My EXPENSIVE list of Bl-lipo items

This is what is going onto my maxx. Please tell me if something is wrong, or does not match up. And what gearing I should run (with a mod 1 51t strobe spur)


-BK 20150---$500

-BK wanderer 10xl (or lehner equivelent, which ever one that is)---$100

-Two Maxamps 3s2p (4000mah lipo cells from maxamps) lipo packs------- $500

-Maxamps 2s2p 7.4v 3000mah reciever pack made with 1500mah lipo cells from maxamps (no ubec b/c i'm running 1 airtronics 358 (200oz) servo and two 357 (.07 sec) servos, two fans, and the esc)---------$60

-Reciever pack converter: http://www2.towerhobbies.com/cgi-bin...?&I=LXJJF6&P=7 -----------$20

-I don't know what it is, and I don't know if I need it, but someone recommended it for my reciever...

-2 (if necessary?) Maxamps Hyperion EOS5i Charger---$85 each, $170 total

-5mm gold everywhere (except reciever wiring)

Total: $1356 -WOW-:007:

I can't think of anything else, but if there is, tell me. I'm mostly worried about if I have everything I need for my lipo (eg. voltage regulator and that other junk i need).

or for a charger i can use http://www.finedesignrc.com/battcharge.asp
the ASTRO 109 lithium charger.

Btw, how long will it take this charger (or the one up above) to charge my 3s2p 8000mah battery pack?

[squeeforever]

a 3s pack charging at 1C (8 amps) it would take one hour. that would be a reason to go with the astroflight because it can charge at a hgiher amperage than most hower i would sugest the schulze 330d or the mrc 989.

Why are you buying the 20150? You can get for the same price the 36150?

[maxxdude1234]

36120 will be a MUCH better choice for that motor. There is no need to have a 150amp controller with that motor, but the ability to handle extra cells might be useful for the future.

That's just a capacitor. It is supposed to smoothen any voltage sags when the load (servos) start pulling some current and might help with noise. However, the value is really too small to do any good. Plus, you are running a receiver pack that should easily drive those servos. If you were running low power (under 800mAh) cells with several (at least 5) servos running at the same time, then it might help to keep the voltage up...maybe. Your Lipo Rx pack will be more than sufficient by itself... and even if the voltage did drop slightly under load, you won't even notice it because of that receiver pack converter (which is just a 6v regulator).

Good luck with the rest of your selections!

All I can say is that you are going to have some MASSIVE runtime. Just make sure to get some taps and a balancer for those batteries!

For a charger, you could check out the Super Brain 989. It's supposed to charge up to 8s Lipo. The only thing I'd be worried about with this charger is how many amps it can do with 6s Lipo.

i may have missed but you need to get a LVC for those lipos that thing is going to run forever

whats an lvc?

What are taps and balancers?

I will not be upgrading my voltage in the future, 22.2 volts is plenty! So should I go with a 20120 or 12020?

Will it be any "safer" to just go with a 20150, or is there absolutly no chance a 10xl will get to that amperage?

What speeds will I be looking at? Should I move down to a 9xl for more speed, or is a 10xl good?

Anyone have a KV chart for wanderer motors?


EDIT: I found a hacker B50 chart, which should be the same as the wanderer (+- a few kv, but whatever). My old setup, 8xl on 16 (19.2v) cells got 37881.6 rpm and my new setup, 22.2v on 10xl will only get 35031.6 rpms. So it will be considerably slower, but will I be able to make up the difference in pinion size (say 24 tooth pinion, 51 tooth spur). Or should I go with the 9xl, which will bring me to 38916.6? Should I email rcmonster on this? Thanks.

[squeeforever]

i think you will be happy with the 10xl. to be honest the 12020 is overkill also. the 10xl would actually be safe to run on a 7020 with the proper gearing. i would just go with the 9920. also, the 10xl has a kv of around 1650 rpm/volt unloaded.

DON'T GET MAXXAMPS!!!!!!!!http://forums.radiocontrolzone.com/s...=212320&page=1

that post proves nothing.

an lvc is a low voltage cutoff and prevents lipo cells from over discharging

REVISED LIST


-BK 12020---$280

-BK wanderer 10xl---$100

-Two Maxamps 3s2p (4000mah lipo cells from maxamps) lipo packs------- $500

-Maxamps 2s2p 7.4v 3000mah reciever pack made with 1500mah lipo cells from maxamps (no ubec b/c i'm running 1 airtronics 358 (200oz) servo and two 357 (.07 sec) servos, two fans, and the esc)---------$60

-2 maxamps Hyperion LBA6 Balancers $80

-Two maxamp "Low Voltage Detector for Lipoly 3S 11.1V Pack" $30
But the thing is, these are only detectors, they do not cutoff the load. In other words, these are LVD, when i should really be getting LVC.

-5mm gold everywhere (except reciever wiring)

Total: $1240

Maxxamps packs have sucky disgarge rates, Kokam and Apogee batteries are like 20c and maxxamps are only 12c.
