I have been wondering would Novak ever sell the can without a rotor?? I think it would be a great idea because if someone wanted to own a 3.5, 10.5 and 13.5 and already had a sintered rotor he could just swap the rotor between the cans. It would allow great flexibility for consumers at a lower cost than buying the can and the rotor. Just an idea. No one is doing it....yet.

I'll step up and take this one for Steve. Here is the company line.

Since Steve is a company man and I'm just a Moose I can give you the other answer most people are using. "Throw in your smallest spur and biggest pinion and see what happens" "If it gets too hot. You went too far."

WORD..............
Gear it to the moon and temp the motor, keep the motor @ or just under 175* As per previous mention and you'll be all set.
I have a 13.5 geared at 4.68 and it comes off the track @ 135*, Im just waiting for a smaller spur and bigger pinions...LOL

Gordie,

Interesting Idea... I'll bring it up!

Guo,

As far as 10.5 gearing goes I usually start off around 5.5 FDR... depending on track size you may need to go up or down a bit.

Regarding motor temps... the motors do not NEED to be 175 to operate properly... That is simply the upper limit for the temperature we like to see.

On the lower wind motors such as the 13.5 and 10.5 with proper gearing for your track you may never reach 175! It might just hang out around 135 or so.

Jason,

Yes I plan on racing soon! The last few weeks have been kind of crazy for me...had to go to a wedding on saturday and this saturday is our Novak Picnic Party.... so hopefully come next weekend I'll be running somewhere!

Yea I like mine coming off cooler, seems to have more punch out of the corners with a little higher ratio...

Well Steve,
Summer Slam is next weekend on Saturday...
I think the Novak Picnic Party should be an annual R/C Car race.
1) Novak, great RC products (x)
2) Picnic, food is always a good thing (x)
3) Party, any reason its always fun (x)
4) Annual R/C Race, never a bad idea (x)

Just a thought....LOL

Steve the rollout calc on that page is for direct drive only. I guess that's ok if all the rollouts are for direct drive cars. However, to avoid confusion, you may want to have it edited to include the diff ratio in there for when people apply calcs to vehicles with diffs. Otherwise it may get corn-fusing esp. for newbies.

BTW thank you to whomever made that chart, like I said, nice all - in - one.

Steve,

I had borrowed a friend's 4300 motor for practice, with the intent of purchasing a SS 10.5 for myself before the start of this week's race. According to him, his motor is bone stock with the only adjustment being made to it was the installation of a sintered rotor. After practicing with the borrowed motor (4300), and then bolting on the new motor (10.5) with the same gearing onto my car, I notice a noticeable straightaway speed difference in the car. I had both the 4300 and the 10.5 geared at 5.28 initially, but after my first heat I tried to gear down to 5.1 and even added just a smidge of timing to the motor. It helped a little, but I still got yanked down the straight by people who have so called "figured out" this motor and aren't willing to share their secrets. HELP!

Hi Steve. I have a problem with my spread spektrum GTB. After a 3min run with a 3.5 it slows down as if it is thermalling. Temp of the GTB was 158f and motor 148f. It happened 3 times today and I changed motors and still did the same thing. Any suggestions?? The GTB is a replacement (5weeks old) as the new one lost its smoke after 2 runs. Thanks Tom and Drew

Sticky,

Every motor is going to be a little different...so you may need to play with the gearing and the timing to find the "sweet spot" for your particular motor.

Personally I tend to gear a little lower than most other people would to let the motor "breath" a bit... it is alot harder to diagnose a problem if you are overgeared than if you are under-geared.

Drew,

I have seen a few GTBs here and there that have finicky temperature shut down problems like what you are describing. I would recommend sending the system in to us to have us take a look at it. Please include a note describing what you have experienced with this particular unit.

Mr Page!!

Good to hear from you!!

That chunk looks like it might go well with my growing waste materials collection!

How are things? I've been busy racing at Bending Corners lately now that socal has been spiraling around the drain for a bit... What has been keeping you busy...?
