4" Cyclotron

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 newly designed 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, 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!
