Default Need More Thrust! How?

I do want to get a "real" airplane, but I'm trying to put off buying the radio gear for a while longer. Even my HLG gear is *way* overweight by current standards.

Tried the 6-cell battery last night. A lot more power, but still not enough to fly well. Someone suggested 2-cell LiPo. 8.4V seems like a lot when it's designed to run 6.0, but the weight reduction would certainly help.

Got a lot of reccomendations from indoor fliers here to cut out weight through better batteries, motors, and wing. Seems like good advice, and I expect batteries and motors are a good investment that would outlast the relatively disposable plane.

Question on LiPo: Discharge voltage is 3.0 per cell, right? so I'd need to be careful not to let a 2-cell pack drop below 6.0V lest I destroy the battery. (And that could be very dangerous as well as expensive from what I've read, right?)

Since the design battery is 5cell NiMH, I expect the motor cutout is at 5V.. too low. (Not that it flies at that voltage..)
