I wouldn't use feedback. Class-E amplifiers have a very narrowband of operational range once you have it tuned. I'd use a fixed oscillator, and build / tune your resonator to match that frequency. Then tune the whole Class-E system to match driver / resonator.

If your a noob i wouldn't recommend a class-e design - they are pretty complicated to be working correctly and require a fundamental knowledge of class-e operation.
Steve has other designs on his site which are great for noob designs including his mini DRSSTCs etc...

i have built it and my antenna was around 7" long and the wire wrapped around the base i used 8 turns and it works fine
i see you live in Bradenton. I lived there for about a year at the Harbor Pointe, before of course it became Harbour Hood. Sounds like that whole place down there is going downhill.
