Engine 4C:

  • Plug-in struts and pre-bent aluminum cabanes help to speed up the assembly process
  • The wings feature sturdy D-tube construction and pre-shaped and notched leading and trailing edges
  • A fully symmetrical airfoil delivers intense aerobatics, yet is stable enough for the sport pilot as well
  • The wings remove easily for trouble-free transport to the field
  • The fuse and wings are sheeted in balsa for easier covering
  • An ABS cowl and wheel pants, along with a clear butyrate canopy, are all precision-formed to recreate the scale lines of the full-size plane

It's one of the most storied aerobatic performers ever — and now it makes its .40-size R/C debut in a stylish sport-scale kit! Just like its full-size counterpart, the Great Planes Ultimate 40 Bipe is capable of outrageous stunts, but also shows a docile side that the sport pilot can enjoy. Advanced CAD engineering promises that this will be a model that is as much a pleasure to assemble as it is to fly, and at a price that those bigger Ultimate Bipes can't compete with.

By positioning pushrods between the ailerons, the Ultimate 40 Bipe requires only one servo for 4 ailerons.

The included adjustable engine mount adapts the kit for several engine sizes; smaller engine sizes will fit entirely inside the cowl, preserving the model's scale lines.

Requires a 4 channel radio with 4 servos and a 2-C .40 to .46 or a 4-C .48 - .70 engine.

  The Great Planes Ultimate 40 Bipe is Capable of Outrageous Stunts, But Also
