yellow rears and magenta fronts go good on most carpet tracks. in really high bite conditions its a good idea to glue the outside edge of all four tires. there are so many good combos. it is also about how you want your car to drive (agressive, easy to drive etc)

Around here it's yellow rears and fronts to get the bite you need. Double pinks, magenta's, or purple.

Pink rears don't seem to chunk as easily but they're a little slower. If you're running at a track that has a ton of traction or tends to pick up crud on the tires (tracks that run TQ8) black fronts will help stop the build up.

All the boxes I own has to large compartments for 2 small springs.

A pair of springs on a screw with a piece of masking tape showing what coil thickness they are.

on carpet, yelow rear and lilac fronts. high or low bite. i have been successfull with gray rears, but they get a little squirly at 7min.

7 day pill holders re your friend for all your 1/12th all parts needs. they have some with locking caps to keep parts from spilling out.

2 seperate classes is not the awnser at the club level. The more racers per class the better. We shouldn't thin out the class further. Isn't one of the reasons pan cars are coming back because there is only one class and one set of rules for better racing. It seems for WGT and 1/12th everyone only has one class for each:17.5, 4cell.

If we have to run lipo why not bring back Mod. Any motor, Any battery. 2 stock classes and a mod is too much, but I still think there should only be one class unless you really have alot of racers showing up.

Though I think A123 makes Lithium ION batteries in smaller sizes now. 2 cell is a little hotter than 4 cell nihm but not much. Maybe we can jump to those. I'm thinking about getting a little LiIon 2cell battery for my nitrobuggy so that I won't have to run a voltage regulator.(I have to run a Castle Creations reg to get my lipo output down to 6.9 volts for my radio/servos.)

Lets just stay with Nihm a little longer until the tech gets worked out so that everyone can run the same battery/motor like stock was intended.

There is an easy solution to this problem. Set a minimum weight on these lipo cars and enforce it at your local club. 740 grams.

Now everyone can run togather and be one big happy family.:sweat:

+1 for yellow rears and lilca fronts. I have also run pink, double pink and magenta fronts on lower bite tracks.

What length sensor wire are y'all using in 12th? I need to get a few from TQ, but theres like 15 different lengths!:weird:

I'm sure it makes a small difference so I will mention I am running a sphere in a 12R5 on the LH side.

Go to the local pharmacy and get a 7 day pill organizer. You can seperate out each spring rate. Works great.

Bead orginizers from the arts and crafts stores work well. However, given that you really only use .018's and .020's, and on a RARE occasion .022's, and that these springs tend to lose tension as they age and cost less than 2 bucks a pair, I wouldn't bother keeping old springs. I'd rather spend 20 bucks and carry 10 pairs of new springs and swap them out for fresh ones as needed.

Use a 150mm or longer depending on how you route it. I just put one in my 12r5 with a Sphere on the left.

The ESC is mounted on the "drivers side", same as the motor. The sensor input is on the far left side of the chassis. Sounds like 125-150 should work.

110 works good on a gen x. 125 should be a guarenteed fit but may have a little too much slack. 150 is probably too much

I've been using A123, (the smaller 1100mah cells) cells in a 2s2p configuration and loving them. Very light, geat punch and thay will last the full 8mins if your geared correctly.:nod:

If you have one handy would you do me a favor and let me know how long the 110 or 125 or 150 is from tip to tip including the connectors? I could measure the distance I need with some wire, I just need to know "where" the mm measurements are being taken on the sensor wire, know what I mean Vern?
