I used to charge mine every run but my pack was only 150 mAh.
Thanks!

Just wanted to post an update on how the testing with the SMC 1C Lipo has been going.

At first I struggled with a lil more fall off towards the end of a run than I would have liked but have really figured some stuff out and have gotten the fall off down to what we see in 17.5/4-cell. So far what has worked the best for me is this setup, which equates to stock (17.5/4-cell) speeds.

Tekin RS with two capacitors
13.5 Motor Geared 45/76 with 1.72" tires
Hotwire setup timing at 100%, Sensored only mode
Currently running a Much More 200mah 7.4v lipo receiver pack
Also running the "red" wire from the speedo into the reciever

Speeds are really equel to stock. Punch, straightaway, everything. Driveability is great. Laptimes are identical to the car that just won 17.5/4 Cell at Vegas. Both cars hotlapped tonite at 10.1

If anyone has any quetsions feel free to ask I'll try to help as much as I can.

-Donny Lia

Edited: Forgot to add that I am running the car at 815g race ready. I believe the weight rule will have to be lowered a lil with li-po as there is just not enough space to add weight in these cars and its really unnecessary.
Looks great! Are you worried about running the electronics at 7.4 volts? It looks like your running a JR3650/3550 servo. That's what I run and was wondering how it will last with the extra voltage. Some say yay, some say nay.

You could try running this as a Rx pack. It may last two heats. The good thing is this pack has a built-in cut-off so no worries!! You'd also have to change the connector to fit your Rx. Just a thought,

The problem with cutoffs is that they have the habit of shutting off at the most inconvenient of times (end of the straight in mod). Bad things can happen so it's probably better to ruin a cheap LiPo rather than a chassis and body.

With the testing that I did on single cell the newer Spektrum stuff and the new KO stuff will run fine all the way until the pack completely dumps. No receiver pack required except for maybe mod. I did find that I need a voltage booster for the transponder (Novak makes one).

For me, LiPo receiver packs are a $20 solution for a $5 problem. NiMh receiver cells are only about $1 each...

Yep, cutting off a Rx pack down a straight would SUCK!! Didn't think of that!! Glad to hear the pack can run the ESC and servo in everything but mod.....since I probably won't be running mod.

EA, thanks for the info on the trinity based motors. I haven't had time to do a ton of testing, it just woke it up big time when I turned the timing up a notch. Someone running the 17.5 trinity in touring couldn't get it running without going up in timing either so I gave it a try and it seemed to work.

Fred and Cia:

I don't know if your gonna want to not run a reciever pack with 1c lipo. From what I've seen while it does "run" the servo gets a lil lazy under WOT. Just easier to do the ol 5$ receiver pack trick.

Nevermind, it was answered a few posts back.. hah..

Is it worth it to get the 1/3AA 300mAh, or just stick to the 150/120 1/3AAA's?

Any word on a production/release date? I need to know when to expect it. We are hoping to use it for 1/10th scale oval racing.

I hope not. Seems to me everything I get that is made in China... either doesnt work or doesnt last very long. Just like the 4600's I used to have.
CHINA SUCKS ! We should all be carefull to NOT purchace products made there. That also seems to be an issue with the economy here.

With reputation of the existing SMC lipo batteries, I really doubt this one will have any problems if the cells are coming from the same place.

I ran the same SMC LiPo all summer in sedan and it's still good. The single cell pack should be from the same supplier so it's going to be fine. None of the RC LiPo's that I know of are made in the US. Kokam does make cells in the states for the military though.

Any news as to a release date yet? I am pretty sure it's been asked before, it would be nice to know where we're at.

As for the cells they'll be good if Danny is associated with it in any way, and he is.

It's been a little quiet. Anyone done any testing lately?
