Depending upon the scale you build in it seems a long distance to gap. Moreover, if you keep to scale there a point of physically open space at the interstage...
The tiny staging timers from Perfectflite and Pico are another way to go. They're non-mechanical and safer than the Adept's "mass on a lever" or a mercury...
... It's an unsealed mechanical "limit switch" with a piece of brass as a weight. It's more likely to wear, get stuck, etc. With that said, many people use...
The Perfectflite timer actually comes in two versions: one with a G-switch and the other without. The version with the G-switch won't arm its event unless it...

Huh? You mean if the orginal had a 10:1 thrust ratio, and you make your model with a 10:1 thrust ratio, can you expect your model to be stable? Beats me, but...
Jeff, I took your post TWO ways: (1) - As long as the CG remains ahead of the CP, the rocket will be stable. The Thrust / Weight Ratio determines acceleration,...
