The #1 question after you buy a new 1/5 RC car or motor is how to break in and tune the engine for performance. Dan Silagy from O'Neill Brothers Racing walks you through the process of how to correctly break in and tune an engine to avoid damaging or seizing it.Read More
Questions on oil have been popping up quite a bit lately. When you're spending good money on a tuned engine don't skimp on the oil. A $2 bottle of chainsaw oil isn't going to cut it. Sure, chainsaws run WOT for long periods of time but at a much lower rpm. Most of the high end oils out there are good but I wanted to share our experience with Klotz. For some reason it tends to leave a ton of carbon build up. In extreme cases I've seen engine failures. A tuned engine from us for the most part has a .020-.025" squish (piston to combustion chamber) clearance. It doesn't take a whole lot of build up for the carbon to tag the combustion chamber. If this is to happen the carbon can break free from the piston and go into the engine like shrapnel. It's worth every penny to buy a good two cycle oil for your engine. I've posted two pictures below of an engine ran with Klotz and a second with Castor 927. Both engines roughly had about the same amount of run time.
For many engine upgrades and rebuilds, including a Long Block or 2-Bolt upgrade, flywheel and clutch removal is a critical step.
In our second tech video, Dan Silagy from OBR walks you through the entire disassembly. Some important tips included in the video:
- Dan shows you a few "at-home" tricks to perform the removal without expensive tools.
- Differences between CY and Zenoah parts.
Want a cost-effective way to double the power of your engine? The cheapest way is to purchase an OBR Long Block upgrade, and assemble it yourself. But once you receive your Long Block, where do you start?
In our very first tech video, Dan Silagy from OBR demonstrates how to complete a long block with parts from your stock engine. Some important tips included in the video:
- How to install the parts in the right order to avoid having to reassemble the engine.
- Torque specs on the bolts to avoid damaging your new engine.
- Which parts you'll need to focus on to get the upgrade right the first time.
