Protect Wheels with Steering Stops How to Measure Droop for Setup Sheets Slim Alloy Wheel Hex Problem
We’ve been really enjoying the Schumacher Neon and wanted to share some setup tips we’ve been asked about recently. This chassis is a completely new concept for MTC racing, and being its first generation, there are bound to be a few teething problems. Thankfully, we haven’t encountered many, and the performance has been outstanding.
Here are a few areas we’ve had questions on and thought it would be helpful to share with you.
Pro Tip 1: Protect Wheels with Steering Stops
One issue some racers have faced is broken wheels, which can occur when the steering turns too far (or is pushed from impacts) and hits the wheel. This damages both the wheel and the wishbone.
To prevent this, you can fit servo mounts to the top of the steering arms, as shown in the image below. This simple modification will act as a steering stop, protecting your wheels and wishbones from damage.
You will need the following parts for this setup:
- U3498 - Schumacher - Ball Studs; X-Long - pk 4
- U4327 - Schumacher - Alloy Servo Mount Black
- 10mm M3 screw
Pro Tip 2: How to Measure Droop for Setup Sheets
Schumacher drivers generally use the Aerox TC Droop Tool to set the droop on their touring cars, including the Neon. These are the same settings you'll find on Schumacher setup sheets.
To measure droop for your setup sheet, you’ll need the following:
- AX014 - Aerox TC Droop Gauge Blocks
- AX015 - Aerox TC Droop Gauge & Disks
- Flat Setup Board
How to check droop on Schumacher Neon MTC
- Remove the wheels and place the chassis on the Droop Gauge Blocks.
- Ensure the blocks are flat to the chassis and avoid any screws that might affect the measurement.
- Fit the droop discs onto the axles where you normally attach the wheel nuts. Don’t tighten them, so they can spin freely on the axle.
- Slide the droop gauge under the disc, starting from its lowest 20mm point.
- When the widest part of the disc touches the gauge, that’s your droop measurement.
Recommended Starting Droop for Schumacher Neon MTC
- Front: 21mm
- Rear: 20mm
Problem When Using Slim Alloy Wheel Hex with Rush Wheels
If you’re running the Slim Alloy Wheel Hex (U3470) with Rush MTC wheels, be cautious, as this combination could cause the wheels to rub on the hub. The issue arises because the slim wheel hex is not thick enough to work properly with the wheel hex on the Rush wheels.
Through testing, we found that Ride wheels fit perfectly with the slim alloy hexes, so if you're looking for a reliable alternative, they’re worth considering.
However, if you already have the slim hexes and want to continue using Rush wheels, there’s a simple workaround. You can use the Disc Spring Washer (U2184), which came with the original hexes, to shim the wheel away from the drive hex. Keep in mind that this solution will slightly widen the overall width of the car, so make sure it complies with your race regulations or personal preferences.
