I finally dug out my Hobbico trainer, and Super Sportster.

Both have OLD NICD rx batteries, and I know both need to be replaced before I start flying.

I have been looking at lipo rx batteries on the market. Do a lot of people run these, or should I just keep it simple a buy a new NIMH battery?

If I do run lipo, can you wrap the battery in foam to protect it from vibration. Like I did with my NICD. I know lipo's will get hot when used on electric planes. But with the low draw of power as a rx battery, will it still run hot?

Also I finally made the switch to spektrum. What RX should I use for .40 size planes?

Thank you.
