Pack Shapes


		*2 Cell Stick* A simple 2 cell stick is used in many non-R/C applications.

		*4 Cell Flat* This is the most common shape for 4 cell receiver packs. All 4 cells are side by side like fingers on your hand.

		*4 Cell Square* This is the most common shape for 4 cell sailplane receiver packs because of its narrow cross section. However, don't overlook the following two pack shapes.

		*4 Cell "TE"* The "TE" stands for Thermal Eagle which is a sailplane with a very narrow nose cross section. 3 cells are in a triangle and the 4th cell sticks out in front to better fit into the nose of the sailplane.

		*4 Cell, 3 Cell Stick +1* This is another popular sailplane receiver pack shape. If the nose is really long and narrow, this 3 cell stick with the 4th cell along side at one end is the way to go.

		*4 Cell Stick* Made up of 2 sticks of 2 cells each, this can be a very compact shape for some receiver packs. It works particularly well for some small sailplanes because of their fuselage's oval cross section and the inherent physical strength of the pack compared to the two shapes above.

		*5 Cell Flat* This is a popular pack shape for 5 cell receiver packs, particularly for large aircraft.

		*5 Cell Rectangular* This is an alternative to the above if pack length is a problem.

		*6 Cell, 2 Sticks of 3* This shape is popular with many R/C Car applications. It minimizes the amount of wiring on the pack, but it is also very difficult to repair if you have to replace a cell for some reason. We recommend a flat pack unless you really need a stick pack.

		*6 Cell "3x2" or Rectangular* Rectangular packs can be made up with any number of cells. If the pack is simply made up of two rows of cells, one over the other, use the "Rectangular" designation. If the pack has more than two rows of cells, use a description such as 3x3 or 4x3 or 5x5 to describe the pack.

		*7 Cell, "7E"* We didn't know what to call this shape so we simply used an "E" to indicate that there's a cell across the "End" of the pack. This is also a popular R/C Car pack shape.

		*7 Cell Rectangular* This is another popular electric flight pack shape. 3 cells over 4 with the 3 cells sitting in the grooves between the 4 cells. Sometimes described as the cells being stacked like cord wood.

		*7 Cell "TS"* Another electric flight pack shape for thin fuselages. It's like the 8 cell TS pack, but with 1 cell missing.

		*8 Cell "TS"* The "TS" stands for Transmitter Square and it's the most popular transmitter pack shape today. There are other ways of describing it, but if you say "TS," we'll know exactly what you mean.

		*8 Cell Flat* The 8 cell flat pack is used in some transmitter applications. In addition, it is the most popular shape pack for electric flight and can be used for any number of cells arranged in a flat configuration.

		*8 Cell "T91" or 9 Cell, 3 Sticks of 3* The most common use for this shape is in Futaba "G" and "J" 8 cell transmitter packs. Although it looks like a 9 cell pack, Futaba uses a dummy cell rather than a real one in one of the corners. This is shape is also used in some electric flight applications as a flat pack made up of 3 sticks of 3 cells each.

		*12 Cell, 6 Sticks of 2, "3x2" or Rectangular* This pack is similar to the 6 cell Rectangular pack, but instead of being made up of individual cells, it's made up of 2 cell sticks. Any number of cells can be made up this way.
