The MR33 Circle Droop Gauge V2 makes measuring and adjusting the droop on your 1/10th scale touring car or FWD model more precise than ever before!
Why is that?
The two small (and very practical integrated in the Droop Gauge) aluminum wheels are screwed onto the wheel axles of your vehicle.
The suspension travel is then measured at the lower edge of the aluminum wheels.
The measurement is then more accurate because you always measure at the center of the wheel axle and tolerances in wheel carriers, wishbones and other components of your vehicle no longer play a role.
How do I compare the values with my "old" Droop values?
The new MR33 Circle Droop Gauge V2 is graduated in 0.2mm steps and has a measuring range of 21.0 - 25.0mm.
In order to compare these values with the conventional old known suspension travel of your current vehicle (e.g. 4.0 or 6.0), you simply have to carry out a comparison measurement. You can then write these values in a small table, for example, so that you always know quickly on the racetrack how to compare the values of the "new" gauge with those of the "old" gauge.
What is included in the scope of delivery?
MR33 Circle Droop Gauge V2
2 bolt-on aluminum wheels
What else is needed to measure the suspension travel?
10mm droop blocks on which the vehicle is placed during the measuring process (e.g. MR33-DB)
What is "droop" (suspension travel) on an RC car?
Droop describes how far the wheel can rebound downwards when the car jumps over a bump, for example, or is unloaded (as when rebounding after a bend).
Technically speaking:
? Droop = difference between compressed state and maximum extended state of the suspension.
Less droop (less suspension travel) → Limited wheel travel downwards
More droop (more suspension travel) → Wheels can "drop" further downwards
Droop is usually measured:
-
Via the length of the damper (damper travel) or
-
Via the droop scale on the control arm (e.g. with a droop gauge or the MR33-CDGV2)
How does droop affect handling?
Here is the really important practical overview of what less or more droop does in each case - separately for the front and rear axle:
| Droop setting | Front axle | Rear axle |
|---|---|---|
| Less droop (less suspension travel) | - Less front roll - More direct turn-in - Less weight transfer to the outside (smoother) |
- Less traction on corner exit - More stable under braking (less nose-dive) - Less oversteer |
| More droop (more suspension travel) | - More front body roll - More grip at the front (more biting turn-in) - Car becomes "cheekier", can become more unstable |
- More traction on the rear axle - Better ground contact on uneven roads - Can tend to oversteer (rear "comes faster") |
Simply put:
? More rear droop = More rear traction, better on bumps
? More droop at the front = more aggressiveness when turning in (but be careful: more unstable)
How do you adjust droop?
Classic method (e.g. for 1:10 Touring Car)
- Adjust the droop screws under the wishbones (stop screws)
- Attach the droop gauge → measure the height
When do you change droop?
| Track condition | Recommendation |
|---|---|
| Smooth carpet | Less droop (car flatter, more stable) |
| Bumpy track / outdoor asphalt | More droop (better ground contact) |
| Lots of high speed (long bends) | Less rear droop (more stability) |
| Technical track (tight bends) | More droop at the front (more aggressive steering) |
