only a flashlight racer would ask "what Mah pack and what kinda runtime ?" in the nitro offroad , you silly focker!!!


1800-2700Mah 2s lipo should be fine Joe

lmk what servos those are before you run unregulated , kinda hard to see in pic , i have a regulator you can use if necessary

I run a 1700 Life as well as a 2100 Lipo. A 15 minute main, 3 qualifiers, and a little practice only takes about 500mah out of my Rx packs.

Hi guys
Today I went out again to my local track with the tki3
The car is really good hooked up and planted.
The more I drive this car the more I realise that every cent spent is well spent.
Once again thanks to kyosho for a great product.

Hey guys, in general most setups I look at the arms are using 11 degree bushings and in the lower position both upper and lower arms. What would change if you run the arms in the upper positions instead? It looks like most of the K-car drivers had the arms in the upper position for World's and what just curious of how that would feel?

Ok, just so we can all get on the same page here - typically, you refer to the 4 lower hinge pin holders as A, B, C, D, starting from the front of the car. So Front-Front is A, Front-Rear is B, Rear-Front is C, and Rear-Rear is D.

So, you're referring to the A pill setting, running the dot in the highest location, which gives the most kickup (11 degrees). When you run the dots in the lowest location on the A pill, you get less kickup (9 degrees). The upper arm pills are independent of the lower A pills - sort of.

The Kyosho Setting Guide is a good read - pay particular attention to when you run less kickup on the A pill - you run the 9 bushings in the correct orientation on the upper hinge pin front locations (instead of the normal L and H pills). That is the only time you need to adjust the upper hinge pin location when you adjust the lower hinge pin location.

The reason you do this is because you want to keep the upper and lower hinge pins parallel on a c-block suspension so nothing binds up.

When you run the H pill versus the L pill, you install the H pill but must also flip the rear pills so the holes are on the top now. Running H versus L lowers the front roll center, giving the front end more freedom to roll - it typically is felt getting into corners, and helps the front end get into the corner a little better.

Hope this all makes a little sense...

If you change the front upper arms in the upper position, as opposed to the lower position, you are changing front roll center. Rasing the upper arms lowers the roll center. A lower roll center increases the distance (or moment arm) between the roll center and the center of gravity. Lower roll center makes that end roll more.

The lower position gives you a higher roll center, or less distance between the roll center and the COG, causing less overall roll.

Interestingly, the Hudy setup guide

www.teamxray.com/teamxray/showfile.php?file_id=4461

The The Guide by JQ

http://jq-products.com/the-news/43-t.../160-the-guide

have two contradictory statements about front roll center and the front upper link. I believe in this case, the Hudy setup guide is actually incorrect and The Guide by JQ is correct.

Higher roll center causes more initial steering and faster steering response, but less traction later in the turn all because the chasses rolls less.

Lower roll center causes more chassis roll. It may feel lazy especially when you have several quick turns because the chassis rolls more, but you will tend to get more traction from mid to exit steering.

Yeah, the offroad guide by Hudy has it backwards. They have it right in the touring car guide though.
