Overview
If you have progressed past the teach-yourself-to-fly stage and are looking to add even more excitement to your RC flight experience, the Super Cub float set is the perfect option. This lightweight, Z-Foam™ float set includes a larger prop (10x8) to maximize the performance of the Cub on floats.
These floats are a Zone 3 product, and are not recommended for beginners due to the difficulty of flying off of water.
Overview
Transform your HobbyZone Super Cub or Carbon Cub RC aircraft into an amphibious flyer with the HBZ Float Set Z-HBZ7390. If you've progressed beyond the teach-yourself-to-fly stage and are seeking to add an exciting new dimension to your RC flying experience, this lightweight float set is the perfect upgrade to unlock water-based flight operations. The float set opens up entirely new flying possibilities, allowing you to operate your RC plane from lakes, rivers, ponds and other water environments across the UK, vastly expanding where and how you can enjoy your hobby.
Designed specifically for intermediate to advanced RC pilots, the HBZ Float Set represents a significant step up from standard wheeled landing gear operations. These floats are engineered to provide stability during water takeoffs and landings, enabling a completely different flying experience that adds tremendous variety to your RC aviation pursuits. Whether you're looking to explore new flying locations or simply want to challenge your piloting skills, this float set delivers the performance and quality you'd expect from HobbyZone, a trusted name in RC aircraft worldwide.
This complete float solution comes ready to install with all necessary components included, meaning you can have your aircraft operating from water with minimal fuss. The thoughtful engineering and pre-assembled construction make this an accessible upgrade for experienced RC pilots ready to expand their flying capabilities beyond traditional grass or asphalt runways.
Key Features
- Pre-built and sealed EPO construction — The floats are manufactured from durable expanded polypropylene (EPO) foam that is pre-assembled and sealed for immediate use, meaning you don't need to spend time building or reinforcing the floats yourself, allowing for a straightforward installation process that gets you in the air quickly.
- Complete hardware package included — Every mounting component you need comes in the box, including pre-bent wire struts that are precisely engineered to fit your aircraft, eliminating the need to source additional parts or spend time bending and fitting components yourself.
- Compatible with original Super Cub and Carbon Cub models — The float set includes a rear float mount specifically designed for HobbyZone Super Cub aircraft, making it an ideal accessory for upgrading your existing RC plane to amphibious operations without requiring aircraft modifications.
- Lightweight design at just 5.5 ounces — Weighing only 150 grams, these floats add minimal weight to your aircraft, preserving the aerodynamic performance and flight characteristics of your Super Cub or Carbon Cub while enabling water operations.
- High-performance 10x8 propeller included — The float set comes paired with a larger 10x8 propeller specifically selected to maximise performance when operating from water, where the additional drag from the floats requires increased thrust to maintain optimal flight characteristics and takeoff performance.
- Substantial float dimensions for stability — Each float measures 23.5 inches (600mm) in length and 3.6 inches (91mm) at the widest point, providing the flotation and stability necessary for reliable water operations whilst maintaining compatibility with your aircraft's dimensions and balance characteristics.
Technical Performance
The HBZ Float Set Z-HBZ7390 is engineered using quality EPO foam that provides excellent buoyancy characteristics whilst remaining lightweight enough not to significantly impact your aircraft's performance envelope. The sealed construction ensures durability and water resistance, critical for amphibious operations where exposure to moisture is constant. The included 10x8 propeller represents a careful balance between increased thrust for water takeoffs and the drag characteristics of float-equipped flight; this larger prop compensates for the hydrodynamic resistance encountered during water operations where conventional ground effect doesn't apply. The complete hardware package, including pre-bent wire struts manufactured to precise specifications, ensures that installation requires no modification or customisation, simply following the included instructions. For pilots operating in the UK and beyond, the floats' sealed EPO construction provides reliable performance across varying weather conditions and water types, from calm inland lakes to rougher coastal waters. The float set is classified as a Zone 3 product by HobbyZone, indicating it's designed for more experienced pilots who have developed sufficient piloting skills to manage the additional complexity of water operations, including crosswind landings, water surface approach techniques, and amphibious takeoff procedures.

Frequently Asked Questions
- Are these floats suitable for beginners? — No, HobbyZone specifically recommends these floats for intermediate to advanced pilots only. The difficulty of flying off water, including water surface approach procedures, crosswind landings, and managing float dynamics, requires established piloting skills. Beginners should develop their foundational flying abilities on conventional wheels before attempting water operations with a float-equipped aircraft.
- Which HobbyZone aircraft are these floats compatible with? — These floats are designed for the original HobbyZone Super Cub and are compatible with various Cub-series aircraft including the Carbon Cub models. The float set includes a rear float mount specifically engineered for Super Cub compatibility. We recommend checking your specific aircraft's manual or contacting our customer service team to confirm compatibility with your particular model before purchase.
- What propeller is included with the float set? — A high-performance 10x8 propeller is included with these floats. This larger propeller than standard configurations has been selected specifically to provide the additional thrust needed to compensate for the increased drag created by water operations and the float equipment, ensuring your aircraft maintains proper performance characteristics from water surfaces.
- How much do the floats weigh and will they affect my aircraft's performance? — The complete float set weighs just 5.5 ounces (150 grams), a minimal weight addition that preserves your aircraft's overall performance envelope. The included 10x8 propeller compensates for the hydrodynamic drag introduced by float operations, maintaining good climb rates and flight characteristics. However, performance will be noticeably different from wheeled operations due to water surface dynamics rather than weight considerations.
- What are the float dimensions? — Each float measures 23.5 inches (approximately 600mm) in length and 3.6 inches (approximately 91mm) at the widest point. These dimensions provide adequate flotation and stability for reliable water operations whilst remaining proportional to the Super Cub airframe.
- Do I need to assemble the floats? — No assembly is required. The floats come pre-built and sealed, ready for installation on your aircraft. This design choice significantly simplifies the setup process and ensures consistent quality. All mounting hardware, including pre-bent wire struts, comes in the package, so installation is straightforward following the multilingual instruction manual.
- What makes these floats different from other RC aircraft float sets? — These floats are engineered specifically for HobbyZone aircraft, with design features including a dedicated rear float mount for Super Cub compatibility and a carefully selected 10x8 propeller that optimises water performance. The sealed EPO construction eliminates the need for foam repairs or maintenance, whilst the pre-bent wire struts ensure precise fitment without modification.
- Can I use these floats on water types other than calm lakes? — Yes, the sealed EPO construction provides durable water resistance suitable for various water environments. However, water conditions will affect handling and safety; calmer waters are more forgiving for developing water flying skills, whilst rougher conditions require advanced piloting ability to manage float dynamics and surface conditions.
