I'm wanting to drive my 1/12th with lipo next winter but here it come's.
Is it possible to drive 8th minutes with a 10.5 or 6.5 brushless engine with a single cell lipo?
Is there any need to have a receiver pack or something what ar the best cells now....

greetings

Either a receiver pack or power booster will always be needed at this time. It is not an issue with run time. It is a problem with the decreased voltage of the lipo pack. At 4.2 volts, it is a problem to run all the equipment. That power has to operate a servo, receiver and a speed controller. Servos are rated at 5 or 6 volts I think. If it does not get the voltage it needs, it will act strange and sometimes act very slow moving.
In addition, the speed control also needs that extra hit in order to run strong the whole run through. If you do not use a booster or receiver pack, the car will run good for about the first 1.5 minutes and then drastically slow down.
This holds true even with a 13.5 motor.

From what I have been told (I haven't done it myself), BUT a very reliable source said he raced 1/12th and 1/10th WGT last weekend and after racing 8mins in 12th scale and 6 min's in WGT. He had 3200 mah still left in the battery after the runs. So I would stick my head out and say yeah it can be done. Of course this was with a TQ booster installed.

8 minutes is no problem. You will definitely need a booster or receiver pack.

As for the best packs, probably SMC. There are a few others just now coming out but I don't know if anyone but team drivers have done a real back to back test.

And will the 1 cell lipo with a 4.5 motor have the same speed and laptimes ass a 4 cell 6.5 configuration?
Or what motor will have this kind of lap times.
Does anyone have a picture of a TQ booster or an Asso 12R5 with receiver pack installed because I think there isn't much room for.

Good question, the IIC Vegas Race Sept 7-13 will give us the answer regarding mod motors and 1s LiPo's for pan cars.

The easiest placement for the Novak Booster is directly on top of the servo.The weight is only about 7-grams (1-lead square) and is almost in the center of the chassis, thus unlikely to cause any handling issues.

Runtime on 1s LiPo with mod shouldn't be an issue. Below are used mAh from 1s LiPo in my cars:

For 17.5 1/12 LiPo racing - 8minutes = 2200mAh
For 13.5 1/12 LiPo racing - 8minutes = 2800mAh

For 13.5 WGT LiPo racing - 6minutes = 3000mAh

Here is a pic of the TQ booster in my 1/12 car, its the small white thing right next to the receiver. As mentioned runtime shoud'nt be any issue, but your lap times will most likely drop off some. It only stands to reason that your running the car on less voltage(3.7 vs 4.8) your going to be a touch slower. How much slower will be a function of your rollout and track size/layout.

I can't imagine hardcore 1/12th racers trading in their Tekins, LRPs, and KOs for a Novak Havok.

SMC 40C+ 4900mah Hard Case with inboard Connector
& if don't want to use receiver battery ,
can choice Novak Smart boost 3.3-4.2V up to 6V 3A .

Are the Cmax lipo's as fast as the normal SMC lipo's????

The CMax batteries, in theory, will have a greater potential.

Corsa57

what do you mean with more potential?

For spec racers (17.5, 13.5 etc.) that's true but mod is a whole different story.
