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! 4" Cyclotron Rocksim Cyclotron Instructions DESCRIPTION Complexity: IntermediateDiameter: 4.0" reduced to 3.0"Height: 67"Weight: 3lbs 7ozMotor Mount: 54MMParachute Size: 42" ripstop nylonShock Cord Type: NW-15 15' 3/8″ Nylon with sewn loopsShock Cord Mount: Eye Bolt SCM3Fin Thickness: 6 X 4" Tube FinsRing Thickness: 1/4"Launch Pad: 1010 Series Rail GuidesInstructions: Cyclotron instructionsVinyl Decal: Yes
