Has anyone else had any problems with the newer model of the TruTrak pitch servo? Mine looks like it was thrown together where the DB9 connector is and the wire grommet is split, the mounting bracket aft hole is off by ¼”, the bolt they sent to attach to the bellcrank is too short, and the entire instructions comprised two fuzzy pictures. Not what I would expect for a $1300 servo. And no, I haven’t talked to them. The last couple of times I emailed or left a VM, no one ever returned my call.

My servo looked fine, but I had the same problem with the mounting adapter. What I figured was that the adapter was made to go with their “new” RV-10 autopilot which also has a yaw damper. The yaw damper adapter goes under the back of the pitch servo adapter plate. I do not have pictures, but all I did was add a spacer under the adapter plate. After that, it worked fine.
In my fuzzy pictures I got, you can see the yaw damper.
Hope this helps.

I received mine a couple of weeks ago but hadn't opened it until your
msg. I just checked and it looks like they (tru Trak) are consistent.
the box that contains the DB9 connector isn't machined/built correctly
and there are gaps where the parts are supposed to mate/match, the
grommit exiting the box for the wires to the motor is also split, I
haven't checked the mount, but after checking these two items, I'll
guess it's the same story, I suspect we got our units from the same
'hurry-up batch'. (as I recall they were several weeks late in shipping)

I have not had your problems. I really did not notice or look for the grommet split either. my holes for the new bracket matched.
I suspect that they are having growing pains.

Got mine in May after a 4 month delay (ordered & paid for it in January). Mounting bracket was slightly different design than your picture shows, and the bolts lined up OK with the battery/bellcrank plate. Servo was nominal without any of the quality control problems your photos show.
Looks like you got one made either Friday afternoon or Monday morning. My experience with them is that they don't answer e-mail, but if you can get a tech on the line they are terrific about making things right.

Mike, mine for the 7 were perfect but shipped a year ago and I just talked to John today. They answered on the third ring. Helpful as usual. Just another data point.

Bill,
Good info. I think the QC problems are because of growing pains as several other vendors are seeing from the boom in homebuilt’s and specifically high end models like the -10. No one should mistake my comments with a dislike of their products, I would still use their AP over anyone else’s
I would have like to have heard something out of TruTrak about my, and others, posts on this subject though. I know Andrew Barker trolls this list and I’m 99.9% sure he probably read it first thing this morning. Hopefully they are just trying to figure out the best way to address it.

Guys & Gals,
I wanted to post some follow-up conversations I had with Andrew this morning. He contacted me once he had some answers. Good stuff that gives me the warm fuzzy’s.

No worries!
My only concern with the split washer is that if they cut too much away, then the servo wires might work their way into the split. This is why we are thinking about changing it. We have not had any problem with chafing, at least not that I have been told about.
Thanks for the bolt length help I will get back with shipping again today and check on that.
You are more than welcome to post my reply to the list.
Once again thanks for the help and I certainly do appreciate the constructive criticism.

Andrew,
Thanks for the reply. As I said in one of my later posts I figured you were looking into things. Don’t worry about shipping out a new mounting bracket as long as you don’t have any alignment concerns. Everything looked pretty good on my install once I drilled a new hole. I didn’t notice the split grommet on the roll servo way back when I did that one but my concern was that the wire could eventually work into the split and chafe. If you haven’t seen this in a few thousand servos, I’m not too concerned. I also put a dab of E6000 on it to make sure it couldn’t wiggle. The length of bolt I got was a -11A and the one that I used was a -13A, although a -12A probably would have also worked.
I’m glad you didn’t see my post as bashing TruTrak. It was really meant to see if my circumstance was a one off or a wider problem that needed your attention. I have dealt with more than one vendor that could not take ANY criticism of their product or answer any of the tough questions I would hit them with. Eggenfeller is the first to come to mind with this type of mentality. He actually banned me from purchasing one of his engines because I criticized him for changing the advertised HP on his H6 engine almost weekly. J
Anyway, I wouldn’t fly with anyone else’s AP.

Yes, I do “troll” the list. You were also correct that I read your post first thing. The biggest reason that I didn’t get a reply off to you yesterday was that I had to get some information on the things that you posted about. So, here goes…
Yes, we have a small issue in the fit of the new cover over the servo amp board. We have a new vendor for this part, and they had the DB-9 hole a little too far down. This problem has been addressed, but the manufacturer of the part needed some time to get me the new parts. Since the old parts are still useable, they just don’t fit as perfectly as I would like, I elected to use them until they could get me new parts.
The split grommet has been used since the first servo was produced…that is somewhere between seven and eight thousand servos ago. We were however talking about his problem just a few days ago. We are looking at this problem.
As to the pitch servo bracket, I was completely unaware of a problem. Thank you very much for bringing this to my attention. In my research yesterday, it appears that some of our new pitch brackets were not properly bent. I apologize for this mistake, and would be more than happy to send you, and anyone else that has an incorrectly bent bracket, a new bracket that is properly bent as soon as I see them. I should have an update on when I will get the new brackets today.
I am still checking on the length of the bolt to attach the pushrod to the bellcrank. I don’t yet know if that was just a shipping department mistake or not. I would assume so, because I haven’t heard of this being a problem yet. I should have more information on that today as well.
You are correct, we do not yet have all of the drawings together for the RV-10 pitch installation. I do not like that we are sending out picture instead of drawings, but I decided that this was certainly better than no documentation. We are working on these drawings, and should soon have them out. Things are certainly a little tight right now with Oshkosh coming up in 2 weeks and all.
Last but not least, I do appreciate you keeping us in check and pointing out the problems to me. I always appreciate it when people do not just accept what they get as “what it is supposed to be”. Without customer input, we would not have half of the products that we do today. It is the customer that makes our business, and I am very glad that we have such a great group of customers in the RV community. If you or anyone has any problems, you are more than welcome to call me personally. If you can’t get me at my extension, please check with the operator. Many times I am either in a meeting or away from my desk. If I am available, she will round me up. Thanks again.
