If I remember correctly, the Track Power packs are gold in color and they are not very fast. They lack punch and may not be powerful enough to supplier the amps needed. I am not an electrical engineer, but from my experience on the track, IP 5000 40C or SMC 5200 50C are the fastest packs. Try one of these packs and I am pretty sure you will feel a power gain. Also note that you may need to run different gearing with different battery lipo packs.
Hope it helps

Ok,
I'll change my ratio.....
But isn't the stock spec 9.5t not an motor for just more toque instead of RPM.
I think my ESC was at it's 120Amp limit so that's why nothing overheated.
I orderder an spx so i'm changing my FDr to 6-7 and start from there with (easy)trying to gear it good.
The strange thing is:
in the manual of the motor it says to gear it 7 for short tracks and 5.3 for long tracks.

Ran the SPX setup last nite. 4.2FDR in a Cyclone with LRP X11 17.5 Brushless motor on Profile 7. Car felt awesome first 5-8 laps and after that the car seemed to slow down a bit (not as punchy), not much but noticable. This is using a fully charged IP 5000mah 30C lipo, so power shouldn't be a problem. Has anyone else experienced this? Is there anything I can do to fix this? The motor came off at around 50 degrees celcius (130F), so it wasn't being overheated. I was even going to gear it higher to 4.0 to see but didn't have a chance.
Mind you this could be just me, but would be interesting to see if anyone has experienced this.
Cheers

You know I have the same thought on that. I run profile 8 though, and with a smc 5200 40C it felt like that. Motor was coming off at 145 after 6 mins, esc like 110, (it was pretty cool out that day). It doesnt feel as fast and snappy as it does the first few laps. I thought my motor was maybe getting hot the week before and that was why. But my last race day it did the same thing. I tried a ballistic motor out in practice last weekend and it didnt seem like it faded off like that. But I will have to test it on a race day to really find out. I could just be getting used to it, but I duno.
what i will be trying this weekend is fdr 4.6 and above with profile 8 as suggested by few folks on the thread... will keep you guys posted on progress

Yeah I thought it was me too. However the car still had great top end speed but just didn't seem as punchy. May have to play around with gearing. But from the temps it seems quite conservative. I will be putting the heatsink on the SPX shortly to reduce the temps on the speedy, not that it was getting overly warm or anything but may help.
but what solved the problem is a re-do with the set up settings and all was fixed... easy and pain free
good luck

Try this : recalibrate withe throttle EPA @ 100%. Then , once complete, bump EPA up to 110%.
My Duo 17.5 comes off very cool,yet is one of, if not the fastest cars at our track in stock.
I level peg it with the others on the straight and pull away from corner to corner.
One heat a few weeks back for instance..fastest lap was #3. On the second last lap, it was only .1 off.
I run punch #8 / 44.6mm rollout. W/ IP 5000-40c.

Hello,
I was wondering.
I just bought an spx stock spec.
What's the best gear ratio for use with an Vector x11 9.5t stock spec engine for having optimal use with the ADPC program 8. i'm not looking for the best driving time, but the fastest gear ratio. I'm now running 5.02 and when i keep the car in my hand it jumps into the second gear effect en goes boom, but on the road it doesn't have that. (i didn''t pull full throttle though, because it's insane.....)
I suppose i have to gear it to 6 or 7.
Does somebody know what the handbrake mode #3 is for? It's not an automatic brake since that's in mode #4.
Greetings,
Stefan
