Thanks, glad the setup is working for you. What is the traction level like at your track? I've been really working on smoothing the car out lately and it just keeps getting faster. Seems that with the single cell any amount of "dig" in the front end of the car and it just kinda stops in the corner. Momentum is the name of the game now since we dont have the voltage to accelerate like we used to.

Our traction level is medium to medium/high. Your setup really smoothed the car out - turn-in, mid corner and exit. I've seen the difference now, with a car that "rolls" through the corner instead of a "dig" and accelerate type setup. I have been trying front-end and servo mounting variations to minimize the ackerman. Seems to really help the corner speed. To much wheel scrub is like dropping anchor.

Thanks for sharing your setup findings. I assume you running the CRC front end by stating in your setup that your running the long arms. So by running the 5 degree blocks and the firm .22 spring helps the car from digging into the corners? Makes sense to me. Can I ask, where are you running your antenna mount in the car (front/back)?

No running the associated front end with spacers between the arm and blocks. That really helps smooth the car out at the apex of the corner.
Also I'm running the antenna mount 1 hole forward from the rear.

Take the bottom of a castor block. Cut the top off and use it as a spacer.

This thread is dead. I think everyone tried out Showtime's setup. No more questions!

What "brand"of front springs are popular w/the 12rr?I seem to have issues with some of the larger dia. springs and seats hitting the rim.Is this an incorrect build on my part or do some rims just hit.I am running 4*caster and would think running more would make the prob worse.BSR and ellegi rims hit,gonna try some jaco prism or crc next.
Also What is the correct kingpin length?When assembled mine has no washers on the top,1 under the steering block,and none on the bottom.this gives me about .5mm droop race ready-it doesn't seem right to me -but I am new to the car and bought it used.It is the lipo version if that matters.I don't think it has the right kingpin in it-- but I may be wrong.

I use crc springs. I think I have 4 washers on top of the king pin. I use crc tires.

I have been running the BMI linear springs with the longer 1/10 king pins Jason sells. I usually shim them so they have just a touch of preload when the car is off the ground. Sometimes I will have to put an extra washer on top to keep the spring perch from hitting the rim. Relocating the sticker on the rim also helps to get more clearance. This is with the jaco prism/ Parma rim. You can also take a dremel and round the square corner off the bottom of the perch a little for more clearance.

Default servo

I am assembling my very first BMI car now.
Under what conditions do you use flat or angled servo?
With flat servo you need the longer ball stud - the manual says. Is this the same as you use with the shock on the antenna mount?
What happens if I place the antenna mount closer to the batteries?
best regards,
Zoltan

Jason - when you get a sec... check your email. I ordered some stuff last week, and got the wrong bits in the package.

Running the servo flat will have a more mellow forgiving feel and angled is more agressive. When running the flat servo you will need the medium ball studs like on the shock mount.

If you move the antenna mount closer to the batts it will increase rotation in the corner.
