Frequently asked questions (FAQ)

Q: How to handle TracLog? Is it very sensitive to impact?

A: TracLog is very smart and sensitive device yet very robust. Anyhow always use some spacer in front of TracLog to avoid direct contact with pulley. Helper at pulley with gloves is recommended, but be very carefull; 40grams TracLog can be dangerous bullet if operator at winch switch is feebleminded. I fly TracLog for years alone at training site and usually don’t wind up TracLog to pulley…

Always check TracLog for any cracks on heat shrink tubing and replace tube immediately when necessary. Always use double layer tubing! Don’t use TracLog in wet conditions, it is NOT waterproof.

Q: How to fix TracLog on line?

A: The best way looking from F3X machine hook. Hook-Parachute-about 1m line-TracLog and rest of x100m of line…

Q: I forgot to switch-off TracLog. Battery is dead. What now?

A: Hmmm, you are lemon (same as me). There is small one cell LiPo in TracLog. Connect TracLog to 4.0V source for while (30sec) and pray. Try to connect again to your LiPo charger (use max 4,2V and about charging 170mA current) if it will start charging. If not, contact me.
