Here is my Copperhead 10. The only change i made for this past weekend was that i went to an AE green center spring due to the lower traction. The car worked really well.

Actually, i made 1 more change. I ran the longest shock position on the battery hold down with the plate spun around 180 degrees. This is 1/8 inch shorter than when it is in standard front offset position.

I was looking at one of the newer guys BMI this past weekend and noticed it did not have any tweak adjustment screws. Is this normal? I've never run a BMI and always thought that you should have some way to adjust the tweak of the car. He was having a difficult time getting it up to speed but I'm pretty sure it was the full size tires keeping it from driving better.

jason said it doen't tweak

The last few years 1/12th drivers have been balancing their cars left to right so there is no need for a tweak adjustment. Then they just tighten the tweak screws or roll springs down until they just barely touch rather than using them for an actual tweak adjustment. Since the BMI uses a flex plate design which is held in place it doesn't need a tweak screw. Similarly the HB car which has an option to use a spacer on the front of the T-Plate instead of a pivot which would then not need a tweak screw.

Hey Chris, I would if I thought anyone else would. We can't even round up enough guys for 1/12Th lately. How about shooting me a pm next time you guys are coming down. I'm so desperate I bought a B4.

That is normal. There is no need for tweak adjustment on this car as it does not utilize front and rear pivots on the flex plates. We use precision machined spacer plates under the front of flex plates and all of the flex plates are matched sets to eliminate the need for tweak screws or any tweaking for that matter. We took the difficulty out of 1/12th. There are many things that can make a car work well or work poorly, I assure you that having tweak screws would not fix the problem your friend is having. There is going to be an issue in the setup somewhere. If you like, have him give a call to the shop and i can get him taken care of.

Hey Jason,

do you have to use a mini servo for the copperhead 12?? will a normal size servo fit?? if yes, am thinking of a Savox servo, one is 5KGs and 0.048s and the other is 10KGs and 0.07s, what do you think is better ??

cheers

We do use mini servos. I like the futaba 9602

I知 half way though putting Copperhead 12 together. This thing is soooo easy to build. I知 very happy with it so far. I知 not sure what to do with $1000 worth spare parts from DB12RR. Is it possible to use old flex plate pivot hosing used on new kit? I assume front end and diff assembly are identical apart from color?

HarryLeach

I can't say for certain since I didn't have a DB12RR, but I believe the major differences between the 12RR and Copperhead are the main chassis, lower pod plate and flex links.

That's a lot of spare parts...like 5 complete cars worth!

3 1/2 spare cars on top of parts as well
You should see my friends spare. He got almost twice as much.
Us two put together and we got more than 10 BMI 12th scale cars!
We don't have hobby shop carries BMI in Australia so $500-600 parts order is normal for us. And thanks to new kits my bank account is next to zero
