tank
Category: Fuel System
This is the Moeller tank supplied with the kit from Aerodrome Aeroplanes. It is a 12 gallon poly tank with a float indicator mounted in a 1 1/2" dia. hole.
Discussion with Robert Baslee indicates a cork float with a wire would be the easest thing to do. The existing float gage and indicator will be removed and replaced with a new plug and extended wire. It will need to be marked at the 8 gallon level since the pilot weight is based on an eight gallon weight of 48 lbs (6 lbs/gal x 8 gallons) and the gross weight of the aircraft. Current Gross weight listed as 561 lbs, empty weight at 343 lbs; therefore, useful load = 561-343=218 lbs. And 218 lbs-48 lbs fuel = 170 lbs for the pilot. Note: An additional 4' of wingspan was added to the kit by the designer, Robert Baslee. This will increase the total empty weight and effectively increase the gross weight. Mr. Baslee did not indicate the new values of gross weight or empty weight.
Decided to fabricate an aluminum tank instead of the plastic tank supplied. Terry Lucas has a source of aluminum material and can do the welding. A mock up of cardboard was made and the initial tank with an interior baffle was test fit. Location inside the frame was confirmed. Plumbing tape strapping will be used to support the tank. Terry will weld on clips to the exterior of the tank to capture any horizontal movement.
Again, after discussion of placement, we have changed the location to a higher position - closer to that shown in the plans. Terry has welded up a new tank that will fit under the turtle deck and above the top set of longerons.
Considering the engine's requirement of having a fuel pump, it was decided to add a 2nd fuel pump to the fuel system. It was added adjacent to the existing pump at the bottom of the fuel tank. Another switch was added so separate operation of the pumps can be realized - the Pilot's Handbook should include the alternating operation of the pumps after each flight.
