RE: another "fly without an instructor" question
You've answered your own question. Without an instructor, you've crashed plane after plane, time after time. A foamie is much lighter and slower (read less stored energy) than the Nexstar. A crash that will put a foamie out of commission for a couple of hours worth of repairs might well destroy the heavier, faster Nexstar. You've already found that electric foamies can be expensive, don't find out that crashing the Nexstar can be even more expensive.
Simulators are good, but VERY much different than real life, and NOT a good substitute for actual, personal instruction.
Be patient, wait until your instructor is available, or find another instructor to help you. Many soloed R/C pilots learned with more than one teacher.
