ZYHOBBY 360ML Fuel Tank — Lightweight and Simple
The RC Gas Fuel Tank 360ML from ZYHOBBY is designed to fit compact to mid-size RC airplanes. It ships with a 360 ml capacity, and the fuel inlet, outlet, and cap use metal material, which helps resist wear during frequent fuel changes. Weighing approximately 66.5 g, this tank offers a balance between lightness and durability for small to medium electric or gas-powered airframes. It complements engine setups that require reliable fuel presentation without adding excessive weight to the airframe.
A practical choice for trainers or sport models, this tank emphasizes straightforward installation and dependable seals. If you’re upgrading an older model or building a compact gas-powered plane, this unit provides a simple, robust option that minimizes cross-threading or cap leaks. Review the fit with your fuselage dimensions and mounting hardware to ensure a clean, vibration-resistant setup during flights.
ZYHOBBY 700ML Fuel Tank — Mid-Range Capacity
The 700 ml model from ZYHOBBY provides a larger reservoir suitable for longer flights or bigger RC planes. With a metal inlet/outlet/cap, the design emphasizes durability under engine vibrations and fuel pressure. The added capacity supports extended flight times without frequent refuels, which is beneficial for pattern runs or scenic flights. The tank’s transparent plastic helps monitor fuel levels at a glance, a practical feature during long sessions.
When integrating this tank, verify the mounting points and hose connections to prevent leaks during aerobatic maneuvers. The improved volume also means a slightly increased weight and balance adjustment may be needed on some aircraft. This option is well-suited for pilots who want more endurance without stepping up to the largest tanks in the line.
ZYHOBBY 500ML Engine Fuel Tank — Balanced Size
ZYHOBBY’s 500 ml tank sits between compact and large capacities, offering a balanced option for many sport and trainer aircraft. The unit uses a metal fuel inlet/Outlet/Cap and weighs about 92.5 g, which makes it sturdy enough for frequent flights without adding excessive weight. The tank’s construction focuses on reliable sealing and general resilience, aimed at reducing fuel leakage risks during high-vibration events like sharp turns or landings.
Users benefit from a straightforward setup with standardized hardware. If you’re replacing an older tank or configuring a mid-sized model for the first time, this 500 ml option provides a practical compromise between range and weight. Check your airframe’s fuel line diameter and the window clearance to ensure a snug fit within the fuselage.
ZYHOBBY 1000ML Tank — High-End Endurance
The 1000 ml fuel tank from ZYHOBBY caters to larger gas-powered RC planes or pilots seeking extended flight times between refueling. It ships with a metal inlet/outlet/cap for added durability, and weighs about 114 g (0.25 lb). The higher capacity helps reduce the frequency of fuel stops, which is especially advantageous for hobbyists conducting multi-flight sessions or longer practice runs.
Installation considerations include managing the weight distribution and ensuring a secure mounting area capable of withstanding the fill pressure. The transparent body allows for quick visual checks of fuel presence. This tank is ideal for medium to larger airframes where fuel endurance is prioritized over payload weight savings.
HobbyPark 600CC Tank — Durable and Ready
HobbyPark offers a 600 cc fuel tank that is ready for RC gasoline aircraft. The tank is designed with compatibility in mind, including a sturdy body made from quality plastic and aluminum components for the inlet/outlet and cap. The kit typically arrives pre-setup, enabling quicker installation and reducing additional accessory needs. This unit supports robust performance in models that require reliable fuel supply under varying flight conditions.
As with other tanks, verify the hose connections, mounting hardware, and airframe compatibility before flight. The 600 cc capacity makes it a strong choice for standard to mid-sized models, balancing endurance with a moderate weight footprint. Its construction emphasizes longevity under vibration and exposure to fuel solvents used in common RC gasoline blends.
Buying Guide — Key Purchase Considerations
When selecting an RC airplane fuel tank, consider the following factors to ensure optimal performance and safety:
- Capacity and flight duration: Choose a tank that aligns with your typical flight length and the engine’s fuel consumption. Larger models reduce refueling needs but add weight and may affect balance.
- Material and seals: Tanks often use plastic bodies with metal inlet/outlet caps. Look for tanks with robust seals and corrosion-resistant fittings to minimize leaks and wear.
- Fitment and mounting: Check dimensions and mounting brackets to ensure compatibility with your airframe’s fuselage, firewall, and servo or pump placements.
- Weight and balance: Heavier tanks affect center of gravity. Plan for forward or rearward adjustments to maintain stable flight characteristics.
- Leak prevention: Tanks with secure caps and well-sealed connections reduce fuel leakage during acceleration, inverted flight, or rough landings.
- Compatibility: Verify compatibility with your engine type (gasoline, methanol, or other RC fuels) and hose diameters to ensure a clean fuel pathway.
- Ease of installation: Some tanks come pre-assembled with hoses and mounting hardware; others require additional parts. Factor in the time and cost to complete installation.
- Durability under vibration: RC models experience significant vibration. Look for tanks designed to resist cracking and deformation under flight stresses.
From a safety perspective, always store fuel away from heat sources and ensure fuel lines are tightly secured to prevent leaks. Regularly inspect tanks for signs of wear, cracks, or degraded seals, and replace components as needed to maintain reliable operation over multiple flights.
