I have a saito 40 waiting for the post man to bring me my magic. I am going all mini metal gear servos, JR 610 micro reciever, and a 720 mah Nimh RX pack (2.3 oz). I am shooting for 3.5 or if I am in God's good graces a smidge lighter. I should have it togeather next weekend and a flight report will follow.
