My A-10 is already certified "Experimental Class". Billy Edwards is a certified Inspector and signed me off during our "HawgFest" weekend last August.

Now if I have this right: A fully fueled 55lb F-15 is:

1. Not experimental
2. Limited to 45lbs thrust as a single
3. Limited to 50lbs thrust as a twin

A fully fueled 56-75lb F-15 is:

1. Must be certified "Experimental"
2. Limited to 1:1 thrust to weight, single or twin powered no matter
