i've flown several tumble recovery rockets, and nearly all have failed to tumble and are featherlight recovery and just fail. the only one that does always tumble is Estes - Tornado (OOP). the top half maple seeds spins down and the bottom half does tumble end over end. sadly its OOP but is easy to clone
 
My Astron Scout clone tumbles consistently and my Golden Scout did too when I flew it for its commemorative launch. My Astron Sprite also tumbled back in when I launched it back in 1968, but I didn't see it until it landed. The only times that I have ever been able to actually see my FlisKits Tumble Weed recover were when I flew it with a special Micromaxx adapter that I built for it. It tumbles during the last 5 or 10 feet before it hits the ground. (It only goes up about 25 to 30 feet.)

Tumble recovery is neat to watch. The rocket comes back in slower than you think it will. In my Sprite's flight, I lost sight of it at liftoff, and had given up searching the sky for it when it literally landed at my feet.

Most of my smaller Art Applewhite saucers, like my Turbo Delta, tumble rather than aerobrake as they recover. These come in the slowest of all.

Tumble recovery, nice and slow.

I am gonna have to get a pie in the sky for sure. Something that odd just begs to be lauched. Also am gonna put the Tornado on my to do clone list. Am I the only one who's rocket build list just keeps getting longer and longer? There is just toooo much neat stuff out to the build and no dam end in sight!
 
Most spool rockets are also tumble recovery.

Many people confuse "feather weight" or "nose blow" recovery with tumble recovery. these are models like the mosquito, Quark, etc. that generally eject the motor casing and sort of float down gently.
As mark mentioned the Estes Scout-1 and II were truely Tumble recovery as are many of the 1st stages of many multistage models. but models like the Tornado, flutter-bye and others are not they are helicopter or mapleseed recovery.

the bottom part of the tornado does tumble, end over end as it recovers,

Sorry Gillard but that's not how the model is designed to recovery. If your lower portion is tumbling instead of helicopter spinning down perhaps you don't have the motor postioned correctly as the model is DESIGNED for both parts to helicopter more like a maple seed spin rather then tumble end over end. Ya might try moving the motor just a bit further back allowing about 1/4-3/8" of the upper stage motor to seat in the lower portion?
Haven't seen the instructions for awhile but I believe it spells out somewhere that both parts "Helicopter recover". I know that on both of the models I fly the Estes 13mm and micro downscale T3 both parts spin.

okay, but i've built two and so far both have had the bottom tumble and i set them up as instructions, you are right about the instructions it does say the they both helicopter recover, i guess that tumble and helicopter are both spins but with the axis changed - either way the tornado is a fun rocket to fly, your T3 downscale must be a great rocket to fly.

Fun Flying....a tiny bit harder to find if you don't have at least two sets of eyes on the lower part LOL!!! but it zips off like all geeeeee Wiz!
 
on the full scale i lost both parts of my tornado when i flew it on a C. had to purchase another one the same day. i did see both parts at apogee, and know roughly where they landed in the wood:rolleyes:
