    That small change to the mount design on the frame will make a big difference and should be easy to implement as you are using profile aluminum.

    This modification will I be easy. I have more aluminum profile and I can also lengthen the threaded rod ball joints. I already want to put it into practice but I need time and these days I am busy with family

    Much better @Chumet1, I am looking forward to your tests. It would be great if you can do a little video.

    As I can make a video with improvements. Actually improved the feedbag. But I have a problem with the left engine, you do not get rebounds and adjust the PID. I have to do tests to see if the motor potentiometer and pololu. The left and the right are identical and the right engine performs very well.

    I found something interesting.
    With the motors, even though they may come from the same supplier , one gearbox moves easier by hand than the other, then requiring different PID and motor power settings.
    My dual racers, even though they are the same, the red one has gearboxes that move more freely than the yellow, hence I had to spend more time on the red racer getting the settings right.
    Another situation, I put together motors and pots for @Rastus and one gearbox moves more freely that the other. Weird, but he sorted it with PID and motor power settings.

    I have solved my problem rebounds in the left engine. It was unsoldered connector poplolu and to end contact with the motherboard. It took me quite repair and re-run the pololu. Now both engines work just as well. A big step to adjust them properly. I'm happy.

    Such a great support especially of @bsft! Many builders would lost in space w/o him. This has to be said for one time. :cheers

    very good job

    I like the aluminum structure
    you buy the structure on the net?

    Another problem I have encountered is that the potentiometers are degraded and give false feedback signals, the cause is not well aligned with the motor shaft and being fixed to the base, sometimes the motor bracket gives a little and force to the shaft of the potentiometer.
    yesterday put the potentiometers on the same engine and well aligned with respect to its axis and at the moment give a very good answer.

    And a question, I see that many use quality and multiturn potentiometers, which recomentarian me ?? I have some very basic 10K, as I show in priemras photos.

    I have found that good either alienated than a very accurate feedback of the actual motor position potentiometer is essential.

    +1 Hall effect's are where its at. And Do yourself a favor and use some flex couplers. Takes the guess work out.

    Thanks for the infofmacion. I'll buy them as simply having properly secured my current cheap potentiometers movement improved a lot. With these potentiometers you say me and those pieces to protect their axes have to do better still my project.
