Got a break in the action with my job so I'm back home with extra time for myself and can pester folks with a few queries. :-)
I'm about to put the finishing construction on a 2 stage minimum diameter rocket. There's a personal project I'm pursuing and multi-staging should give the best results for it. The sims say this thing is going to be a screamer, easily exceeding Mach 1. From cautionings I've seen here, and talking to local club members, the epoxy and plywood fins I normally use will likely fail/shred at those speeds. Any suggestions on beefing things up? Along the same lines I'm curious if a standard nosecone can be expected to also handle the stresses and friction. The one I have for it at the moment is a LOC plastic oglive cone. If friction will heat epoxy above it's operating temp it seems reasonable to expect plastic to soften/weaken as well. Also the thing with the largest motors it could hold it'll pack enough power to slip into the "J" range. Being only Level 1 (for the moment) this is breaking the rules by my interpretation of them. However I recall a posting where someone said that it applies to a single motor, not multiples. If that's actually the case I wouldn't be breaking the rules with 2 motors. Clarification? The only other question deals with the staging electronics, which is activated by the G forces of launch. I may be using it in another rocket that'll be slow accelarating for it's recovery deployment. Obviously if it doesn't arm because there's not enough G's things would get a tad "interesting". So while I wait for the company to get back with me about this specific question I thought I'd ask what's the general rule of thumb for such things, if anyone might know.
