$73.03 $112.35 In stock

4" Cyclotron tube fin rocket! Tube fins make this a super a straight up! Tube fin rockets are rarely affected by wind and don't receive the weathercock like typical rockets with normal fins. Recovery is a 42″ ripstop nylon parachute with central spill hole making decent as straight as your ascent. Packed with features including rail guides, motor retention, vinyl decals and more! Standing 67″ tall, a 54mm mount makes this a great flyer and great candidate for certification flights. A bit of a different, but easy build from the norm. If you like fillets......here you go!

Customer Reviews (4.2 / 5 · 5 reviews)

Violet ★★★★★

Windy days used to mean my launches went wherever they wanted, but this one flies straight up almost every time. The tube fins are a clever design and recovery has been smooth on every flight so far.

Ryan ★★★★★

The tube fins really do keep it arrow-straight, even with a crosswind that would've sent my old fin rocket tumbling. Recovery was clean every flight, nothing scorched or cracked after four launches.

Lily ★★★★☆

Flew it twice on a windy day and it barely drifted, which is more than I can say for my other rockets. Only knocked off a star because the tube fins make it a bit of a pain to pack in my range box.
