Default To regulate, Or not?

Now this has probably been discussed at length before, and I've read bits and pieces here and there.

My Question: I'm planning on running Lipo reciever packs in my off road cars, both are running spektrum SR3100 micro DSM2 recievers with ACE DS1015 & DS1313 servos, should I install regulators into these cars?

Also, as a regulator regulates the power to the servo's, will they improve runtime of the pack, as they reduce the power coming from the pack?

My present 1600mah nimh hump pack reaches nearly 8 volts on my charger at present, and I've had no trouble with it, so I'm wondering if a regulator is really required.

I've read some say yes to regulate, and others to say dont worry, looking for a definitive answer (if there is one)

I run Trinity lipo 2300 receiver packs, with a Losi regulator. If you dont use the regulator you'll have problems with destroying your sevos with to much voltage. I think 7.4 volts is to much.

I've heard experienced people giving answers both ways about 50/50, so I'll be interested in seeing what the opinion is here.

i was running airplane thunder power lipos years ago. i new of no regulator at that time since for over a year i ran with out one. I was running jr 590 and jr 650 servos and jy radio and receiver. i would go through a set of steering and throttle servos over a race season. Not bad being they were not the top of the line servos. I sent them to JR and they always sent me new servos, it never damaged my receiver. I would reccomend to use a regulator I do not know the effect on a top of the line $100+ servos and I wouldnt want to burn through some of those.LOL In feb. JR is going to release the HV servos that do not need a regulator and if you use a spektrum receiver they can both handle the voltage.

I use to run a regulator with my lipo, I have had the reg go out 3 diff times 1 of the times was a run away! Had the reg mounted out side the box so it would not get over heated! Now i run with out a reg, just straight lipo and have not had any problems with, doing this has increased the speed and torque of the servos

How long has it been since you have not been running a reg?

I guess I would prefer a $100 servo go out than have my MP9 or ST-RR runaway and destroy.

I have had 3 regulators go out in the last year. 2 run aways and 1 cost me a top 5 finish in a big race during the Amain. Had researched this to death and i decided to go back to NIMH. I run Futaba gear and they said I would have to regulate with the brushless servos. ALOT of Pro's are not running the lipo's due to the regultors failing during big races. Hopefully all the radio gear will eventually be capable of handling the lipos.

To me, the lipos just isnt worth it. I mean, whats the big deal of having to charge the pack once or twice during a race day???? I can easily get a hr. run time on a NIMH.

That being said, I know BlackBart, and he hasn't had any trouble since he took out his reg. Hopefully he won't, time will tell. I have just had to many issues running the lipo/reg, so I just say hell with it.

So it certainly sounds to me that the Regulators are a prob. I've already got the lipo's coming, so I'll bite the bullet and run them without a reg and see what happens.

Keep the responses coming, very interesting to hear everyone's experiences

I know my bud Ricky is securing his regulstor and putting some silicone on the wire where they meet the board, His has worked, but then again, its just one more thing to worry about.

+1 But other than that one time, I have had zero trouble out of my lipo/reg setup and I am running some of the cheapest lipo and reg out there. I do buy a new reg about once a year, but heck I do everything else too.

I actually had more trouble with high quality Nimh batteries. I had a good Orion pack all but burn up my car once. The battery shorted out internally and she was hottt before I could finally sling it out. I also had another one break a wire in the pack, with the car wide open. Failsafes don't work when there is no juice. Lucky for me a quick thinking turn marshall knew what to do. I went through 3-4 nimh packs my first year. -1 going back to Nimh.

I've been running lipo with a regulator for almost 2 full race seasons and never had a problem with the regulator. I use Novak regulators.
