You thought she thought you were done. In reality SHE KNOWS! (But she'll still say "I thought you said you were done!")

Dave, your not out to lunch at all with the velcro idea. I use velcro to hold all my tanks in place, even in my larger models. Only difference is I use a large piece of velcro, one side is like tape with glue, just remove the paper and stick it to the bottom of the tank. Then use the opposite piece of velcro to stick down to the tank platform. First I use ca on the wood of the platform to assure the velcro stick very well.

I then I make a strap of velcro and wrap it around the whole tank and the platform to hold the whole assembly securely in place. If you still want to pack a bit of foam in there then thats fine too but I have never found the need to do that.

The velcro holds extremely well and allows easy removal of the whole assembly if need be in future. This assembly absorbes vibration very well too, so no tank foaming!

Quick and easy method of mounting a tank and has always worked great for me!

Thanks for all the help guys.. It seems like the velcro way is the method I'm leaning too..

I hope to be done working on the wings in the next few nights so I'll be able to move onto mounting the tanks and finishing things off on the fuse..

Thanks again.

I'll add my $.02. Whatever method you use using an adhesive, make sure it will hold good in the presence of oil. You will likely be using Wildcat 5% (with 23% OIL) and there WILL BE oil eventually in this area. As in another recent listing, the writer said to do it right the first time, because the second time is going to take a lot longer, especially with oil soaked wood.
When I scratch built a DF, I used an existing former & added another light weight former. I cut holes out of these formers about 1/4"-3/8" larger than the tank. I then installed pieces of fuel tubing around the perimeter, slid the tank into these formers & lightly silicone glued the tank. It is still possible to remove them for tubing changes.
I soon learned on this plane to make every part serve 2 purposes to keep weight down. In this case the additional formers increased rigidity & held the saddle tanks.
no such thing as too fast!

I've had pretty good luck fixing tanks in place with silicone. I haven't experienced fuel foaming that I know of, but I'm sure cured silicone has just about zero dampening effect. I do recall reading someplace that the gases coming off curing silicon attack electronics though, so I'm careful to let it cure a long time, at least until I can't smell that nasty toxic smell, before installing receiver and servos. Sorry to be so vague....I don't remember where I read that caution. -Mike
