Description:

Laser-cut balsa kit, 25-class low-wing sport plane “Cavalier”.
The highly precise and clever component construction, made possible by OK Models' extensive expertise in computer-aided design and laser cutting, allows you to assemble a lightweight fuselage with no deviations.
The nostalgic design incorporates the latest aerodynamics and test flight results, and the thin symmetrical airfoil shape allows for exhilarating flight at high speed.
The ELF Retract 30 (electric, no-linkage retracts) can also be installed for retractable legs.
The ELF can be powered by either a 2-cycle 25-class motor or a 500W-class brushless motor such as the Tahmazo ER-252312d.

Suitable for intermediate level users.

< Items required before flight >

This kit does not include undercarriage components such as fixed legs, retractable legs, or tires.

The ELF retracts are the best choice for retractable legs. The veneer retractable leg mounts are designed to fit the ELF retracts.
When using conventional retractable legs or supra retracts with retractable leg servos, modifications to the leg mounts or servo mounts are required.
DURA main gear, etc. are required for fixed leg specifications.
