The the motors to do this are called brushless motors and they cost less than $150.

I answered a motor question don't read anything about a change of opinion into that.

IB3800's are an absolute necesity if you race stock or 19T but are not as good as GP3700's in Mod.

Adrian I really don't know where you come up with these conclusions about IB cells but you don't have it right. IB3800s are better for every class because the have higher capacity, higher voltage and lower IR than any other cells.

Heya GUys.


I haven't as yet tried IB cells but i am getting some early next week.....

As for GP37's i think they are an average cell at best!! I have 4 packs that a 7 runs old now and they have dropped 35+ seconds on a 35amp discharge on my T35. The first run they did was on my T35 so i had a bench mark to work with.

I haven't deadshorted them, they have always been left with some charge in them..... they are pretty great for voltage and IR currently....but in mod TC a 330 35amp pack won't cut it! more so when they were first cycled they cycled out to around 380!

Since you store them with charge you should do 2 cycles and take the readings on the second cycle. Do a cycle one day and then another the next. I'm sure the capacity has dropped off but maybe some of it is due to the capacity stored into the cells. GP cells are known to have lower runtime the first charge after they have been stored with charge.

Heya Danny.

Funnily enough that is on the 2nd day!

I went up to practice for one of our big state races, and couldn't make time.....same motor, gearing, timing and batteries as i had used maybe 3 weeks earlier.

Got home put it all away and the following day cycled them through and i ended up with these numbers.

Label:393, 1.169, IR2.3
First cycle:365, 1.17, 2.9
Last weekend: 340, 1.158, 2.9

Label:391, 1.168, 2.3
First Cycle:381, 1.165, 2.7
Last weekend: 340, 1.160, 2.8


Label:381:. 1.165, 2.6
First Cycle: 376, 1.63, 2.7
Last weekend:330, 1.158, 2.7

Label: 383, 1.169, 2.3
First Cycle:376, 1.165, 2.8
Last weekend:334, 1.158, 2.9


First cycle was when i first built them up, the one last weekend was the day following my practice day, probably sat for 12-15 hrs then discharged to 5.40 on the T35 and then on a tray to .9v per cell.

All charges done @6amps, [email protected] cut off 5.4v

For those who are doubtful that the IB cells are not good for modified racing I got a little video clip for you…. Setting; JMRCA nationals, Mod Touring (8 minute racing)….. Masami is using IB 3800 cells & Hara is using GP 3700 cells…..Check it out (warning!!! 55Mb file size)

Thanks for the Vid Curtis!!! Its incredible what Masami can do with a car. In that series, aren't the motors like a 12 turn limit? Its wicked you can run any mod for 8 minutes and go that fast! Maybe its time for the U.S. and others to step up to 8 minutes?

Just to brag a little, I just got a couple sets of IB38's today. 1.204 at 1.7 IR and 1.205 at 1.8 IR. Wow! My last set was 1.186 at 1.7 IR. Damn these are cool.

Hey Curtis, did you also find a video of the 2nd - 3rd final as well qualifying?? The race is decided on 3 finals, not on one... and which battery TQ-ed?

Yes, IB's are good, but correct facts please....

Actually he presented the facts as they were re-read his post.
Unless you are reading something into the post that wasn't said...

Congratulation on your win Oscar but it was fun to see an IB pack and Yokomo motor be able to keep up then pass and check out. Since we know that IB cells are better than GP cells it was great to see it on video. From what I heard Masami was taken out in the other 2 finals.

We also got info from a real reliable source who tested the special GP cells you guys are running and he told us that the IB3800 is still better. Maybe you need to talk with IB and get some for the Snowbirds.
