its my new FPB, a missile , torpedo, gun carriage. it based on 1:35 th scale..full paper and expanded polysterene.
-
its controlled by a toy R/C, so i used an indepentand motor control to this craft.it runs so fast, with toy motors, i replaced its armature windings to the specifications to 7.2 volts.and replaced its plastic back with brass bushes taken from an old car stereo cassete player.it can turn from a stand still within its lengts, can cruise with one motor, with a slight directional correctios, and drops only 700 Ma at full load.i replaced all motor driving transistors on toy R/C reciever board with D882, and D772 respectively to with stand a rough handling...after adding a RF booster circuit in front of the reciever antenna, i am getting a range of 600 meter square.

its props are made from zink sheet, and dia in to 1.5 inches.i placed the props 1 third to its length, so it turns well...
-
its deck based on my imagination, yes it is finished as a missile tow.. all by drawing paper
-
at front i placed a multi barrel cannon, with 7 barrels, 6 of them fires 12 mm self destroying traced shells, while a centered one the 7th will fire a 25 mm HV AP shell. while a 15 mm cannon placed at rear. all guns are guided. i have ample of work to finish it ..
