Wow who pushed rewind replay on this thread again? Back to batteries. Arguing about mah and c rating. If I remember the why can't I run this body argument comes next then the can we run a 21.5 argument after that. I guess its true. everything is circular an destined to end up right back where it started.

It's not the quitting... it's the spending more money to *think* they will go faster. When they've finally wasted enough money and still don't go any faster, THAT'S when they quit.
You can inform them all you want. They won't believe you until they've wasted the money. Follow the rule and people can cross batteries off the list of things to worry about and waste money on.

Is this why your MIA
We can make a 40 mile ruel
And spot ya a lap or 2 if that will get you back on the track

Why is their so much hostility in this thred ,i thought this class was sapose to be all about the fun. Let people ask their questions (even if they've been asked before) . If you dont want to answer them (again) dont .This thred always turns into the same couple guys crying around about people asking questions about the rules. Find me another form of racing where the rules arn't questioned, bet ya cant find one.

For anyone interested, I was in the middle of testing battery packs as this topic came up once again. I only have 5000 and 4000 mAh packs to play with. I used a Checkpoint 1030 and Duratrax Ice chargers set to a 10 amp discharge and recorded the average voltage at 600 seconds. I figure a 10 amp discharge at 10 minutes will be a close simulation of what we do in VTA minus the peak draws of hard acceleration.
My best 4000 mAh pack = 7.722V
My worst 5000 mAh pack = 7.813V
My best 5000 mAh pack = 7.901V
That difference of 1 or 2 tenths of a volt doesn't seem like much but I like to think of it the same as tenths of a second. Factor in that this is also a multiplier of the C rating and there is a real advantage to the higher mAh pack even if it is a small one. The difference between a 3800 and a 6500 is going to be much bigger. Maybe .5V. That would make the 3800 totally obsolete. At least with the 5000 mAh cap, the guy running a 3800 could still feel competitive as long as he realizes he has to be better than the "next guy" at suspension setup and driving in order to win.

Edit: I'm sorry I think I gave you a serious answer when you were probably asking a rhetorical question.

If you already own a viper esc, it may be possible to use it. Some local clubs or track owners allow deviations from the national rules. The club or venue you plan to primarily race at may allow it, (if you agree to run it in a nonboosted "blinky" mode). You wouldn't be legal at larger races, but at least you could race locally. Ask the places you plan to race at what their rules are regarding escs. They might allow it, or allow a grace period of some lenght where you can use it, but eventually you have to get a legal esc.

since I am new to RC and I was going to purchase a new one for my SC10 I was going to swap it over when I got everything for the VTA. it seems like it would be easier to just get the club kit with motor and leave the RTR esc in the SC10. Thanks for your help. I want to be able to race anywhere i go.
