Hi guys.
I have been looking at this car hard. any word as how this car has been doing and holding up?
If I got this car for store parking lot running what tires would you recommend?

Upgrades? None. Running box stock, just fine.
That is, if you're fine with running full size 2s Lipos. I was not, I wanted to run shorties, so I had to make my own carbon fiber plates as replacement for the front stock carbon plates of the battery holders. Some 2mm plastic works as well, but just doesn't look so nice in the otherwise carbon car.![Smilie](https://www.rctech.net/forum/classic_images/smilies/smile.gif)
Gearing:
Runnning a 1900kV Hobbywing motor with 4s batteries and Hobbywing XR8 Plus. This combo runs really cool. Rollout is 53mm on a smallish track, i.e. smaller than the typical large Eurpean 1/8 scale tracks. 40x10mm fan on the motor with duct, temps well below 60 deg. after 6 minutes runtime at around 20 deg ambient. No openings in the body for cooling (yet). Not sure if I will even need them, come hotter weather. So far I'm optimistic that it might work like this even at around 30 deg. ambient.
53mm rollout is with 70mm rear tires and 58/14 gearing. I assume a larger rollout would be possible on larger tracks with less tight turns and a more flowing track layout, i.e. less need for hard acceleration from low to high speed and for braking vice versa.
Serpent only offers spurs up to 58t, which is not enough for me if I want to run larger tires, on the smallish track. For 75mm rear diameter tires I have a 62t spur from the Shepherd Velox V8 (part number 604162). It requires some dremelling to make the screws go deep enough into the spur holder, but the inner hole diameter for the axle as well as the diameter of the 3 screws are a perfect fit, no play, no binding.
I only found pinions with 14t or more with M0.8, so I needed larger spurs. All I need to cover the usable rear tire diameter range from 75mm down to around 66mm are pinions 14/15/16t and spurs 62/60/58t. If you can find smaller pinions with 12t or 13t you may be able to live with the Serpent spurs with 56/57/58t. But then again, that depends on the size of the track you want to run the car on.
58/13 combination fits no problem with sufficient space between motor and rear axle. Only I can't run the 13t pinion because it was not milled properly and doesn't mesh well with the spur. Duh.![Frown](https://www.rctech.net/forum/classic_images/smilies/frown.gif)
I have not tried 58/12.

Just make sure you don't have any bumps, the surface should be really smooth, otherwise the front may bottom out and you'll quickly scratch the chassis.
Can't say anything yet about durability. The car drives so well, so easy, turns on a dime...so no crashes yet.

Hobbywing XR8SCT should work as well instead of the XR8 Plus. It’s a little cheaper and can‘t handle as much current, but should work with the 1900kV motor. The XR8 Plus may be useful if you want to run faster motors than 1900kV at some point.
All 1/8 nitro onroad bodies fit on the Taipan.
I am using Xtreme Diablo, Blitz TS040, Blitz TS050.

Here's my ESC setup.
(I am using shorty batteries and had to modify the car to make that work. See above for details.)

Here's a pic of the modified battery holders. I created two custom carbon fiber plates as replacements for the original ones provided by Serpent.
It's not beautiful, but it works.![Nodding](https://www.rctech.net/forum/classic_images/smilies/nod.gif)

Working on a suspension upgrade for the Taipan.

Edit:

I looked at the picture again and I think I found the answer to my own question, so I edited my previous post.
If I am seeing this right you removed the spring effect of the carbon plate by removing the middle bar in the carbon plate, thus disconnecting the left from the right side of the carbon plate. That of course would provide you the benefit of tuning the spring effect to your liking, which is not possible with the stock setup and the fixed spring rate of the carbon plate. Correct?
