Got my 17.5 today. I soldered it in and went to adjust the timming and loosend the three screws and it wouldnt turn any direction. I loosened it up almost where the screws were coming out and timming still wouldnt move. Took the motor out of the car loosened the three main screws holding motor together and timing finally moved. WTH Something is wrong with this picture. When the motor screws are fully tightened the timming endbell cannot move even with screws out. Can anyone tell me whats wrong! thx

Thumbs up

Nothing is wrong with your motor, and that's the way to change the motor timing in most other brands too: Novak, etc..... You don't have to overtighten the sensor board screws anymore to keep it from moving . You do have to check your rotor shimming though after retightening your main screws.

Just read three or four pages of this thread and found out whats going on. How would I know what batch of motors I got. Will have to break out the drimel cause yes my timing only goes up to 20ish too. New motor!

20 degree mark the most you are suppose to go to . The motor has 30 degrees at the "0" mark . This was mentioned several times a few pages later on .

There was a lot of confusion about this when the motors first came out and when this thread started .

The timing is only supposed to go to 25. There is already 30* built in. So you don't want to run more then 25 on the endbell. No dremel needed.

So, I'm interested in a D3.5 21.5 turn motor. We run a variant on the VTA class with 21.5 motors locally. We are just about to start carpet season. The back stretch is about 70-75 long. Would I be happy with a D3.5? Is all that extra kv (and RPM?) going to be useful to me? Or, should I just stick with a Revtech 21.5, which has less kv? Thoughts?

I would definitely get it. You can gear it really tall if needed and still have a ton of rip on the infield. You could prob add 2 teeth to your pinion and still have better rip then the revtech and be able to have more top end.

Got it figured out! I did have to dremel a little bit inside the the housing where the sensor board moves from side to side. Some solder tabs were rubbing not allowing the sensor board to move smoothly.

Anyone have a good starting point for the D3.5 21.5 in USGT on a 90 x 48 track that flows?

There's no denying the d3.5 is a good motor, I really like it in my buggy and 2wd sct, but I did not love it in my sedan. I much prefer a reedy or a schurr speed. The thubderpower with the right rotor is great as well.

Try a schurr speed 13.5. I love mine. Super smooth with great power everywhere. I'm at a 4.3fdr and 40 degrees of timing and its killer.

I think 3.7 could be a bit high for a track that size...I would start closer to 4 and work down as the motor can handle it.

For boosted I think you'd want to be like 5.5 or 6. It's been a while, but I'd think 3.7-4 would be blinky range.

Yeah I would personally be around the 4 range to start in blinky.
