Default Cesium-lofting?

Hello All,

There are other payloads besides eggs that would be interesting to loft aboard model rockets, like, say, cesium, which has been used as an ion engine propellant: www.youtube.com/watch?v=ytxx95g-kiA (if done over water, it wouldn't even start a fire--on land, at least...).

Enjoyed the video, but it would have been more interesting had I been able to shake the mental image of Borat narrating it.

That was part of what endeared me to that video--it's one of those, "it's so bad that its's good" ones--and the comment about his having more tables (to replace the burned-up one) is priceless... :-)

I prefer TARGETED BOWLING BALL LOFTING to Cesium Lofting.

That's rather expensive even for HPR folks, and even more so for model rocketeers (that would require many A10-3Ts, and even quite a few D12 motors)...

I believe the H699N motor was developed just for this activity.
