About this Plan

Maximus. Half-A competition power model.

Quote: "America's Top Modeler Reveals Design Details of Winning 'Maximus' F/F.

Maximus was designed as a high performance contest model that will pat-tern easily and he extremely consistent. With its thrust line half way up the pylon, Maximus has a spiral climb like conventional low thrust model. This is achieved because the center of gravity is located on the thrust line and the center of drag is slightly above thrust line. Because of this arrangement the transition from power is always good, regardless of the position of the model when the engine stops. The airfoil, thin to allow the model as much as possible speed under power, has undercamber to support a good glide.

Maximus flies equally well in wind as in calm air. This was proven at the eastern FAI semi-finals in New Jersey, where the wind was blowing 25 mph. Both of my FAI Maximus flew very good in the wind but were lost; however, I placed 3rd with only 8 of 10 flights.

At the King Orange International meet last December it did 3 maxes in A and B. At two local meets the B did two more sets of maxes and the 1/2A another, then at the 1960 Nationals the 1/2A did 28 min, the B 14 min. Recently a new 1/2A Maximus with only 4 flights after being built did 3 maxes on its 5th, 6th, and 7th flights and the same day my FAI Maximus did S maxes and a 6th flight of 5:52. Does this sound interesting? Clear off your work bench and get ready to build three sizes of a design that will give you a great deal of satisfaction and put you on the winners list.

Fuselage Construction. Use medium hard balsa throughout the fuselage which is built around the pylon. In the 1/2A, the pylon is a piece of 3/16 sheet with the grain running vertically. In the FAI and B the pylon is laminated on the outside with the grain running cordwise. The doublers and fuselage sides are then cemented to the pylon and the bulkheads are inserted. Next cement in the top and bottom pieces, wing and stabilizer platforms. The triangular wedges are made by splitting a square stringer of the appropriate size from corner to corner and bevelling the ends.

The firewall is cemented on the pylon in a notch cut so it will be flush with the front of the pylon. The nacelle is carved from a block of medium balsa and hollowed to hold the gas tank and cemented on behind the firewall... "
