OK, so after last weeks nightmarish runaway and impact I am upgrading all the electronics in my buggy before I use her again. Starting with a receiver pack and a failsafe. Then a transmitter pack for my Airtronics MX-3 Can you guys tell me the difference in runtime between lets say an 1100 mah 5cell 6 volt receiver pack and a 1600mah? Should I care? The hobby shops in my area dont carry... ANYTHING so I have been perusing ebay. Lots of options. OFNA's, HPI, TRINITY, RACERS EDGE, POWERIZER, ORION, no namers etc. Additionally is there a better fail safe to buy over another? OFNA, VENOM, DURA-TRAX etc... THANKS!
