I just successfully dropped a parachutist I made run off 2 Hs-55 servos, and a micro reciever... the ram air chute was difficult, but not impossible to make, I made it out of ripstop nylon because it is easier to sew and you arent fighting the static cling wanting to hold the chute closed after you've folded it. chute worked great, we dropped it from about 400 feet from an electric powered glider. total weight of the skydiver with parachute was 3.5oz. it may be able to be lifted by one of the larger helicopters...

There are 4.9 gram proportional servos and under 5 gram 4 channel recievers available now. They'll operate on a single cell 150 mah LiPo. The system can be stuffed into a blow molded plastic figure. PROBABLY you cold keep it under the weight of the 9v transitor battery powered wireles videos systems which the Blade CP/HoneybeeCP2 can get off the ground with. (but they struggle with carrying those..) Steering would be marginal with the round chute.

A small glider wouldn't come out any lighter than the above method of making a parachutist.

It would be fun to drop something out of the heli when it's flying though
interest Thanh,, make sure you got a parachute on the cam.. it will damn fun to see onboard video and also on parachute while you drop down

Hit the ground? If the parachute is any good, impact with the ground shouldnt be too hard.

And anyway, you wont do it over tarmac or anything...lol

Sounds like you're better with a sewing machine than average... but thats still too heavy for the microhelis to lift. It wouldn't be a problem for a 1 meter rotor span (appx 500 mm blades) heli.

Add 3.5 oz to a Blade CP, or a Honeybee CP2 and it won't get off the ground for long if at all.

The camcorder would need a round chute. Any good ram air canopy gets its control from its forward speed as in its glide ratio. The seven cell ram air would be more usefull for the skydiver unless you know how to stall the canopy with equal inputs from both servos- then you could experiment with different fabrics and more cells built into the canopy.



If any one can get your heli to @ 1800' I'll personally take video of it.


also there are some amazing systems for deploying chutes made for sky surfing boards that are small.

But this is the mini heli forum, and a Trex etc can lift weights like that.

Our Micro Skydiver from RCSkydiving.com will work great on a T-Rex. The whole skydiver ready to jump is only 10 oz. Don't let the size fool you, I won the Muncie Skydiver Ralley with a Micro Jumper.

What you need to do is have the R/C Skydiver open the chute and then have your kamikaze heli go rip him up....

But think of the Carnage!... OK we'll let the drop heli get away and send Walkera's at the Skydiver.
