The answer to your problems lies with the full scale solutions. Although new to RC flying, I am a private pilot in small engine aircraft. Whilst purchasing a new pilots logbook I noticed that the little pilot handbooks were just as detailed and easy to use so I have purchased a small pilot logbook for around $5.00 and it has ALL the information you need in an A5 size book which is easy to carry to the field. You can find a small logbook for little money that suits your specific needs. It also leaves the option open to keep track of either your flights on any plane or any pilot on any plane. The options are unlimited.
Best of luck,
Paul Man
