Bob, Did you notice a difference when you switched from Tru Track to Dyson AP and rigging?
Hmm, I don’t know Dyson was making servos. Although you would probably get better support than bendix is providing these days.
Hi Bob,
I think you and I exchanged messages about the AP soon after I bought my plane a year ago. I have a similar setup to your old one (TruTrak AP with AFS EFIS) and have thought about replacing the TT with Dynon servos. How do you like the Dynon servos compared to the TT and approximately how much time did it take (in terms of labor hours)?
Thanks,
Vas
Both servos worked well for me. I had the Trutrak servos for over ten years.
The differences are in the head. Both AFS and Dynon EfIS have more processing power and speed than any of the TT heads. Because of that there are more features that TT couldn’t implement.
I added a yaw servo, which I really like.
Some installation notes.
You must use twisted pair wiring on the the four SV-Network pairs. TT didn’t use twisted pairs.
If you are installing a Yaw servo, you’ll need to run separate power wiring outside the sv-network cables. You can make you own cables, the Dynon’s sv-network cables makes your live much more easier for installation.
The pitch and roll servo brackets are almost the same, but there are differences. Using the Dynon brackets will make for a quicker install. Sell the TT brackets with the servos.
My config was almost perfect. The tuning process didn’t make any significant changes.
The amount of labor to install isn’t significant. It’s an easy weekend project.
Overall, I’m very pleased with the upgraded. Vendor support is important for me. Support from AFS during the install was and is always great.
I am very pleased with the solution. It’s worked flawlessly since installed.
