Me -163 Komet - Rocket Plane - 6S Madness

[L Edge]

How are you able to predict the height without knowing the aircraft weight? I bought regular D rockets from Hobby Lobby and removed the ejection charge. I'm igniting it with a servo connected to a 3S battery. It's super basic but it should work fine.

I assumed you will get it into the air where thrust of motor is equal to weight of plane and firing off the rocket has a max weight of 14 oz (drag of airplane) will give it a max of 400 ft according to the charts.

By the way, I used only 1 cell of lipo (used the balance connector) and the gear servo to arm rocket.
Have a video of my Bell-X1 being launched statically.
