Default Pitch trim connector

Hello everyone, new to the board and already asking for help. Iím helping a local RV14A builder with his bird. Today we debugged a problem with the pins in the connector at the tail for the pitch trim. We need to order a new connector and the correct pins, thinking Digikey will have them but was hoping someone could help with part number for the connector. Picture attached. Any info would be appreciated.

Digi-key part number for the male housing is 43020 and 43025 for the female housing. The connector part number is 43031 and 43030 for male and female.

Good luck

Many people (including me) have found the micro molex connectors to be nothing but trouble. I replaced most of them with better connectors. Many options including d-sub and Deutsch DTM.

Do some searches and you'll find lots of information.

I spent a day ringing out the pitch servo wiring to finally find the intermittent connector in the elevator on a buddyís build. I cut it off and installed a better connector.

Great call, I also found the connector to be a bit flimsy and the pins just wont take hold in the housing. Iíll do some research and seek out a more robust solution.

I had the same problem yesterday as well. Replaced mine with D sub connectors and heat shrinks. Steinair has a excellent video on how to do this.

I don't recommend a field install of the micromolex connectors. If you bugger the supplied pins replace with something better. The pins are not designed to be removed and reinserted.

For that location I recommend using d-sub pins incased in shrink tubing. It's a common trick outlined in the Aeroelectric.

Please note that the pins go in and lock in place only in one orientation, once it is in the correct orientation it stays on well but I admit they are a pain to work with.
The elevator trim is the only place that I am using the Molex micro, other locations that does not have that nice slot for the connector to be mounted, I am using the Molex mini which is a bit bigger and easier to work with.

This is a VERY important point when working with micro Molex connectors. If they are installed incorrectly, you will have nothing but problems. However, once crimped properly, a feat in itself, and installed in the correct orientation, they work as expected. However, I understand why people would want to replace them.

The micro Molex are so difficult to crimp it's a joke. Even then (using connectors crimped and inserted by SteinAir) I found them unreliable. Regular Molex no problem.
