12th scale racing is SA is not a big class by no means at the nationals, but when it comes to competitiveness on track, it's like a full on dog fight at the top and a spectacle to watch. I know where sageyoung and slidemaster are coming from with these questions, if they turn to lipo before the other guys do they might not be able to compete at that top level until everybody has taken the leap to lipo.

Maybe sage and slide must get together to do some testing and let us know.

That's impressive, I usually have been putting a maximum of 2200mah back in on 17.5 1/12, 2800mah on 13.5, and 2600mah on 13.5 WGT.

you will not be competative 4cell vs. lipo. no testing needed. guys that I usually run along side with, I was putting laps on this weekend. they ran lipo and 1 ran 4cell. i guarantee that winning this way is no fun. I just gotta get another lipo for my 17.5 car. the split of the class will not last long. I know the guys down there in SA.

hmmmm I think I need to get a pack and try !!

im leaning toward the class.... i like it and would like to get involved at the nats.... i'll let you know how things progress speed merchant style...

good choice.

I ran the same race with Scottrick, and we were compairing notes on ma back into the lipo cells. I was running right at (well one round just a little under the 700gr weight with a DUO 10.5, Tekin RS and I put back 1800 - 2200ma based on how hard I ran the car. I did TQ and won the class, so I was pushing pretty hard.

I really liked the small amount of tire wear and how "reactive" the car felt. It did not feel as you were loose on the rug, but really hooked up.

I know our club will still have 4cell, but we will use it as the starting class, with the faster racers going to the lipo option.

Were thay also running 17.5 with the lipo? If so thats not even a fair comparison, if thay switch to 13.5 it will be very close but the nimh will still have a slight advange in the infield

As to the question that was posted by SlideMasterR; if your allready running a 4.5 it will be hard to "motor" up. I have'nt tried any mod motors myself but baised on my experience with spec motors, imo you will be getting lapped by the the field if your the only 1s lipo.

you are highly mis-informed about 1s and 4 cell. kn7671 posted our race results. it may be in the vegas thread. but I ran 4 cell 17.5 and 1s 13.5. in my 4cell 17.5 car my best lap was a 15.0. i have run this car for 1+ years now and currently hold the track record for stock 1/12, the previous track record for stock 1/12 and the track record for 1/12 stock on the track before that. so I guess I am pretty consistent on our track. this was the first weekend on this track and the first weekend with my rev5lipo.

with my lipo 13.5 car, I managed a 14.7 fast lap. this is with the car running a box setup basically. so I still need to work setup. so if you think .3 seconds is close enough. lets just put that in perspective. at the end of an 8min race that is 9.6 seconds. that would basically put me another lap up. that would have put me less then a lap behind dumas. I guarantee that I am not that fast.

now in comparison. AWD managed a 15.2 with his 1s 17.5 car. that is just .2 slower then my fast lap with 4cell. he and I are real close as far as speed. and he has been practicing a little more on this track. this weekend was the first time I have been out on this track. so I am pretty comfortable saying that he has a fairly good setup for his 1s 17.5 car.

really running motor for motor is the only way to go. I have heard from some of the top tracks that 17.5 1s is only about .1 -.2 slower then a 4 cell. really the 1s looses on the straights, but man does it move well in the infield.

on a side note, dumas put a 14.0 down with his 13.5 1s rev5lipo

So 1s sounds pretty close to 4 cell. The loss of weight in the infield is making up for a small loss of speed on the stright?

Well then its a good thing that you can clear this all up.. as you clearly know it all In your example you used one sample your best lap to decide that you would be a full lap up. If you can run your very best lap every lap for 8mins then you are the very best driver in the world, my hats off to you.

As an average driver I'll lose that small advantage that nimh has by tapping a board or getting hung up somewhere; thus the 13.5 1s vs 17.5 nimh is very close for me and I'll bet for most of the vast majority of club racers.

Now that you've made me aware of your expertise I certainly wish you well and expect to see your name at the top of the A-main, move over Lia and Blackstock.

in my example i used best lap because what else can you use. well let see. I ran both classes. my best time with a 17.5 4 cell was 31 8:10 and my best time with 1s 13.5 is 32 8:14. this is me with a 4 cell and me with a 1s lipo. both on the same day. so pretty much the same track conditions. we have 4 racers in 17.5 and 8 in 13.5.

hmmm i don't see how you can say they are close. not even. try it yourself, run both classes the same day. talk to some of the other. I have not heard very many people say they are the same, now that people have started to run 13.5 1s and 17.5 1s

you are right. move over lia, blackstock and dumas. i am coming for you!!!

your example makes no sense either. if you tap a board with 4cell, you will tap a board in 1s. so there is still an advantage. are you saying you drive better with a 1s then a 4cell? or are you saying that with 1s, your extra speed buffers the mishaps that you have on the track?

it is close, but a .1 or .2 sec a lap slower is still slower. but most of our drivers are headed he lipo route. main reason is because that is the way the hobby is going.

don't get me wrong. I don't care either way. i just don't like the in between. 1s does have some advantages. but they are not as big as most will try to sell you on. the biggest advantage that i see is that I do not have to deal with my batts on the weekends that I don't use them. you just can not ignore your 4cells for very long. I have 1 cell in a 4 cell pack go zero volt because i have not run them in 2 months. that is really the biggest advantage to lipo I see.

Oh trust me I saw the light with lipo's. Not discharging, equalizing, and long charge times. Lipo are charge, run, charge, run. It is pretty cool. We have a new track opening up and not a lot of known 12th scales around so I am hoping our club goes lipo from the start. If not .1-.2 a lap is pretty close in my book but I am an offroader. We don't usually have ultra close consistant lap times due to bumps and jumps like you onroad guys do! Thinking I might just start out with the 1S 17.5 with the novak booster setup and go have some fun.

i would if i were you. there is really no reason to continue to buy nimh. roar has already state their lipo rules for 1/12 and scotty posted his for vegas. lipo is really the only cells to buy now. I even heard a rumor that some of the big suppiers of round cell are no longer bringing them in and that the only ones they will have available are for team guys going to races that require them run round cells. if you end up with a racer that clearly has an advantage due to running round cells will soon get tired of beating you. racing is about competition.
