Crashability!!!!!

[quadrirotor]

Don't forget crashability when you built a gyro!
(don't forget to read the warning!) :eek:

andre, i think I am very crashable :D

Dont forget to take out your fingers from your nose on landings !! :D :D :D

I didn't mean trashable!

Zeeoo, you are too troll!

[Victor Duarte]

you miss some sense of humour, andre

I see that you want to contribute actively to this thread!...What do think it could be done to make the gyro safer in case of a crash? i know that you have good ideas (a little pomad doesn't hurt!...). :D

[Victor Duarte]

well, just mad ideas :

- a spheric airbag (tested yet for free falls and aplinists)
- a chute hanging the nose, the tail crumpling smooths schock
- real shock proof tanks
- prop and rotor stoppers (strong rods pushed through)
- smaller and lighter rotors
- ducted props
- sandwich or honeycomb airframes
- high dampened langing gears ( for vertical crashes)
- upper rudder part "breakable" to allow a "first alert" without loosing yaw
- a spring poisitionned rotor
- a gyroscopic stab
- an emergency rocket prerotator to regain rpm
- an engine dropper (lighter, less inertia)
- a good gyro
- a good pilot
- a good engine
- a good F***
- live in alaska
- be dead yet
- be poor
- not to fly
- say the aerial controller he is a D...head
- a book from ron hub-bar
- not a RAF
- the joke of the day
- salp and pepper
- mix
- heat
- ketchup
- eat
- mmmm goood

Not bad Victor, you are not as mad as you think... I recall what is very important:
- real shock proof tanks;
- sandwich or honeycomb airframes;
- high dampened langing gears ( for vertical crashes)...

All that can be inspired by some mature mechanical sports (car races F1, hydrofoil races...).
For F1 races, the cockpit can sustain a 200 kmh crash! it is made of composite-carbon-honeycomb like material...

Not bad Victor, you are not as mad as you think
thanks andre, thanks to allow me to not underestimate my self :D :D

there's a thread about high carter struts here, check it.

carbon honeycomb > light > expensive > not easy to repair > breaks in chucks

i think epoxy/foam/epoxy can be a good compromise.
why do you think i designed my airframe with that ;)

thanks
