Air Density & Altitude: AirLab

The app was great… initially. Unfortunately, you pay for the app and now it won’t retrieve data anymore. Of course, I can’t get a refund for the purchase. But would much rather the app function.

I use this tool for flying control line model planes and making sure we have the right mixture of nitro in our fuel. Having enough power to perform well determines if you will place in competition. I use it a lot.

Very useful for making jetting chart for carburetor engines.
