5. Assembly Instructions
Assembling the S38 Savage Bobber KIT requires patience, precision, and basic modeling tools. This section provides general guidance; refer to the detailed assembly manual included with your kit for step-by-step instructions and diagrams.
5.1. Required Tools and Materials (Not Included)
- Hobby knife or razor blade
- Sanding block and various grits of sandpaper
- Wood glue (e.g., CA glue, epoxy, or aliphatic resin)
- Clamps or rubber bands for holding parts
- Covering film and heat iron/gun (for finishing)
- Small pliers, screwdrivers
- Soldering iron and solder (for electronics)
5.2. General Assembly Steps
- Unpack and Inspect: Carefully unpack all components and inspect for any damage or missing parts. Familiarize yourself with the parts and the assembly manual.
- Wing Assembly: Begin by assembling the wing sections. This typically involves gluing ribs to spars, ensuring proper dihedral and alignment.
- Fuselage Assembly: Construct the fuselage frame, ensuring it is straight and true. Install internal components like servo mounts and battery trays as you build.
- Tail Section Assembly: Assemble the horizontal and vertical stabilizers (elevator and rudder).
- Joining Sections: Once major sections are complete, join the wings to the fuselage and attach the tail section.
- Landing Gear Installation: Install the main landing gear and tail wheel assembly.
- Electronics Installation: Mount the motor, ESC, servos, and receiver according to the manual. Ensure all control surfaces move freely and correctly.
- Control Linkages: Connect pushrods and control horns to the servos and control surfaces (ailerons, elevator, rudder). Adjust for proper throw.
- Covering: Apply the covering film to the airframe using a heat iron or heat gun. This protects the wood and provides the final aesthetic.
- Final Checks: Perform a thorough final inspection, checking all glue joints, screw connections, and electronic wiring. Balance the aircraft to the recommended Center of Gravity (CG).

6. Operating Guidelines
Once your S38 Savage Bobber is fully assembled and all electronics are installed and tested, you are ready for flight. Always ensure you have a clear understanding of RC flight principles and practice on a simulator if you are new to the hobby.
6.1. Pre-Flight Checklist
- Battery Charged: Ensure both the flight battery and transmitter battery are fully charged.
- Control Surfaces: Verify that all control surfaces (ailerons, elevator, rudder) move freely and in the correct direction relative to your transmitter inputs.
- Propeller Secure: Check that the propeller is securely attached and free from damage.
- Motor Test: Briefly test the motor to ensure it spins smoothly and the ESC is functioning correctly.
- Center of Gravity (CG): Confirm the aircraft's CG is within the recommended range. An incorrect CG can make the plane unstable.
- Radio Range Check: Perform a radio range check to ensure reliable communication between your transmitter and receiver.
- Field Clear: Ensure your chosen flying area is clear of obstacles and people.
6.2. Basic Flight Controls
- Throttle: Controls motor speed and thrust.
- Ailerons: Controls roll (tilting wings left/right).
- Elevator: Controls pitch (nose up/down).
- Rudder: Controls yaw (nose left/right).
6.3. Flying Environment
Choose a large, open field or designated RC flying site. Avoid flying near trees, buildings, power lines, or water bodies. Always be aware of wind conditions; light winds are ideal for initial flights. For optimal performance and safety, ensure good visibility of your aircraft at all times.
7. Maintenance
Regular maintenance will ensure the longevity and safe operation of your S38 Savage Bobber.
- Post-Flight Inspection: After each flight, inspect the airframe for any damage, loose connections, or signs of wear. Check propeller for nicks or cracks.
- Cleaning: Keep the aircraft clean. Wipe down surfaces to remove dirt, dust, or oil.
- Control Linkages: Periodically check all control linkages for slop or binding. Ensure screws and nuts are tight.
- Motor and ESC: Check motor bearings for smoothness and ensure the ESC is free from debris and overheating.
- Battery Care: Follow proper LiPo battery charging, discharging, and storage procedures. Never leave batteries unattended while charging.
- Storage: Store the aircraft in a cool, dry place, away from direct sunlight and extreme temperatures. Protect it from physical damage.
8. Troubleshooting
This section addresses common issues you might encounter and provides potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Aircraft does not respond to controls | Low battery (transmitter or receiver), binding issue, faulty receiver/servo | Charge batteries, re-bind transmitter/receiver, check wiring, replace faulty components. |
| Motor not spinning | Disconnected motor/ESC wires, faulty ESC, low flight battery, motor jammed | Check connections, ensure battery is charged, inspect motor for obstructions, test/replace ESC. |
| Aircraft flies erratically/unstable | Incorrect Center of Gravity (CG), control surfaces not trimmed, damaged airframe, strong wind | Adjust CG, trim controls on transmitter, inspect for damage, wait for calmer weather. |
| Short flight time | Battery not fully charged, old/damaged battery, inefficient propeller, excessive throttle usage | Ensure full charge, replace old battery, check propeller size/pitch, manage throttle. |
| Excessive vibration | Unbalanced propeller, bent motor shaft, loose motor mount | Balance propeller, check/replace motor shaft, tighten motor mount screws. |
