Be sure to round off the edges of the chassis where the tape passes over it. You might want to use a piece of double sided or servo tape under the pack for a bit of extra security. Again if you need flex plates PM Jason, he may have some or know who does even if they're not on the site.

I am sure Jason has what you need, and if not, will figure out how to help you. He has been off the boards as of late due to the birth of his son.
I picked up a DB12R a while back and I have finally been able to get it running recently. So far things have been okay but as I get more and more into tuning this thing for my track, I'm beginning to find some some problems.
First of all, I am seriously behind on the learning curve for all things BMI and have just read back through many pages dating all the way to early '08 between the development of the single "R" and the double "R".
First problem: I am using 1s lipo with the o-ring to hold it in place. The lipo is pushed all the towards the back with the electronics holding it in front. The problem was that the rear end was not so free and seem to bind a bit in its movement. I notice its because the lipo case is pushing against the "hockey sticks" that is causing this binding. I need to move the battery more forward and find some way to hold it in the rear to keep it from binding on the suspension links.
Second problem: The chassis I have uses the two piece battery brace/ body mount holder. I notice that there is some flexing between the two sides. Other cars like CRC, Speedmerchant and etc. don't have this problem because of the tweak plate that braces the chassis in the rear. Is it okay to have this flexing?
It looks like the solution, after looking back on this thread, is the one piece battery brace. I found two different ones. One with the extra hole and the other without the extra hole. My chassis doesn't have the extra hole but I can probably drill the extra hole if need be. Just wondering if I need or want the brace with the extra hole or not. What are the advantages to mounting the suspension links on the extra hole?
Also, BMI doesn't show suspension links available on their website. Is it just not listed and maybe they still have left over stock to sell? I'm looking for the super thin ones.
Any help would be appreciated.
Thanks.

Just FYI if anyone is interested I may be selling a BMI DB12RR w/ tons of spare suspension bits, and an R5 front end. Just got essentially 2 new V-Dezign cars I am going to be running coming up and the BMI isnt going to be used much. PM me if interested. Not sure I am going to sell it yet as I love the car, just dont need it though.

The four hole chassis fits my KO 949Ics servo perfectly.

All 1/12 cars are made to run with mini sized servos. The cars are not designed to run standard sized servos for 1/10 cars. The most popular of the mini sized servo is the Futaba. Next is the KO and JR also makes one that is suitable.

Hey guys. I have the bmi 12rr. with lipo chassis.
was wondering if anyone might have a great asphalt mod ( yes mod and on asphalt) set up .
I will probably starting with a 10.5 then going down as my skills increase.
I normally run 17.5 boost on carpet.
Our club decided to have some fun this summer and run mod for us faster guys that are looking for a challenge. I have run 19 and 13.5 in the past but this will be a fun experience.
So any help would be great.
thanks in advance.

Anyone still running this car?
Looking at a deal for one.. OR a CRC GENX XL - the BMI comes with lots of spares.. the XL none.. but in my area no one runs BMI..
Is this car easy to run and setup? I know its moved onto the copperhead.. but is that because there was issues with this car?
