There is a conversion kit from the DB12R to the DB12RR which can be found here:

http://www.bmiracing.com/webstore/ca...612a65c5798a50

As for the differences...well I came along after the original DB12 so I can not say what the difference between that and the DB12R are but here is the DB12R to DB12RR:

- Wider rear pod and recentered axle for brushless motor centering.
- Shorter diff side hub to recenter the axle.
- Longer rear pod to enhance rear suspension handling.
- Upper pod shock mount position moved over the center pivot.
- Chassis shortened to adjust for the longer pod and keep wheel base the same.
- Rear flex plates lengthened for better handling.
- Multiple shock mount positions added.
- Servo mount holes slotted.

I think that's pretty much it.

I assembled half of the car now. OK I didnīt follow the instructions completely, I did begin with the rear as I wanted to see how the pod and flexplates are working. Front suspension, tubes and center shock will follow tomorrow. Regarding the graphite parts I just removed the sharp edges but didnīt seal the chassis this time.
Iīm really impressed with the quality of the DB12RR so far. Especially the graphite parts are much stiffer than you would find with some other brands. Also very nice aluminium parts and anodizing.
Just one small "flaw" I did find until now is the flathead screws are not completely flat/even with the chassis. I did find this with most other cars in the past also, I know this has to do with variance of thickness of flathead screws.
Itīs just the problem if you live in Europe you canīt get those 4-40 screws in numbers that easy so you could select the thinnest for perfect flatness. I know the aluminium screws are a little thinner usually but I have to say I donīt trust in them regarding strength.

One question regarding the flexplate pivot balls. After assembling I noticed these are working very smooth and I canīt detect any play. One side is extremly free working and the other side just is a little less free and very slightly binding but still smooth and falling down. I think this will work out perfectly after some runs.
The question is do you really need the setscrews for adjusting play? I think if you donīt use the setscrews itīs just much easier checking out if the pivot balls still are firmly fixed to the chassis.
Regarding the tubes I just have some CRC medium lube (white cap) and 20000 Wt siliconoil here. I think the 20000 maybe is a little too much, whatīs about the CRC lube?

You can update the R to the RR for $99.99 and we have the upgrade kits in stock.

Here is what the kit consists of:

The chassis
lower pod plate
1 pc crossbrace
offset hub
top pod plate
flex plates
pod cross tube
damper tube pistons

As you can see this kit is a steal. I cut the prices on all the parts so that it wouldnt take a ton of money to have the latest and greatest.

They strip the origional color and replate the parts to the new color. Deluxe does a great job.

Thanks.

Well My first time out with the car on asphalt in months last night. I had updated the car with the new brushless pod but did'nt have the $ to do the whole upgrade kit so I'm still using the 12r chassis. This makes the car about 1/4" longer so I was'nt 100% sure about the handleing. The first couple of rounds I was fighting it a bit, the traction was low to med and with only three 1/12 and all the TC's runing rubber it did'nt get any better as the night wore on. But after a couple of changes the car was butter in the main. My top5, top10, and top20 laps were all within a tenth which is just the consistancy I want to see.

As expected the car is a bit pushy in this configuration and its a bit slower thru a tight corner than I'd like. But the offset is also true that its very stable and very easy to drive. When I can afford it I'll get the new chassis and get her back to flying thru the corners. Still really fun to drive just as it is.

Learned something new tonight with the car.
This weeks layout has a couple of chicanes I was trying to get the car to wiggle thru. I actually went softer from #4 to #2 shurlube in the rear, long flex links, and it worked. Seems like the car can now switch direction quicker (less pack in the tubes) but still has plenty of forward traction(long flex links). Everyone commented on how smooth the car looked. Gonna see what happens with lighter lube on the kingpins next week.

Has anyone put the CRC Pro strut long arm front end on their DB12RR? If so did you like it better and what are the parts and part numbers I need to put the crc long arm front end on?

Congrat's to Greg "ShowTime" and Mike Sr. for putting their 12RR's in the show in the last leg of the North East Grand Slam. There was some tough competetion there this weekend.
