Hey guys,

Just got an older DB12, with the conversion kit to make it into the DB12RR. I'm most likely going to be running a Novak GTB and Novak 17.5r, Airtronics servo, and a Reedy 4600mah LiPo.

I'm new to on-road, but have been racing on carpet. Anything I should know about racing this or any parts you guys recommend that I get?

A Tekin RS or RS Pro if your track allows timing advance speed controls, to take full advantage of the Tekin you need the hotwire and a computer to set it up.

Find out what tires people are running at your local track, generally yellow rears and lilac or black fronts are pretty common and a good starting point.

If you dont have any I'd recomend the CF hockey sticks, The car is tough and will take a pounding.

Thanks for the input.

Got another question- still need to buy an ESC. I already have a Novak 17.5t brushless motor and would like an ESC with LiPo cut-off.

I would like something that doesn't a whole lot since I am starting out, and have been looking at a Havoc 1s with a low-profile heatsink conversion (can't find height spec for it), as well as a Speed Passion Cirtix Inspire V2.0 (18mm height w/o cooling fan). The SP GT2.0 LPF Brushless ESC is a possibility as well, but I'm not sure if I want to spend that much (although it is 24mm high).

-How much clearance do I have between the chassis and the body?
-Is there anything else that you guys would recommend? (trying not to spend too much)

Thanks again

The amount of clearance depends on which body, and how low you mount the body. As to esc recomendations I love the Tekin RS, its not real expensive andyou can just run in blinky mode if you dont want to mess with the boost and timming issues. Plus its real small and fits the DB12R great(see my the pic of mine). I cannot recomend the havoc, I dont own one but have read about many problems. If you want something less expensive the citrix esc/motor combo is around $100 I think. Also if your running 1s you will need a booster or RX pack.

Thanks Chris,

I think I may end up going with a Speed Passion Cirtix, mainly because they are cheaper (unless I can pick up something locally thats used). Wasn't sure if it would fit or not though.

Hey guys,

Two questions for ya:
-Is there enough room to fit a Spektrum SR300 on its side in one of these cars?

-What is good gearing to run on a track that doesn't have the greatest traction? I'm running a 17.5t motor and I have an assortment of tires, not sure what to run yet. I am just starting on-road though, so speed is the least of my concerns.

Thanks in advance

17.5 guys run roll outs anywhere from 70mm to 100mm, higher will give you less wheel spin on low bite. I would start about 80-85mm and check your motor temp after about 2 min. gear up if it's not too hot. Start with lilac or purple fronts if you have them, and yellow or orange (CRC Gralow) rears. Go softer (double pink or magenta) at the front for more steering if you need it. The receiver might fit if you put it very close to the center of the car. Try it.

Yes you can run the rec on its side but I cannot really see any advantage to this configuration. Lonnie is right on for the gearing and the tires if your running on carpet but the tires will differ abit if your on asphalt. On a side note this car is great on low traction surfaces.

True! If you're racing on asphalt you probably want to start with Purple fronts and Pink rears. That is generally the go to set up.

Thanks for the info guys!

The reason for having to mount the receiver on its side is plainly the fact that I can't afford a micro receiver. My thinking is this- the servo is mounted to the right of the chassis, so I can place an SR300 and a Spektrum regulator behind that, and I can put my SP Stock Club Race ESC on the left side of the chassis, for somewhat even weight distribution. If you guys know of a better way to do this, please let me know haha. Also, what size pinion gear do I need?

Oh, and I live in SWPA, so there aren't any asphalt tracks around here that I'm aware of. I don't think the weather would be too kind to an asphalt track around here anyway. It's usually cloudy with a 65% chance of depression year round here . I live about 2 hours from a a track in Beaver, PA (w/ ozite carpet) and probably about 3 hours from The Gate in Cleveland. I usually race off road carpet at a track called PT Raceway, and it has a low-knit carpet, where I will most likely start running my DB12s.

I like a 76 or 78 spur so in order to reach the big rollouts of 90 to 100mm you will need pinions around 50ish + or -. If your using a different size spur then the pinion size will differ. Are you running 1s lipo? I have'nt needed the spectrum regulator in yrs; but if your going to use a rec pack then space will still be tight.
