Initial Thoughts & Helpful Tips
•Thank you for purchasing this quality Hobbymate product
•Please read and understand all instructions, including the Appendix, before starting
assembly
•Avoid static discharges as they can damage electronic boards
•Don’t trim wires over drone circuitry, small bits of wire can short out and damage
electronics
•Use good quality solder and flux
•Adjust soldering iron to lower temperature when soldering to boards as too much heat can
loosen or damage board components
•Ground pads typically require slightly higher heat setting as they are large and dissipate heat
•Pre-tin wires that will soldered to board pads, use minimal stripped wires to avoid potential
shorts
•Use thread lock on motor and frame bolts
•Before powering drone with battery for first time or after modifying wiring, check for shorts
with a digital voltmeter and use a Smoke Stopper or similar device
•ALWAYS remove props when configuring drone or testing motors with battery connected
•Technical support is available via email [e-mail]
