2 cell Lithium polymers as your receiver pack?

[Atwood, Mark]

Same stuff...a couple of foamies (Yak) and a Vertical R/C Katana.  All with Hacker 20-26s and 3cell LiPo's...Great for messing around in the front yard or at the park.  Oh...and an IFO with a cheap 280.  AWESOME on 3cell LiPo's...for about 2.5 minutes...then the motor smokes :)

 I have the Li-ions for my pattern planes now and I now have the Triton charger which I'm using for a foamie 3DX with a li poly pack so it got me thinking that the li polys would be the thing to go to. I wonder how many flights you could go on the Li polys in place of Ni cads. I'm not saying that I will be doing it just getting feedback and formulating an opinion. I agree that the Ni cads are a no brainer but I like the extra power of the litiums and I think i want to stick with them. What kind of E planes are you doing Mark? Mike

I'll still ask though if there's really a need?? I LOVE the LiPo's for my electrics...huge run time, and low weight.

But for most of my glow and gas stuff...the weight just isn't an issue. Certainly not a big enough issue to warrent the potential headaches and cost. For ME...huge caveat there...for me Nicads are just too easy. You can abuse the crap out of them, charge them with just about anything including a squirrel in a treadwheel, at any rate, and they cycle 1000 times or more...no exaggeration...and keep ticking. Not to mention there available anywhere dirt cheap.

That doesn't answer ANY of your questions...ahhhh..but I feel better :)

Mark I was referring to a receiver pack. Am I missing something here? Thanks, Mike

The nicads are 1/4 the price, last 10X the cycles and are a known quantity regarding charging, fast charging, etc.

The ONLY advantage is weight and size. The Tx isn't getting any smaller, and I'm already using a neck strap...sooooo...what's the point?

Ok this has probably been discused but I never payed attention till now. My question is can you use Li-poly's instead of Li ion's or nicads? Would the regulators have to be different? What about regulators over heating? How long would a 2 cell 1200 Li poly pack last before needing a charge? Is this the way were headed? Thanks, Mike
