Just received my Duo 3.5 motor yesterday and can confirm that grinding was necessary to allow timing adjustment past the 20 mark (on both sides). Very unfortunate having to do this with a brand new motor.

Unfortunately adjusting timing is still difficult as I believe the aluminum cover (with the holes for the sensor connector and 3 screws) is too tight fitting. I gave up on this and wrote to Trinity, will see what happens.

Nothing new. My old Duo3 I couldn't adjust the timing without taking it apart and sanding the cover till it was able to turn. Anyone else have problems with the sator tabs coming loose and shorting out? I have had 2 motors where the tabs have come apart and wiggle around till they touch and short out. They are great motors, i just had quality issues with them.

That is indeed an unfortunate confirmation, I'll await for Trinity's response as I think this is just too much to require the customer to grind additional material and sand the cover just to get a properly working motor. I'll hope for a good resolution otherwise this D3.5 is going to the trash.

took less then 5 minutes for me to dremel out the material that needed to be cleared to get full timing, didnt think it was that big of a deal

If it goes in the trash let me know I will buy it/trade for it.

Shouldn't have to do any grinding/sanding on a new motor after shelling out $90 or so to get it to work properly!!! Poor manufacturing and quality control I'd say!!!

I also believe that if it is teched at the nats they will look for that grinding and dq the motor. Especially with everyone talking about it.

The second batch of the 3.5's will be punched properly ....... The first batch were a total of 80.....The new batch will have a "more range to adjust"....This does not mean that max timing is the "way to go".....In testing this year on these motors one thing I found is that each motor needs to be played with in-order to find there "sweet-spot"......In other words ..I took two identical motors and found there sweet-spot and both were at a different timing mark.....

Now another point that has to be made... is that the ambient temperature outside is a major consideration to where you end up in gearing and timing....if your racing outside and start in the morning and you temp your motor and it's 190 thats great!...but in the second and third qualifier if the ambient temp goes up you have to be ready to re-adjust your timing or gear to stay at that temp....these brush-less motors are very susceptible to outside temp....so watch it....

I hope this clears things up a little......any more questions or concerns please feel free to ask here....I will try to help................................
