Hi

I bought a second hand Losi 8ight RTR which has a 1600mah NiMH receiver pack. I'm paranoid of it going flat and having a run-away. How many tanks should I use as a rule of thumb before charging it?

I'm going to get a LiPo pack soon to replace the NiMH, how many tanks can I expect from that?

Cheers

Can't really provide a guide since the time is a function of how much current your onboard electronics use. If you have a 300inoz strg servo, you'll get a lot less time than if you're only running a 80inzo servo.

Just watch how your RC reacts after you've run several tanks. Its pretty clear when the servos start slowing down telling you the pac voltage has dropped off and its time to recharge.

Any added time from lipo rx pac will come from increased lipo capacty (mah) since these are not high drain applications. You get increased run time with lipo over NiMh when NiMh is working hard enough to get hot (heat is wasted energy) due to the amp draw and NiMh IR. Since that doesn't happen with lipo, that wasted energy translates to extra run time with lipo.
