I recently pulled my old rocket gear out of the basement closet where it had been for 20 years. In there were unopened packs of Estes A and D engines, as well as two single use Aerotechs - E30T and F25W. Assuming I can even get the ATs to ignite (which might be a big assumption, given what I've read about old white lightning motors), I don't want to put them in any rocket that relies on the ejection charge actually working, so I was thinking of picking up a fun kit that doesn't need it. In general, I will probably be flying 24mm a lot more than 29mm though. Does the Turbo Vortico do alright on 24mm D/E engines with an adapter, or am I better off just tossing the F25 in the trash and getting the 24mm Mega Vortico instead? It looks like the Turbo is actually a fair bit lighter than the Mega but quite a bit larger in diameter, so I'm not sure how to predict its performance.
