RC rocket missile with drop mechanism

thingiverse

This is a RC Rocket with Helicopter recovery system (no parachute needed) and drop mechanism that can be attached to any drone or airplane. I did it a little bit shorter than the original version , this way can fit on my "Skywalker" 1900. I used small 4.5gr. servo HD-1440A and 2 steel bars ф1.5мм diameter and 35mm and 29mm long with soldered nut and bolt to each. Make small circle on the 35mm bar with the same diameter as "stopper parts and attach it to the servo" solder a m3 bolt to the other end as shown on the picture , solder the nut to the end of the other bar. Feel free to change the trigger system or experiment, This work very well for me and drop the rocket without fails. To stay well fixed to the base the bar that pass trough the lock part of the rocket must be tight or the rocket will wobble. You can experiment with the hole of the lock a little bitt upper or down.The 3 fins in the middle must be loose ,so can open easy when the rocket is falling. Some parts are tight and need sanding. The inner circle of the part called "lock" that hold the rocket must be tight, so sand it just enough to enter!!!
