> I'm in the process of building a PML Stratus and I'm getting to the
> point where I need to decide if I deviate from stock or build it stock.
> Here's the dilemma:
> The Stratus is an altimeter deployment only near 38mm minimum diameter
> high performance bird designed to go 12,000' on an I.  The problem is
> that it is designed for single deployment at apogee.  Now, I'm not as
> young as I once was and I have no desire to chase a 22 oz. rocket as it
> drifts in under main chute from 12,000'. <g>  So, I've gotten a good
> suggestion from Darrell to cut a small section of BT and use a floating
> coupler that is blown out by the motor ejection charge, staying with the
> payload section and then blows out, releasing the main chute by the
> altimeter controlled charge.  Does anyone see any unforeseen  problems
> with this scenario?  It seems too easy to be true, but I think that
> it'll work.
> A couple of questions remain before I start:
> 1. Will the rocket be structually sound enough under high G's with a
> "floating" coupler?
> 2. The kit uses a piston for ejection which I'm assuming won't be needed
> or wanted considering the modification. Correct?
> 3. Would the addition of a small, dummy payload section be a preferrable
> option to the above?

> Your comments are welcome.
