Winter LiPo Battery Storage Guide for RC Airplane Pilots

By York R/C Club

Introduction

Colder air means longer throttle-on times and stressed batteries. As a result, pilots need to adjust how they store packs for the season. However, a LiPo kept at the wrong voltage or temperature will puff, self-discharge, or lose punch by spring. Therefore, use this guide for the exact voltage, temperature, and routine that keep packs healthy all winter.

TL;DR — Balance-charge to 3.80 V/cell, store packs between 45 °F and 70 °F, check voltage monthly, and log internal resistance. In short, that’s 90% of winter LiPo care.

LiPo Batteries in RC: Power, Safety, and Care

By York Area R/C Club

LiPo (Lithium Polymer) batteries have revolutionized the RC hobby, offering lightweight, high-power solutions for planes, cars, drones, and more. However, they demand responsible handling. Whether you’re new to RC or a seasoned flyer, understanding how to charge, store, and care for your LiPos is essential for performance and safety.In this article, we’ll break down the essentials of LiPo battery usage — from choosing the right pack to avoiding fire hazards — so you can fly confidently and safely.

🔋 What Makes LiPos Different?

LiPo batteries offer a high energy-to-weight ratio, low internal resistance, and fast discharge capability. Compared to NiMH or NiCd, LiPos are lighter, more powerful, and recharge faster.

  • Cell count (S): Determines voltage (e.g., 3S = 11.1V)
  • Capacity (mAh): Affects flight time (higher = longer)
  • C rating: Indicates how fast the battery can safely discharge

Therefore, selecting the right combination of voltage and capacity ensures your RC setup gets both endurance and performance.

⚡ Charging LiPo Batteries Safely

  • Always use a balance charger set to LiPo mode.
  • Charge in a fireproof bag or container (e.g., LiPo safe).
  • Never leave charging batteries unattended.
  • Charge at 1C rate unless the pack is rated for faster charging.

In addition, inspect connectors and wires before charging. Frayed or loose wires can spark fires or damage your charger.

🔥 Storage and Transport Tips

Improper storage is one of the leading causes of LiPo damage. To extend lifespan and reduce risk:

  • Store at 3.8V per cell (storage voltage) — most chargers have this option.
  • Keep in a cool, dry location — ideally in a fireproof case.
  • Never store fully charged or completely discharged batteries for long periods.
  • Use a battery checker to monitor voltage regularly.

🛠 How to Spot a Damaged LiPo

LiPo batteries don’t last forever. Watch for these signs that a pack needs to be retired:

  • Puffy or swollen cells
  • Cracked or torn outer wrapping
  • Noticeable drop in performance or flight time
  • Unusual heat during use or charging

If in doubt, don’t risk it. Dispose of damaged LiPos safely through a local hobby shop or battery recycling center.

🧯 What To Do in Case of Fire

Although rare, LiPo fires are extremely intense. Prepare ahead of time by keeping:

  • A Class D or dry sand fire extinguisher nearby
  • Non-flammable charging surface (e.g., ceramic tile or concrete)
  • Your charging area in a ventilated space away from flammable items

Never use water on a LiPo fire. It can intensify the chemical reaction.

Keeping Your RC Airplane in Trim: A Practical Guide to Balancing

A well-trimmed RC airplane doesn’t just fly better — it flies safer, more predictably, and with less pilot fatigue. Whether you’re fine-tuning after a maiden flight or correcting a nagging pull to one side, proper trimming and balancing are essential for smooth and efficient flying. This guide walks you through practical methods to get your aircraft flying hands-off straight and level.

⚖️ 1. Start With Proper CG Balance

Why it matters:
The center of gravity (CG) affects pitch stability. If it’s too far forward or back, your plane will either nose-dive or behave erratically.

Steps:

  • Refer to your plane’s manual for the recommended CG location.
  • Place fingers (or use a CG balancer) at the specified point on the wing.
  • Add or remove weight (typically in the nose or tail) to balance its level.

Tip: Use stick-on lead weights or shift internal components to make fine adjustments.

✈️ 2. Perform the Hands-Off Glide Test

Why it helps:
A short glide test can reveal CG or trim issues early, even before the motor is running.

Steps:

  • At shoulder height, gently toss the plane into the wind with no throttle.
  • If it dives sharply → CG is too far forward.
  • If it stalls or flares upward → CG is too far aft.
  • If it glides smoothly in a straight line → You’re good!

🎮 3. Use In-Flight Trim to Fine-Tune

Once airborne and trimmed for level throttle, fly straight and level. Let go of the sticks briefly and observe:

  • Plane climbs or dives? → Adjust elevator trim.
  • Drifting left or right? → Adjust aileron trim.
  • Nose yaws during level flight? → Adjust rudder trim.

Make small adjustments, one click at a time, using your transmitter trim tabs.

🛠️ 4. Mechanically Center Before Electronically Trimming

Why?
If you have to apply lots of electronic trim, something’s likely off mechanically.

Fix it:

  • Remove the servo arm and reattach it closer to the center position.
  • Adjust clevis or pushrod length as needed.
  • Re-test flight trim.

Keeping mechanical trim close to neutral helps maximize servo travel and resolution.

🌬️ 5. Trim in Calm Conditions

Best practice:
Trim flights early in the morning or on calm evenings. Less turbulence = more reliable observations.

📏 6. Balance Laterally Too

Not all balance is front-to-back — side-to-side (lateral) balance matters too.

Check it:

  • Suspend the plane from its propeller shaft and rudder/tail.
  • If one wing consistently dips, add a small counterweight (like a coin) to the opposite wingtip.

🛩 7. Save Trim Settings by Model

If your transmitter allows it, save your trim and sub-trim settings per model memory. That way, you won’t have to retrim every time you switch planes.

🧭 Final Thoughts

A trimmed and balanced aircraft is a joy to fly — predictable, efficient, and smooth through the air. By consistently checking CG, performing glide tests, and fine-tuning your trim during calm conditions, you’ll set yourself up for successful, stress-free flights every time.

Take the time to get it right, and your RC plane will thank you with rock-solid performance.

How to Tune Your RC Nitro Engine for Peak Performance

Tuning a Nitro Engine: A Complete Guide

By York Area R/C Club

Tuning a nitro engine might seem intimidating, but it’s one of the most rewarding skills an RC pilot can master. Whether you’re chasing speed, smooth idle, or reliability on race day, proper tuning ensures your engine runs at its best under changing conditions. This guide walks you through the essentials for both beginners and seasoned flyers.

🔧 Understanding the Basics: High vs Low Speed Needles

Most RC nitro engines have two primary adjustment points:

  • High-Speed Needle (HSN): Controls fuel flow at full throttle.
  • Low-Speed Needle (LSN): Controls fuel flow at idle and low RPMs.

Additionally, the idle screw sets the minimum throttle opening to keep the engine running when you release the trigger.

⛅ Adjusting for Weather and Conditions

Nitro engines are sensitive to air density, which changes with temperature, humidity, and elevation. Here are general rules:

  • Hotter weather: Lean the HSN slightly.
  • Cooler weather: Richen the HSN (add fuel) to compensate.
  • High humidity or elevation: Engines tend to run rich; you may need to lean both needles.

Always make changes in small increments (about 1/8 turn at a time), and let the engine warm up first before making adjustments.

🚗 Signs of Improper Tuning

Knowing how the engine behaves will help you avoid damage:

  • Too rich: Excessive smoke, sluggish throttle, oily residue.
  • Too lean: High-pitched sound, engine runs hot, low smoke, risk of engine damage.
  • Low idle or stalling: LSN may be too rich or idle screw set too low.

Also watch the smoke trail and use a thermometer if possible. Ideal operating range is around 210–230°F (approx. 99–110°C), though it depends on your engine.

⚖️ Step-by-Step Tuning Process

  1. Start Rich: Begin with settings richer than you think necessary to avoid damage.
  2. Set Idle: Adjust the idle screw so the engine runs steadily without stalling.
  3. Tune LSN: Use the “pinch test” (momentarily pinch the fuel line) to check low-speed behavior. The engine should rev a bit and then die after 2–3 seconds.
  4. Tune HSN: Perform full throttle passes. Lean the HSN until top speed increases, then back off slightly for safety and engine longevity.
  5. Fine-Tune: After setting HSN, recheck idle and low-speed settings—sometimes changes in full throttle behavior affect idle/low end.

🚨 Quick Tips for Field Tuning

  • Use the pinch test for LSN accuracy.
  • Don’t excessively lean just for speed—it can damage the engine.
  • Bring a temperature gun or thermometer to monitor heat.
  • Mark your needle positions once you’ve found good settings—helps when conditions change.
  • Clean the air filter often—dirty filters reduce airflow and can affect tuning dramatically.

🚀 In Closing

With careful observation and modest adjustments, you can turn a temperamental nitro engine into a reliable powerhouse. Every engine has its quirks, so consistent technique, patience, and tuning in response to conditions will give you the upper hand. Head to the field, grab your tuning tools, and let your nitro sing!

Troubleshooting RC Servo Problems: Buzzing, Glitches & Failures

By York Area R/C ClubServos are the muscle behind your RC aircraft’s control surfaces. When they malfunction, they can turn a perfect flight into a real headache. Fortunately, most servo problems are preventable or fixable. Let’s break down the causes and cures for common servo issues so you can get back in the air with confidence.

🔊 Buzzing Servos

It’s not uncommon to hear a faint buzz from your servos, especially under load. However, constant or loud buzzing often signals trouble.

  • Cause: Mechanical binding in the control surface linkage.
  • Fix: Inspect linkages for friction or misalignment. Ensure clevises are not too tight and that control horns are moving freely.
  • Tip: Try disconnecting the pushrod. If the buzzing stops, the issue is likely mechanical, not electrical.

⚡ Jittering or Glitching

Sudden twitches or random movements when the sticks are untouched usually indicate interference or voltage issues.

  • Cause: Weak receiver signal, bad wiring, or power spikes.
  • Fix: Use a glitch-buster capacitor. Check for loose servo plugs or chafed wires. Rebind your receiver if the signal seems weak.
  • Upgrade Tip: Switch to a 2.4GHz radio system if you’re still using older FM gear — it’s more immune to interference.

🐢 Slow or Weak Response

Sluggish servos can be frustrating and dangerous, especially in windy conditions.

  • Cause: Low battery voltage or worn servo gears/motor.
  • Fix: Charge your receiver battery or upgrade to a BEC if using electric power. If only one servo is slow, consider replacing it.
  • Tip: Listen for a high-pitched whine or check for heat — it may indicate a failing motor inside the servo.

🚫 Complete Servo Failure

When a servo stops responding entirely, it’s time for a serious inspection.

  • Cause: Burned-out motor, fried circuit board, or broken internal gear.
  • Fix: Try swapping in a known-good servo in the same port. If that works, the original servo is likely dead and should be replaced.
  • Tip: Some servos have replaceable gears or motors — but at hobby pricing, it’s often quicker to just swap it out.

🧰 Preventive Maintenance Tips

  • Secure all wiring with zip ties or tape to avoid in-flight vibration wear.
  • Check servo arms for cracks and replace plastic ones with heavy-duty versions for larger planes.
  • Use servo testers to check for erratic behavior before installation.
  • Avoid extreme throws unless your servo torque rating supports it.

🌐 Helpful Resources

🎯 In Closing

Servos may be small, but they play a critical role in every flight. By understanding how to recognize and address buzzing, glitching, or failure, you’ll fly safer and with greater confidence. Keep them clean, powered, and stress-free — and they’ll keep your control surfaces sharp and reliable.

How to Set Up RC Airplane Servos

By York Area R/C Club

Setting up servos correctly is essential for precise control, smooth flight, and mechanical reliability in both RC planes and helicopters. Whether you’re flying a 4-channel trainer or a collective-pitch heli, proper servo alignment and configuration makes all the difference. In this guide, we’ll walk you through how to set up servos step‑by‑step—from centering and mounting to fine‑tuning and testing—so your aircraft responds exactly the way it should.

🛩 RC Plane Servo Setup

1. Choose the Right Servo for Each Surface

  • Standard servos are great for trainers and sport models.
  • Metal‑gear servos offer higher torque—ideal for rudder or tailwheel control.
  • Mini/micro servos are suited to smaller aircraft or park flyers.

As a result, selecting the correct servo type ensures both durability and effective performance.

2. Center the Servo Before Installation

Use a servo tester or plug the servo into your receiver. Then, power on your transmitter with trims centered. This ensures the servo begins in its neutral position.

3. Mount Securely and Align Linkages

  • Use vibration‑isolating grommets and appropriate screws.
  • Keep pushrods straight and parallel when possible.
  • Ensure servo arms are perpendicular at the neutral stick position.

Therefore, accurate mounting reduces stress and promotes smooth surface movement.

4. Adjust Travel and Sub‑Trim

Use your radio’s sub‑trim to fine‑tune the neutral. Additionally, correctly set travel limits to prevent overdriving—reducing the risk of servo burnout or linkage binding.

5. Perform a Full Range Test

  • Move sticks through full deflection and check for binding.
  • Verify the control surfaces return to center smoothly and consistently.
  • Finally, conduct a proper range check before your maiden flight.

🚁 Helicopter Servo Setup

1. Know Your Layout (CCPM or Mechanical Mix)

Most modern helis use CCPM (Cyclic Collective Pitch Mixing), where multiple servos work in tandem for cyclic and pitch control. Consequently, setup precision is essential.

2. Level the Swashplate at Mid‑Stick

Center your throttle/pitch stick. Next, use a swash leveler to ensure the swashplate is level front‑to‑back and side‑to‑side. Accurate leveling avoids uneven control response.

3. Match Servo Arm Angles

  • Servo horns should be 90° relative to the linkages at mid‑stick.
  • Use sub‑trim for fine adjustments. However, don’t rely solely on endpoint adjustments.

4. Calibrate with a Flybarless Controller

If you’re using an FBL unit (like Spektrum AR7200BX, MicroBeast, or Spirit), then follow the setup wizard carefully to ensure correct servo direction, range, and pitch alignment.

5. Check Collective and Cyclic Movement

  • Verify the swash moves smoothly and evenly without binding.
  • Ensure collective and cyclic changes occur symmetrically.
  • For 3D setups, target approximately +12° to −12° of collective pitch.

In summary, precise calibration ensures balanced and predictable performance.
