Review of OK Model Ultimate-E

The instruction manual includes English instructions and pictures of assembly. The instruction and design of the model makes the assembly of the Ultimate-E very easy. All the accessories such as motor mount, aluminium spinner, wheel pants, canopy, cockpit decals, tail wheel, hinges, horns and push rods are all included with the kit. You only require the following items to finish the model:

  • Radio system and servos
  • Tahmazo ER222012 brushless motor or equivalent
  • Speedcontroller for the above motor
  • Propeller (APC 8x6E is recommended for the Tahmazo ER222012)
  • Battery pack (Kokam 3-cells 21000mAH is recommended)
  • Tools such as knife, screw driver, soldering iron etc required for building a ARF model

Setting up the wings for this Ultimate-E is made easy with the design of the structs are each side and in the centre. The blind nuts for the structs and position are pre-determined by the factory and the installation of the top wing is quick and easy.

Battery is position just behind the cowling by way of a removable hatch below the fuselage. You can access the battery easily with this removable hatch and there is no need to remove the wing.

 

Pilot Ultimate-E in the field

Ultimate-E flies very well, even in strong wind condition without much trimming even on the first flight. The model grooves nto the wind very well. The attractive colour scheme makes the Ultimate-E stands out in the air.

The recommended travel on the control surfaces is designed for pattern aerobatics. For those 3D pilots, more travel will be desired.
