Designed to allow flights of Jolly Logic altimeters in 24mm diameter airframes like the Rocketry Works Socrates or Toobish kits, this 3D printed ABS nose cone fits in an 24mm (BT-50) body tube and attaches to the shock cord just like a typical nose cone...

You can replace the LCD screen in any Jolly Logic altimeter manufactured after 2013 with this LCD screen. You can review Jolly Logic's Visual Repair Guide to see what's involved in the replacement.

This Velcro® strap with a bright red ARM ELECTRONICS banner helps you remember to arm your electronics before flight.
