supastox speed help

[adprim]

hi, I ran my supastox for the first time, and I was being over taken by pretty much everyone down the straight and round most long corners,
im running 70t diff, I tired 26t,31t&35t pinion and still slow,
im running 1s turnigy one cell gen 2 and turnigy 13.5
any help please

Have you checked your end points on your radio are set to 100% for full throttle. Then you may need to rebind your radio to teach the esc again

Did your car get faster top speed when you went to a bigger pinion or did it make no difference.

[adprim]

it was better with the 35t on but still a lot slower,
I will reset and check the end points and reset the esc and take it from there
what gearing should be best, a lot were running 66spur ?

[luniemiester]

With gearing it's best asking what others run to get you in the zone. Also depends on what diameter your rear tyres are as the rollout and gearing are a combo.

A few things to consider...

If the change of ratio makes little difference - what is the timing on the motor? In a GT12 try around 40deg assuming that zero on the markings at the back really is zero.

Cells - how old are they? If they've seen a bit of action the internal resistance might have gone up to the point where they don't deliver the volts. If you can try someone else's cell with the same settings as when using your cell it will give you a clue.

Although you've been up and down the pinions, what size tyres are being used? Assuming that you are using 46mm diameter tyres (my best guess!) then...

On a 26T pinion that is 53.6mm/rev - too low. On a 35T pinion that is 72mm/rev - arguably a little high but if you have no timing on the motor it would explain why you saw little change in speed. On 40deg timing aim for 68mm/rev to start with.

The evidence you have given us points me to the motor timing, cells or the end-points issue already suggested above. Come back with more information and we'll help some more!

Have you made any adjustments to your speedo?

Im only a newbie to gt12 myself with my sons car, he had a similar prob

After asking lots of question from lots of people was adviced to adjust the timing up on the motor but keep an eye on the motor temp as you dont want to overheat it, and turn up the punch settings in punch1 and punch2 to max which was 30 on his speedo (toro)
The other thing we were told was to disable drag brake, cos you want to carry as much corner speed as poss, hence you dont want the drag brake slowing you down. if you need to brake you need to do it yourself conciously.
As also stated above, talk to the club members pick there brains find out what roll-out they run for your track, there the best people to ask and most people ive come across have been great and more than willing to help.

If your motor is the newer red one then these are the settings:

motor - full timing (endbell rotated as far anticlockwise as it will go.

esc - boost 0, turbo 0, 1st and 2nd stage punch 30, 1st and 2nd stage brake 25, drag brake 0. Leave other settings alone. *You need the program card to do this.

gearing - around 68mmpr. That's a 30t pinion, 70t spur and 50mm tyres. Go up 1t on the pinion for every 1.5mm drop in tyre diameter
