hey guys,

Do you feel there is a significant benefit to running short packs in your B4s? I have an arsenal of standard sized LiPo packs but I am thinking of getting some short packs for my B4.2. They won't work in my DB01 so they will be specifically for my AE car which is kind of a unique expense. Those who do run short packs, do you run them forward or back? (high bite clay for me).

Thanks for any opinions!

I ran shorty for most of last Indoor season. Then I spent 2 track days going back and forth. The full wolf pack produced the same exact fast lap time as the shorty. The gain was huge increase In drivability. My top 5 and top 10 laps were way faster and more consistent.

If you run stock... I'd say shorty would have to be the way to go though.

I started off running my B4.2 with 5800mAh packs. Way too heavy IMO, you have to adjust suspension so much to keep from bottoming out. That is my experience at least. I switched to shorty 3800mAh packs and put them all the way forward. Jumps much better IMO and less weight to pull around. Run time is less but not terribly so.

I am doin the same....I can take my shorty and move it around and notice a considerable difference , so I only run shortys in my buggy, for sct I don't like shortys lol but that's a dif thang haha

This is great info, thanks guys. I will shop for some SMC or possibly Turnigy packs to get me started and go from there. Thanks also for letting me know how you guys are orienting the packs in the battery tray.

Thanks again!

SMC Batteries are great! that's what I run in mine

4700mah 70c shorty packs

way more punchy than my reedy 4100mah 65 pack. both bought at the same time.

I will say this, there can be a huge difference in companies full packs. I used the reedy full 5000 wolf packs. They are a lot lighter than other heavy full packs. Shorty does jump and land better but after lots and lots of testing, it didn't matter on the clock. Shorty just didn't produce overall in a whole race. Drivability and consistency is way better with a full wolf pack.

Those batteries are great but honestly, If you want consistent batteries that stay the same the whole run, spend the money and buy a top of the line battery, especially if youre running stock. I have ran some cheaper batteries with high C ratings($45-$60 range) and they are great at first, amazing power but they fade off quickly and it only gets worse the older they get. Then I bought a Thunder Power 65C 3800mah shorty ($80 I think, not super top end battery) and the difference was incredibly noticeable. It lacked a little punch but the battery had the same exact power until it cut out due to voltage. It was great for the 17.5 motor I was running at the time, could clear the triple every lap whereas I was casing it towards the end of the heat with the cheaper batteries, which was important. Just my $0.02.

Just by shear numbers, a 3800mah battery is going to have a lower average voltage after 6 minutes than a higher mah battery for the same discharge rate. Your selling yourself short by running 3800mah. No battery has the same power at the end of a run as it does at the beginning. Put your 3800mah batteries on a PowerLab or Turbo35 and I bet you'll be surprised what you find out.

Also, just because a battery is more expensive doesn't mean it's better. If that were true, then everybody would be running MaxAmps, and all the other overpriced batteries on the market.

I have several friends that run SMC and they love them. I know SMC tests all their batteries as well. My Fantom's are also tested and if they don't match his standards, Fantom doesn't sell them.

I'd wait and get an Aero Model. They should have more in stock the beginning of Jan.
