob. Would you please put your full name, approximate location, 

aircraft and engine type, and build / flying status in your 

signature? Mike and I are trying to make the place a little more 

friendly and the information helps people get to know each other a 

little better.



Thanks,

Just for the record..



	To the best of my knowledge SkyStar never installed fuel tanks in other

then factory demonstrators.. factory built wings did not include fuel tank

installation.



The install is very different in the other aircraft and usually results in

much less fuel capapcity.
