Glad I can help
The front of my car is really stiff with that setup just to calm it down. There isn't a huge amount of weight transfer to the rear with this car. I've been think of ways to move the battery farther back. No, I haven't tried that position. I would think that it would make it very unstable

I tried the inner holes on the arms and you are spot on. It made the shocks super soft throughout suspension throw and made the car unstable. Drivable but not very good.

Not sure what the problem was but even with 1.3x8s the car was still bottoming out hard enough to pop the front end back up this weekend. That was with 35/30 oils. Admittedly it was at a big track (Cape Fear), and it was with X-ray pistons. I had to go to 1.1x10s and up to 45/40 to compensate. I think I may just go back to stock. Seems to suit the bigger stuff better. Although the X-rays were traditional pistons that may explain it?!?
I was just thinking of buying the 8x1.3 to get more pack. We were having the same problem, so maybe I won't get them.

So only my second race with the EB48 this weekend, and it was a big race. The track was super dry (18 x 3 qualifiers + main, without wetting the track, just blowing it off). I absolutely like a little slide to the rear of my ride so I can power slide/drift around the corners, but it was a bit out of control this weekend. Going from my truggy which is completely dialed to my EB48, it felt like I was running on ice. The back end was sliding everywhere. The surface was very dry, bumpy, and hard packed, but with layers of dust depending on the area (dry dirt/clay, no where near blue groove).
I know this might be the issue (tires), but let me give you an idea of what I tried from big to small
Calibers
Impact
Sniper
Holeshots
Hybrids
I'm running the Austin Blair 02.28.2013 setup with stock pistols (have the 1.3x8 tekno I can try) with the kyosho light blue front orange rear.
Forward bite with the calibers was just amazing. I was turning what all nitro 1/8, truggy, and most 1/8e use as a double double into a tripple single or even single... but the second I got just a little too much steering on the corner that back was coming around and spinning out. It made for some cheering and yelling for high flying in the A main, but too many spin outs landed me only towards the middle of the pack instead of in the top four like I wanted.
Thoughts?

I like I beams, crime fighters and enduros. Soft in the summer and super soft in the winter...the I beams are my favorite, then the enduros and finally the crime fighters.
my buggy is lite weight but so far I really like 10x1.3 with 32.5r/37.5f...call me crazy but its nice. 5x1.1+5x1.2 with 27.5r/32.5f was like a brick and 5x1.2+5x1.3 was still stiff...but again, my buggy is a little over 6lbs...also I could care less about bottoming out on jumps so I tune my shocks for the rest of the track. 2 much pack or stiff shocks on a bumpy outdoor track = crap imo

When I built my kit I was reading all the info on here about pistons and was determined to drill out a few holes. All I had was a 1.6 bit "thought it was 1.5" so I went ahead and drilled 4 holes in each 10x1.1 piston leaving me w 6x1.1/4x1.6 total hole surface of 13 like the 10x1.3, 35/30 losi was way to light, I ended up racing w 45/35 losi but this week I went to our indoor track and bumped to 60/50 AE "I kno it sounds way heavy" but It felt much better, granted it was on a smooth indoor clay track. It seems soft on the bench but seems to pack up well over jumps and lets the car roll enough in the corners for traction. It may be too heavy for a bumpy track, we'll see. I did order CSI blue v-ports that should be here 2day, 2.8/2.6 swaybars and tires/wheels should be here soon too.

[QUOTE=SMR 510RR;12193365]No, you have it backwards. In a MX shock more pack is more rebound dampening or a slower rebound.
thats what i said read it again.

It would probably be good to have this information on the OP so we can stop having the wrong info pop up once a week.
Since this is about RC we should get the RC terms right maybe you should read it again.
That would be the same thing same term. What it should have said was in RC pack refers to how much stiffer the shock gets when you increase shock shaft speed generally helpful in the compression stroke not rebound.

Everyone keeps getting this all screwed up. From what I understand (I am also a newer owner) the kit has always come with the 10x1.1 pistons but people were having issues with the pistons being slow with the recommended oil so Tekno said to drill all the holes out to 1.2. Then they were having issues with not enough pack so they went to the 8x1.3 which has less pack that the 10x1.1 but more than the 10x1.2. Someone please correct me if I am wrong.

SMR is correct all the way around. skinnyricky is correct on the MX terminology, but off on the RC term.
Here's a pretty simple explanation of the discussion.

10x1.1 pistons have the most pack of all the options...Sounds like you may need to go to a heavier oil or spring if you are having bottoming out issues.

I built by second kit with all the aluminum pivot balls ,all the pivot bushings , drive shaft ,cf towers .
Lol but after installing airtronics servo ,rx8 T8 1900 and a 630g battery to balance car out still came out to 7.7lbs ...
My first car i built was kit with the heavy savox alum servo, Hw 150a , denamic8 2200 and a reedy5500 comes out to 7.6 but it isnt balanced. Go figure .lol

Thanks, it looks like I got it backwards. It gets very confusing at times. Saved me some time and money though.

Here is a list of Teknos CNC pistons that shows the in order of pack. It should also be noted that other design features of different manufactures pistons may react differently, a notable one would be the Kyosho black 8 x 1.3 pistons because of their angled holes.

rear diff pinion bearing wear
Tekno RC and everyone -- I am going through rear diff pinion bearings pretty quickly. I get about 2 races days out of a set bearings. This seems to be excessive to me. The buggy is fantastic but it's looking like I need to replace those rear pinion bearings before each race to be safe. Is there anything that can be done to mitigate this premature wear of the bearings?
