The Copper Battery Tray weight for the NT1, what performace gains/impacts does this have on the car?
What is your ranking for best .12 motors on the market today for Short & Long Tracks. Money no option and or best bang for the buck.
Thanks for all your input and looks like I know where I am buying my motors from, from now on!
The brass battery tray allows you to lighten your car with things like Ti Pivot balls, light weight drivetrain, etc... and lower your CG while making the required 1725 grams for competition.
I noticed on my RRR that the car was easier to drive after I made these changes. Laptimes were faster too.
I would say for a large track the MMRBR3 is tough to beat. It has good bottom end, and seems to have a 3rd gear down the backstretch. It is also good on fuel consumption.
The MM Red Dot, and the MM+12 are also a great short track engines. They both have good bottom end. With the right pipe they are good for big tracks too. The same goes for the R3, with a pipe like the RB2611 the engine has gobs of torque. I usually use the RB 2604 for the larger tracks. Sometime the Novarossi 2630.
