My Tekno ET48.3 Build - 03.25.2017, 05:34 PM

Hi there,

Good to be back at RC Monster I am Flo from Hamburg and I am RC-infected for about 10 years now.
I have done several 1:8 electric conversions and builds, this is actually my second build without converting a gas car into electric, it's "just a build".

I will also post some inside-view pics of the Medusa Afterbuerner brushless motor (probably including some nude hands...)

It took me a while to find the right setup for the truggy, now I am quite happy with the ET48.3. I like a soft setup, and I have installed the CS shock plates. The overall-quality of the Tekno is ok, the transmission, diffs have excellent quality, almost no wear so far.

I own the ET48 for about 1,5 years now, and lately have serviced the truggy (cleaning, new bearings etc.).
The body is new an got damaged already, fixed it with a 2 component glue (ZAP z-poxy quick shot). So far the poorest quality in regards to body shell.
I also cleaned the new bearings and oiled (special mixture) them, to avoid dirt sticking on them.

I changed the rear arms, as one arm has cracked again, number 4 so far. They always broke during "normal" driving.

For the rear end I made a skid-plate from epoxy/glass fiber composite, which is very durable. To avoid sand and dirt between the chassis and the skid plate, I have glued it on the chassis with car-silicone.

In the front I have used kydex. Kydex is very rugged an can be bent under heat. I use Kydex for many years now, initially I have made battery-cases with Kydex. Simple, cheap and durable.

new body:

As I had birthday recently, I have got myself a new motor, a 3680 Medusa Afterburner with 1600 kv. That's why I had to move the ESC backwards.

To stay cool I have glued a 12v fan on the chassis, which runs on 5s.

The new HV-Servo (Turnigy) has 21 kg torque, 0,16 speed (a bit slow). The servo horn I have found at egay, is kinda low-profile, and fits quite well.
As my RX receiver only works with max. 6,5V, I have installed the new HV UBEC just for the servo, with 16 AWG wires (!).

The capacitor-bank for the ESC is from a dead skyrc-ESC. The servo has a big fat capacitor to stay powerful. The wiring is as clean as I am able to...

to be continued in a minute...
