Here's an old story, a long time ago when 2.4 came out for cordless home phones they sucked, when me and my buddy use to call eachother to figure out where to meet up on our dirtbikes and where to ride we got a lot of static and poor range. You just couldn't talk about going riding in ileagal areas infront of your parents ya know! So we unscrewed the standard antenna and installed a R/C antenna from our R/C car TX's, yes the old 2.4 cordless phones came with screw in collapsable antennas. Well, as we were B.S.ing about where to ride and what to do, he walked out tward his parents shed and I overheard his neighbor talking on the phone, when he identified who it was, it was his girlfriends mother talking about how she didn't like her hanging around with him. The funny thing is, they lived 1/2 mile away. Go figure, safe, secure 2.4 isn't so. I think most of the problems with 2.4 are due to poor R&D or programing on the manufactures side. But everytime I log on to RCU, it seems like someone has an incident with the 2.4 systems that is unexplainable, just doesn't give me a warm and fuzzy feeling about putting it in one of my hand built planes that took me 1/2 a year to cut and assemble just to watch it take off on it's own with no control.
The other thing that boggles me is how do you range check a 2.4 system? They come with a rubber ducky antenna, right? In the 72MHZ world, you walk 33 paces, aprox 100 feet, away from the model with the antenna down, if you still have control of the aircraft with no gitters, then the range check is complete and satisfactory, how do you do it with a 2.4? can't collopse the rubber ducky now can you, just hope for the best and take off, or do we wait idling to see it it takes off on it's own?
