An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

The R-4 had a single Warner R-550 piston-engine that was capable of propelling it at speeds of up to 120 kilometers per hour. However, it was later discovered in the field that this was slightly underpowered, which could cause some problems in the field, especially in the critical time it took to recover lost personnel. The R-4 required only a single pilot to operate, though could carry another passenger. The operational range of the craft was around 370 kilometers and a service ceiling of 2,340 meters.

  • The R-4 had a single Warner R-550 piston-engine that was capable of propelling it at speeds of up to 120 kilometers per hour. However, it was later discovered in the field that this was slightly underpowered, which could cause some problems in the field, especially in the critical time it took to recover lost personnel. The R-4 required only a single pilot to operate, though could carry another passenger. The operational range of the craft was around 370 kilometers and a service ceiling of 2,340 meters. The total weight of the R-4 was around 952 kilograms with a total length of 14.7 meters. Rotor diameter meanwhile was 11.6 meters. The reliability of the R-4 was good enough for operational service, though the craft did experience some troubles in the CBI theater where it initially served, particularly the humidity caused by the jungle conditions, which made the Warner engine struggle.
