i didnt give a report these last few months becuase the performance of the team drivers 4200mah saddle pack leaves much to be desired. Just bought a IP5200mah 45C saddle pack and its much much better. battery weight is 280g.
i also modified my kawada sv-10 alcyon2 EX into a alcyon 2 Ultimate, by removing the normal side top decks and replacing them with the Ultimate side top decks. this has the advantage of freeing up space in the middle of the car, as well as allowing the chassis to flex like all other cars. It also allows the batteries to be placed more forward. Becuase of this i had to flip the servo and shift the ESC forward. with the batteries on now, i have 50 - 50 front rear weight bias. of course with saddle pack cars, the L-R balance is always GOOD. previously the F-R weight balance was 53% rear, which translates to 60g heavier at the back ! this is a common problem for MANY Saddle pack cars back in the day.
as you can see rear shocks are stood up very straight to give better response. since it is this straight, i had to compensate by using softer springs, with 196g/mm force,to get the traction. i also installed the thickest antiroll bar at the back becuase the spring is so soft.
front shocks also stood up to the max for faster steering. Yokomo pink springs with 300g/mm force, and medium antiroll bars. the front shocks feel much harder than the rears.
Front and rear ball diffs. Sorex 40Rs.
the IP 5200s are placed at the edge of the chassis (108mm) wide.
now i do not have problems fitting ANY lipo battery in this car. Tested at a very large track, titiwangsa track in kuala lumpur. keep in mind the car is a saddle pack car that was obsolete as of december 2002. Using a HW 2.1 120A ESC and Team powers 10.5t motor, with turbo and boost activated, the car is extremely stable even at its blistering top speed, which was fast enough to overtake a 1/10 GP car in its second gear ! My SP car never showed any signs of sliding in the rear either off power or on power. if you took the corner too fast it would push, but even modern cars do that. braking was very stable and once slowed down enough could negotiate the 180 u turns with ease and contniuos turns were a easy too with partial throttle. The car was on rails ! proof that the saddle pack layout does work.
there is definetly benefits to having the motor in the center of the car with a marginally higher CG.
