(3) Tires...I know it is very much standard front PURPLE rear GREY...but I am wonder, is PARMA front purple = Jaco front purple? Vise Versa...Parma rear grey = Jaco rear grey...? or what shores should I use for JACO.. (I already know about PARMA)
Thanks in advance.....

Scottrick - Great purchas on the Unity Tweak/set up. I've owned mine for 15+ years and it is still dead on. When I started racing again a few years back, I could never get to it, as it was being used. Now there are 2 new ones as well, and since the new ones have a better scale for degree's that what get used!
To the rest, I saw the post for the 13.5 being faster than stock motors. Our series is based on 19 turns, and we have 1 or 2 that have asked about the 4300 brushless. As I have one, I really think it is faster than a brushed 19 turn, but whats anyone's thought???

Just figured I would post some info here since it seems to be the most active 12th forum on the net.
At the Vegas race, I talked to Anderson from JR/Horizon about the 3550 servo that was discontinued. I explained to him that we thought it was a really good product for 12th stock, and were unhappy to see it go away.
Long story short.
Anderson e-mailed me this morning that they(Horizon) have decided to "reactivate" the 3550 servo.
Take care.-Bruce

I just went to the Horizon website and they still list the 3550 servo although it does say back ordered. I went ahead and placed an order for six (6) servos to let Horizon know that there is still interest in this servo. I think OD did the same. Now, since you opened this can of worms, you had better bug Anderson a couple of times a month about following through with the reintroduction of the JR 3550 servo.
Seriously, thanks for all of your support, Bruce. We racers really appreciate all that you do for the sport/hobby.
the 3650 is rated at .09 sec @6.0v. but can you use it without a seperate reciever pack. will it be slower running off the 4 cell pack? reason i ask is on mike dumas speedmerchant from vegas he does not run a reciever pack with this servo. thanx

CRC is about to revolutionize 12th scale building when it releases its new front end. if you search through rc.50.com youll find pics. No more black magic (my specialty-ho hum) to get a perfect front end everytime.
some highlights include super fast and easy camber adjust with pillow ball, fast caster adjustments and no more shims on the kingpins. YOu adjust spring tension (preload or no preload) with a hex driver. Very hard to build it wrong (ie. binding). Ride height adjustment will be enough to run a rim with felt on it to a full size uncut tire. Steering arm (spindle) is now outside of the rim.
Also-with the flip of a part-you can go from unheard of caster to the caster we run now as well as choosing between 0,5 and 10 deg mounts.

I've never run 1/12 scale and hate being the noob asking dumb ass questions, but... 

CRC front end
I also forgot to mention that it has a way of building it to its like the old skool front end (no reactive caster or adjustable upper arm). I forget how-but Frank told me about that feature at vegas.

JON hopefully i can help you here most of the stock racers and mod racers(dumas,mcmahone,dayger,prichard)have all gone back to spring cars for mod so their is really only two choices rev4.5 or crc knife as for reciever packs alot of people dont run them anymore due to the new cells having so much run time you really dont get into the lower voltage of a pack to make the servo got a littel nuts on you and as for bodies it still looks like the parma speed 8 is the stock body while the protoform speed12 is the mod choice ..
ray that front end is pretty bad a$$ hopefully it will be on my car before the holloween race

the BMI allows you to run a damper disc or damper tube setup. You get 2 upper pod plates (one for each). just make sure to understand that all the holes for the tube mounts are drilled to be tapped 4-40. i didn't know there were tubes designed to accommodate 4-40 cups. so jason is taking care of me and some 2-56 holes. the other nice thing about it is the cut on the bottom side of the chassis that recesses enough for tape so it isn't exposed as much (nor are the batteries).
great service.
