RC Skydiver Help Please!
Hi,
Im building my own skydiver here in Australia and having some troubles. I have sewn a parafoil as per this site,
http://ourworld.compuserve.com/homep...rrecchute3.htm
The thing is, that parafoil is designed to hang off one center point, and not be steerable. Now i know that you turn a parafoil by pulling on the back strings on either side. My Problem is rigging
A) the Slider,
B) Connecting risers to parafoil and connecting risers to skydiver (how far apart etc)
C)The best way to get a servo to pull on turning strings
Im about to build a man like this one (link below), hopefully make him look better and sew a suit. But i dont think i can get arms to move the way he does? Whats the best way to make the arms move? If you guys could show me pictures of your rigs that would be very helpfull.
Link of some one elses skydiver: http://www.olywa.net/yosemiteflash/parequip.htm
Many thanks,
Byron

RE: RC Skydiver Help Please!
If you look at the Jumpers at http://www.Dropzone.com there are many pix on that site and there is also a Forums section that will allow you ask questions. I did and it was suggested that I go to a local DZ and actually measure a canopy and the location of all the risers.
There is also a DropZone Finder that will help you find a DZ any where in the world. You might find some luck there. I can't get ANY answers here just other guys like you and I asking questions of people who have been here before us, But no answers! [:@]

RE: RC Skydiver Help Please!
I realize you guys and many like you have alot of questions. I had the same questions a few years ago. The problem is, these are the problems you must solve to have a good skydiver. Many of us have spent alot of time and money to design what we currently sell. All these dimensions are relative to your canopy and how it flys. There is not a set number that is perfect. Only relative numbers to size, weight, and how you want your chute to fly. We welcome anybody to the hobby of skydiving, but don't think it is as easy as it looks. There is alot of research and development in building a successful skydiver. I try to talk people into buying there first one, nomatter who from and then learning from that to build your own if you prefer. I made many dirtdives early on learning what didn't work. I wish you the best of luck and hope you get into the air.

RE: RC Skydiver Help Please!
That all sounds very well guys. But i cannot justify spending $500+ on a jumper. Our dollar is crap to the US. Plus, with a few months of mastering this, I wish to make affordable skydivers for my fellow Australians.
I have spent alot of time researching this before i started. I spent the last week getting my prototype chute perfect. And beleive me im sick of picking out treads. My chute is at a point now where it glides perfectly hanging from a coke bottle with water.
I just wanted to see how your guys rig the chute to the model skydiver and best methods of pulling with servos. Thus fast tracking my trial and error.
Any pictures or help, other than advise on buying one already made, would be greatly appreciated.

RE: RC Skydiver Help Please!
bodro, Hello!
and hello to everyone looking to make a skydiver. I have info that will help you all. I will post the info in a few days on my web page. The skydiver design is not my design so before I post it I will try to email the person that design the jumper to ask if i can post it on my web page. I got the design free off his web page, but it no longer is up and running.
so ck my web page in the next few day. I will post here if it is a go to post it on my web page. The design will take you from A-Z, Yes even a chute that he came up with. I will post a Chute design to. give me a few days to email some people, and if everything goes good it will be a great help in making your own skydiver.
Thx, Wil

RE: RC Skydiver Help Please!
Nice websites Byron!
Years ago, I ordered some plans for a skydiver and canopy.
While the skydiver looked easy enough to build, the canopy was a bit beyond my sewing skills
I've seen a couple of websites for custom chutes, but they are rather expensive.
I was wondering if anyone has tried using the ram-air type para stunt kites. Most of them span out at just under two meters, and come in many styles and colors. I'm sure they could be modified for RC use. I've seen them on ebay for much less than it would cost buy one specifically for RC.

RE: RC Skydiver Help Please!
Hi all:
I´m from Mexico, so here you can´t get a comercial skydiver so i decided to build mine.
I´m scratch building my own skydiver but have some problems with measures. My dude is 18" tall, so he has plenty of room to install radio gear.
My problems start when i have to figure out how big the parafoil should be, i have read most of the comercial skydivers has 60" by 24" more or less, but its dude is 14" tall.
Question is what are the most adequate measures for my parachute?
what is the correct weight for my dude?.
I will appreciate any help.

RE: RC Skydiver Help Please!
you are going to get alot of different answers on this one. alot of combinations fly good you just have to find a spot. ours are 49" wide and the jumper are 3 lbs. or so. this works great for us. we also have a 32" chute that has a 10oz. skydiver on it and works great. our biggest is 4-1/2 lbs and has a 63" chute. That is the problem of building your own , there is alot of trial and error. the length of the lines with very with people also. No one combination is perfect so to speech, there are several that fly good with different combinations.

oops. Edge Pilot, I just sent an email asking about the dimensions of the small canopies you sell, and you answered that right here.. >< *needs to search the forum before bothering folks with questions that may or may not have already been answered here*

RE: RC Skydiver Help Please!
I just found this board. Neat!
In reply to the question of using a ram air kite for your chute- The link suggests it will not work.
A couple of years ago I played around with a self built RC skydiver. I figured it would be something fun for me and my son to do.
I saw the adds for the kites and figured why not? To make a long story short. I built the man and rigged him to the kite. I did do some drop tests with a chunk of wood first to see how the kite flew. I don't remember which brand kite I used but it opened just fine. I did use a small drogue chute attached to the to center of the main chute. The only fouling problems I had were when we would let the skydiver free-fall for a long while and reach terminal velocity. Then when the chute was deployed the jerk would sometimes flip the man up into the strings and foul the chute. The drogue chute mostly elimintated this problem. The thing I never totally solved was the best angle (speed) and steering set up for my rig. Mine typically flew a little slow and didn't have the authority to manuever in windy conditions. I know by changing the foil angle I should be able to fix that.
Anyway, it was a fun project for the summer. I guess I need to get it out again.
