I haven't done it myself (I've flown my totally stock Magnum on J415s
and a K185) but I've seen it lots of times and 10 seconds is probably
about right. Use tons of shock cord (I'd use about 30 feet of bungee)
and even if the ejection is slightly early there shouldn't be any
damage.

Don't lose it, back it up.

Back it up, don't replace it.

Jeff Stai of R.O.C. has flown a Magnum many times and knows of others that have as well
(ROC-Stock had a 4 way magnum drag race). He should know, ot know someone who does.


Pay Forward,
Jeff

aw shucks...;-) Yes, the Magnum flew very well on a J415, a K185, and a K550 was the last and best
flight of all. The 10 sec delay was just right.

It will fly well again on a K550, as soon as I complete repairs...;-) jeff

I have flown my Magnum on several different motor combinations, all from
launch sites within 300 ft of sea level. Ready to fly weight, less motor
is 10 lb.
Flight motors       Altitude
K185, 2G200         4994
J800                3679
K250                7132  lots of downrange on this one.
J460, 4F62          2953
J800                3731
I250 (homemade)     1637
K550                4970
J350                2043
I500, 3H70, 3G40    4095  lots of downrange on this one.
All deployments were by altimeter. I use the Adept RAS2 recording. I can
look at the data to determine when ejection occured if desired.
An interesting observation was that on the K250 flight, maximum velocity
was about 6 sec. into the burn.
