Hello everybody, I'd like to share with you a little project I started a few (hmm.. six including R&D phase ) months ago - scratchbuilt radio controlled Leopard 2A4 in 1:16 scale. The assumptions for my build are as follows: 2mm thick aluminium body with resin details, polish markings elmod control module with Turnigy 9x stabilised gun fully regulated suspension, relatively high water resistance very high mud resistance camera I guess I won't be able to meet all these targets, but even 80% will be good enough for a RC rookie. This is my first RC model (before I was building paper tanks...) so I had to start with basics - learn how this all electronic stuff work. Second step was a CAD project which allowed me to cut most of aluminium parts on waterjet machine. This way I created the set of parts which was glued together with epoxy glue. On the photos below you can see the current status of my Leo. Feel free to any questions. |

If this is the basic work of a Rookie I would love to see the work of an Expert. It looks better than the Tamiya Kit, Well done. Looking forward to more photo's and video's Cheers Graham |

Hi, A little update - I made a test and checked the suspension setup. It doesn't look bad. Some fine-tuning should fix the level after final assembly. In the meanwhile I also flashed Turnigy 9x. Thank you |

Hi, This week I was able to run the first fileld tests. Below a short (and poor quality...sory) clip showing the performance of the chasis: I also wanted to check the strenght of the motors, but since I had no proper hill for this kind of test I had to borrow one of my wife's tools My model's weight at this point is about 6kg. |

Hello everybody, After a long pause I'm back - in fact I got back from a 3-month business trip before the Christmas, but well - there was nothing to report after such a long absence Now I can show you what I was able do build despite the multidude of other task waiting for me at home. I added some details to the turret and painted (primed) it to check if everything goes fine. Of course it doesn't - so I'll have to fix a few fake welds My travel was for me also an opportunity to "upgreade" this project a little. There are several items in my drawer which will for sure make it more interesting - FPV equipment and automatic pilot (Ardupilot) If I'm lucky (and smart) enough I'll have a real HUD... |

Small test of turret rotation mechanism: https://www.youtube.com/watch?v=NZjta-_pIaE It seems like my little trick works - barrel do not hit the rear deck I also managed to install FPV with some extras, here is the result: And this is how the turret interior looks like at the moment: |

Though I'm into the old WWII tanks myself, & I actually don't care for modern tanks much at all, I can't help but admire your extremely fine craftsmanship on this tank ... the results of all your hard work & talent has created a real beauty, something to make one proud indeed!!! Thanks for sharing. ~ Craig ~ |

Hi, It has been long time since I last did any progress here The project is frozen - generally due to insufficient power of motors which I used and inadequate workshop to replace them with a proper brushless pair (and resulting motivation crysis, which I had to overcome). Brushed motors with the gear ratio I used are capable to easly achieve correct ahead/reverse speed, but one is unable to make the 8kg model turn Turning radius in rough terrain is like 2 meters Meanwhile I decided to fix the core probem so instead of struggling to "revive" this model I was working to improve my workshop - I found some free space, learned a lot, built my own cnc mill, bouht lathe and some other "hardware junk". I also tested it all building another, easier tank - T-34 - http://rctank.pl/forum/viewtopic.php?f=62&t=818 But Leopard still has "frozen" status. I intend to continue the idea, just with a different approach Now I have easly available Heng Long Plastic parts. I want to use the plastic hull and metal upgrade parts (wheels etc.), but scratchbuild the whole interior - replace the gears, create the watertight compartment for electronics etc. The rest of assumptions (FPV, stabilisation) remain the same Recently I made a set of inserts strenghtening the plastic hull for one of colleagues. Next step - should not be so difficult |
