Why did you start a poll?

Your image is too small to really read.

You make no mention of the specifications for the power supplies you are using? You also do not provide the motor specs? This would go better with a complete circuit posted and all the specs provided.

More information is needed about your set up, but if you are using regular hobby receivers there output is only a 1 to 2 ms pulse and is not suitable to drive the motors.
