How do you know if a receiver, controler, servo is good by just looking at the specs? Like what does MHZ do, and stuff lol. Basicly i wanna know what specs you look for. Thanks

A lot of people start with a brand preference first then look at specs from there. I used to run Futaba, that is until the JR XS3 came out. I couldn't wait to get synthesized.

Specs I look at.
TX - FM, only way to go for electric and especially nitro. PCM just isn't as prevelant in surface radios.
RX - Easy for me, the JR RS300 (and soon the RS310) because it's the synth rx that goes with the XS3 radio.
Servo - Although not real popular amongst my fellow racers, I use Hitec servos.
1/10 steering - Hitec HS-5925 digital high speed/good torque steering servo
1/10 throttle - JR Z590, good speed/good torque. Came with the XS3 radio as a steering servo.
1/8 buggy steering - Hitec HS-5945, digital high torque/good speed.
1/8 buggy throttle - JR Z590, same as above.
1/8 monster truck steering - same as buggy
1/8 monster truck throttle - same as buggy

As far as specs go, here's what I follow.
1/10th steering - 70+ oz of torque and as fast as you can afford.
1/10th throttle - 50+ oz of torque unless you're running a lot of aluminum parts and need better brakes, then up the torque to 80+.
1/8 steering - 100+ oz of torque and as fast as you can afford but torque is more important because of the weight of the vehicle.
1/8 throttle - 80+ oz of torque, again because of weight, you don't want to come up short on brakes.

Gotta say the new JR XS-3 PRO is bringing be back 'round...I was starting to lean more toward the Airtronics MX-3S!!!

It's not even on JRs site yet, but there's a big ad in the new RCCA. It's basically the same, but with better servos, a MICRO Rx, adjustible trigger, and a much cooler whitish color (black is just SOOOO old!!!!).

It'll sticker for $249, only $10 more than the regular, but maybe this means they'll be lowering the price on that one!!!

Silver is the color.

Whats a good receiver and controler? I'm willing to spend about 100$ on a controler and about 80% on the receiver.

From your #'s it looks like you would be willing to spend $180 on a Radio.

You can pick up an XS3 on eBay for around that. RX, TX and 2 servos.

It's an awesome radio. I'll be switching to the XS3 Pro when it ships, though. I've had one for close to a year now and use it to run all my rigs except the micro's because, I've run out of model memory.
