I just bought two (max amps) 6 cell NIMH 1600mAh saddle packs (have been using stick packs) and was wondering whats the beest way to mount them on my front axle? Is the battery servo tray work well with saddle packs? or should I just mount them on the axle with out any kind of plate? I do NOT want to use zip ties since I have two of these and will need to swap them out and will be using the velcro straps that come with the crawler. Please post pictures thanks!
