Not down there. But at our local club race we have two people that wheel the Kyosho ST-RR. The truggy does handle pretty well. But like many say it is a rich mans RC8TCE.... and I loved my RC8TCE-e before I drove the Tekno ET48. Even if I wasnt on the Team I would still wheel this thing day in day out!!

Sounds like you got your Tekno Dialed in.

This past weekend at the Mountaineer Trophy Race in West Virginia really made the ET48 shine on the track. The truggy out turned any other truggy on the track. Heck it even out turned my EB48.2 if every corner and that thing turns on a dime... The thing is amazing and is so stable!! Best truggy I have ever drove hands down!

How much camber are you running on the Tekno truggy.

Ran an electric. Didnt really care for it as much as the tekno

I've ran the Tekno ET48 and felt it easier to handle than the Kyosho Truggy.

How does the Tekno ET handle when you turn a corner and give it full throttle. The Kyosho truggy tends to lose traction when you give it full throttle out of the corner.

On the high bite track at WFO Raceway in Maidsville, WV my ET was actually turning in as good as my EB48.2. Applying throttle on corner exit was no worry. The back-end stayed planted and did not really have any wash out to it. But when it did, it was very controllable.

I have also ran the ET on less than high bite surfaces. And was very confident in the rear end staying where it needed to be. But if you needed to get the rear end loose then a quick snap of the throttle would allow the rear to walk out under full control.

Again all of this depends on the setup you are running. Any buggy or truggy can get really loose coming out of a corner. But with the proper setup the rear end will stay planted and give you the confidence to apply full power coming out of the corner.

What would you recommend adjusting to make the car more stable.

The ET is pretty stable out of the box except for a few things. One is the stock diff fluids. If you run on the west coast and the tracks have lots of sweeping turns then the diffs will be fine. But for the east coast tracks with tight 180's. You will want to drop the diffs down to 10/15/7 or even 10/15/5. I run 37.5 AE in the front and 35 in the rear with the stock ET 8x1.3 pistons. A lot of people have been running the yellow springs all around. On the front upper shocks I run the #3 hole on the tower. Stock is #4 which is laid all the way down. I did this to obtain a little more turn in with out killing much of anything in the rear.

Another item is the anti-squat. The stock setting is way too soft. I went from the 1 dot down (1 degree) to single center (2 degrees) to keep it from over squatting and taking away from initial on-power steering. On a straight-a-way with the stock 1 degree anti-squat. It made the truggy very twitchy when reaching speed.

That is pretty much it. I will also add I am running the Tekin 2000kV truggy motor. I have no timing and running the stock linear throttle profile on the RX8 and my current limiter is down around 40%.

I'm running a 1400 KV tekin motor, do you think that that may be to much speed for a truggy and cause it to spin a bit.

Are you running 5s batteries? A lot of people run the 5s on a 1400kV and have little issue with it. What is the make-up of your local tracks that you run at? And could you post a link or photo of your current setup?

The 1400kV will have a ton of bottom end grunt. But not a lot of killer top speed unless you have a fairly large pinion on the shaft.

A 1400kV motor at 21v (max charge voltage of a 5s) has a max rpm of 29,400. While the 2000kV motor at 16.8v (max charge voltage of a 4s) is 33600. You can see how much faster the 2000kV motor on 4s is over the 1400kV motor on a 5s battery. Now you have to think about torque. The 1400kV on 5s will have a boat load of torque over the 2000kV on 4s. So to tame the torque you will need to increase pinion size and also reduce your current limiter. The ET48 is very light and the drive train is very efficient for a truggy. And a lot of people look at me funny when I tell them my CL is down to 40%. The CL in the speeder is one of your best friends. And you have a couple other best friends when dealing with laying down the power with out washing out. The other two best friends between you and the motor are exponential in the transmitter and also your throttle finger.

I am a fairly aggressive driver. Coming out of the corner I tend to be heavy on the throttle with the front tires ballooned with in a couple of feet. It does make it a little harder to control than a smooth and consistent driver. Even with my being heavy on the trigger style. I never clear the apex of a corner and go from 0-25% throttle straight to 100%. It is just not needed! Roll the power on instead of stabbing the trigger. You will have better results!

The other items that cause erratic washing out of the rear-end is track conditions, setup and tires. But the info mentioned above is really the key to keeping the rear-end from wanting to over take the front end.

I'm running Austin Blair EB48 setup. I couldn't find a ET48 setup to follow so this was the setup I am running, Besides the electronics.

I'm also running the Team Trinity REVTECH Formula X 4S Li-Poly 100C battery pack. Also I like to accelerate about 40% throttle when I come out of a corner, Do you think that that might effect the way the car handles.

My friend runs the ET48 and has had issues with the diff gears. Has anyone had any problems with the diff gears?

Overall the et48 shoukd be fine for you that way. It has alot of steering coming out of the corners and the rear will rotate plenty if you just tap the gas. I am an off power type of driver so it works great. If you dont like it drop the rear camber link on the shock tower down one hole and try it again.

Have you had any issues on the center differential?
