I wanted to add to Steve's old thread...I built my Sonic 160 almost exactly the same and finally had a chance to fly it last weekend.
F15-0 to F15-8 direct staged off a 6' rail with an el cheapo peak altitude altimeter and a beeper. 3" by 3' streamer for recovery. It flew great, way high, and was not visible at ejection (via motor delay) due to overcast conditions. I heard the pop clearly, and then picked up the beeper. Interesting it had weathercocked into the wind quite a bit, and as it drifted down I could hear the directionality of the sound from the beeper changing from downrange to directly overhead, and then finally past me in the opposite direction . That's when I got a visual on it, maybe 200 yards from the truck at touchdown. The beeper really saved the day. 3350'. I think if it had gone perfectly straight it might have gone 4K. I have pondered a G80-4T in the booster staged to an old single use AT G25 (no thrust ring) using old school upper stage ignition techniques. |

Flew this thing again yesterday with F15's in both stages. Jeez did it go bye-bye. I didn't put a beeper in it this time and thought would be lost for sure as it headed significantly downrange.
Got lucky and found it - 3680'!!! |

If you do a 2 stage G, put the lower thrust on the booster and have 2 seconds staging delay.

You know what I might do....I have an F41-0 AT that would be dandy staged to that G25....
