I launched this rocket twice so far, The first time everything worked perfectly although the parachute opened very near to the ground (15m) but on the second launch the parachute cord detached from the nose cone and the rocket fell without any means of slowing down. Thankfully it landed in tall grass and the rocket remained in great condition. For this launch I used D12-5 Estes engines although next time I will try to get some with a quicker ejection delay. Thanks for watching
