Since then I've had a couple conversations with Bendix. Same experience as others have reported: not as helpful.

It took me 7 months! and I would bet 100 emails and phone calls with Zach Williamson at Bendix King and Bruce Grammon at Midcontinint to to get the proper wiring schematics to make a Sorcerer work in my latest 10 last year. Bruce had no idea what a TruTrak was until last June and admitted that Bendix King did not supply MidContinent with Mannuals, etc. even though MidContinent was the authorized repair center for TruTrak. I sent the trim module (which MidContinent lost) and the Head to MidContinent Two times to be checked out only for Bruce to tell me it checked OK on the bench. I finally got Zack at Bendix King to Get off his A-- and look at Installation Manuals IN DETAIL. He said that the schematics sent with the Installation manuals did not show the changes in the newer units and Trim modules. Once he shared that information with me, I now have a working Blue Screen (newer Sorcerer) that works. Like I said, this Saga took only 7 Months and several hundred dollars in shipping and a new Trim Module from EDMO Industries in Washington I would NEVER do business with Bendix King or MidContinent again if I could avoid it.

I have had nothing but good service from Bruce and Mid Continent. Better even than with TruTrak back in the day. Bendix King, on the other hand, I wont even try calling. I feel like I know more than their tech guy does. Probably not the case, but when I first started dealing with them, it probably was the case. I buy from Edmo or Aviall and use Mid Continent for service, so I dont ever even have to deal with BK. On the experimental stuff, however, I cant speak to Mid Continents knowledge. As time goes on, I am sure they will get better and better.

Specifically with a G3X based system? Im curious what the process was like to reconfigure the wiring and remount the servos/linkages. Im not looking forward to replacing mine, but its going to become inevitable at some point. Phil Sent from my iPhone > On Jan 4, 2021, at 8:34 AM, Saint Aviation wrote: > > > Thats interesting.

The servos are cheap at $750 and they mount same as TT. But a system of screen, ADAHRS and wiring is going to cost probably 2-3 times what the servos do, even in a 7" screen size.

The main difference is in the roll servo with the brace that goes up to the upper bell crank bracket. Since the Garmin servo just has a 1/16 or 1/8 plate, where the other servos have a 3/4 or so thick base, the brace would require a spacer to make up the difference. Also, the G3X servos require nuts on all of the bolts for the same reason. The Garmin arm is very similar to the standard arm on the other servos. I dont know if they have long output arms available like are used in the RV-6 roll servos for the other brands. For the RV-10, I dont think they have the torque enhancer, so that would be a little different, but the arm with a pushrod is what they use on the -10. The wiring is more of a difference, as usually the Dynon and TruTrak dont have 2-conductor shielded wire as is needed for the CAN Bus. The Dynon does have twisted pair wires, but they are not shielded. I have used existing TruTrak wiring in the past to install a Dynon auto pilot, but Im pretty sure the Garmin is going to want shielded wire. Also, the Can Bus needs to continue from the servos to something else in line. If you have a GMU 11 in the tail, then you have the CAN bus wiring there, so that shouldnt be hard to access. The roll servo would require cutting into the CAN Bus wiring in the side panel and running that to and from the roll servo. Also, both servos can provide auto trim, but the trim would have to run through the servo. I am not a fan of auto roll trim, but auto pitch trim is great. In that case, you can cut the two pitch trim servo motor power wires near the pitch servo and run both sides of both to the pitch servo and youre good to go.
