After flying 3",4" and 5" rockets for some time now, always with two altimeters,I think it is time to knock the dust off my Little Dog rocket and start flying it again.
I have always been afraid of fly this one very high, even radio tracking, for fear of loosing it.
I now have a nose cone set up to take a couple new GPS units I have.
Figure it will be be a good test bed rocket to get warm and fuzzy with the GPS units.
My problem is I am a firm believer in redundancy and my AV bay as of now is set up for only for a single alt. a PerfectFlite MAWD which I do trust.
On flight up to now I have used motor ejection as back up on this Little Dog.
On 4g motors and up that will not be an option. Factory delays are going to be to short.
In the past I have had two occasions where an ejection charge did not fire.
Redundancy saved the day.
In both cases I think it was due to a bad e-match.
I do not use e-matches from that supplier any more.
So what I am looking for is what techniques do fliers flying dd with a single altimenter do to minimize a single failure?
Two e-matches to a single ejection charge ect. and how comfortable do you fell doing so.
My thoughts right now are one altimeter + a bad e-match = a bad flying.
And for anyone who suggests buying two Ravens I have thought about that.
Checking Adrian's web site the soon to come Wren sounds promising.
