For many years, I have been fortunate enough to be sponsored by Futaba. Futaba is a good radio and there are many other fine radio systems as well.
Last summer the technical writer preparing the operation manual for the new Futaba 3PK contacted me regarding what needed to be included in the manual for model boaters. This presented me with an interesting situation. I probably use 10% of the capability of my 3PJS. The model memory feature is great and I like the third channel for onboard mixture control. The other features I use - servo reverse, servo trim, and rate for the rudder are available on the less expensive Futaba Magnum, Jr. After reading my responses to the questions presented regarding the operation's manual, the technical writer probably thought, "Jeez, and we give this guy radios??!!"
Doing product reviews for RC Boat Modeler, product development for major model model distributors, and just helping guys with their boats has allowed me to try a variety of radio systems. I find I drive just as well with a basic 2-channel system as I do with my 3PJS. In my opinion, the biggest upgrades in recent years has been the development of more powerful servos.
However, I will say radio systems have come a long way since I bought my first 3-channel reed system back in 1965. How many of you guys reading this post ever operated a model boat using a reed transmitter? Hell, probably half you guys weren't even born by 1965!!
