Hey Folks,

Relating to my current 1961 C185 complete IRAN, update and rebuild. I have found (and am planning on plumbing for) a Javelin fuselage tank. I am getting basically the tank only and would very much appreciate any leads on obtaining copies of the original installation drawings, operating instructions, early STC or 337 data, basically ANY papers that can help with the install and approval. I will be happy to pay for the trouble of copying etc. etc. I know it isn't rocket surgery, but reinventing the wheel usually isn't the best option!
I am hoping someone in the forum has the setup or knows someone at their field who does.
Again I know it's a PITA (I have done similar "chores" for folks) but I am happy to compensate for the time and trouble.

Many thanks to all.

I almost went this route for extra fuel a while back but stop when i realized how much vertical access would be lost through the baggage door however that was in a 170B maybe the placement in a 185 is further aft, behind the baggage door

It is a trade off I know... I am planning on making it as easily removable/installable as possible.

I have a Javelin tank in my 180 Lycoming 170B which was installed a couple of owners ago. I would never install one and would not have it if the airplane had not came with it. The major problem as I see it is the installation is limited to 60 pounds in the baggage compartment with 1/2 fuel in the tank and ZERO baggage with full fuel in the tank and requires a placard as such. The International Cessna 170 Assoc. has many discussions regarding the Javelin installation including information on how to contact the son (I believe) of the original manufacturer. The Assoc. also has drawings and instructions in the assoc. members only area. Installation in the 170B is approved on the aircraft type certificate. I am not sure the Javelin tank was ever approved for the 185.

Thanks Tim-
I appreciate the insight, and no I don't think it is STC'd for the 185 but I am CAR 3 and will get it approved. While my far aft baggage is weight limited it still has a lot of cube, I have a very light and flexible seating arrangement allowing various seats to be in or out and a 300+ HP Lycon 550. I also have one of the heavier props, and a forward battery. I want the flexibility for tankering and long north legs. It will installed with removability in mind.... and then I may hate it LOL. You could sell yours in 5 minutes...
I have a note in to the 170 guys, I saw a lot of info that I cant get to, so I joined (I fly a 54 B some also).

Fishhauler, I don't hate the Javelin tank enough to take it out and have used it a couple of times but it does take some planning to use. There are better choices for a 170 and I would spend the money on the Del Air wing tank mod if I was doing a 170 from scratch. But that is me and what works for someone else may not be the same. The Javelin Aux tank transfer line T's into the line from the right fuel tank to the selector and you are not allowed to transfer fuel into the right tank when using the right tank or both. This is to prevent introducing air into the fuel flowing to the engine when the aux tank runs dry. So you have to burn the fuel out of the right tank first, then switch to the left tank while you are refilling the right tank. Transfer is at a rate of 2 1/2 minutes per gallon so it takes 45 minutes to transfer the full 18 gallons. Does your 185 have a left/right/both selector or just the shut off, if just the shut off you may have to install a fuel selector. You will need a transfer pump and a check valve (in transfer line to keep fuel from draining from the wing tank to the aux tank. I have my airplane opened up right now for an annual and am changing the lines (hoses) and will try to get photos tomorrow. Hopefully I can figure out how to post them but no promises (old guy).

ps thank you for joining the 170 assoc, there are a few strong personalities there that sometimes rub the wrong way but the assoc is an
outstanding source of technical information

The wing tank modification would be Plan A for me as well if looking for a permanent solution. For now I'm planning a series of small containers carried in float lockers being installed this winter.

Go to the 180 club website and look for Skywagon_JIm. I sent him a collection of documents regarding the Javelin tanks last year which he said he would make available to others when needed. I think you would find what you need in those docs. If you can't track him down, pm me and I'll put you in contact with him. Keith

Keith, you're suggesting he go find another guy on another site that YOU gave the docs to?

Why not just make them available here?

Because I no longer have them. They went away with the sale of my 170. I could contact the current owner of my 170 for them I suppose but it seemed just as easy to send him to the 180 guy since he is working on a 185. If I recall correctly, I attempted to send them to you as well for posting here but the files may have been screwed up and I don't think you could open them. I made hard copies for the 180 guy... no one could open my digital copies.

My apologies. You did send them to me as attachments. I found them in my inbox. I'll see if I can get them posted today.

Too much juggling and I drop quite a few things.

KG and Z Guys. Thanks a bunch! Great additional stuff. Filling in the blanks. Has anyone seen it installed and 337 for 185 vs 180?

KG as in Murfreesboro MBT in Tenn? I lived on the TN96 grass strip just north or 25 years.
