OVA, I thought the same thing about all the moving parts but after driving my car a few times I could see that it was actually very durable. The only issue I had was with the front belt popping off. I think it was because I didn't run the front brace....

I have a question for you...I know there is a damper the move side to side..do you have to change the oil to slow the side motion or the mono shock slow it down?
thanks

You will have to contact site admin for that, I don't know any more than you do.

You can use thicker oil to slow the action or change for harder springs for more roll stiffness in the roll damper. Quite revolutionary IMO.

That's was I thought ...So you have to take those damper assy part out to change the oil thickness every time when the track grip is high or low and hopefully those damper last a long time before need for rebuilt.....

You do - but the car is actually very easy to work on, despite it's overengineered look.

For roll damper, it's actually designed so that it can be dropped in/out so it should be straight forward enough (when the spares become more available) to build sets of not only roll dampers but heave dampers with different oil thicknesses and springs in them that can be changed WAY more quickly than a spring or roll bar change on a more conventional chassis.

So far dampers are looking good!!

I did also forget to mention that Serpent do provide different pistons for the roll and heave dampers, blank, single and double holes but all setups so far seem to use the default single hole.

I've only had one outing with mine, and it was pretty good constidering that I had no parts or spring options. The first thing that I noticed was that the car carried a lot of speed throught the corners. Durability seemed to be on par. Having been out of electric TC for about 1 1/2 years, I was able to take third place in a double A-main (one second,one third) event against some pretty good competition. Only gripe was that it was a little chubby in respects to ROAR's new lower min. weight. Since then, I have replaced most of the screws with Ti and aluminium. As of now, I'm sitting at 1357g

Drove one yesterday for a pack and was impressed with the car. Stock setup seems like it's only a couple of adjustments from being perfect but still very easy to drive and very predictable. I have decided to sell off my A800 to get me one of these now so looking forward to when I can get one on the track. Good work serpent , make a truly different car and actually have it work is impressive. At least in today's standards.
