Features looking for: 10 or more model memory, 3 or more channels, ABS, Long battery life, Reliability, Range, Feel of the radio, Trim, Trim Rate, Reverse, Dual Rate, End Point Adjustment (EPA) Left/Right, Exponential, Sub Trim, and Speed Turn/Return. I want to stay under $250. I want this to be the last radio I buy!
DX4S has 30 model memory, 4 channels, ABS, Long Battery Life (with several different chemistries supports), Reliability, Range, great feel (3 different grips come with it), Trim, Trim Step Size, Reverse, EPA (we call it Travel), Expo, Sub Trim, and servo speed adjustments. MAP is only $279.99 so I'm sure if you do your shopping you'll find it a little closer to your target (but it won't be advertised - you'll have to put it in your cart or ask the retailer to hit your target). Looks like you found your new radio!
Here's the manual: http://www.horizonhobby.com/pdf/SPM4...al_English.pdf
BTW, it also features our intuitive programming system, so you'll be right at home there too.
