Product Description
Wheel Extension and Drop Down for KO Propo Helios Ex-10, KO Propo EX-10 Euros, and JR Racing Z1 racing transmitter.

These are popular for racing Mini-Z's as well as being a solid radio in the 1/10th and 1/8th racing arena.

Design Concept-
The multi-angle wheel extension that is available works fine but I had 2 main issues with it.
1) I never use the angle feature and the way it is designed there is a possibility with use over time or just some hard steering in the heat of a race the wheel can shift and that is unsettling. It is also an extra 2 screws for dis-assembly which leads into...
2) The transmitter with the wheel extension is HUGE. It's fine if you race locally and have a big case to carry it in or just drive it around on the passenger seat but any kind of travelling (especially flying) with it is cumbersome. For a while I used a ball end wrench to get the 2 screws behind the steering wheel and took the other 2 off the main unit to store them separately when travelling but then the wires from the steering unit were just out and the PCB on the transmitter were left bare... To keep the PCB protected I would have had to take the entire extension apart (10 screws).

Hence my design. I did away with the tilt-angle since I didn't need the feature and honestly can't say i've seen too many racers use it... And also I made the extension more modular. The wires can be accessed by removing 1 screw and lifting the cover off. The steering unit is tied to the main transmitter by 2 50mm M4 screws. Remove them and the whole steering unit is now in your hand with just the plugs to deal with. There is plenty of room to tuck them into the case if you wish. As for the main unit just put the cover back on the PCB is covered and protected.

Assembly-
Screws are not included but if i start getting requests I may start selling the screw kit as well to help customers of this set. I highly suggest tapping the holes as it will make the product last a long time and allow for a lot of assembly/dis-assembly without stripping the plastic.
You will need:
4 - M7x0.7 14mm length Socket Head Cap Screws (You can re-use the stock screws but they are a coarse thread which may be hard to get a tap for and using them directly into the piece may damage the plastic)
2 - M7x0.7 50mm length Socket Head Cap Screws
1 - M3x0.5 8mm length Socket Head Cap Screws
Suggested Thread Taps: M3x0.5 and M4x0.7
