Does anyone know if the tentative 2010 rules from the Summer Institute included any limit on the chord of the main wing?

I understand it is very likely that the 2010 WS rules will maintain the 1.5 g maximum rubber motor weight and 7.0 gram minimum airplane weight (not counting the rubber motor).

Thanks.

So, is it known for sure that Wright Stuff will be an event in 09-10?
Is it possible that it will not be a monoplane, like this year??
Anyone know where i could find the event rotation schedule that was removed from the official SOINC site?
Thanks!

first to get the event rotation, just go to soinc.org
second it will definetily be an event next year
third, it will most likely be a monoplane, but you do have to wait until the rules come out

That's not the event rotation. They stopped publishing that this year. I still have an old copy but it's not incredibly helpful as they never seemed to follow it anyway.

getting back on topic, what website would anyone suggest to buy carbon edged blades at?

In addition, this site has carbon steel single edge blades, don't know if they are as sharp as the old carbon double edged ones:
http://www.americancuttingedge.com/Stoc ... eedge.html

Or this site has all kinds of carbon steel blades, including the old double edge kind that are half as thick as the above single edge:
http://www.emsdiasum.com/microscopy/pro ... lades.aspx

And if you want 1,000,000 of them:
http://www.diytrade.com/china/4/product ... blade.html

Or check e-bay, that's where I got mine from.

half as thick= better right?

thanks for the links. the one from a2z corp seem to be the best value but it's not a big difference.

Thinner? Depends, sort of/sometimes.

Sharper is most important for clean cuts. Some folks swear by carbon steel for max level of sharpness capability, not that it matters if not sharpened properly. Real razor blades for shaving need to have, and the market ensures they do have, a VERY sharp edge for comfort. Customers just won't shave with a dull, painful blade. Single edged razors are more commonly used for craft purposes where sharpness isn't so critical, so less market reinforcement of sharpness.

For real light balsa, thinner becomes important to avoid damage to the wood edges BEHIND the cutting edge. But its harder to control because it can be floppy.

For med to high density balsa, you need a heavier blade to have control of the cut.

Note, the real advantage to carbon steel vice stainless double edge shaving razors is the ability to break and reshape the blade to more usable shapes. Carbon steel breaks with clean edges, stainless steel always bends and leaves a burr that snags in the cut.

Further note, there is a pretty good competitor to double edge razor blades for sharpness, real scalpel blades, not craft blades. Sharpness demanded by prime customer, surgeons, benefits us hobbiests. And they come in a nice variety of shapes and have nice handles, improving safety over double edge razors. Some of the previous links also sale real scalpel blades and handles. I just use my generic X-acto handle to hold them.

Great for stunts, but not practical for S.O. Electric powered planes going in circles would stay up until the batteries die...longer than an event block or a tournament, for sure.

Unless you wanted to make it an event in which competitors are judged on their maneuvers, but that makes it an event that judges the capability to control an RC plane, not an event that judges the capability to build and trim a plane. Plus there's too many factors then and it becomes way too subjective.
