Gentlemen:
Please allow me to add some information to your interests in the RC world.
In the '70s there were seven 72 Mhz frequencies allowed for RC flying. 27mhz was available, however at risk. If near a highway or so it was not infrequently that your machine would perform a Lamshavock (sp. ? ) while the pilot was saying "I did not know I could do that!"
The CB radios took their toll of RC airplanes.
AMA was working for more and better frequencies. In about 1980, the FCC offered 50 72 MHz freqs. for model airplane only use, along with other freqs. (channels) for ground vehicles. Then a hangup happened. Some lower level FCC persons hung on to the freqs. The AMA Frequency Committee Chairman ( name is found as Technical Editor for AMA in the MA mag.) and I, then the AMA Dist. VI DVP -not on the committee- worked out something that the EC didn't like, but knew they should go along with. That was early November, 1981, and within a couple weeks the freqs. were released.
The 50 channels were released on a Phase-In plan to assist the industry to get production from a few wide-band channels to a lot of narrow band channels. FCC set the deadline as 1991. I don't recall the exact day, etc., but after that all new radio transmitters had to be narrow band. If you wished you could have your old one re-tuned, thus the sticker program. If you had a wide-band receiver in your machine, then you could easily get shot down. Your choice!
All clubs or groups needed a frequency board and much effort was expended these past 34+ years to that effect and still happens. I still fly 72Mhz as I have 3 excellent transmitters plus 7 others not so great, 2 being multi-frequency, and about 20 receivers, several multi-frequency. Not much problem as so few are using them. In today's world each has to have the latest item it seems so RCer spend fortunes on the latest radio, battery or super servos. They will pay whatever for the
Latest[/b new item but P&M loudly about AMA and Club dues.
]I have a dozen super digital servos in a drawer. Never been used. Regular servos still work fine and don't waste a lot of power, as digitals do. I have 4 2.4 radio transmitters, 6 receivers, and they seldom get used. One unit is for night flying only.
You don't need 2.4 to enjoy RC. One scale writer in a now defunct magazine was fired because he wrote to the RC Scale community that there was no need for the big expensive digital servos being advertised as the ONLY way to fly. If you have to go that route on your CL model, you will also need a bigger battery than you need for a small 42oz. analog.
OTOH, if you are right next to an RC field, I suggest you check out their fliers for 72mhz. if within a 1.5 miles.
My RC Warbird model, Eiendecker, my main entry at area warbird fly-ins for several years has 101" wingspan, fabric and dope, Zen. G-26 gas burner. Flies well. No digital servos, Channel 51. Picture not accepted here.
