Choosing between two rc boats & aircraft can be less about the airframe name and more about what you want to do next: build a vintage hobby project or charge an included electric model and fly. The JEMCO Fun Scale Series COBRA and MinimumRC ASK21 serve those very different moments. The clearest split is simple: the COBRA is an unassembled hobby-grade kit, while the ASK21 is ready to go in an electric glider format.
Quick verdict
Choose the JEMCO Fun Scale Series COBRA if the rare early-edition character, wood construction, and assembly project are central to the purchase. Choose the MinimumRC ASK21 if you want an included ready-to-go package with electric power, assisted stabilization, and manual flight mode. The listed-price gap is $800.01, so this is also a decision between a substantial build project and a lower-priced route into RC flying.

Product notes
JEMCO Fun Scale Series COBRA
The JEMCO Fun Scale Series COBRA is the more distinctive choice for someone who wants the model-building process to be part of the hobby. Its all-balsa description, hobby-grade classification, four-channel R/C format, and nitro-and-glow-fuel setup give it a traditional scale-kit identity. The rare early-edition wording and vintage designation also make it more relevant to collectors than to shoppers seeking a quick setup. The main limitation is concrete: it is an unassembled kit, so the purchase centers on construction rather than an immediately flyable format. It also carries the higher listed price in this comparison. Choose the COBRA when the vintage kit character and hands-on project matter more than included ready-to-fly convenience.
MinimumRC ASK21 RC Glider
The MinimumRC ASK21 is the practical pick for a buyer who wants a defined electric flying setup. It combines a 60g airframe with an 820mm wingspan, a 1020 brushed motor, integrated brushed ESC and receiver, four linear servos, and a folding propeller. Its three flight modes give the listed package a clear progression from active leveling-assisted stabilization to manual control, and the description specifically presents it as suitable for beginners through experienced pilots. The limitation is that its foam construction and electric format do not provide the wood, nitro-and-glow-fuel, vintage-kit experience of the COBRA. Choose the ASK21 when included components and selectable flight modes are more important than assembly.
Final choice by use case
- For a vintage kit or collector-minded project: Choose the JEMCO Fun Scale Series COBRA, whose rare early-edition wording and vintage designation set the direction.
- For the lower listed-price choice: Choose the MinimumRC ASK21, which combines the lower figure in the comparison with an all-included RTF format.
- For hands-on assembly: The COBRA is the clear match because it is explicitly an unassembled kit.
- For electric RC gliding: The ASK21 fits the brief with its electric fuel type, folding propeller, and selectable flight modes.
