ZTW Spider 18a Lite vs KISS ESC
With DYS/RCTimer SN20a and BL20a possibly having a bad manufacturing batch. Plus, you lose about 10% thrust versus competiting ESC. One of the new ESC some of us have started buying instead are the ZTW Spider 18a Opto Lite as some retailers are calling them. Performance seems good so far. We’ll learn how their fare in crashes and general abuse as more and more people use them and report back.
The BLHeli firmware to use are BS12a or BS20a. either hex will work fine according to sskaug (Steffen), BLHeli creator.
Mine came with the SimonK bootloader. And I was able to use my USBASP to flash BLHeli bootloader on there. Here are the ISP pad locations for your reference:
Weight as they come out of the package. I took off the heatshrink and it was about .2g lighter.
Heatshrink is thin, clear and shiny. Same types they use on many battery packs.
Weight of the naked ESC.
Here’s a shot of the ZTW Spider Lite on the far right. Next to it is the new KISS 30a. And to the far left, is the KISS 18a.
Picture of the MOSFETs and a peek at the soldering. I don’t see any left over solder splashes/balls.
KISS 18a on the left. ZTW Spider 18a Lite on the right side.
Side by side with the KISS 18a v1.1. Which is simply about 1mm longer than KISS 18a v1.0. You can see that the ZTW Spider 18a is slight shorter. And also thinner.
A look at the opposite side.
Here’s the Spider 18a Lite mounted in the lower plate of the Aura 250 FPV quad.
And a couple of closing shots of the Aura 250.
I modified the top plate so I can slide in a 4S 1400mAh lipo pack.
