I got to run my TB03 along side a TB04 we'll equipped and equal drivers. The first thing I noticed was the car rolls a lot more with similar oil, springs etc than the 03. It seemed more aggressive and less composed. Lap times were about .2 off the 03 with nearly identical equipment and setup. Also the gearing became a big issue. Figuring out a solution is going to continue to be a pain. This was in USGT on carpet. I'm sure with some alterations on setup it will be closer to the 03 but I'm not seeing any improvement.. Plus it's quite a bit louder!

thanks, so the largest 64p pinion will be 47t, can some one confirm if a 78t spur will work without any mods, about to order some gears and do not want to waste money if 78 does not work, thanks please help

imho, depends on what you want to happen...

forward, easier to drive
rearward, more turn-in

hths





BTW, had our 1st race with the TB04s last Saturday (the 25th)... while my car was totally out of pace (1 lap down, finished 3rd), 1st and 2nd was fought out tightly between a TB04 and a TA05v2.... TA05v2 won the race. But I'm not surprised given how many seasons of set-ups the driver has on the kit.

The 04's should be very competitive after a few more races to learn more about how the set-up the car.

But in fact my car is not finished yet.
Could you tell if this car is good turn 1?

My opinion is, this car can't be better than other cars to be too heavy.

Even i go to use shorty lipo, but with Tamiya R8 body, so weighs around 1450G, i guess?

If is heavier than this weight i should put the car more turn in, isn't it?

Best regards

No sense bench tuning, imho. Put the car on the track and see what it needs from there.

I finally got around to weighing my race ready TB04 and 03 (without bodies), both with spools and ball diffs. Both cars have identical radio gear, motors, tires, inserts, fans, steel ball studs, short front shocks, tb03D rear shock towers. In short, They are as the same as two different platforms can get.

Here is what I found:

Tb03

Total weight - 1355
Front weight 47.5%
Rear weight 52.5%

Tbo4

Total weight - 1367
Front weight 47.5%
Rear weight 52.5%

The TB03 had slightly more left side weight (50.8% vs 50.5). As a recovering oval racer, I think the 03 has an edge at the Tamiya circuit because of the number and makeup of the track (where the highest speed turns are left).

Note - body posts are NOT trimmed on the 04, which ICRC would wack another six or so grams off of it. In short, they aren't that much different on the scale. Add gear diffs and it's off to Jenny Craig or Weight-watchers!

Has anyone had inconsistency issues with the car? My friend raced his this weekend and it would run good for a few laps, then he would bobble and it would hook around one way and eventually start running normal again after a few laps. I'm wondering if it's holding tweak from the bobble and working itself back out. If he runs it again, I'll go over it better and see if I find anything. I'm thinking it could be the aluminum screws he has on it. Maybe they are not torqued down enough. I did replace the front aluminum screws with the kit screws for the front wing stiffeners. I also think maybe it's the battery hold down tabs. Any other suggestions?

is he using the high torque servo saver? those are notorious for getting tweaked after a hit...

He is using mine with the aluminum horn, but it's not that. I haven't had an issue with it when I run it in my TA05 and another guy borrowed it last week with no issues in his TC6.2. Plus it would not steer straight if it was the horn. But good call... Wait a minute.... Did I let him use my horn?? Hmmmmm hehe. Damn it I'll have to go look. hehe
