RE: 2.4 ghz module
Until it is released it's all a guessing game, so I'll make a guess.
Not that it applies to Hitec in any way but here's some speculation based on the competition.
The Spektrum 6 channel park flyer receiver is $60 and some of the 2 & 3 channel surface receivers are about $100. Their 2 & 3 channel surface transmitter modules sell for $110 to $130.
I guess I'd expect a full range 9 channel receiver to cost between $120 & $200 and a matching transmitter module to be $220 to $260 (about double what the short range stuff with less channels sells for).
I hope this stuff comes out soon and works great. I hope "everyone" gets rid of all of their 72 mhz equipment. Then I'll be able to fly on channel 49 with no fear of being shot down by another transmitter.
