Interceptor E that I have flown are fine on an E9 4, stock built. Even in a bit of wind. My local club is kaput so I just stare at my big motors sitting on the shelf. Then I harken back to the old fraternity days and yell out ROAD TRIP! Pack up the old convertible and off I go to wherever a launch is being held. Get out to the remote gravel pits, ranches and BLM land. See lots of other old Dudes doing the same. Has been keeping me somewhat sane during these troubled times. Burned more big motors this year than ever before. Can't spend money on theater tickets, fancy partys, pro sports, high end clubs or restaurants, so rocket motors and gas it is for entertainment.
