Not sure if anyone's interested, but here goes.

Hobby People is having a sale through tomorrow (looks like store-only, ends Jan 18, 2009, didn't know until today), and the M.A.S.H. helicopter (http://www.hobbypeople.net/gallery/163127.asp) is on sale for $80. This price includes a 4 channel 2.4GHz radio, receiver, LiPo battery, slow charger, probably a small ESC, and probably a couple micro servos. Oh, and a helicopter.

Could make for a simple, cheap-ish robot remote, once liberated from it's toy chopper confines.

Oh - I see "store only" now in your post. I was gonna say - it's $159 online - and I tried adding to cart too...

7hr drive for me one way, probably a bit more the other...

Yeah, definitely a drawback. Offensive, even.

And, apologies to all. I didn't realize until just now that it seems they don't have stores outside of Southern California and Las Vegas.

No promises, it's possible that a phone order (1-800-854-8471) might get the in-store deal.

I'm a spektrum fanboy....

you can get a Blade MCX for 130 bucks: http://www.horizonhobby.com/Products/Default.aspx?ProdId=EFLH2200 which includes this 4-ch non programmable tx which can be bought separately for a bit over 40 bucks: http://www.horizonhobby.com/Products/Default.aspx?ProdID=EFLH1064

you can get a 5ch non-programmable for about 100 bucks http://www.horizonhobby.com/Products/Default.aspx?ProdID=SPM5500

or a programmable 6 ch for 200 bucks http://www.horizonhobby.com/Products/Default.aspx?ProdId=SPM6600

One thing about 2.4ghz systems are that they are not all compatible. You can not use any 2.4ghz transmitter with any 2.4ghz receiver. They are unfortunately proprietary. So which ever company you pick, you are stuck with buying their receivers. Again, I am a spektrum fanboy, mostly because I've never had any problems with them, flying my rc helis and planes, as well as glitch free at radio heavy events like robogames and maker faire. But also they are the most popular 2.4 system, so parts are easy to get, with different options. If you need just a 4 ch non programable, than the one for the blade mcx will work for you, heck the heli is really a blast as well. But if you need a bit more flexibility, dx6i will work great. I use a dx7 for everything, having a bit of ability to tweak and program within the tx is awesome.... all of my bots uses it and spektrum receivers.

Thanks for the info, I didn't know that.

no prob... it's really dumb that it's not like the radio stuff, where everything is compatible as long as the frequencies match. Anyway, I don't know what really goes on in those little thingies, all I know comes from my r/c hobby... spektrum made the dx6 which uses DSM1, then came out with dx7, dx6i, and other transmitters in the links above, which now uses DSM2.... DSM2 transmitters will bind with DSM1 recievers, but DSM1 transmitters will NOT bind with DSM2 recievers. FYI, all of the links I had provided above uses Spektrum DSM2, and the 2.4 stuff from E-Flite, Parkzone, and JR are all compatible with Spektrum, and can use all spektrum 2.4 recievers, both DSM1 & 2 recievers. Comfused yet? I am....
