Time for the much anticipated build of the new Serpent Spyder SRX2 2WD Buggy

As some people know I do a lot of website work for Serpent, so  I would of course get a Spyder SRX2 as soon as it was released, I and lots of other people out there have been waiting for the new buggy to arrive. I also do the mini-sites for Serpent which is the area for new cars that get released, you can see it at http://promo.serpent.com

First some Tips for you

(updated 30th October)

Please read the tips below before you build your car as there are a few things that you may or may not find helpful.

1. Always check for updated manual on the website before you begin, in the box the manual says v1 there is v2 on the website.
2. A really nice touch is all the small parts come in reusable and seal-able bags.
3. I decided in the interest of the build not to use brass bulkheads and build as standard as possible, then re build and see the difference on track.
4. Although the manual is V1 it does have step 9 – 11 in the bag as an addendum to the manual :-)
5. Also when using brown part number 500147 pivot shim conical on ball joints etc they are conical but you are not told this in the manual, so make sure you put on correctly see image below.
6. It is easy to break the plastic ball joints you could easily install the ball stud from the incorrect side of the ball joint. There are two sides to the plastic ball joint, a small side and large side so make sure you fit through the large side. So make sure you have a few ball joints in your pit box just in case.

7. Step 7 when fitting C hubs the manual is not very clear on which way round they should be as the angle of the image does not tell you, if the steering angle is not enough you need to switch left with right c hub. See image below


8. If you don’t have a 4.5mm driver a 3/16 driver or socket will just work.
9. In step 21 there is no explanation of the larger inserts and what they or how they work, also no markings on them either. The part number is 500123 used for diff height
10. I made a spring chart, if you want it just download it :-)

After driving here are a few tips

1.) Some people me included have come across a problem with the small alloy washers that space the bearings out on the steering assembly, what you need to do is replace them with the following parts from the Serpent Cobra 811 Be http://www.serpent.com/product/600180 see diagram below.



2.) When adjusting kick up, do not forget to order the matching pivot pin braces to go with the inserts

Fitting Narrow Carpet tyres to Spyder front  wheels

I recently had my first experience on carpet with the Spyder and bought some Proline carpet tyres, these are narrow fit so you need to do some wheel cutting to make them fit correctly see images below:

The build

For the most part it went really well, a few mistakes and glitches as is per normal but apart from my bad painting skills nothing too major.
The ball diff went together really nicely and easily.

The only upgrades I fitted were the aluminium Servo brackets and the carbide diff balls.
