I have the opportunity at an FBO that I part-time work at to do a sales-leaseback of my PA18. The reason for considering this proposal is so that I can instruct in the PA-18, basically doing tailwheel endorsements, under the FBO's insurance umbrella. Under this Sales-leaseback proposal/agreement, I would have the ability to set the rental rate for the PA-18, and the hourly instruction rate. My question is, What's the market rate for a PA-18 rental? Again, the rental would be with only myself instructing in the plane with the student. The students would never get to solo in the plane. In my state there is a J3 and a Pacer that are available for this type of rental use, however their aircraft rental rates are around $150/hr. From what I've previously researched in Alaska, a PA-18 rental rate is $250/hr, or more, plus instructor. I can't find any other Super Cubs for rent in my state for this type of rental/flight instruction. So from a market perspective, part of me says I need to be competitive and charge a rate around $150/hr. However, due to the Super Cub having a much higher hull value, and more performance than the J3 and Pacer, I should be able to charge a premium. Any thoughts on rental rates for a Super Cub would be much appreciated.
