ADX 390

Looking for an incredibly powerful, yet lightweight engine for your UAV application? Look no further than the boxer four-cylinder ADX 390ccm engine. Based on the tried-and-true ADX 195 twin engine, the ADX 390 is packed with incredible power that will take your UAV to new heights.

But what really sets this engine apart is its weight - or, should we say, its lack thereof. With an unbelievably low weight, the ADX 390 delivers maximum power without weighing down your UAV. And now, with a CNC-machined crankcase, this engine is even more rigid and boasts even lower vibrations than its predecessor.

Don't settle for a heavy, underpowered engine for your UAV. Upgrade to the ADX 390 , boxer four-cylinder 390ccm engine and experience the ultimate power and lightweight design combination. Contact us today to learn more about this game-changing engine!
