Hey, very great job. I see that you use Sanwa RX-40V/92134 and it has a frequency of 2.4 GHz, and everywhere they write that it is not suitable for submarines, it does not penetrate water, that the better frequencies are 40 MHz, 433 MHz, 868 MHz, 900 MHz and etc. What is it with the 2.4 GHz frequency???
THIS IS THE 1/200 SCALE OF A GERMAN U-9 U-BOAT MODEL OF NICHIMO. IT MAKES THIS MODEL BECOME RC MODEL. I CAN USE THIS DIY TECHNIQUE TO OTHERS SUBMARINE MODEL WHICH ARE MUCH LARGER SIZE. THEY ARE U-7 U-BOAT MODEL OF 1/144 SCALE, TEMPETER U-7 U-BOAT & GATO CLASS MODEL OF 1/72 SCALE, REVELL
