Picture #31 shows the transponder being mounted on a more traditional location (over the steering servo). Wonder what happened to mounting it below the tank?

No need for lipo as the left/right weight distribution is good with the standard type battery in this position.
This setup may suggest the polar moment of inertia (defined by how far each part of the car is from the cg multiplied by it's weight is higher than when the battery is under the tank.
However if you take into account that the battery only moves about 20mm and most parts like the engine drivetrain and especially wheels (they have a huge influence on polar moment which is why the lightweight wheels are an advantage) the difference is minimal. And more than compensated by the lower cg.

Hope to see the car at the Mach track pretty soon.

Actually the tank is in the center of the car. Just the cutouts on the underside suggest it is offset. The lower part of the tank is shaped in such a way the fuel is very close to center even when the tank is almost empty. The transponder can go under the tank because there is a cutout in the chassis, and you must have the sump (where the pickup sits) lower than the main bod of the tank anyhow. The small amount of room left was just enough to put the transponder in.
Very good to see serpent back to the innovative part of this sport - i really hope they do well! (still some dutch love i guess??)
True comment, that's for sure.. but did you see the national class before the NT1 was there? All serpents and a few mugens.... i'd like to see more mixing too!

I had some quite nice conversation with Mr. Salven at Turkish Bumodgp. I was able to see all the 7xx prototypes ( just 2 ) in the world. He was very very nice to me and kindly answered some of my questions about the 7xx.
The car is extremely different, it does not like look like any other car or even a 720. I can easily say that Serpent gonna change the touring car scene. Lots of engineering work, brilliant ideas. It will be a giant step, believe me. The car has lots of potential.
PS: I can not talk about the details, I did not take any photos of the car ( with respect to Mr. Salven )
