My understanding of the FW/RW Instructor debate is that Stuckwing instructors get very little per hour but nearly always get a retainer which condsiderably enhances their perhour rate.
Eggbeaters on the other hand get paid per hour only with very few on retainers so no flying means no pay.
I have left instructing(H) for a while as there are far too many people in the industry at the moment with little chance of making a reasonable salary.
Good luck all who persevere!
