Beta 2-stage question
Comrades:
Was the Estes Beta two-stager originally for shorty 18mm engines? I have a eBay rescue that I'm trying to figure out.

Has anyone gap-staged 13mm motors? I've heard it's difficult due to small nozzle. I've built a gap-staged Double Mini Max but have not tried to fly it. I suppose I could tape the booster to the launch pad and see if the upper stage lights and flies away!

The A10 has a pretty wide nozzle which is a plus for gap staging, but it's partially cored and that's a negative. I say try it and see!

That sounds somewhat familiar ... whenever my buddies and I flew rockets at the vacant lot, there was always a question of using too much motor ...
"Should I use the C motor?" Everyone else "I would if I were you".
