Looking good. Bummer about your ESC. Do you have any plans to finish/paint the aluminum?

I was thinking of leaving it as is or brushing it.

I am waiting so bad for the new esc and motor :) Right now I am running on 3s
I got a top speed of 58km/h with 11/48 gearing.

Now I know when to calculate for top speed to use 3,7volts instead of 4,2.

The calc gives 57,8 km/h on 3,7v and 11/48 gearing
So its pretty *censored* accurate like this.
But ofcourse if the speed increases the drag increases and it will not be as accurate.

Shock protectors are working incredibly well. I filpped the truck at 60-70km/h on asphalt.Lots of sparks but the shocks are fine.
Recieved the Hobbking ESC now. Stays cool with 9/48 gearing and trenchers. Only thing I don't like is that it jerks when taking off from a standstill. But It was only 50$ and it seems to handle high currents better than the orignal blur.

Also It is HUGE. I had to relocate it. Now it is under the roof.


This thing is so fun to drive on loose gravel. Cannot compare it to stock without CD. It drifts instead of lifting the front up. I will get a video soon.

Tried some speed runs today. Got to 104.5 km/h with stock motor and it was barely warm.

17/48 gearing and vorza tyres.

Will try 20 and 25 pinion tomorrow to see if I can hit 110.

I have the Leopard 4092 1300kv but I don't have gears to gear it that high. Tried with Trenchers but those are not good for high speeds :)

Did some more speed runs today. Best I got was 113km/h and that was after about 10 speed runs so the batteries were not full.

Gearing was 20/48 Will hook up 2 extra batteries parallel that and 25t pinion should get me to 120km/h

This is my attempt of making it more aerodynamic. Will try with the same setup and see if it made it better or worse.

My attempt made it act like a plane :) At 98km/h the front lifted and I crashed into a curb. But everything else is fine exept the aluminum casing.

Your gearing was 20/48 on 6s and you pulled off 113kmh(70mph)? Sick  :twisted:

How hot was the motor and esc after the pass?

I am trying to reach 140kmh. 130 is very possible because 125 came with only a second or two on full throttle.

The hardest part is controlling it on high speeds. Maybe that is because of the worn out ballooning vorza tyres.

I will get the xo-1 ones soon then will try to get some better runs.

I can help you go even faster if your willing to make some changes to your setup. Plus I wouldn't buy the X0-1 tires. Unless you can get them up to a temp over 119F there slippery and even harder to drive. Instead look for some 35 or 40 shore 1/8 foams.

I've reached 175kmh(108mph) at the moment with my truck.

Unfortunately I have already ordered the xo1 tyres. Will use them as long as they will last.
After that I'm going to try the foams. They must be quite a bite lighter aswell?

I could however use some help with the steering. Do you use the stock steering rack and servo?

There is alot of play in mine and the servo will not center. So I constantly have to correct the steering.

I am not going to reach those speeds :)
After I am done with the tork I will try leopard 4092(1390kv) on 9s and try to get to 150kmh.

There not bad tires at all, just need heat to perform their best.

Steering, I use a stock bellcrank with Lunsford tie rods w/traxxas rod ends. I also use hellfire hubs and blocks BUT they will only work for RWD. To go faster and yet remain in control you need castor. The more the better. I would source out an hpi suspension kit. It adds 10deg of castor to the front and you can still keep the truck 4WD. The link between your servo horn and bellcrank, I use two small 3mm alloy shock rod ends and thread them together with a 3mm screw with the head cut off. I would also buy some 8mm diameter shims to put on the drive cups. This will eliminate the wheel slop. The key to keeping it straight is keeping everything tight. Some will tell you to add expo which lessens the input on the steering. Meaning a small touch of the wheel doesn't translate into a normal turn on the truck. You'll have to turn the wheel more to get movement out of the truck. Also your turning radius will be huge. I don't run any expo. I learned to drive my trucks without it and I have developed a feel for the trucks. If you have your steering perfect you don't need expo IMO. So try the suggestions and see if they work for ya. If you can't find parts I'm suggesting let me know.

Oh and don't freak out if you crash, it's a by product of going fast and learning to control these buggers at stupid speeds.

Thanks for all the info!

I have read up on castor and it seems very beneficial for straight line stability. But I could not find any blocks that would work. The Hpi suspension kit is 170$ and I couldn't find the blocks separately.

Right now there is about 2-3mm slop in the steering. I will try replacing the links and ball joints with the ones you suggested.

I noticed that my rear hub carriers have a pretty big negative camber in the middle mounting position when the truck is lowered down. But when I use the outer mounting position it is pos camber.
So maybe I should get adjustable upper arms to limit the drag and tire wear.

Don't forget the shims. The shims I'm talking about are the same ones as the 8mm shim on the diffs.

As for the castor blocks I did come up with a way of adding more caster to the stock setup.

Pretty much you shave the ends down at angle of choice and drill a hole through the cut sides then slide the block onto the arm. Pretty easy and I would have used this on my twin but found the hellfire instead.

If you buy aluminum hub carriers and mod them for more castor like LL did, they will hold up IMHO

I already had the axles shimmed from the beginning. The wheels were terribly wobbly since new.

I actually thought about this today but I thought I can't make two sides exactly the same and that would make things even worse.

Have you tested this? If you have then I might go down this route.
