Default Noob in the house.

Hi everyone, my name is David and i'm new to the game... I'm sure i will be on here alot asking for help and advice. My father has been in this game for a decade or so and decided to hand me over the keys to his cars. He will assist me as much as possible but it would also be great if I could make some buddies on here along the way. I am inheriting his CRC Razor II and a Losi spint car along with his entire setup (tools, parts,etc..). If anyone out there has any words of wisdom on the first thing I should do please feel free to drop me a line.

Most likely, yes.
By the way the body is a closed cockpit.
Some one else asked earlier.

Thanks for the replies everyone.

It would be great if someone brings out a lipo saddle pack that will drop into a T-bar style car. I ended up getting a 12r5 but i have a cyclone touring car and like the hotbodies brand so i dont really want to get rid of my cyclone 12s.

With regards to battery capacity. My friends seem to think that the track which is being run for this years nationals is going to chew through the power. It's bigger and has more grip than what we normally run on. They are gunna be strapping in some hefty motors. Personally im a little skeptical that we will need that much capacity but i aint really got any 12th scale experience so im erring on the side of their advice.

But ultimately cells are getting more expensive to buy locally in australia and i also dont trust the stock which is around. So whether i like it or not lipos are coming.

I have posted pictures of my CRC Xforce and although it’s not a readily produced car I am just pointing out the problems and experiences I am having with lipos. I did run it with a TForce in Memphis at the Beat the Heat race and only lost by .25 seconds to an xray with a 5000 40c thunder power pack. Not bad for my first time running lipo in a 12th scale. I ran a 13.5 EA duo and my SMC 4000 25C took about 2500mah to charge back on a 160x80 nitro track with VHT. My rollout was 3.44” or 87mm We turned 22 laps at about 22.5 seconds per lap average. Now in my TForce I was running the thinner .090 chassis which allowed me to place only 28grams extra to balance it out with a 9602 fatuba servo and spx speedo and Novak battery booster bringing me up to 735 grams. Not bad but I figure if I was running the CRC thick .110” Tforce chassis I would have had a little trouble to get down to weight and still be balanced. So when I transferred to carpet and put in my 17.5 I had stuck to the same gear as the carpet track Thunder RC is 92x50. went out and ran 12.1 second laps. For reference I have turned 11.2 on the same layout and EA turned 10.8 on the track with 4cell 17.5 I geared up 2 teeth to 3.64” 92.5mm rollout and turned 11.6 laps so far. Weird enough I think due to the higher bite I have had to put 2800 to 2900mahs in the pack to recharge it. Now for the bad news, Donnie Lia is a goober telling me I can balance it out to weight, to balance out my car I have to add almost 45grams which puts me 35grams over the 730gram weight and that’s with the lighter SMC 4000 pack. So does anybody know what the weight difference between the 3 packs available? Because if I actually got a good 40c 5000 pack I would probably have to add another 20 to 30 grams to the left side of the car plus what the battery is using to balance it back out. This would put me in the 800 gram range which is a serious disadvantage. I mean I have a micro DSM receiver in it. I can’t get it any lighter. People running the 5000 packs in tplate cars are you have trouble getting to the 730 weight limit?

I have a CRC GenX, and I will be running in 17.5 Lipo. My question is, what is a good setup to start with running on brand new carpet. Also what would a good tire combo be. Thanks ahead of time.

Default RC12L3o for road course.

How would a 12L3o handle on a road course with a lipo on the left side and electronics on the right. And does a brushless fit the rear pod? Any modifications or parts required? Thanks!

Default Corally 12X pinions

Hi all

Need a source of long shank pinions above 35t that Corally offers. I am running brushless 17.5 and 13.5 with PRS 76/80 spurs and 45-50 pinions. The track width can sometimes allow the pinions to wobble due to the short shank of the pinion. Any other sources or suggestions?

The Niftech motor shaft extender is a viable option here. Not inexpensive, but (like everything else Ray makes) is incredibly precise and very useful. Also, the expense ($22 in this case plus shipping, etc) offsets the need to buy the oddball pinions. In fact I wouldn't at all be surprised if the need for "extended pinions on the Corally cars was the impetus for Ray developing these.



I just picked up one of these for my Novak Mongoose 380-sized motor car I'm experimenting with.

There is a possibility that the shaft coupler could interfere with the pinion boss if run "right way 'round" but reversing the pinion so the grub screw is outboard (like off-road cars) would solve that.

Part number is #4001

You can contact Ray and Julie (possibly the nicest people in RC!!) at 440-257-6018...tell 'em Scott in Montana sent you. Dig through their catalog and you'll find other great stuff. I swear by their traction compound ('cept you guys are required to use Jack ), their diff lube (in the syringe), bearing lubes (for ball bearings and motor bearings), their alignment tool for 1/8" axle pan cars is a MUST HAVE item for 1/12 racing as far as I'm concerned, reamers for steering blocks and axle height adjusters (though less critical with the IRS adjusters than the old Associated ones), and on and on. I've got scads of their stuff in my race kit (and duplicates on my bench at home) and have never regretted any purchase I've made from them.

When I was looking for larger pinions for my 12x I was told that none were avalible above 35. I think thats because corally really only designed it for brushed aplications but I may be mistaken on that. The only optiions I could find were the extender that Scottrik posted or change to a bigger spur.

Yes. And for those that don't look at RedRC.net very often, here is the infomation and pics of the new body:

Dumas had one of these on his car two weeks ago at our track, and his car was hooked and flying better than everyone.

Guess beauty is in the eye of the beholder. But it does look like it would glue a car down.

With 13.4/1c lipo how much drop off are you all seeing in lap times from the beginning through the end of the race? Last night my car feel off about .150-.2 on lap times over 8 min but I think my car is one tooth over geared.
