RE: discharge rate question- help

Higher "C" ratings equate to higher power (current draw) without making 'tacos' out of your batts.
1800ma @ 10C = 18A - - @ 20C = 36A - - @30C = 54A
For a 4-cell LiPo that means 266.4 watts for a...

RE: Question about Lipo disposal

If they're bad, observe on a safe surface at a distance for ~ 30 minutes, discharge and toss - no special handling required AFAIK.
Your safety officer should follow-up with who's discarding them...

RE: ESC question!!!

40A vs 60A ESC should make little difference other than additional weight, but 60A will give a bigger margin of safety if you play on flying it on the edge.

RE: Wire Size/Type from ESC to Batteries

I've never had and esc fail (from spikes, even with long leads) either, just wondering about the theory.
Not sure an electrolytic would provide "spike" attenuation once charged.

RE: Wire Size/Type from ESC to Batteries

How large are these spikes? Thinking large ceramic or tantalum caps across the battery leads would limit them sufficiently enough
to eliminate damage. (?)

RE: Cant find any ten pound electric planes.

If the motor and ESC you have will handle 10-12 cells - I bet that Super Cub would fly just fine !!

RE: Buyer beware Hobby Lobby and customer service

I have a dislike for most of the ARF stuff from China, it just ain't done right. The AT-6 Texan is a perfect example, but it appears Rachel made a decision based on your own admission (unfortunately)...

RE: Cant find any ten pound electric planes.

You're looking at some pretty big planes <g> if you want 10# empty (?). Batteries for that size will easily run another 2# - probably more. I fly a couple larger TopFlite models with outrunners on...

RE: New Lipo battery problem

3V/cell is inviting disaster. LiPo batteries are generally void of any useful charge at 3.6V/cell. To promote battery longivity, most use the 80%
discharge rule which is about 3.75V per cell.

RE: Lipo charge & discharge?

Your charge calc is correct. The 3.8v/cell limit is well advised but is closer to 30%.
4.20v = 100%
4.03v = 76%
3.86v = 52%
3.83v = 42%
3.79v = 30%
3.70v = 11%
3.6v = 0% (probably...

Many to choose from, the Accucel-6 or 8 should fill the ticket.

RE: 80A ESC w/BEC - Can't find them!

AR500 is rated 3.5-9.6v - perhaps a 2-cell Lipo to save weight. Size (ma) depends on current draw of servos and accessories if any.

All my mid-size planks use Turnigy Plush 80A esc w/bec - 300+...
