Apex RC Accessories: Pick the Right Cable, Straps, or AUX Switch for Your RC

If you're working on an RC project, the accessory you choose depends on the exact job: replacing a sensor cable, securing a LiPo battery, or adding a remote-controlled function. Apex RC Products has four affordable parts in that space, but they aren't interchangeable. The right pick comes down to your radio setup, battery size, and space inside the chassis.

Quick take

These four Apex RC Products parts range from $7.99 to $11.99. The sensor cable pack is at the low end, a five-strap battery set sits in the middle, and the AUX channel switch plus the longer strap set share the top listing price. Decide by job: cable replacement, battery hold-down, or remote-controlled accessory switching. If you want the cheapest part in the group for a sensor-wiring task, start with the cable pack. If you need to secure a battery, move to the strap comparisons below. If you want to control lights, smoke units, or other extras from your radio, the AUX switch is the one that changes how the vehicle operates.

Product notes

Apex RC Products 70mm Silicone Brushless Motor Sensor Cables - 3 Pack #1040

The three-cable pack gives you spares for brushless motor sensor wiring, and the silicone insulation keeps the bundle flexible in tight spaces. The 70mm length is compact, which is great when the motor's sensor port and ESC are close together. This is a sensible start if you only need to complete that wiring job. The fixed 70mm length is the main constraint: if your route needs more reach, this cable won't stretch, so you'll have to re-route around the sensor wire path.

Apex RC Products 16mm X 200mm HD Rubberized Battery Straps - 5 Pack #3020

These five straps fit most 3S-4S LiPo packs and most 250mm FPV racer batteries. The rubberized 16mm by 200mm format gives you a firm hold without a lot of loose strap to tuck away. Having five straps in the pack means you can keep extras in your pit bag for battery changes. The 200mm length is the limiting factor: if your battery gets wider or the frame needs more reach, you'll want the longer strap set from this same line.

Apex RC Products RC Remote Electronic AUX Channel On/Off Switch #9025

This switch turns lights, smoke systems, bomb drops, or plane canopies on and off from your radio using any spare channel. It weighs only 7 grams and measures 30 x 13 x 3mm, so it fits into a small cavity without crowding other electronics. It installs inline with the accessory you want to control, but your radio needs that channel set to +/-100% throw. Without that setting, you won't get clean on/off behavior, and without a spare channel the switch has no accessory to control.

Apex RC Products 20mm X 300mm HD Non-Slip Battery Straps - 5 Pack #3031A

If the 200mm strap is too short, this five-pack gives you 20mm by 300mm of non-slip surface. The double stitching at the buckle is the durability detail, and the wider profile spreads pressure over larger packs. This is the right choice when your LiPo needs extra strap length or when you want more margin to route around wiring. The trade-off is the extra material: in a compact 250mm racer, 300mm can feel like more strap than the chassis needs.

Final recommendation by use case

For a direct cable replacement, #1040 covers you with spares. For a typical FPV battery, #3020 is the natural fit. For remote-controlled accessory switching, #9025 is the one to buy. For a larger LiPo pack that needs more strap, go with #3031A.
