i was looking into a mamba Max 5700

Thanks!

Any other Newb 12r tips would be great!
Typically and I'll be biased here Tekin, LRP, Mamba alongside of the Black Diamond speed controls are all decent products to consider. Personal I have the Tekin, due to features it offers and adjustability. Again that's what I personally run, other opinions will differ. Consulting your local track will help you decided that best fits you along with "trackside" support.

Accordingly the 1/12 type cars incorporate a traditional 540 sized motor. So, any 540 sized motor or for sake of being motors that are aimed for 1/10 will fit a 1/12.

Tips? Here's a few links that I favor should help you..
Mark Payne's 1/12 Notes
Richard Chang 1/12 Notes
I'm sure others can input sets ups, guides and so forth..

Personal tip:
Previous to owning a BMI I did run the AE 12R5 non brushless. Make sure you build the center shock to factory specs. Your center pivots should move freely and not bind. Lastly, build the front end carefully, take your time with it. Typically this goes with any 1/12 front end. It took me well over a couple hours building my retro-fitted 12R5 front end on my Db12RR. Just make sure your titanium rods are STRAIGHT as if they are skewed, or slightly angled if can cause your caster to be off I believe if I recall right. Best of luck!

Thanks for all the Tips, as with most things ive got a lot of reading and research to do. most recently ive been running a custom Exotek RC18b setup for carpet oval. Its quite the screamer, It will be nice going to something "less complicated" drivetrain at least.

I like to drive a car that is way faster than the track is, so you can always get that faster lap or streak that is on the edge that sometimes you forget to breath.

Angled tie rods will affect ackerman settings, which determines the difference in steering angle between the front tires. Zero ackerman means both tires turn the same amount, whereas adding ackerman means the inside tire turns more than the outside tire.

Look on Associated site they have some dialed setups. dump the purples and go to lilacs or softer if that doesnt work go to angled servo setup.
Smart ass! I was thinkin about the softer front tires.

Don't be afraid to dope the fronts,3/4 is common with blacks.
Where is your battery? foward or back. We all run it back. Way more consistant.

Give more info on your setup!!!
Battery is in the back. I built the car as per the instructions as far as set up goes, with the exceptions listed in my earlier post. What do ya think about the orange rears. I'm not a big fan of how the yellow rears chunk up.

I don't have a lot of experience with this car, but I've found that orange rears tend to lose grip after 5-6 minutes. Up to the point where the rear grip goes away, the car is DIALED - after that, you'd better be prepared to hang on for those last few laps.

Does anyone have any good reccomendations for NE online shops that carry 12r Parts and Hop ups.

Trying to know what limitations are there so I can decide on gearing options.
Smallest spur you can fit to any 12th car is a 76T (64DP). Below that you can't get the gear in the diff!!

The largest pinion depends on how far forward you can get the motor. Limited in a CRC, miles of room in a BMI DB12RR. Not sure on a 12R5.

Gearing is dictated by the motor. If you have a 17.5, then it's a 76 in order to get the ratio you need. A 13.5 will need an 80 or 84T, and 10.5 or above you can use an 88T or 96T. Look to the ratio you want to run and the tyres sizes you want to use before deciding on a range of pinions.

Your spur and pinion sizes will depend on the motor first, the tyre size second and the room in the pod third. HTH

I have a 72 on my CRC GenXL. I don't know if I could go smaller as I haven't tried but I do know for sure that 76 isn't the smallest.

I've got a 72 on my R5.1 right now. Depending on what setting I'm using in the speedo really effects my spur choice.

thanks for the info guys.

Got some stuff coming for the RC12r5.1 and hope to have a better showing at the next race on the 6th.

I will say, of the AE cars I have owned, from the TC3s back when they were popular to a variety of B4s and T4s and an RC8 & RC8T, this one is fast becoming my favorite AE vehicle I have owned.

just trim the tab off the edge of the servo connector and will be fine
