With my 10.5 (around 4200KV) bashing, im getting a solid 25-30 mins, I can get 50 mins if im not so aggressive with the gas, and pulling wheelie's, all of that stuff......

Ah poop, I was at my track today and found out that you can only use hard-cased lipos for racing and must have a liposack too. This means that I have only 2 options, right? Trakpower and Neu car lipo? Should I consider any other lipos? What about li-ion? I was thinking of a 2s1p a123 pack, but don't know if the voltage will be enough. I use about 120mAh a minute, so about 1000mAh for a 5min race; I think 2300mAh(a123) would cut it. Opinions/Suggestions?

Thanks!:mdr:

Do TrakPower man

There awesome!

Or cheat, and put some good cells in a hard case lol

Lot's of great cell's being deemed unusable because of the hard case rules. I wonder how long before someone releases some kind of universal or size specific aftermarket hard case?

If your track is following the new ROAR rules make sure you read this before purchasing. Also, the packs must be listed on a ROAR approved list. I dont think thi is available yet. I have to imagine that the trackpowers will be submitted and be listed.

Also pay attention to the sie limits!!

Read this for all of the info:

I'm still new to LiPos but if the 2s trackpower can rip my rustler's diff in a few wheelies with a plan MM7700kv system then i'd say thay have a LOT of power!

Dude, I hate rules! This means that the 25c trakpower lipos cannot be used because they are like 160mm long? This sucks big time! It makes me not want to race.

Bye:no:

The TrakPower lipos are not that big man

I use them in my touring car, theres the same exact size as a 6 cell nimh pack....

I called flightpower a little while ago, and they have a bunch of trakpower lipos ready to ship to ROAR for testing(a manufacture who wants ROAR to approve their product has to send them a certain number for testing). All their in-house testing passed the ROAR specifications. So, trakpowers are on their way to being ROAR approved!!!!!!!!!!!

I feel a little batter now.....

Bye:mdr:

They will be approved soon...... I see no reason why orion lipos would, and TP wont..

James is that with the stock strap or the optinal one ?. Thank's

Hey Mike, I use the stock strap and put some small al spacers under the posts. They look to be about 10mm tall, I also have a piece of velcro under the batt to keep it in place. With the spavers the top hole in the post is in jst the right place to keep it all tied down tight. The battery does get close to the spur, so I just taped a think piece of sheet steel to the pack in case it gets moved towards the spur. Very happy with these cells, I think that they are maxamp's best.

Thank's james mike said the same thing today about these cells.

acually, their not quite as tall. my trackpower fits a little looser in the battery tray than my 6 cell packs do.
