Hi Greg,
This one came up on the forums the other day. It says it was written for an iphone (mac?), and optimized for the RV-8. I tried it on my PC and it works great. I haven't tried it on my iphone yet. Good luck!
Send me your email address and I will send you a calculator I designed. It is for our RV6A but all you have to do is change the basic numbers and it will work. It is in Excel format. [email protected]
