I am reading the last posts since December and i canot find anything about 731c firmware.
Does anyone knows whats about that program?
I am using 4.5T V3 motor and 323 program.
Is the 731 better for mod motors?
Thanks

I originally posted this question on the 12scale thread but this might be a better place to ask.


Question to anyone running an external receiver pack (7.4 lipo etc) on SP v2 esc.

Do you guys still plug all 3 esc wires (Red, White & Black) in the receiver when running a external receiver pack? or do you not plug the RED.

I've tried taking the Red wire out the everything works Ok when running an external pack but is a hassle when changing ESC settings as I need to plug back the Red wire again when connecting to program card.

Thanks in advance.

Why not leave the reciever lead plugged into the reciver, and plug in another one too the ESC end... SP conviently include two length reciever leads in the box, so I've got the longer one permanently mounted into the LCD box now... means i never have to squirel away with the reciever plugs

I will ask again...

Was running 3.456 FDR with 323 software on medium to large outdoor track. Changing to 110 software, how much pinion change am I looking at? Current spur / pinion is 96/50. Thanks

atleast 3 teeth

the pinion size difference varies depending on track size.
I would suggest anything from 4 - 7 teeth .
Only real way to see is to try different combinations.

All right, with my MI4 I had to change to a 106 spur as I didn't have range to go down 4 teeth on pinion as motor was almost against the bulkhead and rear sprocket. 106/46 gives 4.147 FDR. Will give that a try.

tried the 107 VTA class, with a Novak Ballistic 21.5 . took a bit to figure out how to get it to work well, had no torque, so eventually I settled on 10 degrees timing on the motor, and about a 5.00 FDR, and went with a VTA friendly timing of 11.25 (any reason we can't adjust timing in single increments?) .

With this kind of setup, it woke my motor up for the track. I was very surprised how much more punch I had than before, almost night and day. I was worried for a second that my ESC was messed up or something. And temps was still in the 135 degree range after 8 minutes.

thanks for sharing... what are your track dimentions... and any idea if you are running max physical timing on the motor or stock 5 degrees?

I ran my 009 with 96 and 35 with the 107 update i like the low end but need a little more speed? Any ideas? My motor temp was 125f. Thanks

what motor and speedo are you running?

im using the 2.0pro and 3.0motor in the 17.5 class.

Too anyone who says the SP speedo is a bit big... it does fit in almost anything! (only a minor bit of bodyshell shaping need ). Some thinner motor wires and superflexy sensor lead are on their way to make it neater still

Actually tried out a few bits today, switching between the 323a, 110 and 107 Stock firmwares. Have to say, I prefered the 107Stock, but with the timing up at max, and DRRS at 7. Plenty of rip out of the corners, and good (it seemed) top speed. Was a bit hard to gauge as I was the only 12th running round, so was just going off lap time and feel. But for my first time out with a 12th, felt really good

Nice job there Ed.......what motor and roll-out? If I may ask

4cell nimh vs 1s lipo, the extra volt might make enough difference to be able to run the 107 and 110. I found that I couldn't run those on 1s 13.5. If that is a mod set-up you have got there....the extra revs might account for the usability of the new software. (noticed itty-bitty pinion)

Does your set-up run ok without a booster or rec pack? 5, 6 or 8 min run time?
