If you are going to try to fit the Sullivan 6 oz. tank, get the flexible one. It will let you squeeze the "overflow vent bubble" along the fuselage side. As far as length, that's going to be tight, too. My Vectarf has some major nose mods (bulkhead moved forward, etc.) but it looks like from where the bulkhead used to be, you would have to get the neck and tubes thru it. A slant tank might help? I am running the Sullivan 4 oz. RST but so far have been using the Evo .36 and OS .35FX. One of our club members has just started flying a Vectarf with an OS .46LA (he won't run anything else....) so I could ask him what he's got for a tank if that helps.
To Geoff's and Dan's comments on doctoring fuel with acetone for range extension--and speedway:

There are tracks at Costa Mesa, Perris, Bakersfield and Ventura here in SoCal.
There is a difference between Speedway racing and typical flat track racing. The biggest difference is that Speedway bikes are very light weight, have no brakes what so ever, are a purpose built bike with a single cylinder engine around 500cc's, single speed transmission and dry clutch. They often burn straight nitro methane. Wheels and tires are much thinner than what are seen on those in the picture that the link take you to. Races are usually four lap sprint races that can be quite exciting. Slowing the bikes down for the turns is accomplished by pitching the bike sideways and controlling the speed and direction that the bike is going with the throttle and steering. Speedway is very big in Europe where they can draw crowds approaching 10 to 20,000 people. These bikes mostly race on cinder tracks. Truly a matter of turning right to go left! Flat track is much the same, but bikes are heavier, multi speed transmission, bigger tires with rear brakes, and race on tracks ranging from 1/4 mile up to one mile ovals. Riders usually wear a steel skid shoe on their left boot to help with guiding and steering the bike in the turns, especially on short tracks. I have seen some of the top riders on mile tracks that are well groomed and prepared, manage to broad slide their bikes through the turns and not put their left foot down, and doing so can really push their speed average up considerably, near the 100mph range. An off shoot of that is what is called TT, and is on a shorter track, anywhere from 1/5 to 1/2 mile long that also has a right turn or two in it along with a shallow jump. One of the most prestigious and longest running dirt track races in the country is the Peoria TT held at a club track near Peoria, Il. It has been held for something like 75 years or more. For a good movie that explains these with some fantastic video and camera work, you MUST see the classic "On Any Sunday" by Bruce Brown. The follow up movie follows the pursuit of a world championship in Speedway by Bruce Penhall, who cut his teeth racing motorcycles in southern California.
