They are live right now, they do not look so slow...... I heard the 1c is going to be alot lower in cost..... Could we be seeing a great new class?

I heard the packs are so light that they are trying to stop them from flipping over.

Lower is a matter of comparison...

A 2400 2 cell LIPO from Orion is 35 bucks, and is still too fast w/ a 21.5 motor, and handles the time just fine.... Can't get much cheaper than that - and I hear the SMC SINGLE will be over 60

We've been playing with the 2400 packs at our local track - running them in a 17.5/LIPO Nastruck. They are QUICK, Make Time...run about 1 -2 tenths slower than the 3200 ORION did

Another class??

Let's run with what we have now.

Too many new classes thins out what small turnout of racers at tracks
now.

...I'm not donig another class - I'm just allowing the 2400's to run in our LIPO/17.5 TRUCK class. (with NO added weight) the lower weight might help offset some of the lower performance) and locally, we race for FUN...

I'd love to see (4) standard OVAL classes for the U.S. - and tracks use (3) of them based on the size and speed of the track

But, that will NEVER happen - so we do what we do to keep the racers we have as happy as possible and keep them COMING BACK.

i don't see anybody making a slower motor for 2C.... at least someone is making an attempt to slow the cars down.

I think the single cell will work great for that - but so is 4 cell now that CELLS quit exploding... and having the TOP level cells is a lot less relevant if it's in a SLOWER class...or at least it should be.

1c lipo class at ovalmaster motor was 13.5 donated by novak and 1c battery was donated by Danny at SMC. About $140 in money from these companies. Don't forget these companies when you by at local hobby shop or order on line!!!!!!!!!

This thread is 1s Lipo at the Oval Masters not the 2s Orion 2400. Joe please go and take the 2s Orion 2400 stuff and play on another thread.

The SMC 1s pack sells for $55.00 (pack used at the Oval Masters). The kool thing is you can use 21.5, 17.5, 13.5, 10.5, 8.5, etc motors with it. Reducing the voltage makes the car so much easier to drive coming off the corners. Flipper has driven both 21.5/2s and 13.5/1s. The 1s ran 2 tenths slower per lap but he was able to drive the car for a full 4 minutes easier.

SMC has sold out of their first 2 shipments. 1s Lipo racing is coming..............

Big congrats for Flipper's TQ and to Rick White for pulling off the win in the 1s/13.5 truck class.

Remember guys, this was the first ever 1s Lipo race. So everyone in the class made history.

As I keep saying 1s Lipo racing is coming......................

Rick is just lucky that the “real” old man was not there LOL. GOOD JOB RICK! (I watched it on the computer!)

Concerning the 1 cell class, there are two threads about this so I guess posting this on either one will do. I don’t see what all the fuss is. It’s a class, not a nationwide conspiracy to change RC racing. If you don’t want to race in it…….DON’T. Yes, you have to run a receiver pack…..Mod guys have been doing that for years; nothing new. What I see it as, is a way to keep some racers racing that otherwise may want to quit because of the LiPo speeds. Where’s the problem?

I heard the packs are so light that they are trying to stop them from flipping over.

So did they manage to find a setup that helped with traction roll?

No one was traction rolling in the class. As speeds increase there could be an issue because the cars are much lighter.

Yes thats very true, but with track time that can be worked out, just like everything else, It will be a good class. It was a lot of fun!

There was either one hell of a pot hole or.....ghosts!

The way I see it is one cell Lipo will slow 17.5 down to where newbies will feel comfortable and veterans won't want anything to do with it. It could bring an entry level class back. That should take care of cherrypicking. It can't come soon enough.

I think Adam traction rolled in one heat but we found some warped, bent, and twisted junk in hit truck that was causing him to be really loose. Once we fixed that his truck was much better.

Yes they are MUCH LIGHTER but you will need to come up with a different set up. 13.5/1s is not too fast for carpet. I have not tested anything faster yet.

I could forsee this in the VERY near future:

17.5/1s replacing 17.5/4-cell
13.5/1s replacing 13.5/4-cell
10.5/1s replacing 10.5/4-cell
10.5/1s alternate to 21.5/3200

Still some bugs to work out, but 1s Lipo racing is coming.................

Tony-

Why did you choose 36 oz instead of 38 oz? Maybe going forward we could go with 38 oz to allow people to add the weight where needed. It could be a great tuning tool, and also allow people with sliders to add weight as well. I know my Gen 1 was very close all week with only a 1/4 ounce of weight. That is with a 9650 servo in the 21.5 expert class.

Adding 3oz can cause issues of where to put weight, it slinging off during a crash, etc. I think 36oz should be just fine.

I can understand that. I was just worried about the slider cars. There is no way a Gen 2 or a Gen 1 is going to get down to 36 oz.

Either way I am all about the single cell racing, and thank you for doing all the testing. It will be a great thing in the next few years. It can only help make this hobby grow.

1 battery (type) for all classes!!!!!!

You said it yourself in another thread that you guys run a bigger tracks. The fact is that some tracks are small and lap times have gotten to fast in the last 3 years. The advantage of running Lipos has been proven so we need to do something for the smaller tracks who want to run Lipo plus the packs was initially intended for 12th scale cars.

By the way we will have a 2600/24C pack coming out shortly that will be priced at the same price as the Orion 2400/20C pack.

We got the packs in last week and we were amazed by how many wanted to buy and try these. We have sent some to all our distributors and there should be some available. I know Nexus Racing , Stormer Hobbies have them in stock. Horizon will have them in this week so stores can order form them or Barry Hill as were sending some to him. We have reordered some from our Lipo manufacturer as I think the response has been very positive.

Glad to help and I'm sure many will want to run these packs as I think it gives the local track with unlimited speed options plus the price is fair and there is no need to balance a single cell Lipo.

So far the response has been better than I would of thought and we have already ordered another batch of these packs.

Danny, thanks for the chance to run the 1 cell battery at the Oval Masters. There will be a place in oval racing for the 1 cell lipo battery. It can be taylored to any of the current brushless motor winds for what speed the racers or tracks are looking for.
This past race we used the 13.5 motor and the speed was great, like the old stock class.
Maybe a package can be put together with a battery, receiver pack and regulator for pre-wired, just drop in package (no wiring) for convenience. The receiver battery would just be a one time purchase. I got my receiver battery and regulator for about $40.00 total.
Just what the hobby racer is looking for. Little maintence, low cost and only need one for the weekend.

Once again thanks for supplying the batteries.

I would agree on the package deal, would make it better for someone new to lipo or racing by helping them know what to buy.:thumbsup:

We will be talking with Novak about including there Booster circuit with our packs. As far as a regulator goes I'm pretty sure it's not needed and with the Booster circuit it will not be needed.

Just picked up a 1 cell LiPo. Seems like it might a bit difficult to find a place to connect the sensor leads from the Turbo. Any suggestions?

To attach the voltage leads if you want to continue using the Deans connector I would remove the shrink tube on the positive side where the wire solders to the connector. This will allow you to attach the voltage sensing lead there. The you can remove a bot of the negative wires silicone coating and attach the voltage sensing leads on it.

Or you can attach them like the attached picture on the charger connector.

I tried it this weekend in practice in 17.5 class. All I did was take the 4600 out and dropped in the 1c and it actually handled well without any changes. No reciever pack either but I only ran for about 2 1/2 minutes.

It would be nice if the case on the 3200 2C LiPo packs were designed with the "bumps" like the 1C case is.

Danny,
Thanks for all of your support over the years! And your product is top notch. I saw many packs this weekend. And this new lipo pack is the wave of the future! Might I add the color is nice! There was testing done with it at or local track and it went very well. I heard nothing but good things about the new lipo packs. Great job keep up the good work.

For the 2 cell packs we have ROAR rules to contend with and when we released our first 2 packs we mad them so they fit the ROAR maximum size rule and had the best possible cells. With Lipos the bigger you go the higher the mAh or the C rate or combination of both. So adding bumps would mean we would of had to dro the capacity or the C rate. It costs 2500 dollars to mold a case and 1000 dollars for the tooling to come up with a new cell size. So we could of made the 3200 in a new case with bumps but it would of cost us 2500 more as we already had to pay 1000 for the tooling.

As sub-c seems to be on it's way out I would think that car manufaturers may design there new chassis around Lipos so maybe we will see chassis that are milled out to have the pack fit into the chassis and no battery cut outs for sub-c cells.

When coming out with a product it's hard to get it perfect for everyone and cost needs to be considered.

Heard they ran 1 cell 13.5 in practice with some 17.5 Nimh cars and the speeds were very comparable. I'm guessing that 13.5 single cell may end up a bit quicker since they just guessed at rollout and setup since it was the first time out with the single cell.

oh this was in Plattsburgh NY (not ovalmasters)

Speed wise was about 8 laps or so slower (5 min)from 17.5 4 cell to 17.5 1c lipo
