All right. We've been working on a Hawk Talon 3 for a while now. Its got the fiberglass version of the PML CPR 3k. It can fit one Co-pilot altimeter.. Not being one to like having just one altimeter, my dad had me figure out a way to put a backup in. After all, its an expensive rocket, and lots of pricey stuff aboard, and we dont want to lose it due to an altimeter failure!
So, I figured that the only place to put it in was in the nosecone (has a payload bay in it) . This eliminates a barrometric altimeter, and the only accelerometer ones I found are VERY expensive.. I found the Perfectflite minitimer. I think this will work well, but i have yet another problem! I would have to run the ematch wire all the way to the drogue compartment, through the CPR, which I can't... To have the timer fire into the main bay, the time delay wouldnt work. if i set it to fire at apogee, the main deplys at apogee... bad.. if I time it so it fires at a lower altitude, in the event of the main electronics failing, this would deploy the main a few feet below the ground...
All help would be very much appreciated..Thanks..
