Picked mine up yesterday!!! Now I just need some time to assemble it . It's my first 1/8th scale and I'm excited to drive it.

I pulled the front sway bar off and also went with 35wt shock oil up front (grey springs) along with removing some bump out and found the steering I was looking for.

Is a 3mm hex driver necessary for the build? I thought I read that one was necessary and ordered one but I see it's not listed on the tool list. I'd rather not buy it if I'm never going to use it.

This is what tekno lists from the manual:

Tools needed:
• Hex drivers 1.5mm (TKR1104), 2.0mm (TKR1105), 2.5mm (TKR1106)
• Nut drivers 5.0mm (TKR1107, 5.5mm (TKR1108), 7.0mm (TKR1109)
• Hobby knife
• Needle-nose pliers
• Shock tool (TKR1115) OR adjustable (Crescent) wrench (for shock assembly)
• 17mm Wheel Wrench (TKR1116)
• 4mm turnbuckle wrench (TKR1103) - 5.5/7.0 two sided wrench (TKR1119)
• 4mm arm reamer (or #19 drill bit)

So I am thinking thats all you need. They also don't make a 3mm hex driver from what I am seeing either, I would think they would if their vehicle needed it.

i can't remember the size exactly but i think its a 5/32" chainsaw file and it works perfect for reaming the arms.

i couldn't justify an arm reamer compared to the cost of a file, when the file is just as good if not better, much more consistent, IMHO.

I tried a Lutz base med to low grip rough track setup and was pushing on power, i think i had too much rear grip im gonna try the grey front red rear springs with 3x2.1 pistons this week. Other than that the buggy was really smooth and easy to drive hard.

Just built mine over the weekend and my ET48.3 about a month ago. Never found I needed a 7mm turn buckle wrench. I just have the 4/5.5. What is the 7mm end used for?

Season has begun here! Was able to drive my .4 for the first time and i am very impressed. I've had the .2 and .3 Buggy's and must say that this new .4 is by far the best! IMO. It is smooth from the start, enters corners and exits with power and stability. I am running stock setup right now and its pretty close to what i like. Steering is awesome. Has anyone else started racing? What are your thoughts?

About to start my build as soon as the mail arrives. Nice to hear it handles good with the box setup.

Ran my .4 for the second weekend last weekend. 2nd track too. I needed a little more front steering, so dropped the front ride height 2mm compared to what I was running, and the car felt very good. Car was very good.

I ended up qualifying 8th in the B main, with mains down to E. I'd also finished there after making it up to 4th, and made a couple mistakes, dropped to 12th, and fought back up. The car was easy to drive the way I have it setup.

Outdoor season is getting closer. I had to drive 4 hours for this outdoor season opener at RC Madness in Connecticut.

I'm running a slightly modified setup of the recommended tekno setup, I never tried the box setup.

Mine arrives today (I'll "race" you, Derrick!). I went racing over the weekend and noticed a couple .4's on the track in the ebuggy classes... they looked smoooooooth!

I will say this though. No new kit will help resolve a racers lack of setup knowledge. Work with you car, change a setting, and go out, and see what it does differently. You cannot go chasing pro setups.

For instance, last weekend my buddy and I swapped cars while on the stand. His .3, and my .4... Both cars drove the same, literally! (incedentally, both MT4s radio's) Within a lap we were both able to just go burn laps, as the other car felt good. That being said, he has a full season on his car, and working at it. My car wasn't what I needed when I showed up to the track, but with a couple changes, it felt good. This car is very responsive to changes, just like the .3 was.

But at the end of the day, I feel with time I can make this car feel better everyplace.

Yeah, I am going to drop the front a mm or two for more steering on power/cornering, go down to 400PT oil in the rear to compensate for 2 big jumps on my track. Other than that i am very pleased.

Awesome! I am going to drop the front of mine as well. Sounds great man.

any picture of painted bodies ?
