Rc plane

i build rc plane arduino nano + nrf (2 servo , 1 esc) esc put in a3 , servo1 in a0, servo2 in a2 .. servo employed, while esc not work .. maybe wrong write value or sketchnya .. maybe guys can me mistakes

// transmitter

#include <spi.h>
#include "rf24.h"
rf24 radio(9,10);
const uint64_t pipe = 0xe8e8f0f0e1ll;
int msg[1];
int potpin_1 = a0;
int val_1;
int potpin_2 = a1;
int val_2;
int potpin_3 = a3;
int val_3;
void setup(void){
radio.begin();
radio.openwritingpipe(pipe);
}
void loop() {
val_1 = analogread(potpin_1),val_1 = map(val_1, 0, 1023, 0, 127),msg[0] = val_1,radio.write(msg, 1);
val_2 = analogread(potpin_2),val_2 = map(val_2, 0, 1023, 128, 255),msg[0] = val_2,radio.write(msg, 1);
val_3 = analogread(potpin_3),val_3 = map(val_3, 0, 1023, 10, 10),msg[0] = val_3,radio.write(msg, 1);


}


and receiver

//

//


//
#include <servo.h>

#include <spi.h>
//

//

#include "rf24.h"
servo servo1;


servo servo2;


servo servo3;


rf24 radio(9,10);
const uint64_t pipe = 0xe8e8f0f0e1ll;
int msg[1];
int data;
int pos;
int throotle =50;
void setup()
{
servo1.attach(3);
servo2.attach(4);
servo3.attach(7);
radio.begin();
radio.openreadingpipe(1,pipe);
radio.startlistening();
}
void loop()
{
if (radio.available())radio.read(msg, 1);
if (msg[0] <128 && msg[0] >-1)data = msg[0], pos = map(data, 0, 127, 0, 177),servo1.write(pos);
if (msg[0] >127 && msg[0] <255)data = msg[0], pos = map(data, 128, 254, 9, 177),servo2.write(pos);
if (msg[0] <0 && msg[0] <255)data = msg[0], pos = map(data, 0, 1023, 1000, 3000),servo3.write(pos);

}

code: [select]

val_1 = analogread(potpin_1),val_1 = map(val_1, 0, 1023, 0, 127),msg[0] = val_1,radio.write(msg, 1);

that's not how write c++ code.  why don't rewrite readable before ask read , out it.  1 statement per line.  can't jam commas , no spaces , expect parse through it.
