Thanks for any help!

I ran a spx in practice at a Large event this past weekend (NWIC) on carpet, 60 x 100 track, same battery, 5 cell rec pack, sp v3 13.5, sweet spot for RO was 71 mm.
The real trick was to use profile 7, not 8.....:weird:

If you're runnin' against Tekins........enjoy the scenery........:lol: tail lights, theirs

I use the Futaba but both are about equal. It will come down to Chevy vs Ford debates if you ask around for opinions.

I don't know the Airtronics but the Futaba S9650 is very good. Don't forget the JR Z3650 either, I'm running one at the moment and I think it's even faster than the Futaba.

Wire thickness for my ESC?
 
I have just purchased a slightly used LRP SXX Comp ESC, but there are no motor wires on it.
What thickness should i use?
14AWG or 16AWG?

I run a LRP Vector X12 5,5T motor and 1s Lipo.
Is 16AWG thick enough?


And are there anyone who will post a picture of there car with a RX battery?
I need some ideas where to place it on my Associated 12R5.1

16ga is fine. I mounted my Rx battery on top of the servo, just no pictures. Here's the link to the one I use; http://www.amainhobbies.com/product_...ack-74V-220mAh
Nice size, light weight, and cheap priced.

Its been awhile since I've heard much talk of people running unregulated receiver packs. For those who have, how are the servos holding up? I'm running a Futaba and just haven't heard much about it.

12th scale wire ??
 
3 Attachment(s)
I have a couple rolls of Race Prep wire from back in the early 90's that have never been used ... it seems to be too thin for 14 gauge, and I had a tip that the 12 scale guys may run 16-18 gauge wire if it is flexible, which this is. There are a little over 9' of both both orange and black (18' total), and I also have about 2' of good quality battery braid as well .. drop me a note if you have a use for them.

Servo Specs?
 
I'm new to 1/12th scale pan cars, and I have a question regarding servo needs for this class. I did a search on this thread on servo's, but all I found was REALLY old messages on the subject.
The manual says that a "micro" servo is recommended, but I'm a little leery of what each manufacturer might consider "Micro". I'm looking at a Hitec HSG - 5084MG Digital servo with these specs -

Motor type: 3 Pole
Bearing type: Metal Gear
Speed: 0.07 @ 6v
Torque: 26oz @ 6v, or 1.9kg.cm
size: 29mm x 13mm x 30mm (34mm mount points-which appear to fit the left side)

Is that enough torque? This sure is a small little burger—I"m used to 1/10th scale servo's. Any help is much appreciated.

...Ron

Do yourself a favor and get a Futaba 9560.

Ron,


Hitec HSG - 5084MG, will fit in a 12th scale, the sizing is a little smaller than JR Z3650

Depending on what car you are running JR Z3650 is my choice.

Spend a little more and get JR Z3650.

Found this being metal gear also faster over the Futaba S9650, this is just personal preference however.

It don't fit in the RC12 due to the servo being mounted to the deck, can be done via servo tape just make sure you warm up the tape before hand to get a good seal.

CRC, Xray and Serpent 120 all have servo post like TC's.. so can run something smaller.


Hope this helps

Servo suggestion
 
Thanks Me_MrTyson,

I'll look into the JR servo.

I have a XRay XII Link, with the Novak Havoc 1S ESC/Novak 13.5SS Pro brushless motor, Spektrum SR3500 micro receiver, and a 1S lipo. This is looking to be tons of fun!!!
