You can run the same FDR in the B5 as you do in your B4.

On your B4:
FDR = (spur / pinion) x Internal Trans Ratio
FDR = (69/34) x 2.6
FDR = 5.28

On your new B5 (RM or MM):
FDR = (spur / pinion) x Internal Trans Ratio
5.28 = (81 / Pinion) x 2.6
5.28/2.6 = 81/pinion
2.03 = 81/pinion
pinion(2.03) = 81
pinion = 40 tooth

Well, you're going to need a smaller spur gear than what comes with the kit! I don't recall if the existing spur gears fit...

I suppose wherever you live heat may be a problem. Up here it's 40-50* at our indoor track and you can run a properly geared car for the whole pack and have it only warm.

Default Gearing

The kit comes with two spur gears (81 and 72). This way stock and modified can achieve proper gearing.

The magic bit is highlighted. A properly geared motor doesn't overheat.

I was referring to the comment you made about the car feeling "soft" due to heat, not the pack. I was saying no, it's not heat. But really, it's not even an important issue anyway, compared to WHEN do I get my B5!?!?

Why would AE not center the motor?

<insert speculation> Because centering the motor would probably introduce a tiny bit of unbalance to the car considering the weight of the motor plate and spur assembly.

That could suggest brushed motors were actually not balanced left to right.
All very interesting.

Still looking forward to seeing and feeling this kit in person.

The motor looks more "centered" on the B5M than the Centro. I added the Avid centering kit onto my centro because it was more balanced on the scales. I believe someone else on the centro thread posted their numbers.

Default RM vs MM

As far as witch is faster, it seems at or local tracks mid is slowly catching on..they do seem to be faster mid corner.
Our fastest drivers are all runnin mid motors now but our stock class is still dominated by rear motor...With more time i think mid WILL be the way to go...top cars at our track are Centro,KYO,Losi,shuey..nice mix on brands here and not one car dominates over another...The fastest cars are the new out of box types with fresh plastic

Had to pop in and say that this buggy looks fantastic! My only wish is that a couple more parts could be swapped over from the B4.. All my pretty aluminum..

Are the battery thumbscrews the same on the new B5 as the old B4? Or were they 'outdated' in the whole switch to Metric? I guess they come with the 'Team Kit' at least.. I will just miss my red ones..
