An RX pack or booster HAS to feed back into the ESC, to make the ESC circuitry work properly. My first week of 17.5/1S lipo in 1/12th, I hadn't gotten my booster yet, so I rigged up a 300mAh 2S RX pack and CC BEC. Work good, till the first heat, when the RX pack went dead. (I hadn't recharged it after 3 practice runs or so) The motor cogged so badly the car wouldn't hardly move. (Same thing will happen if you pull the red wire from the ESC out of the receiver plug.) Recharged the RX battery and all was good. RX pack and CC BEC were too much weight tho. Car was 790 grams, with a lightweight body. Went to the TQ Booster and a regular weight body and the car is 740 grams.

I see, so if you run a receiver pack, then you pull the red wire out of the speedo lead to the receiver? Or do you do that for both the receiver and a booster?

Read my post again. The motor will cog horribly if you pull the red wire out of the ESC receiver plug. The voltage from the RX pack or booster has to feed back into the ESC through that red wire, to make the ESC work properly.

If you run a booster and firmware V200, the switch is turned on on the ESC. There are 2 flavors of TQ booster, the new and the old. The old one just plugs in, the new one has an inline switch. If you have the old one, you have to unplug it or the battery to truly turn the car off. With the new one, it has its own switch and you just turn it on to run and off when your done.

It will send power to the speedo. However it won't help power the motor which is what I should have added to clarify my previous post.

If you're running 198 or better make sure to select the 1s check box and you will run with the swtich in the on position.

Dennis,

What kind of racing and motor are you looking at. You'd also be better off getting the V200 from Randy. The settings for 1S (3.7V and 3.0V lipo cut off) are accessed via Hotwire only.

Step up and step down convertors just aren't the same as raw available power such as what a rxr pack can supply.

At the IIC even the stock guys, the fast ones, used external rxr packs over boosters,

but if you have something working for you, go for it.
I placed 6th in stock at IIC with a Tekin/Booster combo, FWIW.

From what I gather at our local track, no one is running Rx packs... boosters all the way. The current gen LiPo's are more than strong enough and have enough capacity to support a Booster and not impact runtime.

And I dig the small Hobby City and TQ boosters more than the Novak... the Novak is too big, too heavy ,and I think too funky. When I just re did my BMI I was tempted to put the Novak back in play to try it again, but I used the Hobby City booster just cause its small and works.

Some pics of my newly re-done 12th.
