Look at nimhs, IB4200s had a small performance advantage over other makes, even though they had the lifespan of a mayfly, yet everyone used them and they gave all nimhs a bad reputation. Now they have been banned due to being oversize  racers are finding there are better 4600mah alternatives that don't need constant maintenance, hold their charge, and are as reliable as 3300s used to be. |
On the money mate!!
My E4500 packs haven't been touched for 2 weeks and only took 600mAhs this evening to peak (storage charge check) and before that they had gone 2 months without dropping much.
Playing devils advocate here,
assuming there are packs available that fit the dimentions quoted in the rules what is the problem?
Surely you either buy those packs, a car that takes sticks (ZX5-SP / Cat SX / Durga probably others), or run NiMhs.
How is this different from this year where we had to buy new cells in order to do the nationals if we had IB4200s? My IBs were only 4 months old and still going strong but I wanted to race at the nationals so bought E4500s as did many, many others!
I am hoping that somebody comes on here and explains why the dimension thing is a problem as I really don't understand!!
Sub C-cells are 23mm dia. so that only leaves 1mm for second heatshrink and glue to be inside the 139mm length! To me the regs read as follows
"LiPo packs have to fit into a car designed to run with the current norm of 6 sub-c cells so nobody has to buy a new car just to run the LiPos"
Have I intepreted the dimention rules incorrectly???
I understand why people who have the trakpower saddles feel a little hard done buy but I really can not see any difference to those people who had to buy new cells around Xmas07 or not race for 4 months until the 08 cells were legal!!!
