Seagull Extra 300S 61-75 SEA-70B Spares

Keep your Seagull Extra 300S (61-75 size) SEA-70B in top flying shape with genuine replacement parts and quality-compatible hardware. From model-specific items—cowls, canopies, spinners, wheel pants, wing tubes and undercarriage—to wear-and-tear essentials like control horns, clevises, pushrods, hinges, fuel tanks and engine mounts, we’ve got the bits you need. For radio gear, choose trusted options from Hitec and RadioLink, and tidy up repairs with Oracover covering plus durable hardware from Seagull and J Perkins.

Handy fit notes: this category is for the SEA-70B airframe; some “universal” parts still vary by measurement, so check diameters, lengths and hole spacing (e.g., wing tube OD, cowl size, gear mounting centres) against your model or manual. When upgrading servos, ensure torque and speed suit your aerobatic setup, and always use threadlock on metal-to-metal joints. Balance props and spinners, and inspect hinges after heavy arrivals.

Wheelspin Models holds large stocks and offers friendly, expert help if you’re unsure what fits. Order with confidence and enjoy fast UK delivery options, including next working day, so you can get back in the air sooner.
