I dont have much experience with mini or mardaves but they do look good, especially the caterhams. I do have some experience running with 4 cell batteries though, about 4 years ago I used to run one of these:

Running it with 4 cell nimh and a 4.5 novak brushless. While it wasnt the fastest thing out there it was definitely one of the most fun forms of racing. Its a shame it didnt stay around
Both the minis and the mardaves look like a great little form of racing! So even though I wont be running one they do get my vote! If anyone is interested I found this review of a mardave caterham:

Paul, from the review I have a few questions. Is your mardave chassis plate countersunk underneath? As the review recommends doing it if you are not running in the BRCA championships. Also have you tried "water dipping" or spraying WD40 on your motor for improved performance?
I still have one of my Xray 1/12th touring cars if anyone is interested in seeing it, I will bring it along one friday
(not that I am saying we should allow them to run, its just nice to old past cars
)
