Hello lads,
Last year i made a simple test rig to test the coreless motor magnet and solid coil idea so i took an old 1/350 Los Angeles model hull, survived from a previous motorizing experiment (I was eleven years old..) and used it to mount everything upon it. Did a small 7 blade prop with alu can and turned plastic and took a 4mm x 8 coreless motor to turn it direct drive. Wayyy overpropped, i know... Used a coil from a small rc car and a magnet from a 6mm coreless motor to swing the rudder. https://www.youtube.com/watch?v=4BHxKpIHt50 It worked so well that i decided to test in water so i sawed the poor LA hull to match short hull Permit class because I realized that I could kitbash a LA sail into a Permit long sail. A small USS Haddock was born! Unfortunately the small motor couldn't push it under the waves, even with 0,5mm from sail top waterline. Now i should mention that the motor is mounted with a slight donward thrust line. So the project was temporary shelved until, a week ago, i found that you can actually add a turbo mode in those small 2 CH TX/RX. All you have to do is to solder a button between GND and turbo mode pin on the TX IC so if you push it , RX gives the whole battery voltage to the motor. Now it merrily disappears beneath the waves in the lenght of a bathtub with turbo button pressed and can maintain depth with normal fwd button So I'm prepping it for a primer shot and adding essential details such as those ears on the sail and various warts and bits. Will rebuild the stern dive planes with soft wire and use a 20 ml syringe as a WTC to retain the piston at the front end assist with fine tuning and water density variations.
With this RX/TX it's possible to convert almost all 1/350 submarines if one is happy with controlling depth with speed control: RX is just 22mm x 18 mm and comes in three different channels to play together. https://www.banggood.com/Wholesale-3...r_warehouse=CN
