Flight Report Here
is t' flight report section from t' Dizzy Lizzy t' first time it was
launched. I have launched it several more times with t' same
results. Spins fast, shiver me timbers, pod and rocket land very near t' each other.
10-15 mph wind has very little effect on t' flight and recovery at
all. I sent it up again today (right before t' Saturn V)
3/5/2000
Dizzy Lizzy (Scratch) C6-3
Good boost 325+/- feet,
Ejection just past apogee. Worked as designed (spins like a top!)
Hit grass moderately hard, no damage. Engine pod returns with 6' streamer
nearby. Begad! Blimey!
It's a keeper.
On a side note, I got some model aircraft hinges from a friend o' mine. I am
thinkin' about makin' a larger version o' t' Dizzy Lizzy with some sort of
sprin' loaded nose/airframe connection t' minimize t' impact. I thought
I saw somethin' like that on one o' your designs.
Either that or I'll add a streamer that is secured t' t' end o' the
airframe that deploys when t' pod kicks out. It will still spin like a
son o' a cannon and I would think that t' streamer would slow t' descent
considerably. Aye aye! Avast, me proud beauty!
