I usually set my brake strength to around 70% on the ESC then dial it in with brake dual rate on my radio. It's very track dependent, but I typically I like my brakes to be as strong as possible without locking up. After dialing in your brakes let us know if you still have off power rear traction issues.
Thanks, will adjust my esc and try it

Why, It has a great layout as is. I think its a hallmark of Tekno, nice and narrow. No complaints here, from any of my EB48 buggies or truggies. The only thing that perhaps the narrow cars can not take advantage of, is the newer aero bodies of the wider cars.

Driving on a loose dirt, going to a straight away to 180. My rear looses traction when breaking, do you guys set your brake force to less than 100% I already tried to lower my shock oils and spring but still could not perfect the turn unless I really go slow on the straight.
*Go up in centre diff (if you have 7k, go to 10k) and go a little down in rear diff (to keep on-power stability).
*Reduce rear droop!
if not enough:
*add rear toein
*Go harder in front spring, go out your shock in front arm and use thicker oil in rear shocks
*Reduce kickup and front toe out

how does a low profile 4s battery affect setup and handling? My batteries are 4 ounces lighter than the normal LiPo?
This is the LiPo

Thanks!
OR would the heavier (normal) battery be better?
thanks

Hi guys - I have a couple of questions.
So I raced my EB48.4 and ET48.3 this weekend.
EB48.4:
1). I couldn't keep it straight on the straightaway.
2). The nose loved going up on every jump.
3). The rear-end liked to kick out on me on nearly every turn
I set the buggy damn near to Joe Bornhorst - even the springs https://wwwcdn.teknorc.com/wp-conten...gh%20Track.jpg
The one thing I didn't adjust was my droop. My droop screws are all the way up.
ET48.3
*I have x2 of these... and both blew a diff* - One truck blew a rear diff, the other a front diff. A lot of people were puzzled by this at the track as they haven't seen a Tekno do that before. I'm confused as to what I did wrong on these? When I got the kit I had to contact Tekno because the spider gears were not moving freely on the cross pins what-so-ever. At first, Tekno denied that could even happen, but after sending them a video they sent me replacements for both trucks. I confirmed THEY spun freely and installed them, but yet this? Did I shim incorrectly? Is there something else I'm doing wrong?
I plan to tear them apart tomorrow. I'll update what I find but sheesh... I've never had x2 blown diffs on x2 cars in the same day! I've been building these things since my first Futaba FX-10 - not to say I didn't do something wrong, but unlikely IMO. Any ideas?

1- There are lot's of things that this could be. You could just need a little more front toe out. Limiting front droop to the correct amount will help. Joe has the wheelbase full long, shortening it will help lock the rear in when you're on power. The setup you listed is running unis, CVs will be more locked in on power and in general have a "stiffer" feel all around.
2- The wheelbase, droop, and use of CVs would affect this. But the biggest thing is just throttle control. Most of the time you should throttle up the face face of the jump and let off right at the end. This should make for a mostly level to slightly nose down in air attitude.
3- When you say it kicks out, is this while you are on or off throttle? His setup should be a little loose off throttle. A lot of pro drivers like the rear to rotate easily off power and square up hard on power.
Another thing about his setup is the lack of steering limiters in the spindle. It's probably best to run the screw with 2 washers and set your end points with those installed. You'll find the steering to be a lot more consistent overall and the car will be easier to drive.
