Ooops sorry, I'll let you win one heat tonight for correcting me!

kawirider,

Yes that would be right with the spur pinion and tyre diameter.

with regards to run time, i suspect you would make run time, however, runtime is dependent on many factors outside of what you have listed.
Track grip and layout/size, driving style, speedie (or speedie settings).

You may make runtime with a 5.5, im gunna guess you wont make 10 minutes with a 4T
You will know when the battery dumps the car speed will start to drop off quite markedly.

Hi I am new in 1/12 scale. I am wondering which servo is most suitable for this scale. I am running on Cyclone 12 thks for adverise.

Theres acouple to choose from.

Futaba 9650
JR Z-3650

Hitec doesnt really make a suitable servo for this scale.

Shawn.

Heres a low down of my 2010 New Zealand nationals winning setup for my 12r5.1

Electronics:
Spektrum Micro
LRP SXX (with heat sink)
1s Lipo 5000mah IP
2s rcracer receiver pack
tried variation of 4.5t X12, 4.5t Novak Lite, and 7.5 X11

I began testing with my 4.5t X12 LRP but it had too much torque for the traction at Christchurch, and it was getting too hot for me to gear it any taller. my Novak 4.5t lite wasn’t soo bad, as it has a smoother torque range, but that and the LRP were sucking out most of 1s Lipo battery, and there’s nothing worse then if you are in a final and you are unsure if you are going to dump or not. I put in my LRP 7.5t X11 (same motor i ran at the last nationals), and there was a lot less torque which was good, and I kept gearing it up and up and up, as well as cranking the timing on the ESC until it reached the perfect temp. I originally started with a gear ratio of 96 spur 35 pinion, and ended up at the end of the weekend with an 88 spur and a 46 pinion with the motor running at 60 degrees, and only 3300mah used in the whole 8 minute race. I think a 6.5t motor would be perfect for the track.

I tried the jaco double pink front tyres throughout the weekend also, but it gave too much initial steering, and the tyres wore out extremely quick.

Changes I made to stock setup (which can’t be seen on the setup sheet):

* Put shims either side of the front wishbones to make the front wider, which settles the car down greatly.
* Put 1 more rear shim in at the back each side to make the rear slightly wider for more mid-exit corner grip.
* Used the Small ackerman shims for slightly less steering
* Cut the center shock shaft 10mm, as standard it wasn’t giving enough forward droop
* replaced carbide diff balls with ceramic

There are a few videos of the pro12 finals here (mine is the pink and green car):

What are most guys finding is a good starting diameter for their tires.? I'm coming back to 1/12th after a bit of a break, and the numbers escape me.
Also, what's a decent rollout to start at for 1s 13.5?
Thanks,

Danny

The futaba servo fits best in the HB car!
I have them both and I found that with the KO servo I had to shave down the ant. mount to get it to clear

I highly recomend getting the optional Center servo mount too

Thks for the info

Cut rears to 43mm, fronts to 41mm. Rollout depends on the track, conditions and ESC, etc.

Looks really nice! Wish we had something like that out here! We do have a nice outdoor track but I'd love a nice indoor carpet track.

I can vouch for this track, it IS AWESOME!!!!!!!! Sweet carpet surface, great amenities and the BEST pit chairs you will find at any track! Plus the track owner is a really cool guy!:nod::lol:
