Getting my Reactor ready for springtime. Saw something a little confusing to me concerning fuel tank placement........gas or glow ?

I'm using a DLE 55 gasser. On page 23 of the manual (fig. 33 on top left) it shows the tank placement mounted rearward about 8-10 inches from the firewall. Velcro is used to retain the tank. This fuel tank placement is listed under the gas powered engine section.

On page 25 (fig. 17 right column, center) it shows the tank placement in the conventional area immediately behind the firewall. The tank is retained using rubber bands. This fuel tank placement is listed under the glow powered engine section.

Can I really place my tank that far rearward as shown with the gas powered section ? If I can, this has got to be good because CG position should not drastically change as the tank runs empty.

Guess I'm just used to mounting all of my tanks immediately behind the firewall.

Are you fellah's finding this particular plane to be nose-heavy or tail-heavy when using gas engines ?

Any help will be appreciated.

Thanks,
Joe M.
