Servos and Rx run off 6v in TC. The BEC in your ESC converts the 7.4 to 6v.

As Clegg indicated, the BEC in the ESC regulates the voltage down to 6V in the TC case. The difference here is that you are providing 7.2V directly to the Rx, which doesn't have a BEC. Thus, the answer to your question is more than likely yes. Some servos and Rx are more tolerant to voltages above 6V than others. To be safe, you should use one.

A mate of mine just bought a bunch of these....
Anybody used these yet?

Where would i be able to get one cheaper? or is this the cheapest i will get it?

thanks
Alex

what voltage regulator would you recommend ?

I'm looking for a 1/12 scale. Got a offer on a CORALLY SP12M, but how is it with 1s Lipo? Looks like the chassi won't hold a 1s.
Don't want to go back to nimh again.

Should i get another car or is there some modification that works to make 1s fit?
Is it possible to get parts for it still? Had a quick look on ebay and not much parts for it for sale.

It's either 1/12 or WGT... Not sure what to get. :rolleyes:

You can put it on 1 side of the chasis:

I'm judging by your sig info that you're from Oz so this likely doesn't affect you, but it MAY be very significant to some racers here in the US and Canada.

As far as I can tell this battery is not currently on the ROAR approval list, and even if it were it would need the Trinity label on it as Trinity are the approved importer here. If your club doesn't rely on ROAR insurance it's a non-issue, but if your club DOES rely on that insurance this is one of those things with which compliance MUST be insisted upon. I don't know about your club, but ours doesn't have enough funds to re-build the Shrine should we manage to burn it down.

The current list of approved LiPo batteries is at http://www.roarracing.com/approvals/lipobattery.php

I can only identify three approved 1s batteries, the SMC 4000, the Fantom 5000 and the Thunder Power 5000. This isn't to say there isn't another one or two in there that aren't identified "single cell". This list is also likely to change between now and the end of the year as ROAR are allowing "open approval" of 1s until then.

hmmm
 

yeah i'm from OZ. we dont have a club that races 1/12th yet. Just a few of us are starting to get stuff together and trying to sort everything out. i am running 4 cell as OZ rules have no lipo class at all, let alone approved 1 cells. i thought the roar approved sticker on the battery would mean it had been through all the procedures with roar though.....

I will stick with 4 cell for a while anyway since i have 4 new packs. just looking towards the future. for the extra few dollars though i might get the SMC packs when i do go lipo. i like the way the have the ribs to fit in the battery slots.... not sure if intellect have this.

thanks

I thought few people ran SMC4900 pack at ICC.
Did ICC used different rules to ROAR?

I believe ROAR's website has not been updated with the current batteries. I ran the SMC 4900 packs with the internal bullet connector at the IIC and they ran very well.

To be honest you'd be better off finding a 12r5 used, I've seen these go for as litle as $100-$150. You might be able to get a brushless motor in an l3 but as its a t-bar car it will not support 1s lipo which most tracks are going to.


All of the older corally cars are t-bar cars which are not totally lipo friendly, You can put the lipo on one side with the electronics on the other but most are having to add a siqnificant amount of weight to balance the car, which defeates the weight savings of the lipo. I wont say not to get that car but you'd be farther ahead to buy a car that supports 1s lipo better.

Hi guys, after years of running NiCad's, then onto NiMh's, I am now going to go over to LiPo for my 1/12h car. I have a Robitronic Overloader (probably the worst name for a charger ever!) which says it does LiPo but what settings should I use for 1c LiPo? I have heard of LiPo packs catching fire or blowing up, so what precautions should I take? A LiPo bag?? I have also heard of people saying that the pack needs to be warmed up whilst charging, or others saying that you should keep them cool, so what's the deal there?? Many thanks for your help guys, just want to be sure about how to handle these new to me cells! Cheers, Chris.

I would NOT recommend warming 1 cell LiPos. I thought I would try it when I was at Vegas. I left one of my SMC 4900's on the control unit of my Soldering iron to get it a little warm. I pulled it off and temped it at 128*F at it's hottest point and it had puffed a noticeable amount. It reduced a little after it cooled, and never separated the case, but its now raised a bit in the center . . .

Try it at your own risk . . .

I dont think you are supposed to heat any LiPo... just asking for trouble.
