okhobby, often associated with the OK Hobby Infinite product line, was a Hong Kong/China-oriented hobby brand and online retailer. It operated primarily within the radio-controlled (RC) hobby industry, gaining recognition for electric propulsion equipment. Its products included brushless electric motors, electronic speed controllers (ESCs), batteries, and other RC components. The brand focused on offering relatively inexpensive alternatives to more established hobby brands. Historical RC forums document the company and its products extensively from the late 2000s and early 2010s.1

okhobby became known internationally through the growth of online RC commerce. During the late 2000s and early 2010s, its website, okhobby.com, was discussed on RC forums as a source for relatively inexpensive motors, ESCs and other electronic components. Forum posts from 2010 specifically discuss okhobby’s 160A ESC and 2050KV motor systems, demonstrating that the brand was already selling high-power electric propulsion equipment at the time.

One of the company’s most recognizable product families was Infinite, particularly its brushless motors and electronic speed controllers. Contemporary hobby discussions describe Infinite as a budget-oriented brushless system covering applications from small RC models through larger electric vehicles and aircraft.2

The company did not appear to operate entirely as a conventional vertically integrated manufacturer. Much of its product range was associated with OEM/ODM production in China’s expanding RC electronics industry.

Infinite brushless motors

The okhobby Infinite motor range is probably the part of the brand most familiar to older RC enthusiasts.

In particular, extensive research posted on RC forums identified similarities between okhobby Infinite motors and products associated with SunRay Technology, LiPolice, Pelikan Foxy, Hyperion, Hacker, and other brands.

For example, one documented comparison identified an okhobby Infinite 5045 motor as essentially the same basic motor as corresponding LiPolice and Foxy products, with differences primarily in external housing and branding.

Another historical compilation of SunRay factory specifications lists equivalent motor specifications across SunRay, LiPolice, Pelikan Foxy and okhobby Infinite product lines.

This illustrates a common characteristic of the RC industry at the time: the same underlying OEM design could appear under multiple brands, sometimes with different housings, colors, specifications or marketing.

Typical Infinite motor naming

Infinite motors were generally identified using specifications such as:

• motor/stator dimensions
• number of turns
• KV rating
• weight
• maximum current
• recommended voltage
• intended aircraft size

For example, historical documentation identifies an Infinite A3025-770 alongside equivalent 3025/770KV motors produced through the same OEM ecosystem.

Electronic speed controllers

okhobby also sold Infinite ESCs, including versions intended for both aircraft and other RC applications.

Historical documentation describes Infinite aircraft ESCs ranging from relatively small units to high-current controllers. Some models offered programmable functions such as:

• brake on/off
• battery type
• motor rotation direction
• soft start
• low-voltage cutoff
• timing
• switching frequency
• factory reset
• helicopter governor/RPM control

These functions are documented in historical material concerning the okhobby Infinite ESC programming system.

Interestingly, hobbyist research found substantial similarities between Infinite ESC programming systems and ESCs sold by other companies. This was interpreted as evidence of common OEM manufacturing rather than necessarily indicating that okhobby itself manufactured the electronics.

One of the notable aspects of okhobby’s history is its relationship with the Chinese OEM ecosystem.

The evidence suggests a model broadly like:

OEM factory → produces common motor design → different companies/brands → different housings, specifications and marketing

Consequently, okhobby Infinite should not necessarily be viewed as a manufacturer in the same sense as a company that designs and builds every component itself. This also helps explain why okhobby products could be sold considerably more cheaply than visually similar products from premium RC brands.

okhobby occupied a value/budget-oriented position in the RC market.

Contemporary hobbyists frequently compared okhobby with HobbyKing and other inexpensive sources of RC electronics. A 2011 discussion, for example, describes okhobby as one of the inexpensive options for brushless systems.3

Its appeal was essentially:

reasonable performance + inexpensive pricing + broad availability

rather than:

premium branding + proprietary technology + high-end pricing

This made the company particularly attractive to hobbyists who were building or experimenting with electric RC models and did not want to spend heavily on motors and ESCs.

The historical reputation of okhobby was mixed. Some RC users reported satisfactory experiences with its products, particularly considering their low prices. A 2011 forum discussion describes a buyer using an Infinite 17.5T brushless motor and 100A ESC, praising the quality relative to the price and the shipping experience.4 However, the same discussion also contains a contrasting customer report involving a serious dispute with the retailer. This illustrates that customer experiences were not universally positive.5

Therefore, it would be inaccurate to characterize okhobby simply as either a “good” or “bad” brand. Its historical reputation was more accurately that of a low-cost hobby supplier whose products could offer strong value, while quality control and customer-service experiences could vary.

okhobby is particularly notable because of its position within the interconnected RC OEM market.

Historical comparisons have linked okhobby Infinite motors with products from:

• SunRay Technology
• LiPolice
• Pelikan Foxy
• Hacker
• Hyperion
• Gens Ace
• Turnigy SK3
• Torque
• other smaller RC brands

The exact commercial relationships between these companies are more difficult to establish than the physical similarities between products.

The historical okhobby website and product references are now largely encountered through archived pages, old manuals and RC forum discussions rather than a clearly documented current corporate presence.

This makes okhobby somewhat of a legacy RC brand. Its products can still occasionally appear in discussions about older RC models, particularly when enthusiasts are trying to identify the specifications or OEM origin of an old motor or ESC.

The brand should therefore be distinguished from unrelated companies that currently use the name “OKHOBBY.”

There is an important modern complication regarding the name.

A company called Shanghai Zhanyong Information Technology Co., Ltd. filed a U.S. trademark application for OKHOBBY on May 31, 2023. That trademark was registered on April 29, 2025, under U.S. Registration No. 7,779,633. However, the registered goods are hand-operated kitchen and household tools, including forks, spoons, children’s scissors, fish scoops and vegetable slicers—not RC equipment.

There is currently no reliable evidence establishing that this Shanghai company is the successor of the historical RC okhobby business.

Summary of distinctions

Historical okhobby
→ RC hobby retailer/brand
→ OK Hobby Infinite
→ brushless motors / ESCs
→ prominent in late-2000s/early-2010s RC market
→ products associated with Chinese OEM ecosystem

Modern OKHOBBY trademark
→ Shanghai Zhanyong Information Technology Co., Ltd.
→ registered in 2025
→ kitchen/hand tools
→ apparently unrelated to the historical RC company.7

okhobby’s significance in RC history is less about having created groundbreaking proprietary technology and more about its role in the early online, low-cost Chinese RC electronics market.

The company was part of a period when increasingly sophisticated brushless motors, ESCs and batteries became affordable to ordinary hobbyists. Its Infinite products helped make electric RC propulsion accessible at prices substantially below many premium Western or European brands.

Its history also provides a useful example of how the RC industry operated through OEM manufacturing and multiple brands selling closely related hardware.
