Gloster Gladiator fuel tank position

[Russ P]

I'm currently building a Gloster Gladiator and trying to work out the best position for the fuel tank.

It will only fit between the firewall and F2 in a transverse position or behind F2 which will place it on the C of G.

The question is is it ok for the tank to be transverse or if behind F2 will the longer fuel run be ok?

All depends how aerobatic you are with the model, transverse would be better than a long run IMO.

Why don't you cut a hole in F2 to allow the tank to fit longitudinally with the neck just approaching F1?

I have to agree with Alan. Its only wood after all!

Fitting the tank transverse way cause issues as large angles of bank can leave the clunk high and dry causing the engine to stop

The only problem with cutting F2 is that the u/c and carbine are secured to it and I'm afraid of weakening it.

Double up what remains?

A hole transfers stress around it Russ, and this can reduce the force upon the part

Where a flat plate can crack across

The tank is more important, so cut the required amount

Then line the outer of F2 with triangle stock as is popular with builders

Thanks for the replies. I'll go with cutting out F2.

If you use a round tank, then use a hole saw to cut the clearance hole in F2. The lack of sharp corners will avoid raising stresses in the remaining parts of F2.

If you use a rectangular tank then make the rectangular cut-out by drilling holes in each corner of the cut-out in F2 and then fretsaw between the holes. The radiused corners of the cut-out will again prevent stress being raised in F2.
