    Default Trim relay

    Found a product that might be of interest to some of you that like to experiment with your experimental, especially if it saves you a few $$.
    It's a 10 amp forward and reverse relay module. Should run off the GAD 27 or GSA 28 outputs just fine to power the trim motor.

    Ordered one today. I'll report back when I do some testing.

    That would be two of us. Seems like the other options are more complicated than they need to be and this looks promising.

    It appears it is nothing more than a multi pole 10A relay with LED lights in a nice case, but $12 is hard to beat.

    Did you end up using this relay? If so, enquiring minds want to know how you integrated it.

    Heya Mike,

    Seemed to work fine but in the end, I decided to use the Safety Trim servo controller from TCW Tech.
    I have had so much disappointment with Chi-Com quality control in other stuff that I'll repurpose it in something not so critical as flight trim.

    I used the big brother to the one in this post and it has worked great for 300 hours.
