Wondering what kinds of designs strategies could lead to safe and recoverable C6-5 flights in smaller fields.

- Extra weight in the nose cone? Getting close to max lift weight would seem to limit altitude. What determines maximum lift weight anyway - acceleration to fin effective speed by the time it leaves the launch rod? Would a longer launch rod help?

- Draggy designs? Since drag is related to airspeed, this would seem to still permit reasonable acceleration to fin-effective speed on the launch rod, but limit maximum speed an altitude thereafter.

- Undersized recovery systems are an obvious one... better to have to re-glue a broken fin or two than replace a model that drifts into a tall tree.


Two words, Big Bertha!
