Power Connections Inspection

Typhoon H/H Pro Battery Connection & Charging adapter Typhoon H+/H520 Battery Connection & Charging adapter
The middle ROUND dots are the balance charging connections. The 2 outer large flat terminals are the positive (vertical one) and
Negative (horizontal one) terminals and used to power the aircraft. The inner horizontal flat terminal is used with the balancing connections.
The alignment grooves (circled in red) on the front sides of the battery are used when it is placed in the
charger and in the aircraft to properly align the battery to the connections.
The H+/H520 battery is the same – except the balance charging connections are flat and not round, the battery
also charges to a higher voltage than the H/H Pro.

Inspect these connections for pitting, discoloration (could indicate bad contact and is overheating) clean with a NON-metallic brush and
contact cleaner. Also, verify the alignment guides are not damaged or overly worn – which may cause mis-alignment.
OF course, inspect & clean you charger.

Propeller Inspection

Check that the Quick Disconnect hold down lugs are not damaged/chipped and the center Button POPs-UP – indicating the spring is in good
condition and you can see the Buttons lugs are undamaged when it pops-up. Verify screws are secure.
Inspect the Props for damage of any kind - chips, discoloration (indicating they may be weak from being bent) etc. Check that their locking lugs are
not missing, chipped or deformed in someway, verify the props look symmetrical and are not un-balanced.
