I've seen this sweet drop down wheel on many of the Team Losi racers DX3r radios. I was told this would eventually be available for the public by one of the team drivers. But this was about two years ago. I held the radio and it was really a nice improvement. The drop down wheel basically puts the wheel closer to the same axis or just bellow the axis of the throttle. The drop down wheel adapter is made of a lightweight material so the radio is still lightweight. I can say without a doubt- if this drop down wheel was available for purchase, I would buy it for my DX3r radio in an instant. In fact, if the drop down wheel adapter was available for the DX3r, I wouldn't be looking for a different model radio right now. I've specifically been looking at radios which have the drop down wheel adapter- as an option to purchase.

PS. I was most recently told that there are no plans for Losi to release the DX3r drop down wheel adapter to the public- but that could always change if demand for the DX3r drop down wheel adapter became overwhelming. I'll post a picture of the drop down wheel adapter onto this thread first chance I have. I've considered trying to make one or have one made, but have decide to purchase a new radio which already has the drop down wheel adapter made for us to purchase.
