Hey guys I was able to get back out and try a few changes to the ET48. First I'd agree with others that the 10/15/5 should be the starting point. Thus truggy turned in over the e-buggy and SC on a very small tight track. To help lock the rear end in a little more the rear camber link is full short and low on the tower and 1 hole out on the hub with 1 degree of camber (Thanks Daniel). I'm thinking that 7 might be better in the rear diff over the 5 but I'll test that at Motorama.

Mark basically you have come to the same conclusions as me I actually recently switched to 15/10/5 I tried 15/10/10 and 15/10/7 and found it to be too pushy

I'd get a front shock tower too. Three guys at our local track have broken a-arms and in all three cases it wiped out the shock tower too.

With a 2000kv t8 4s lipo and 15t what speeds are you guys getting?

My bad man, I under stand now what u was asking.
My truggy won't be here until Thursday. Sorry man.

Metoo - If you slide the motor out of the motor mount you can remove the center diff by removing the bottom 5 screws.

Mamdot91 - It's not about speed in IMO but more about overall performance. If the motor feels good, pulls good, stays within temp and it's not tapping out half way down the straight then the overall speed of the vehicle doesn't really matter.

I don't get it. The motor doesn't hinder removal of the center diff. As I see it, there is a 9 screw minimum effort:

2 mounting the center brace to chassis
3 mounting the motor mount to the chassis
2 mounting the rear diff stand to the chassis
2 mounting the diff cover to the rear diff stand

I'm not sure it you actually managed a 5 screw method, or just forgot about the diff cover and that the chassis brace which is attached as well. That's at least another 3 screws to deal with plus the 2 (for a total of 10) that your remove to get the motor out....which I still do not understand the benefit of. A step by step instruction would help me if you wouldn't mind typing it out.

Real close to 40mph with med compound tires. The softer the compound the more they balloon. So super soft tires with that gear would be close too 43mph.

The 5 on the bottom holding the mount. The 4 holding the top plate and the rear and center braces if you still have them on. That should be it to get the diff out. I never took the motor off to do the center diff. I can make a video if you need it.

As mentioned several times in this thread by me and others, I hope tekno implements a split center diff assembly on the eb48.3

Hey grim I see you are in Michigan. Me and scorpion are coming up march 8 to ams. Have you raced there? Whats the track like for tires?

egobrkr - AMS is simply awesome.

Mark

Nope, that's cool. Seems it's not less than 9 screws for you either, if using the center brace.

SERVOS

Okay, so I found out withing 10 minutes that I made a bad choice in steering servo. There have been several postings of the servos you guys are using. My question is,.. What would you say is the minimum torque and minimum speed for truggy racing?
