RE: Eletronic engine syncronizer **SUPPORT **
Email me your phone number. I have never had a report like this before. I am very interested in getting to the bottom of this one since this is a key feature of the product and never had an issue.
Are you getting two yellow leds while synchronizing? If not then you may be below the sync point and you may need to reprogram the sync point. There are some customized units out there with this feature disabled. I know who has them though. You did buy it new from RC Showcase didn't you?
