Dialing In Your Carburetor: The Key to Power Your Zenoah engine demands precision. The carburetor is where that precision meets raw power. Don’t just bolt it on and rip. Take the time to dial it in. This isn’t about guesswork. It’s about understanding how your engine breathes. Every adjustment matters. Setting the Low Speed Needle […]
Sycamore Is the Place to Be This April The off-season is officially over. If you have been sitting on the bench staring at your hull, it is time to load up the trailer. The Atlanta Model Boaters are hosting the 2026 IMPBA Atlanta Spring Nationals on April 18-19. The event is going down at SOWEGA […]
Your Prop Is Not Just a Fan Most guys treat the propeller as an afterthought. They bolt on whatever came in the box and wonder why their Zenoah-powered boat feels lazy out of the hole or falls flat at the top end. The propeller is the only part of your boat that converts engine torque […]
The Free Power Most Guys Leave Behind If you’re running a Zenoah engine with a stock exhaust, you’re leaving rpm on the table. A properly tuned pipe is one of the most impactful performance upgrades you can bolt on to a gas-powered RC boat — and it doesn’t require touching the carb, swapping props, or […]
April Means One Thing The water is warming up. Club schedules are posted. District race dates are locked in. If you have been spending the winter tuning on the bench, now is when it pays off. The 2026 NAMBA district racing season is underway across the country, and the first events of the year are […]
The Carb Is Not Set and Forget Most guys bolt on a Walbro, run the stock needle settings, and wonder why their Zenoah feels soft at the top end. The carburetor is where fuel and air mix. Get that ratio wrong and you’re either running rich and fat, leaving RPM behind, or leaning out at […]
Heat Is the Enemy — Don’t Let It Win Gas RC boats run hot. That’s not a bug — it’s physics. A Zenoah pulling full throttle on a warm summer afternoon generates serious heat, and if your water-cooling system isn’t dialed in, you’ll be limping back to the dock with a seized engine before the […]
Why Break-In Isn’t Optional A new Zenoah engine is a precision piece of machinery. The rings, cylinder bore, bearings, and wrist pin all need time to seat properly before you start pushing the throttle. Skip or rush the break-in process and you’re trading future performance for impatience today. The good news is it’s not complicated […]
The Clock Is Ticking at the Pond You’ve hauled your rig to the field. Other guys are already making passes. The last thing you want is to miss your heat because you skipped something basic in the pits. Race day prep isn’t glamorous work, but it’s what separates a solid run from a DNF. Here’s […]
The Prop Is Your Final Drive Ratio You can tune a perfect carb, nail your break-in, and fit a matched tuned pipe — then throw it all away with the wrong prop. The propeller is the last mechanical link between your engine and the water. It determines your top speed, your acceleration, and whether you’re […]
