Aim your rollout to be around 50mm (1.97"). That should give you some speed. With your tires at 1.70" (43mm), you can try 31/84.

thanks that puts me in better range. I guess the 44 was a little low then. I'll be at the track tomorrow so I'll try to update what it feels like and temps.

I think you would easilly get away with 60mm rollout on the Black Diamond and a 7.5 on profile 2

started out with a 50mm ro and the motor came off 130 and the speedo was 130 the room temp was 85. went to a 51 on the second pack and it was still only about 130. put 3400mahs back in the pack. so I have more power I can use. so I'm thinking of going to the 55 and trying a 2 dot timing spacer. when I can find it. it's in the pile somewhere. play with that tomorrow.

I have run a 6.5, BD on profile 5 with a 60mm rollout. I would say you are waaaaaaaaaay off the mark. Especially if you are still on profile 2.

Finding the right gearing is part of the fun. Each driver, each car, each track requires a different gearing. With the advanced ESC comes to play, you can fine tune using profiles (boost) or motor timing. The combination is unlimited.

Just keep gearing up until the motor temp hits 150~160F, then you know that is about the 'ballpark' figure and fine tune from there. good luck and let us know your findings later.

Unless you can't get enough power with gearing and profile 5, stay with the 4dot tmming as it will kill your runtime and push temps up quite a bit.

Has anyone ran the new 1S saddle packs on their T-bar cars? If so, how is it compared to a 1S link car?

I know a guy that did and loved it. The only reason he went back to the link car was that he only had the one saddle pack and didn't have time to charge it between rounds.

I would love to get one and break my good ole 12L4 back out.

Yes, very good. I own a TBar S120 and it is very comparable to a link car. If you have a TBar car then you should try this pack out. Speedzone was very easy to order from too.

7.5 lrp and BD testing
left it on setting 2 and 4 dot and went to 60mm ro and it was considerably faster and fun. motor came off 145F and speedo 135 battery was 125 so it did pull the juice. going to charge her up and check how much it pulled. but I think its fast enough to get me around the track. one thing I did do was take it easier on the start so not to kill the tires as last time it fell off about 7 minutes in traction on the rear. probably the fact that we haven't had a race on the carpet since april. I'm going to kick it up to setting 3 and 4 friday and see what I get. 12th scale rocks. quesiton for the mod racers with a 4.5 or 5.5 do you get them 160F on carpet? I was driving it like a stock motor grip it and rip it. I know not the way I should be but just for testing and practice. I mean 145 doesn't sound hot but I don't remember getting a 17.5 with a tekin much hotter then 125 135 at the birds this year.

That you Roger?

Ran the 12L3 at IIC this year using the LiPo saddle pack. Loved it. Not skilled enough to notice a difference from the 12R5.1 that I ran and sold last year.
Good enough for me, handled great.

If getting the saddle pack gets you out there, get the saddle pack.
Hope to race with you soon.

Temps should be much tye same as you will as you will use less gearing and less full throttle.
