Yes Hardrock, I'm a maniac but here i'm in good company! The best forum with the best people, still a tad frustrating for my photos posting issues. Have you seen my 1/350 Shchuka-B conversion? Posted it on RCG at peak of photo issues frustration https://www.rcgroups.com/forums/show...ula-conversion that was mad work and it was debugged lately. And i never shared the saga of my micro video submarines, now coming at the fourth, and i hope deefinitive, iteration. They are based on the usual 3CH non proportional set and Denver AC1300 action cam wich is decent, small and cheap. Also, there is a hope for the shelved Kya project: to rig a centrifugal bilge pump so that it drains the exterior hull from water, once the submarine is brought deck awash by the piston. To dive, simply invert polarity and the piston tank will begin to fill and the reversed bilge pump will flood the exterior hull. Hope that water viscosity and a powerful 6mm drone motor for bilge pump will help. Naturally this coreless motor magnet and solid coil system makes rigging a double rudder for 1/144 VII quite easy!
PS: Did you know that there is a 1/144 Permit class model made by an ukrainan company named Modelsvit? Hull is almost entirely made in hollow glass fibre with just the stern, tailplanes and sail made in styrene. Ordered it a couple of weeks ago, will report when it arrives.

You are a maniac. Admittedly, you are a brilliantly innovative and highly skilled maniac - but still a maniac. This is great!Leave a comment:

USS Haddock SSN 621 in 1/350, 2,5 CH conversion
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=CNLast edited by zhuravlik; 12-21-2017, 07:18 PM.
