out of the 3, the b44 and d4 are getting on abit, the rango has just been updated and was a very good car anyway, also consider the schumacher sx3 as a good car,
the sphere may be stretched abit running a 6.5t in a 4wd as they do draw alot more power than 2wd's
Also dont forget some chassis only use certain battery types, think the 3 you mentioned are all saddle whereas the sx3 can use saddle and stick,
im waiting for losi to bring out a new 4wd though as become a big faqn of theirs now
