Default How to secure fuel tank?

How do you secure the fuel tank in a DPS? It says to secure it to the firewall.

I was thinking of a twist tie around the tank, accessible from underneath.

Default RE: How to secure fuel tank?

The way I secure my tanks is I buy a cheap mouse pad from wal-mart and wrap it around the tank so it is snug inside the gutter pipe and to keep it from moving back I use a piece of flat aluminum, set the tank on top of it ,drill a hole in one end and secure it with my bottom firewall screw and bend a 90 degree behind the tank. It won't move. I also cut a vertical slot in the gutter pipe about the middle of the tank so that I can see my fuel level. Hope this helps.

I found some cheap sponges in the local hardware store, just cut it up and packed it around the tank, doesn't budge

And funnily enough, it also worked on my balsa planes[X(]

How do you secure anything in a DPS? ZIP-TIES!

Seriously, I just do what others have mentioned. Wrap enough foam around the tank that it can't move much. Generally, the firewall keeps it from moving forward, and either the wing dowels or the block for the landing gear keeps it from moving backwards.

Great advice guys. Thanks.

I HOPE the firewall keeps the tank from sliding forward. If it doesn't, I've got bigger problems! Speaking of which, those 4 screws keep the firewall from falling out the front of the fuse? That one makes me a little nervous.

WhiteKnuckles:

I wouldn't worry about only 4 screws holding in the firewall. The way I see it the screws will tear through the fuse in the event of a hard enough crash that could damage your motor if the firewall stayed planted in the fuse (kind of like a breakaway motor mount).

Build it and just fly the thing....if it wasn't a good way to mount the firewall why would it be in the build plans.

I have to agree with Maddd_Maxx on that. Planted my Spadet almost to the wing last year. The engine, mount and firewall (with four screws still in tact) came free of the gutterpipe as she was drilling for oil.
