Boost software only used on SUPER hugh track...otherwise, there are really no benefit of using it with mod motor. 205 with 4T has plenty of power for track 200 or shorter.....

Here is what I know...Marc won the race at REEDY race in USA (actually, Marc, Victor and Atsushi Hara) all using 205G along with 4.0T motor. (you can find the video on youtube)

Then, Marc, Yanni and others...ran the 323stock with 4.0T motor at ETS event (also can be found on youtube). You can compare that 2 track, the ETS is 50% bigger then the Reedy track.

thanks for the setup, i tried it with boss 13.5t motor 7.2fdr all the way advanced timing works pretty good. just alittle slower than someone use sp esc and v3 motor. and my motor temp was about 140f. i may play with fdr next time

had anyone tried new mmm motor? how about new mmm motor with new 30 degree sensor?

Hi,

what sort of gearing should I be using outdoors with a 45m straight (SP 5.5) ? SP manual says 8.8-10.5 fdr, is that right ?

Nilks

I'm gearing my 4.5T (with a little bit boost) 7.9, so 8.8-10.5 sounds a bit extreme to me. I would say 7.0-8.0 for a 5.5T.

S.A.W

Ok thanks, if I was using no boost I guess I'd need to gear it up (bigger pinion) a little more ?

Nilks

The general rule is that boost = shorter gearing = higher FDR. So no boost = taller gearing = lower FDR.

A friend of mine raced a 5.5T this weekend (though not a SP) with a gearing of 7.0.

So I would start at 7.5-7.7 and start adding teeth to the pinion, until you find the maximum for you (with good temps). Not everybody can handle a tall gearing. If you are easy on the throttle and carry decent corner-speed, you can usually use a taller gearing, but if you use that tall gearing and just go full throttle out of the corners without carrying decent corner speed, you will burn your motor. Trust me - I know from experience.

What size are the bearings on the v3 motors?

MMM Not released for public yet....

But 30* timing ring...it is GOOD...very GOOD.

You can run 205 program (no boost no SC) with full timing (26.25* AMTS) with 5* motor can timing (middle) for FDR about 7.5~8 and you should be fine...

Check motor temp every 5 laps...

thanks solara, you give me motivations to buying the 30 degree sensor. is it good for both boost and non boost race?

for the green sensor (+20 timing) is it adding 1 degree like stock sensor = 2 degree?

This is how it works....

Stock black sensor...adjust from 0* to 10* max
Red Sensor, adjust from 11* to 20* max
Green sensor, adjust from 21 to 30* max...

Because of the design of SP motor, these sensor will act as a INSERT...if you need the 0-10* timing range, you need the black one, or then the RED one for 11-20, and green one for 21-30...you cannot use the green one and dial back down to 2*...or using the RED one and want to have 24*.

I hope you can understand...degrees are degrees, it is not like green's 1* timing = black sensor's in 2*...not that way.

We are still testing the green sensor on 323 full boost...so far, it is the best to set it below 24*....a very good speed with the red in full max position 20* with 323stock....

Using RED and GREEN sensor on 21.5 or 17.5 no timing blinky mode is a MUST....

Clear...?

Solara, what settings have you been testing with so far when using the 20+d green sensor board with 17.5 boosted and 323 software.

There was some testing done by guys here and whatever it was set to it experienced fade at about 4-5 minute mark but motor and speedy were well within temps and not hot. It is a very large track similar in size to the last ETS round track in size and runs will be 6 minutes in TC

Do you have any suggestions ?

I totally know what you are talking about...we have tried using other mfr ESC with similar software and also experienced the same thing..however, the motor were all about 180-190 range and if using other mfr motor, were all above 200*...so they were all fading under the high temp, not like your case when the motor are still warm or not reaching the 180 temp...

They were all fading around the 4:30 and after mark (at least I felt that way but I asked them and some of them not agreed)...we are still looking for the reason behind it and find the setting that will work better then that. However, lap times does not lie...all of us finished the race with the leading pack and are all within sec. from the fast guy.

We were using 1S 17.5, V3 17.5 and even V2 17.5 with adjusted timing. Timing range were all between 20-24*...ESC setting were 36/20 on boost/SC., 0.1 delay, 4000 rpm, 18°/sec ramp, 450/500 rpm....gear @ 6.9~7.2 range.........

G12314 setup our ESC using the approximate setup like above (about 8-10 of us) but running motors from Speed Passion V3, Duo3, LRP X12 and even Thunderpower........all were very much the same, but it might be a little different if the track is bigger.

Our track, by no mean...is even close to the ETS round 5 track. I would guess our track is only 1/3 of the size of that. I bet running boost 17.5 there is like watching paint dry...LOL

Do you know when you expect the MMM motors and timing inserts to be for sale to the public? Debated waiting or getting a 17.5 v3 for blinky racing.
