The only thing I could blame is the flex of the chassis especially on awkward landings for the 91mm to pop out. I also did not shim those 91mm. Maybe I should have, but I just followed the manual instructions.

Don't get me wrong. I am not being negative. This car has made me super fast. I just need to tweak things a little differently because I do not have the aptitude of a pro. That's the entire reason for getting the Agama mounts and not suffering DNF's for not checking those little screws on the plates.

I hope that makes sense.
The 91mm outdrives popping out was a big talking point and most everyone settled on using 93mm up front. The primary reason for them popping out would be droop setting (or amount of suspension travel), arm flex, steering angles, how the outdrive and diff were shimmed, some combo of all the above. But chassis flex would have little to do with them popping out.

The chassis flex is dominated by two modes of deformation. First bending (think of bending the chassis into a "U" shape. And second torsion (think of twisting the chassis like wringing out a towel). Neither of these types of deformations would be the dominant cause of the outdrive popping out.

I see lots of folks taking about using shock oils measured in WT. I run PT oils and my oils are generally 600/400 with Orange springs all around. I tried 675/375 (almost exactly what 45/30 equals) and my car pushed in corners and was ass slapping all over my home track

I agree monetry gain is the reason. All Kyosho need to do is make the shafts 92mm and ALL the confusion would go away and they would work on ALL 4 corners of the car with ALL the common suspension settings. They just made the shafts thicker, how hard do you think it would have been to start make them 92mm long?
Another thing is why are there 2.9mm pins in the end of the shafts instead of the industry standard 3mm pins? More shaft sales, what else.
Hey I am not against a company making money but I am against unscrupulous business practices.
The pin issue is somewhat circumvented by buying the cheap RTR dogbone shafts and using the pins out of those.
Luv my K Car despite the negatives.

Default RACE SCHEDULE!!!

Hey Guys. I haven't been on RC Tech much lately, so help me out with something. Is there a race schedule thread anywhere? What about a site that has a clearing house schedule anywhere for major races? Hook a brother up!!

Hi Guys,

Looking for a bit more off power steering. Car is great on power but I find I have to gas it to get the car to corner like I want through tighter, low speed corners. Any suggestions?

Thanks

Hard to say without knowing your setup.

set the car on the ground and check the end points, make sure you have full steering.. add some toe out.. check the ride height.. if you still need more you could lighten the front diff oil or less castor.. depends on the set-up.

Hi Gents...

New to the site and new to the TKI3.... For which I am basically awaiting delivery of.... Cannot!! Wait!!

Couple of questions I would like to ask..

Working on a budget so I was wondering what would be the parts I need to keep in my Hauler without going stupid... Ie wishbones etc

I am an average Jo driver that in all honesty was not feeling the love for the 8.2, so I have sold a few things to buy so I do hope it holds up to the hype and improves my driving and most of all makes me fall in love with driving

We have terrible weather over here in the Uk and most of the tracks in the north west are astro turf so high grip tracks so what set up would you recommend

Also is there anything I need to be aware of during the build and anything I might need to do different... I have already ordered the 1.3 x 8 pistons

Thanks in advance for your help

As far as extra parts. Definitely buy some lower a arms, hinge pins and a set of the hinge pin pills. It's been my experience that if you break an arm you'll probably also bend a hinge pin as well as break the hinge pin holder, the "pill". I'd also get extra front shock shafts, upper front arms, a wing stay, and an Etta bumper.

For the build I recommend buying some lucky 7 sealant to use on the front and rear bulkheads where they meet the chassis as well as sealing all three diff cases n

Thanks for the lesson. All I know was the car was having a problem with the Uni's popping out so I went to the 93mm. The chassis flex is probably incorporated into the design of this buggy. That's probably why it drives so good. Too much Flex is also a problem. The BCE chassis is worth a try.

First off welcome and congrats on your purchase, I think you will be very pleased with your new buggy once you get it set up. If you are wanting some spares I would make sure I had a set of the suspension arms, and the bushing inserts. Its kind of hard to predict what you may need but this car so far has been very durable for me. I would suggest you get some shock springs and a couple sway bars since you are going to be running on astro turf, I feel those components will be crucial for all that rear grip. Enjoy your new car and good luck.

Hey pitpop, we need a big name Kyosho guy to show up at the Fall Brawl held in Myrtle Beach SC the first weekend of Decemeber. Mayfield and Drake are 2 of the usauals that show on the non Worlds year, Lutz has also came for a couple of races. I can give you some more info if interested, otherwise I just follow RC Signup and watch our local & reginal forums.

Here's a video of last years layout, Larry (BigBird) Ward usually helps out the badland crew with a great layout every year, track will groove up in a major way resulting in some fast racing.
