A part of the review has been auto-translated.
the remote is very strong built. The x4fmg receiver is small. It has some bugs but hopefully they will be solved with an update . For example the RSSI does not update real time while on main screen.
I discovered the DDF 350 on YouTube. The many settings, the price, and the appearance convinced me. When I recently bought the ROG1 and the XTS-F10 from rlaarlo, I thought it was time to buy this remote control. When it arrived, I was very happy and of course wanted to try it out right away. Not wanting to wait long, I unscrewed the receiver box from the ROG1, hoping the existing receiver could connect with the DDF 350. I was lucky. After all, rlaarlo's cars are equipped with remote controls from Dumbo RC. So I quickly adjusted a few settings, which was quite easy because the menu is intuitive and can be set to German. Finally, it was time to hit the track. Everything worked without problems, the remote control feels good, fits well in the hand, and does what it's supposed to do. For that, there is a clear purchase recommendation.
