Well I have been busy building a on road killer. Here is a pic of my first attempt at painting a two tone. Notice the head lights are internal carbon fiber decals I cut from a solid sheet. 11i3bsl.webp

I've done a couple of 1/8 onroad and absolutely love the feel of driving the larger scale on-roads. The Tekno kits are definitely top notch. Here is a video showing a couple of the paint jobs I did and then running them on a 1/10 scale sized track.

 
Man that's some nice paint work. When I was looking to buy my kit I went to RC Monster forum and found mine NIB with a ton of extras for $350 shipped. He included a Ferrari 430 body untouched and Kyosho slicks mounted on Kyosho wheels. RCPD brushless set up and even a single speed. All brand new. In the end I decided to go with the 2 speed and went ahead and purchased the Tekno kit last night.
 
I did an inferno gt but prefferred the 1 speed/viscous center diff combo. Are you using mechanical or esc brakes? What gearing/top speed/runtime are you looking at? Racing or bashing? My setup was 4s 5,000mah 30c lipo, esc brakes, 13t pinion, 2650kv. I bashed so it got kinda hot after 15 minutes and had a top speed at 45mph. I though for bashing 2200kv 6s would be faster and more fun but never tried it. I like yours.
 
Stock gearing and using the 3shoe fly wheel that comes with the tekno kit. 4s 30c 5500ah. MMM 2650kv. I will be setting up mechanical brakes. I heard that the motor runs cooler when the reverse and brake are disabled. The tech at castle told me that it is true.

Yeah I totally believe you can get that speed out of it. Disabling ESC brakes/reverse, and using the 2 speed will cool it but gearing it to go 55+ Id be a surpised if you could run over 30 minutes under very hard bashing without too much heat. You will probably need to set your throttle curve so its not linear. Put a dot at 50% and drag it down so 1/2 way is only 30% power instead of 50%. And set your timing to lowest. Those 2 things will keep it cooler also, keeps the amps down on the batts, and give more run time. Get a castle blower too. don't use less than the 30c you have. Those tips were handed down to me and they work.

Good tips! The very reason I kept the 2 speed was to keep the initial amp draw on startup low but still have top end. Lots of power on tap with these setups. Check out the Kysosho GT2 I converted using a Tekno Neu 1515 3D (1360kv) motor on 6S.

that castle blower won't fit with the Tekno mount right?
 
I didnt use a Tekno kit so not sure. I really wanted to use the 2 speed w/the IGT but I like the way the car turned so much better with the center diff. That looks harder than 10th scale drifting. The blippy throttle technique sounds the same though.

Fans are a band aid fix for heat problems. There is a better solution to adding a fan. Fans break too easy and if you are counting on a fan to keep an esc from thermalling, you will have issues. a bump the wrong way puts a fan out of level. a fin can tap the housing and bam it's gone.


it is better to get capacitors, especially a 4s and up config, low emf high voltage capacitors (like the cap sold for the novak system for mt's etc) and solder across the power wires. I learned this from Brian at RC-Monster a couple years back. Dude is a tech head. I was running 4s with a plain old mamba max in my 8th scale buggy and caps soldered on. never hot, hell never even got warm, and I even made 20 min mains on one battery
