That was an improvement. Then I switched to lipo in both - I've been using 3S 3300mah lipos in each for almost 3yrs. That change was also a big improvement, not only in how long they last between charges, but in the weight reduction as well since lipo is much lighter than the nimh packs.

I have a few 4 AA cell type 2.4 rtr radios too. Those I use the low self discharge rechargeable AAs in them and as my older ordinary rechargeable NiMh AAs wear out, they'll be replaced with the LSD types.

I'm building an 8 cell LSD pac fopr my Futaba 7C heli controller since the orig is another 600mah Nixx type pack. These LSDs are a big improvement over ordinary rechargeables.
