Laser 70

Description

Laser 70 bearings from RC Bearings are a standard replacement set for modelers who want dependable, full-power performance from their engine. Each set is made to our own strict specifications with top-quality parts, and we hold clearances and tolerances tight so your engine runs smoothly and consistently, flight after flight.

What Makes Our Laser 70 Bearings Different?

Worn bearings are one of the most common reasons an engine starts losing RPM or running rough. Our Laser 70 bearings give you an affordable replacement for pricey OEM sets, with no drop in performance. They’re a great fit for sport and scale flyers alike, whether your engine sees regular use or just needs refreshing after years on the shelf.

We know what a four-stroke engine goes through on every flight, so each set is built to stand up to heat, vibration, and high RPM. Precise tolerances mean less wear, less noise, and a crankshaft that spins freely the way it should.

When Should You Replace Laser 70 Bearings?

It’s time to think about new bearings if your engine shows any of these signs:

• Roughness or clicking when turning the prop over by hand
• More noise or vibration than usual during a run
• Difficulty tuning the engine or holding a reliable idle
• Noticeable play when you move the crankshaft side to side
• Stiffness after a long period in storage

Replacing worn bearings early is cheaper and simpler than repairing a damaged crankshaft later.

How Do I Install Laser 70 Bearings?

Replacing engine bearings is a straightforward job once you’ve seen it done. Our short video takes you through each step so you can do it with confidence: Watch: How to Change Your Engine Bearings. A clean, well-lit workspace and a little patience are all it takes to get your engine back together and running.

Keeping Your Laser 70 Running Smoothly

To get the longest life from your new Laser 70 bearings, finish each flying day by running the tank dry and adding a few drops of after-run oil. This helps prevent corrosion while the engine sits between sessions. Store the model in a dry spot, and keep the intake covered or clean so debris stays out.

Laser 70 Bearings FAQ

Do I need special tools to change the bearings?
Not usually. Basic hand tools and careful handling will get the job done, and our video shows you exactly what to do.

Will new bearings improve my engine’s performance?
If your current bearings are worn, yes. Fresh bearings reduce friction and play, which helps restore smooth running, a steady idle, and full RPM.
