What are you currently flying? If you have never flown a gasser then trying to learn the ins and outs of giant scale and IMAC at the same time may be a bit much for some. There is no wrong way to go about this but odds are that if you go 35% the airframe won't be around long enough for you to utalize it in the upper classes. Sorry to sound so negitive but after 9 years of flying IMAC I see lots of nice airplanes getting trashed as their pilots come up the learning curve. If I were to start over now, I would go with a 50cc airplane. There are several good airplanes available that would be very competitive in basic. Select equipment that does well on the resale market when you do feel the need to upgrade.
