I just got the new super nova comp during last week and used it for the first time over the week end at the Off road Vic titles (Australia).
I used book settings (4-step) to charge my year old Kinetix gp3300's in stock 2 and 4wd , took TQ in 4wd and 3rd in 2wd, I lost TQ in 2wd by 2 sec.
So yes I think the new method of charging has helped.
After 8 months of no use of these batts, or 2 years of using my 4wd I think this is a good showing of the new charge methods.
No matter how fast you are or think you are... Remember you were new to RC once, so help out where you can.
Everyone has to start somewhere.
