Hi,
Are the Zippy Compact lipos ok as my Thunderpowers don't last too long as they do get a "hammering" in a heavy plane...70oz.
Also, I don't treat them very nice as I charge them when I come home from flying and then they stay charged till I fly next, usually the next week.
If I use the Zippys, I can conserve the TPs for competitions.

You wrote "Also, I don't treat them very nice as I charge them when I come home from flying and then they stay charged till I fly next".  You do not want to store you LiPo batteries fully charged, this will shorten their life.  The rule of thumb is store them with a charge between 20% and 50% in a cool dry place.  I have used Zippy batteries and they last as long as any of the other sport batteries I have used.  Again do not store them fully charged.

Russel, I've recently been hamming the living daylights out of a bunch of 3300 6s packs for my f3a model. I'm running 2 packs in parrallel and consistently pulling over 100 amps with the setup (Low voltage, high amperage).

They do come out looking a little puffed but after 20 or so cycles of this abuse they're no worse for wear.

I am however swapping out that setup for an 8s one, running such high amperages to get the wattage is a bit rich for my taste.

I've used the NTM motors for stuff that I don't really care to much about. They're cheap motors and are used as such.

I'm planning on using an NTM 35 36A on 4s in a 35 sized model soon, will report back on how that goes.
