DrJimbo Posted August 2, 2021 Posted August 2, 2021 (edited) Hi folks, I am working on a generic tank, based on a request from my son. Inspired by the many shades of green provided by Lego, I have gone for a camo approach, supplemented by black & DBG where needed. Aims for the build were to have something fun for the kids to play with, that looked like a tank, with tank drive, turret rotation and elevation, and ability to shoot. Still working on the last part. The LandRover is providing a lot of the panels, beams and plates. I plan to close the front corners of the turret with 21/22 panels, but waiting for final barrel design. Openable rear to house battery box. Buwizz / CADA compatible, using CADA for now. Bottom is fairly enclosed, this drives well on grass: Drive is by 2 L-motors, pretty much directly connected. Simple and effective. I could try CADA L-motors and Buwizz battery for lots more power. One issue is that this is a far from modular build, so very difficult to take apart even for photos, let alone rework. Two M-motors in the middle of the chassis drive turret rotation (full 360) and barrel elevation. Again, pretty simple linkage. Adding a cockpit for the minifig commander, with opening hatch, ended up with a pleasing result. There are additional crew in the back, but these may need to make way for a second battery for a firing mechanism. The LandRover mudguards work really well here, I think. The current firing mechanism was to be a manual pull back, with a catch, that releases technic springs. This really does not work, so I am looking at some other options described in videos out there. In any case, I realise this needs to be mechanised anyhow, since there is no point having an RC tank that you need to walk up to to fire. I just hope I can find something that works at this scale. I appreciate this is quite crude, and probably reveals its 'make it up as you go along' design choices, but I am quite satisfied at how well it drives and funcitons and it pleases the target audience - I just need to finish that firing mechanism!

Jeroen Ottens Posted August 3, 2021 Posted August 3, 2021 Looks like this could be a lot of fun for your son if you get that firingmechanism to work. The colourscheme is certainly creative The turret is quite boxy though. Modern tankturrets are more trapezoid shaped. Quote
