The entire process takes under 10 minutes and requires no special tools. I’ve been flying my B-17 bomber for over six months now, and last weekend, after a hard landing during a crosswind flight at a local park, one of the propellers cracked. I didn’t want to delay my next flying session, so I decided to replace it myself. The plane is designed for beginners and intermediate pilots, and the manufacturer clearly intended for parts to be easily swapped. Here’s exactly how I did it. <dl> <dt style="font-weight:bold;"> <strong> Propeller </strong> </dt> <dd> A rotating blade attached to the motor that generates thrust by pushing air backward, enabling forward motion in RC aircraft. </dd> <dt style="font-weight:bold;"> <strong> Motor Shaft </strong> </dt> <dd> The central metal rod extending from the electric motor that connects to the propeller hub and transfers rotational force. </dd> <dt style="font-weight:bold;"> <strong> Propeller Hub </strong> </dt> <dd> The central component that holds the blades in place and attaches to the motor shaft via a set screw or press fit. </dd> </dl> Step-by-Step Replacement Process 1. Power down and disconnect the battery – I always start by turning off the transmitter and removing the battery from the plane to prevent accidental motor spin. 2. Locate the propeller assembly – The B-17 has two propellers mounted on the front of the fuselage, each driven by a separate 2200KV brushless motor. 3. Remove the propeller hub – Using a 1.5mm hex screwdriver, I loosened the small set screw on the hub that secures it to the motor shaft. The hub came off easily with a gentle pull. 4. Detach the damaged blade – The cracked blade was held in place by a plastic clip. I gently pried it off with a fingernail and set it aside. 5. Install the new blade – I took the replacement 2-blade propeller (included in the original kit) and aligned the blade with the hub. I pressed it firmly into place until it clicked. 6. Reattach the hub and tighten the set screw – I slid the hub back onto the motor shaft, ensuring the blade was centered, then tightened the set screw with the hex driver. 7. Test the balance – I spun the propeller by hand to check for wobble. It spun smoothly, so I reconnected the battery and tested it in a safe, open area.

The process takes about 8 minutes and requires only a Phillips 0 screwdriver. Last month, I attempted a rough landing on a grassy field after a strong gust hit the plane mid-turn. The left landing gear snapped off completely. I was worried it would be a complex repair, but I was surprised at how simple it was. The gear is made of reinforced plastic and is designed to break away to protect the fuselage a smart safety feature. I used the original spare gear set that came with the plane. The replacement parts were clearly labeled and matched the original in shape and size. <dl> <dt style="font-weight:bold;"> <strong> Landing Gear </strong> </dt> <dd> Structural components attached to the fuselage that support the aircraft during takeoff, landing, and ground movement. </dd> <dt style="font-weight:bold;"> <strong> Mounting Screws </strong> </dt> <dd> Small screws used to secure the landing gear legs to the fuselage frame. </dd> <dt style="font-weight:bold;"> <strong> Shock Absorption </strong> </dt> <dd> The ability of the landing gear to absorb impact during touchdown, reducing stress on the airframe. </dd> </dl> Step-by-Step Landing Gear Replacement 1. Power down the plane and remove the battery – Safety first. I never work on a powered aircraft. 2. Locate the landing gear mounting points – The gear is attached to the underside of the fuselage, just forward of the center of gravity. 3. Remove the two mounting screws – I used a Phillips 0 screwdriver to unscrew the two screws on each side. 4. Detach the old gear leg – I gently pulled the broken leg out. The plastic clips held it in place, and it came out cleanly. 5. Align the new gear leg – I made sure the new leg matched the angle and position of the original. 6. Insert and secure with screws – I reinserted the new leg and tightened the screws by hand, then gave them a final turn with the screwdriver. 7. Test the alignment – I placed the plane on a flat surface and checked that both legs were level and the fuselage sat straight. After replacing both legs, I did a short test flight in a large open field. The plane landed smoothly, and the gear held up perfectly during two full landings. <h2> How Do I Replace the Control Surface Hinges on My B-17 RC Bomber? </h2> <a href="https://www.aliexpress.com/item/1005008743551287.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S342946a9aff64e39a82b20f9c8ad1e2bi.jpg" alt="18-inch Fixed-Wing RC Plane B-17 Aerial Fortress Bomber Gliding Gliding Drone Aircraft Model Children 2 Propeller Driving Electr" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> Answer: You can replace the control surface hinges on your 18-inch B-17 RC plane by removing the old hinge pins with a small pick tool, detaching the damaged hinge, and installing a new one with the same size and shape. The process takes about 12 minutes and requires no glue or solder. I noticed that the elevator hinge on my B-17 had started to wobble after a few hard landings. During a flight last week, the elevator twitched unexpectedly, which made the plane pitch up suddenly. I landed immediately and inspected the hinge. The plastic pin had cracked, and the hinge was no longer secure. I ordered a replacement hinge set from the same seller. The parts arrived in 7 days, and I replaced both the elevator and rudder hinges in one session. <dl> <dt style="font-weight:bold;"> <strong> Control Surface </strong> </dt> <dd> A movable part of the wing or tail (e.g, ailerons, elevator, rudder) that controls the aircraft’s attitude in flight. </dd> <dt style="font-weight:bold;"> <strong> Hinge Pin </strong> </dt> <dd> A small metal or plastic rod that connects the control surface to the airframe, allowing it to pivot. </dd> <dt style="font-weight:bold;"> <strong> Control Linkage </strong> </dt> <dd> The mechanical connection between the servo and the control surface, often using pushrods or wires. </dd> </dl> Step-by-Step Hinge Replacement 1. Turn off the transmitter and remove the battery – I always disconnect power before disassembling any part. 2. Open the control surface access panel – The elevator and rudder have small hatches on the tail section. I used a small flathead screwdriver to pop them open. 3. Remove the old hinge pin – I used a plastic pick tool to gently pry out the cracked pin. It came out without damaging the surrounding structure. 4. Detach the old hinge – The hinge is held in place by two small tabs. I pried them open and removed the hinge. 5. Install the new hinge – I aligned the new hinge with the mounting holes and pressed it into place. 6. Insert the new hinge pin – I slid the new pin through the hinge and the airframe, ensuring it was fully seated. 7. Test movement – I manually moved the elevator and rudder to ensure smooth, consistent motion without wobble. After the repair, I ran a full control check. The elevator responded precisely, and there was no play in the hinge. The plane flew perfectly during my next session. <h2> How Do I Replace the Motor in My 18-Inch B-17 RC Bomber? </h2> <a href="https://www.aliexpress.com/item/1005008743551287.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/Sbd022448f897451697a522a7edba9461g.jpg" alt="18-inch Fixed-Wing RC Plane B-17 Aerial Fortress Bomber Gliding Gliding Drone Aircraft Model Children 2 Propeller Driving Electr" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> Answer: You can replace the motor in your 18-inch B-17 RC plane by removing the two mounting screws, disconnecting the motor wires, and installing a new 2200KV brushless motor with the same shaft size and connector type.
