Mustang Bob...
If you fly off paved surfaces no need to change gear.. if you fly off grass...then I cannot speak from experience..
Remember the KISS method... Keep it simple s.....!! Just run the 40 LA's as we spoke...run them side mounted with the pitts mufflers... IF you want to spend the $$$ then go for the .46 LA's/// But 40 LA's are a great combo and are a good speed in the P-82..THanks for asking..
