Hey all: kyosho has a ton of talent and a BIG budget so they will get their new 10th 4wd figured out. Also are aluminum chassis the wave of the future or a fad? Thanks

A grip that didn't eat tires like this 2013 Worlds, but enough to make a great race, maybe almost interesting than this year except that both 2WD and 4WD were decided after two runs.
In Europe, I don't see the sugar thing happening. That was a different surface and IFMAR chose a better tire for the spec tire. This time they chose one of the hardest compounds made. That meant the track had to have insane traction.

It is here in the US that I see it becoming the "normal" thing to do at the national level. I hope that the national level events don't do this and go back to just sugarless prep.

Meanwhile, the picture of the ZX6 (and the Durango prototype) with shorty on the rear/one side, and motor on front/other side makes it easy to have front/rear overall balanced, and left/right overall balanced, but weight may be too much on rear right and front left.
Did anybody else notice that ?
I think you meant heavy right front/left rear?

For this 2013 event, the track had tons of traction, but was racey and you could still slide and pitch it a bit with the tire selection...then it rained...a lot...

The rain packed and textured the track more, and required re-sugaring which all equated to a bunch more traction than it had been scrubbed in to have. The big thing with this though, is that it didn't fall apart and need a bunch of patching.

For 8th scale, I like BOTH the high bite and the more fluffy watered tracks. They have different feels to them, but on the high bite at a club level, you can simply throw on some slick worn out tires and run them and have fun...all day...including lots of practice...without the traction condition changing on you.

Unfortunately, that doesn't work for 2wd cars, and slightly less well with 10th scale cars (though I get away with it on my SC). I think a 4wd buggy could do it too, but perhaps requires a center diff to get that portion done right and make it just as drivable as with having tread on all 4 wheels.

Hey Guys,

Just a heads up but Tebo was also having ESC issues at the worlds and didn't figure it out until the Q4 was done. He was running sensorless and when he changed it before Q5 he said the power difference was like going to a 3.5 bl so it was a handful.

Kyosho will make some changes and this is a project that takes some time to perfect.

This doesn't make any sense to me. They shoulda been popping in new electronics like bearings until they fixed it. It's a WORLDS

When I had a sensor wire get loose on a buggy recently, I noticed an issue almost immediately. Tebo doesn't? If it affected the car in any significant way, he wouldn't notice?

From Buggy Sport/Jared's Blog (regarding the 4wd)...http://www.buggy-sport.info/index.ph...ce-report-6635

"Sorry for no updates on 4wd. It was a very tough 3 days, and I was just exhausted. Practice day was crazy. We had 10 practice runs, but I only was able to finish 3 of my runs, so I missed out on a ton of track time. I was just having really weird mechanical issues. My car felt ok, but I really lacked steering in the 180 degree corners. I was making setup changes all day, but I wasn't getting enough track time to really see what it was doing.

Qualifying day. The morning practice my car actually felt pretty good. I was placed in the A resort heat, even though I only did 1 lap in the seeding practice. That was a good and bad thing. I would always start in the back and then have to pull over and let the faster cars go by me. Once qualifying started, I thought I would be able to get some good runs in, but it just didn't happen. I wasn't comfortable, and I was still having small mechanical issues. My electronics just felt weird. In Q3 I was actually going really good and was looking at getting a 6th for the round, but with 1 minute to go, I brushed a pipe and caught my wheel nut on a coupler. Front arm broke and the drive shaft came out, so I drove the last minute with 3 wheel drive. I got a 41 for the round, that was my best score all qualifying. In Q6 the electrical gremlins finally showed themselves. It was a shorted out speedo the whole time. I ran the whole Q4 in sensor less mode, which isn't fun, but then it finally shut down after about 4 minutes. In the final Q5 we had a new speedo and my car finally felt more normal. In practice and qualifying my car was feeling slow, so we had boosted the speedo and geared up my car. With the new speedo, my 5.5 felt more like a 3.5 and I just couldn't time any of the jumps. After 1 crash the top guys were behind me and they were fighting for TQ, so I had to just pull over to not interfere with their opportunities. It was quite an embarrassing day, but I did manage to live through it. Here is a pic of my car before practice started.

Finals day was weird. I wasn't there with a chance to win. I started 8th in the E-main. Morning practice my car was ok, but I made some changes for the final. My car in the final felt really good in the turns, but landing was a different story. I guess what I changed really effected the landing. I could not land the triple after the straight, I would roll over every lap almost. I tried my best, but I finished 4th. 4wd was finally over. Chikuba, Kyosho designer, felt terrible. We win as a team, we lose as a team. We didn't have a car that we thought we could win with, so we came with a prototype car hoping it would help our chances. We learned a lot, tried keeping our heads up, and we took the loss for what it is. We will be back in 2 years for 4wd revenge!!!!! Thanks KYOSHO and Chikuba-San for all the hard work and the great support!!!!! Sorry for the lack of updates, thanks for checking back in, and God Bless."

I ended up really liking the varied surface of the 2011 Worlds. My initial reaction was that of "what the heck is this" but after I thought a bit, it resembled something we would have done as kids canvasing the open lot next to the house for anything we could build a track with. Once I had that perspective, I really starting thinking about how much time would have to be put into setups since you were running on so many different surfaces (dirt, cobblestone, astroturf, etc) and started to appreciate how cool it really was. I'd like to see more tracks like that.

So is it back to the drawing board for the zx6? Is the car that bad, because it did poorly at its first big race. Im not sure what to do since I ditched my fs2.

The ZX-6 has not been doing well at any race it has been run and the Worlds just exaggerated it. My understanding is they there is going to be quite a few revisions and to not expect the car anytime soon.

I don't know why people get rid of their cars when a new one is coming out. I bought a new fs2sp just a few weeks back with full knowledge of the new cars coming out, even getting to see two of the prototypes in person. People were saying "Why on earth did you do that?" Simple! I wanted to race 4wd!

Not sure what constitutes success, but there was one in the A-Main at the Nats, and B-Main at the worlds. Considering not many people driving them.

That being said my guess is May 2014
