My first full Java app. Version 1

[murankar]

Today I completed my first working app that is almost wothy of deploying. I still need to add some stuff for error handling and do some minor testing. Its really just a basic calculator for disk loading and disk soldidity. I got the Idea from RCHN since they gave me the formulas I just automated the math. I would like to add other calculators to this that would make it a great tool.

Now this is a zipped jar package wich may rquire you to run the package from the cli. I know i Linux its: java -jar <packagename>. I think you might be able to right click the jar file and run from java environment.

All I had to do on windows is double click the file and it ran. Now to test it.

I'll download it and have a look later uri. Sounds like a useful tool for planning builds or changing equipment on an existing machine.

To me its just numbers but if you really want to know how your setup might fly the numbers help. All I know on this subject is that the lower the disk loading the more floaty the heli feels and the higher the number the more aggressive it feels. You may also have a trade off on flight times as well. I want to incorporate other useful calculators into this later on.

sounds good. downloading now. it would be good to see how much of a difference it will make if you where to go on a weight saving binge like KevG recently did with his 250.

Oh I for got to mention a few things:

One) Head radius is measured from center of the whole for the blade bolts to the other.
Two) blade length is supposed to be from the bolt whole to tip.
Three) Cord, you guys should know what the blade cord is, if not its the width of the blade.

The article explaining this topic is on RC heli Nation under tech tips and its currently on page two of the tech tips. Look for the article with the PI sign for an avitar.

One more thing, you can get away with not using head radius, just that you wont have a true representation of your numbers. If you decide to do this then enter 0.0 in that field. I will add tip pop ups to the revision and will post that up.
