Overview
The Reedy Power RT3507A is a low-profile, high-voltage brushless servo designed for 1:10 racing where space and weight are at a premium. It suits both off-road and on-road competition cars that need a low-mounted servo with fast response and high holding power.
A brushless motor, steel gear train and precision ball bearings are housed in a full CNC aluminum case with an integrated heat sink. At 7.4V it delivers 389 oz-in (28 kg-cm) of torque at 0.08 sec/60°, rising to 486 oz-in and 0.065 sec/60° at 8.4V, and it uses a 25-tooth output spline.
Key Features
- Brushless motor for fast, efficient response
- High-voltage operation from 6.0V to 8.4V
- Low-profile case for low center of gravity mounting
- Steel gears for durability
- Precision ball bearings
- Full CNC aluminum case with integrated heat sink
- 25-tooth output spline
Performance Benefits
- Low-profile layout keeps weight low in the chassis for improved handling
- High speed gives quick, precise steering input on technical tracks
- High torque holds steering angle under load on high-grip surfaces
- Aluminum case with heat sink helps manage heat during long runs
Usage Notes
- Best suited to 1:10 scale racing – on-road touring cars and pan cars, and 1:10 2WD/4WD off-road buggies and trucks with low-profile servo mounts
- Can be run directly on a 2S LiPo (7.4V/8.4V) receiver supply or an HV BEC; confirm your ESC/BEC and receiver support high voltage
- Check that your chassis accepts a low-profile servo (40.8 x 20.2 x 25.6mm) and a 25T servo horn/saver
