SXXSS v2 is what you want.
The mkIII was an update to the older v1 hardware which has been discontinued.
And yes, in most cases the LRP can run with any of the boosted esc's, when setup, and geared properly.

Hi,

I'm running this speedo with a X12 (13.5t) and not sure if I need to gear down alot ? Today I tried,

3,3,3,0 5.98 Temp 59C
3,3,4,0 5.98 Temp 80C
3,3,4,0 6.37 Temp 79C
3,3,4,0 6.21 Temp 82C
3,3,4,0 6.61 Temp 81C

So I'm not sure what to do, gear down even more ? no point in putting boost to 5 as it will just add more heat.

Thanks.

All those temps are fine with that motor!

So what was fastest?

I'm going to assume this was on an out door track?
Which firmware, 4.2 or 4.4? 4.4 will lower motor temps significantly.

My thought is you are not running enough boost or you are under geared for what you used. Running 2s I do not recommend using even boost numbers. Fast ramps create more heat and generally are not faster on the track, plus they are harder to drive.

I ran TC 13.5 but on indoor carpet, went back and forth between boost 5 and 7, gearing was 6.2. Had more power than the track could hold and motor temps were usually 70-75c

4.4 and yes an outdoor track with a 45m straight. Shall I try gearing back upto 5.98 and more boost then ?

Has anyone tried a Thunder power 17.5 with this speedy yet in Boosted TC, and if so what did you find as a good starting point?

Running on an indoor carpet track with 4.4 (30mx14m) i tried 3-5-7-1 with the 2 dot insert and geared at an FDR of 8.0! Temp after a 5 minute run was 64c using a fan on the motor.

The car was very fast but did start to lose speed to early on the straight, I think somewhere between 7 - 7.5fdr would have been better, I will also try turning the boost setting up to 9.

I have tried the even numbered boost settings, and as Sean has already said, it dosn't make the car any faster, it just makes the car more difficult to drive and creates heat.

I'm running this combo right now. Just got it, so I'm learning it. One thing is, you must run endbell timing. If you do not, the esc boost will not kick in. So it will be like you are in blinky mode. My current setup is 0/10/12/3. Endbell timing is 15 with my gearing at 5.56. After a 6 minute run on a track with 16-17 sec lap times and air temp of 80 F, no motor fan... Motor temp was 180 F. I'm still learning what Mode 3 does, but that might be a start for you. If you are scared of the motor temp, try a fan or try 0/10/10/3. Hope this helps. Like I said, I'm still learning this esc. I just got it a week or so ago.

Thanks Jimmy, Have you had the opportunity to compare speed and lap times against othe combos and if so how did it compare ?

So you ran max settings while overgeared for far too long without checking temperature, and you're mad at LRP for your cooked motor?

If you'd gone to profile 10 instead of 12, you would have cooked a motor too. The even profiles for mode 3 are fast ramp, and are entirely different than the odd profiles that are slow ramp. Stick to odd profiles for 2S applications. Or, better yet, stop trying new ESC's if you can't be bothered to learn about them, or follow common sense when testing new settings.

I ran the Nosram version with 4.4 and a D3 on the weekend at the Muchmore masters event in Sydney Australia. All the competitors agreed that this was probably one of the closest stock events for some time and the speedy and motor combo was fantastic.

I qualified 2nd overall with some fastest laps in certain rounds and the speedy was so smooth and drivable that it made it feel slow but the times were saying it wasn't.

I ran 0-9-12-0 and ran the D3 with zero timing and an FDR of 5:3 in a T3-11, also ran the new Nosram 6200 65C. Air temps were around 19-20c and the pace of the event meant everyone was pushing extremely hard. I felt I did not lack anything against Tekin, HW, Speed Passion, Kinetics and ORCA which were all in use in the A Main

B4james, I haven't had a chance to run this ESC with other motors. Running against Tekins has not been a problem once I got the boost to kick in. Good to hear you got it working with the D3. I have yet to try one. Interesting to hear that it worked with zero timing. Running the ThunderPower with zero timing didn't work too good. No boost. The Tekin guys would zip by me like I was standing still on the straight. I didn't get to race this past weekend (damn customs held on to my shipment to fix my car!). But I'll do some more testing this coming weekend.
