The fact that the system you are looking to buy has been discontinued, should send up a red flag.
Novak are not now, nor have ever been a major player in the 1s competition market, for what ever reason ?
Perhaps there's far more to gain in the mainstream market, but that's pure speculation on my part.

I have no reason to think the Havok would be problematic, but it wouldn't be my 1st choice.

Thanks for the good opinions on the Havoc 1s.. the fact that its 1s only isnt an issue we have 3 or 4 2s systems in play already.
the fact that its discontinued does raise an eyebrow but an earlier poster said his is fine...

Its a $160.00 experiment. if we get deep into 1/12 and want to get more serious with the GOOD stuff it should still be a good enough system for a back up car.
Thanks for the 2Cents worth guys and if anyone has another opinion im still listening.
now to figure rollout for our little track and get a range of pinion opinions...
these we shall glean from reading more pages of this thread.

I went down the same road you're looking at, about a year ago. Word of advice from someone who's been there, done that....DON'T!

Novak never has been a major player in 1S. The feel of their speedos just isn't up to par with everyone else.

If you buy the Novak, you're stuck with it. There is no secondary market for used Novak 1S equipment other than landfill ballast.

If you buy better quality, and better suitability and decide that you DON'T like it, chances are almost 100% that you'll be able to sell it quickly without taking a significant knock in the wallet.

Oh, and better stuff will help you unlock the potential and fun of 12th. NEVER regretted buying good batteries, good motors, and good ESCs. But I do regret the orange stuff.....

IMHO, even used first line equipment would be a better choice.

Thank you for your humble opinion andits noted... we COULD start some sort of wild A$$ 1s dragracing or something but ya its landfill if its not getting used but still half the $$$ of a LRP setup. but i really want a murfdogg just cuz its gotta good reputation.... well not really i just like the colour lolol

we have been down the chinese road both for batts and esc's and motors and while some have been trouble free, some have been problems and theres just nothing like going for a drive to play with your toys and having to pack up and go home to your computer to start ordering new stuff and hoping it comes in time that you dont miss ANOTHER race day the following week...
we put a lot of miles on these things and wore 4 or 5 sets of foams completely off our MRS4's last year so reliability is important. With 1/12 scale smalll things like "feel" have gotta be important too as one little twitch can be bad ( and thats just the guy on the radio).

Hmmmm LRP.....Hmmmmm
i think possibly so

Hi Guys,
About to get the new serpent 120LT and noticed it doesn't come with a spur gear.
Being new to the 1/12th scale arena I have no idea how to work out what my spur gear starting point should be.
I've searched and it seems that most are around the 96 tooth size.
I've got a rollout chart that has 88 96 and 100 spur gears on it. Should I start with these?
I also have no idea how to work out my rollout as I have no idea what it should be and also as far as I know no-one runs 12th at the local track.
I've done some measurements on google earth and the main straight is about 40 meters or 120ft. The track line then is pretty much up to me but there are some technical corners with one or two sweeping corners and then a few hair pins as well.
I'll be running a speed passion cirtix and 13.5 turn v3 ultra sportsman.
Initially it'll be stock and then as I get better i'll mod it up and might upgrade to the gt speedy.
Any help would be greatly appreciated.
Cheers

Go HERE for tons of info about 12th scale building, setup and such.
One of the many links on that page is to gearchart.com, the ultimate tool for rollout calculation.

That's a good size track, for 13.5 no boost, you might want to start at around 90+mm roll.

72T to 78t spurs should be good for what you are doing.

Hi Redbull,
Thanks for the link, i've read through a fair bit there already trying to get my head around the setup of 12scale cars.
Its easier but harder than tc it would seem.
90mm rollout? Wow that heaps! according to the gear chart i'd need a pinion of more than 40 tooth with a spur of 72 and tire diameter of 50mm...
You say its a big track for a 13.5 no boost, should i run boost to get the most out of the car?



This is the track is pretty good with a TC

Now that I think about it, with that Cirtix you may need to be over 100mm roll.
I think that's about the same size track from the ROAR nat's in Jersey this year, and they ran 13.5 blinky.
So yes, 72 spur would be good.

We were running 72t spur x 58-60t pinion at the iic race last week with 17.5 blinky

Most of the 12th scale setup is tires, and paying attention to the little things on the car, like toe, camber, and tires coming unglued around the edges.

At my track 13.5 boost I find that using a spur in low 80's work best. 76 and smaller is better suited for 17.5 gearing.
E

+1
Except 13.5 & 17.5 blinky are not too far off on roll.
We saw that last week at the iic

Lots of info in how to calculate rollout but how is the rollout determined. In other words how do you know that your track requires a specific rollout for the intended motor? Is there a method to figure this or is ths just an empirical number?

In all my years of RC racing, gearing has always been "socially engineered" at the track. However, it would be nice to know how to determine it on my own.

Hopefully that will work to give you an idea of the track.
Ok cool thanks heaps for that i'll start looking now for some big spurs in preparation. 72-58/60 hmmm maybe 100 is not so bad...
If I upgraded the cirtix to an sxx or rs pro could I get away with less rollout?
Still trying to get my head around the whole esc thing with 1s as well. I've been away for a few years and ALOT has changed. Lipos had just been made available.
Would i be better off going with a booster and the RS for such a big track to ensure easy running? I noticed the TQ booster comes highly recommended...

There is no real science to determining what roll out should be. Typically people just take an educated guess and try that. From there they go up a bit and down a bit and watch what happens to the lap times and keep adjusting until either your times no longer get better or even start to get worse. Every track is different in size, layout, and grip...so there is no formula out there that you can use to plug in the variables and come up with a roll out.

A Tekin RS with a TQ booster is probably the fastest setup for 1s racing.
However, the LRPSXXSS is much easier to work with, just 2 buttons, and no pc mapping required.

There are many other options for boosted esc's, but those are the only 2 I have experience with, and are by far the most popular at the races.

Based on 17.5 boost vs: blinky, you're looking at a 20-30mm roll difference.
I would imagine that would carry over to 13.5 as well.

Deepsouth indeed
Tasmania, wow !
