Osprey IV
Description
The Osprey IV is a fully tested, operational, 3D printable, model rocket. It works like a charm in the wind and on clear days using B or C rocket engines of standard diameter. I use Estes, but you can probably get away with anything! You will need a launchpad (I got mine off Amazon) an electric launcher, fuses caps and a parachute. Also, an elastic cord. launch safely away from buildings and trees. Also, DO NOT TRY TO PRINT THE "The Osprey" FILE! It's just a thumbnail!
