Status: offline 		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?

Status: offline 		Yeah, holding either one until it dies. Observing to make sure that the magnet on the dead engine doesn't end up in front of the hall effect sensor too.

Status: offline 		Thanks for the call Bill. I knew it was me that was committing the error, not the Twinsync. I guess I hadn't read carefully enough to know that each of the green lights is supposed to come on as a magnet passes by the corresponding sensor. One of the sensors wasn't picking up the magnet (i.e. no green light), so I flipped it over and presto, it got a reading (green light came on). What I had thought was synchronization before was really just nothing, coincidence that the motors were running relatively near each other. Now it is perfectly synced up and the dead stick feature works fine, I tested it with either engine. Great product, and even better technical support!

Can't wait to get that bird in the air and hear those motors doppler by.

Status: offline 		Yes -- it should work fine on electrics. Most of the development was done inside on the bench with a pair of brushless motors and ESCs. Glow and Gas were tested extensivly but development was done on electrics. However, Do you need this on electrics???? I guess if one fails but otherwise are they not pretty close to being synced?

Status: offline 		Thanks for the reply. It does make sense that a significant amount of the testing would be performed with an electric system because of the convenience. I have two Astroflight brushed marine 25s installed in a Dumas 48 inch PT boat. The motors are counter rotating and each one is run separately by an Astroflight 408D reversible speed control and its own 14 cell nickel cadmium battery pack. They are turning at about 8000RPM according to my calculation. The controls are connected in parallel to the throttle channel. They are not necessarily synched as each motor and controller are slightly different. When they get out of synch, the boat runs tilted to one side and digs in on the same side during a turn. I’ve uploaded a couple of images to show you the installation. From what I have read, the Twinsync should help. Do you see any problem with the counter rotation?

Status: offline 		No problem with counter rotation. RPM limit of the Twinsync is about 23,000. So as long as you stay below that you are fine. Exceed 23,000 and it declares deadstick (idles both). With electrics you can speed up the response time quite a bit for instant sync but you can here a little oscillating.

Status: offline 		Bill,

Help me out....installing a new unit in a Cessna 310 with G26EIs. In hooking things up initially, LED 5 has a green glow that brightens when the sensor is passed by the magnet but the light never goes completely out. LED 6 is not lit at all and goes green only when the sensor passes the magnet and this, I assume, is as it should be. What's causing this with LED 5 and is it a problem? Also, any tips for mounting the sensor to read the ignition magnet on the rear of the G26?

Thanks, Mac Hodges

Status: offline 		You've got enough going on that it is probably best that we speak by phone when you are at the unit. I have a few simple tests I want you to run (see if the problem follows the sensor). I have only had 1 out of 1000 sensors turn out to be bad so far and it was because the cable company reversed the red and black wire in the male connector. So I want to get to the bottom of this problem.

Status: offline 		That is correct. They are sold seperately for $2.50 a pair. email me at billw@nc.rr.com and I can get you some or you can get them from RCShowcase.

Status: offline 		Bill,

Reversed the component and all is well. LED 5 is off and comes on as it should when the sensor passes the magnet. Thanks for taking the time to help me.
