Last night as I was running my CN MU-2 powered F-7, I noticed that 1 of the 2 fuel tank posts was broken. Although the second one can hold the tank in by itself, I'd like to fix the broken post before the other one snaps. Does anyone has any ideas for fixing this? I'm thinking super glue, but I'm wondering if there is anything better to use on plastic.
I've lost 3 other CN F-7's to fuel tank problems, which I would like to fix. Here are the problems...if any one has any suggestions for fixing them let me know. (All of these are mounted on single posts btw).
The first one has the fuel tank, but the post has completely snapped off and is stuck inside the tank. Basically there is nothing to mount it on.
The second one has the fuel tank, and most of the post, but the top has cracked off and the remainder of the screw is stuck in the post. The tank stays in, but is not very secure without the screw.
The third one is missing its fuel tank (post is fine)...I'll have to find a new one.

| Cheez-- Try some Walthers GOO--it will allow the tank to hold and you can also remove tank again if needed with minimal mess and ease where as Super glue may do more damage if you try to remove after gluing or may not be able to remove at all.

Hello Cheez, I just repaired one of these CN single posts that I got from ebay. I used for the first time something called "Goop Household contact adhesive and sealeant". Got it at Home Hardware.
So far so good. This one had the screw still in the broken post, so I removed the screw, glued the post back, waited 24 hrs. and snugged screw back in "just enough".

On the units where the post is gone, a sparing application of Walthers Goo as Brian suggested, or even contact cement or rubber cement, will work. Put a little bit on the cides of the tank, and clamp the shell to it with rubber bands until it cures.
Be careful not to use too much GOO though because it will warp plastic if too much is used. But it is pretty amazingly strong stuff.
One the one where the tank is missing, you could try making your own...

I made a tank frm wood and plastic.
I cut out the notches in the shell skirt and made a plastic plate with tabs that fit into the notches then glued a carved block of wood on the bottom. Then I glued weights to the top of the plastic.
On the ones with the weights in tact, you could drill some holes through the notches in the skirts and into the weight, then glue small pins in the weight that will fit into the holes in the shell.
