Operation and construction of air flap, and ejector. Adjustable to deploy at apogee every time. Dirt cheap to make. No timers, radios, or batteries. Works reliably at whatever pressure you adjust it to but ONLY at that pressure. Click "Show More" & read important notice.
NOTICE ! Once it is adjusted for a PARTICULAR pressure it is reliable and performs consistently AT THAT PRESSURE and ONLY at that pressure. At a higher pressure the velocity is greater and the flap might stay down and never deploy the chute. At a lower pressure it may deploy early while the rocket is still climbing. So pick the pressure that you like, adjust it , and STICK WITH THAT ONE PRESSURE.
Store the rocket in an air conditioned room away from direct sunlight to avoid degrading the rubber bands. As they loose elasticity your adjustment will become wrong and it will deploy late or not at all.
