Dennis,
I also looked over the guide and see nothing about a control line setting, however looking at the old Phoenix guide it doesn't mention the control line setting either. When I talked to the tech support at Castle he said the Talon has it the Thunderbird line does not. If it does it is great for smaller say 35 size ships and the price is $58 list and $50.99 at Tower, not bad. Maybe I didn't ask the right question of the tech guy, has someone tried this ESC?
Best, DennisT
