is balsa wood gliders better than styrofoam gliders?

Gliding ism't dangerous and neither is falling but crashing into the ground at high speeds can hurt alot.

My suggestion is don't be cheap and buy a real one.\nYou don't understand the positive and negative forces\non the frame and wing spar. It's not like building a kite\nand take it out for it's first flight. But If you think that you can\nbuild one and fly it with no experience with building or even\nflying one go right a head, I love it when I see some knuckle\nhead make the news, I just laugh my azz off.

minimal. \npower to weight ratio is significantly more important, as is wing design (the "lift" it can generate).\nplacement only concerns the weight distribution.

Gliders, being unpowered, do not stay in the air indefinitely...they are continuously falling.\nSomehow (through various means) a glider is raised up into the air and released.  At the very top, the glider has some amount of gravitational potential energy which is gradually expends to gain kinetic energy (so it can fly).  In order to keep moving, the glider must slowly fall.\nHow fast the glider falls depends on its mass and dimensions.  A large factor in determining how long the glider can stay in the air is its wingspan.  A larger wingspan allows the glider to "glide" better and keep itself up longer for a given mass....but make no mistake about it, it is still going to come down eventually.

Internal skeletons are much better for a larger organism because it gives the body internal strength and integrity and protects all the vital organs incase the flesh can be penetrated. It also gives the body more strength in keeping its own weight up against the forces of gravity. However, for a very small, light organism I believe an exoskeleton is superior since gravity does not pull down on the organism as much.

they both are good but i think if you got a back pad for a fiber glass it would be beter than a wood board.

what size are we talking here? small use some of that packing material and use a exacto (sp) knife to form, shape sides roof , put it together with something that won't melt the Styrofoam

Its tricky to start out, and it sounds scary, but you don't actually need that much water under your board to skim it; you are probably just a little early when you throw your board down.  Wait until the water is lower than you think you need to make it, that is probably the right time.  And in general, if you are skimming on a foamy or carbon fiber model, you need even less water.  We would rip it on practically damp sand.  Woodys are a little more forgiving and can float on a little more water but not much more.  Also if you look at pros when they ride, they are lining up their ride down the beach, not right in front of them;  I used to make this mistake all the time.  Try to train yourself to throw the board down and once your on it look ahead and not down, or you will wreck, and it will hurt...

engineered wood is stronger.

both boards are better!

I've broken several graphite shafts.  Steel shafts are better if you are younger, or stronger with a faster swing speed.  Steel provides a heavier club, and better feel for what the clubhead is doing, and what happens at contact.  Graphite tends to dampen vibrations from contact, break if abused, and be too light for me to have a consistent swing.

Sounds a bit dangerous!  But I;m sure if you google sometime like "hang gliding kits" then you should get somethin?!\n\nGood luck...and be careful!

Hey, I'm not sure what kind of skateboarding you are looking to do,(cruising, tricks) but I would go with a board that has carbon fiber layering technology, like you said, Lib Tech, and Revolution. Also, Element skateboards has recently started a line of carbon fiber skateboards. I think alot of companies have have jumped on this trend, so you may want to look into it. Whatever you find, have fun and good luck!

it depends on which grain you like the best. if you work with composite, then go with composite. If you also work with a wood bat in a game its best to stay with the same type of wood for the cages. My personal favorite is maple, and i can hit better with it. good luck

Carbon fibers are stronger, stiffer and lighter than glass, aluminum or steel and exhibits less thermal growth.  See the link.  Carbon nanotubes will perform even better if they can ever be cheaply mass produced.

the grobat is pretty good- have tried both and like that better. I play baseball on the boys baseball team. (just in case you are wondering why i am answering this and am a girl)
