Default 1/12 scale: voltage booster regulator or separate receiver battery pack

Hello folks,
Do you prefer to use a separate receiver battery or Voltage booster regulator.
The way I see it by having a regulator just adds another point of failure into the system, but in return adds convenient where you just plug in the main battery and go and not worry about having a separate receiver pack to charge or took a dump when you accidentally forgot to charge it.

On the other hand, having a separate receiver pack is more reliable and bullet proof and also the benefit of extra current overhead for power hungry servos. But the trade off is it's just adds another pack of battery to charge after a few runs, and if you don't keep a careful look out on the remaining charge it could take a dump on you by surprise during a race.

I fly model helicopters and I always choose to have the receiver battery over the bec or voltage regulator any day, for reliability sake. just the battery connected directly to the receiver, no switch or regulator in between.

But that's model aircraft, I'm more concern about it loosing control and coming down and hurting someone.
Since this is on a car I don't have to worry about this situation.

Default another option

or you can choose to run either an new edition LRP or SpeedPassion speedo that has a booster built in for 1cell racing......which eliminates the need for either a receiver pack or a separate booster. My SpeedPassion works just fine with neither.

I've been using the receiver pack in both my 1/12 and WGT for two years without any failure. The batteries were much cheaper than replacing my Tekin RSs.

Can't say the same about the booster I used (Novak).

An rx battery can also be a point of failure if you forget to charge it as I found out this weekend...I figured I could get at least 2 runs out of my 220mah RX pack but I couldn't. Each run was using up about 150mah of capacity.

Does that work well with the RS? I like how it just plugs in-line with the ESC without having to have extra wires running to the main battery.

well you have to solder 2 wires, one to the battery + and one to - on the esc

but for the money saved its worth the 5min extra job

Ah my mistake...It looked to me like it was coming off the ESC and didn't realize the pic only had 2 wires going in instead of 3.

If you want to run a booster and want to run the absolute best, get the RC Dynamics booster. Details at www.rcdynamics.co.uk. Not cheap, but worth every penny. I've run one now for nearly 2 years and I've never heard of a single failure or a single drop out. I'd use one of these over an RX pack any day for the convenience, and there is no drop in servo speed whatsoever.

An interesting note. At my local track there are only two drivers that use booster, one a Novak and the other uses the Hobbywing ESC all the rest use a battery pack.

The guy that uses the Novak is not one of the top performers but the one with the Hobbywing does pretty good. It seems that the steering is a bit slower with the Hobbywing but I'm not sure of the volt output. I do know that the nominal voltage from a LiFe is 6.6 volts and down to 6 when dumped which is certainly better than the 5 Volts of most boosters. Yes, it's one more thing to do but I do have a dedicated charger just for my two LiFe packs and it takes 10 minutes or less to charge. (Charger is one of the cheap $40 type which can also charge Lipo and NiMH).

I have used a booster since we started using lipos with no problems in both 1/12th and wgt.

I have tested back to back, many times with life pack & TQ booster.
same lap time, and feel no different.
