So I decided to take my sons broken tornado and upgrade it with some top of the line stuff...

1410 3800kv Castle Motor with fan

Mamba Max Pro

3S Lipo 5500mah

Kept the same servo and radio on it for now..


Has more power than it will ever use, actually wrecked it once and tore out the front axles, new ones on the way..

But here it is...



Have an old optima chain drive, that I am going to try a little milder setup on, thats coming in the next week or so..

Speed run at the airport coming in the next week or two, will post results here.. I expect 70mph or so..

70MPH? With those tires and that motor, you'll be lucky to see 20. Are you sure you aren't overheating that motor with those tires as well??

SBS_JR

Well here is the first run on the highway, til I can get to the airport.. battery was at 11.4.. so lotsa more left.. 55mph..

Nice , well done !!!
Fully charged you might get another 5 mph out of it .
How did the tyres hold up ???
Ballooning ???
Maybe some 17mm hex adaptors and better 1/8 scale wheels/tyres for a bigger diameter .
If you up the gears , .6 mod pitch !!!
The ESC and motor have 70 mph in them , you just have to change other things to get it !!!
And watch the temps .
Just a warning .... chasing speed will limit what else the car can be used for ... you end up with a car that only does one thing - goes straight ... FAST !!!

ps ... post more pics of your speeds !!

Yep more incoming.. had to order the new steel front axles.. it is definitely slower with the 2 front axles out and a low battery.. have a front wing and mount/weight in progress to help the wheelies at 50mph lol..

And yes the tires bloom big time.. good thing they are glued well

With the mamba max pro.. complete contorl over the motor.. from traction control to limited powrr or even manually adjusting the rpm band.

This might give you some motivation .
Redcat Twister / HBX Quakewave 2WD Off Road Buggy on 4S .
6S runs coming soon ... lol

SBS_JR

Yep I know there is a ton of speed out there.. I also have a 5700 castle that I could go even higher.. think I'll need some nicer 1/8 wheels with adapters.

Before you install a front wing I have a suggestion to reduce wheelies. The guys doing speed runs with 1/8 buggies cut the angled horizontal portion of the rear wing off to reduce drag and downforce which ends up lifting the front end. They leave the vertical sides for stability. I'd try this before adding the drag of a front wing, only the 2wd guys in the speed run crowd run a front wing. Unless ultimate top speed isn't the goal and you'd rather have the downforce, up to you.

If you still have problems with high speed wheelies and the front lifting try raising the rear a little and using the lowest shock position up front. After that adjust the droop screws so the arms don't go down as much when you lift the front. No droop screws? Then some sort of limiting straps or fuel tuning inside the shocks to prevent them from extending as far will do the same thing.
