ZZ SE Crusher

[k_manNZ]

Ok, maybe this belongs in another catagory but it was when I got my SEs that inspired me to put this together.

This forum was very helpful when trying to fix my steering problems. No chance of returning as they were from eBay. No local suppliers in Zew Zealand you know

Apologies if this is a bit pic heavy.

I like my tanks.
I like proportional.
I was outta luck.

I wanted to drive over my SEs with something that was close in proportion.

In short
1. Select scale
2. Fit electronics
3. Drive

First step what was the proportion of the ZZ?
Lenght between 1/62 - 1/64 depending on model of body used.
Height 1/43 - 1/44.
Since I wanted to drive over them I had to go with height scale, 1/48 (closest model scale).

RC tanks are available from 1/72 upwards.
1/72 was a bit small



Next, get the bits inside.
Reciever, you stock 2 channel Futaba RX.
2x Mtroniks Reverse ESC. Good to down to 14 turns 160Amps.
Overkill I know but I had them and they were smallish.
Batteries


A collage of the build process.
Removing the electronics from their shells.
Grinding off the excess heatsink from the ESC.
Getting batteries for the RX from a 9v 200mAh NiMH battery.
Not what I was expecting inside the battery.
Looks like AAAA
The ESC can switch 2.4v while the RX needs 4.8.
The motors that came with the model were designed to run on 2.4
Fitting the radio tp the turrent of the tank
One stick on the remote was rotated so I had two vertical controls
Almost done


To do.
Add some lights

How does it go?
On 2 cells pretty slow. 4cells, now we're cooking. The motors probably won't last long on this though.
normally when a tank runs over a car it collapses. These dont, the first time I tried it just rolled the zz then flipped itself.

I could have saved myself a lot of time and money and bought a premade unit. us$50
This one cost
$20 Model+ $40 Radio+ $80 ESCs+ about 8 hrs to put it all together
Since this is standard 1/10 radio I have access to all their frequencies and not just the 27/47 etc of the all in one RCs.

thanks for reading

looks pretty sweet... the price is steep but i'm sure that building it yourself you know exactly what you're getting... and that is sometimes quite a mystery is RCs these days.

Thanks Twenty-Se7en

yea it was on the expensive side.
I tried using a Futaba S3003 servo.
They can be modded into a speed control.
But it started smoking after running the supplied tank motors.
I could have modded the gearbox to take the servo motor but it seemed easier to use the esc at the time.

Oh well, if I decide to put in a 14 turn 540 motor it should take it

I wonder if the ZZ SE pcb can be modded to pass 1 amp.
Of course I would be hogging up 2 channels.

I wouldn't really know about that stuff too much but i'm pretty sure that you could do it... quite the electronics in that rig. Only freaks like us on this forum can apreciate this though... I can imagine trying to explain this to my better-half and getting a dumbfounded look followed by a "that's great dear" lol
