Sold on aliexpress, where the fabricator got their webshop. About 2000 usd incl freight for the excavator. Did import and sold 3 off the 'RTR' 954 over here in Europe last year. Assembled by amatures, hydraulics was crap, except cylinders okay. After a couple of months we ripped out the hydraulics and replaced with Premacon equipment, 1000 usd. Still a relative cheap machine. The frame structure is good, all steel plates, track motors fine. They are sold at RCbrimin as a kit without the valve and pump. That's where I got number 4, which I assembled myself with Premacon hydraulics. Used the 900 ml pump, but will for future builds use the 1200 ml version instead, tune down max speed to get lower rpm/more quiet operation.
