How to Find and Balance the Center of Gravity on RC Planes Every pilot remembers their first major crash. For many of us, it happened seconds after hand launching a brand new model. You throttle up, toss the plane into the air, and watch in horror as the nose pitches up violently. The aircraft climbs straight toward the clouds, stalls, rolls over, and slams nose first into the dirt. You check t...

2 Blade vs. 3 Blade vs. 4 Blade RC Propellers: Performance Guide When you look at a full scale World War II fighter plane sitting on the tarmac, one of the first details that grabs your eye is the propeller. The massive blades clawing the air look powerful and correct. It is no surprise that when we fly our remote controlled warbirds, we want that same aggressive look. Beginners and veteran pil...

How to Choose the Right LiPo Battery for Your RC Plane. Learn how capacity and weight affect the Center of Gravity (CG), decode C-ratings to calculate motor amp draw, select correct voltage (S-ratings), and follow charging safety guidelines.

Learn how to stop your RC plane ESC from continuously beeping. This guide covers throttle range calibration, receiver signal issues, and transmitter trim quick fixes.

RC Plane Pre Flight Checklist: Avoid Maiden Flight Crashes Every remote control pilot remembers the absolute thrill of their first maiden flight. You spent hours selecting the perfect model, unboxing it, charging the battery, and heading out to your local flying field. Your heart is racing as you throttle up, toss the plane into the air—and then, in a split second, watch in horror as the plane...

Every remote control boat enthusiast knows the feeling: you charge your battery to full, grease the flex shaft, place the boat in the water, and pull the transmitter trigger all the way back. Instead of screaming across the lake in a smooth, flat line, the bow starts hopping up and down, slapping the surface...

RC Boat Water Cooling Setup & Troubleshooting EXHOBBY If you run a brushless RC boat, heat is your main enemy. Brushless motors and Electronic Speed Controllers (ESCs) draw huge current from LiPo batteries, and without an easy way to shed that heat, your electronics will cook. That leads to thermal shutdown, melted solder joints, or outright fried components. Air cooling works fine for cars and...

LiPo Batteries for RC Boats: Safety & Selection. Learn how water friction demands higher C-ratings, how to select S-ratings and capacity, prevent puffed packs, waterproof balance leads with simple hacks, and follow safe charging practices.

Mono vs. Catamaran vs. Hydroplane: RC Boat Hull Guide Every remote control boat runner eventually faces the same choice when upgrading or expanding their fleet: what hull shape should I buy next? You can install a powerful brushless motor and the highest C rating LiPo battery pack, but if your hull design does not match your water conditions, you will end up either capsizing, spinning out, or r...

How to Retrieve a Stuck or Flipped RC Boat Safely. Every RC boat captain knows that sudden, sinking feeling when a boat stops dead in the middle of the lake. It happens to everyone eventually. You flip a speedboat upside down after a sharp turn, snag a sailboat in a patch of thick weeds, or simply run the LiPo battery down fifty yards from shore. When a boat gets stranded, your first instinct is to get it back as fast as possible. But acting on impulse usually leads to lost gear or worse. The difference between a successful recovery and a lakeside disaster comes down to preparation...

RC Boat Propeller Guide: Tuning for Max Speed Every RC boat hobbyist eventually hits a wall where pulling the throttle trigger all the way back doesn't give you any more speed. You've bought a higher C rating LiPo battery, greased the flex shaft, and adjusted the trim tabs, but the GPS speed reader won't budge. The blocker is usually the propeller. In high speed boating, the prop acts like your...
