Explore aviation engineering with the 470-piece Ugears R-5 Radial Engine! A USB-C powered rotary radial engine with authentic cylinder firing order.

R-5 Aircraft Engine - USB-C Powered 5-Cylinder Radial Aviation Model

Feel the pulse of aviation history with the R-5 Aircraft Engine by Ugears. Styled after legendary 1930s five-cylinder Kinner radial aircraft engines that powered pioneering flight trainers, this 470-piece technical puzzle dissects real engine combustion cycles. Driven by an integrated electric motor via USB-C, this educational showcase reveals genuine firing sequences with breathtaking mechanical clarity.

Aviation Kinematics & Pushrod Synchronization

A hands-on, operational masterclass in reciprocating radial engine design:

  • Authentic Firing Order: All 5 pistons drive the counterweighted crankshaft in the exact 1-3-5-2-4 firing sequence with timed overhead valve rockers.
  • Hybrid Timber & Metal Internals: Combines precision laser-cut birch components with genuine metal pushrods and heavy-duty valve compression springs.
  • USB-C Drive with Slip Clutch: Powered via a base-mounted electric motor with a disengaging slip-clutch propeller to safeguard fingers and gears against jamming.

Technical Specifications

  • Engine Type: Motorized USB-C powered 5-cylinder radial aircraft engine.
  • Dimensions: 22 x 24.5 x 14.5 cm.
  • Materials: Birch composite wood, metal springs, electric motor, and circuit components.
