Thanks, what kind of timeframe are we looking at, i would like something a bit more than "coming soon" , is it 1 week, 2 weeks, 1 month, 3 months. again this weekend the HW422 was laying the smack down, and at this point i dont see any other way than to buy that speedo if i am going to need to wait another couple of months for software

What specific motor (and timing), speed control settings, and gearing (track size too) are you using? You should be in the same ballpark as everyone else.

Something else to consider, im not sure how well your car is handling, but getting a good drive onto the straight is essential to straight line speed. If you get loose on power, or if you have to "square up" the corner to the straight, it will kill your straight line speed.

0 drag brake
med start power
linear throttle curve (-10% expo in radio)
6.74 FDR
From a couple pages back. use those ESC settings, and the middle timing hole for you duo1, and start with a 6.6FDR.

I've got the speedo and car setup pretty good, i can keep the tekins at bay, but i can tell you the HW422 is much faster on the straight, if you read many posts on this board you will see it too. The additional turbo and customizable timing ramp they have helps alot.

Can you help me to translate this to a larger track (80m/260ft straight) and a 13.5T GM brushless motor?

I saw Hara doing a stunning 117 kmh (72+ mph) with an GM ESC on it last weekend (search youtube for ETS 09/10 Rd5 Modified A-main Leg 2). I am not willing to take that risk but I now am short 7-8 kmh (4-5 mph) on the top with the Tekin doing max 84 kmh (52mph).

Do I have to take the FDR down then to 6 or 5.5? It now looks like the car is running max revs halfway straight. Or has anybody got a good start setup for a large outdoor circuit?

I will get back to you after the weekend, I will be running 13.5 on a 160ft straight, so I should have some pretty solid ESC settings.

If you are racing this weekend, I would definitely add some gear, im not sure where your at now but for a track that big you will want a lower FDR. Just keep an eye on your temps (try to keep under 180*F).

Last year I ran a LRP SPX Stock Spec with it on FDR3.27. I already went up to 4.5 and am now gearing it up to FDR 5.7. I need to test again with it cause the revs will come a lot earlier this way and I put the cheat down in revs so it would pick up sooner at FDR4.5.

Also I am doubting the 50* timing, can it be that the engine performs better an 30*? Al least the heat generation will not be that huge.
Up till now (FDR 4.5) the engine never got hotter than 130*F and the ESC not even 100*F

You will definitely want the 50* timing, it will give you way more power than 30*, unless you have the RPM range wrong(too tight), and then it will heat up way more than it should. I will say for this weekend im starting with a range of 6,000-30,000 for my 13.5. I may stretch it out even further depending on how it goes, as I havent had any experience with 13.5 and this ESC yet. A big RPM range like that will give you a broad power curve, and help keep temps down, because you dont apply too much timing too quickly, which can be an issue with the high timing setups that are used.

When you set up RPM ranges, I find that its better to set it up depending on motor, and not on the track. Set the ESC up to get the most out of the motor, and then gear it to the track.

I'm driving with the Spektrum SR3000 system in my Sanwa M11 and read about the problems with mamba and Spektrum. I bought a new Savox (SC1251MG low profile, thought these were in the "good" list) but it is not functioning properly. Also my Sanwa ERG-RZ (which I used previously in the car with an LRP ESC) does not function. When I do some steering the receiver just drops dead and comes back some time later. I now switched to an (old) Sanwa ERG-VRX and this one does work flawless????

Did anybody have had a response from Castle already about these issues and is there a sollution for it?


Also tried some setup changes in the ESC on large track. Started with 50* timing and 6000-30000 cheat timing as suggested.
It looked like the turbo boost came in too late, just half way of the straight it came in. Still lost on topspeed on the Tekin boys
but due to late boost I managed to take some ground at the end of the straight.

Started with 28/74 wich results in a FDR of 5.76. Ik geared down to 24/74 (FDR6.72) and up to 32/74 (FDR5.04) where the last seemed to work best. I now am wondering what the benefit will be by creating the same FDR (5.04) with different spur/pinion ratio. I think I want to go smaller on the pinion so the boost comes in earlier without losing bottem end. Going to start next time with 28/65 (FDR5.06) to see if this improves anything.

Current setup:

GM Pro Stock 13.5T ESC: 50* timing
5000-15,100 RPM range
0 drag brake
high start power

i got 2 runs with my mmp & its awsome!...my setting
FT TC4
FDR 7.5
40* TIMING
NOVAK SS 17.5 @ ZERO
PUNCH DISABLE
START POWER HIGH
RPM 3500 TO 6600
THROTTLE DEAD BAND O.O500 SMALL
THROTTLE CURVE LINEAR
MOTOR TEMPS 122 TO 125
85*DEGREE WEATHER
120 FT STRAIGHT
i been reading some ppl setting 50* timing fdr 4.5...to me thats sounds like alot...im running with all tekins & most of them are gear around 5.5 or less & im just sayn on the straight I was slowing down for them so i would run in the back of them...so i couldnt imagine...useing some of the setups i been reading...my car would be too fast...Unless its a straight bigger then 120ft..this was my 2nd time out with mt mmp & so far i love it.....BTW we had 15 17.5 cars yesterday & i qualify 2nd in the A....JUST wanted to share my findings

Anyone have a setup for 1 cell WGT with a 13.5, large ashpalt track??

I looked but didn't find anything.

Thanks,

Seems to be working well. My motor is getting hot quick though have had to bring my FDR closer to 7
