Neu 1515/1Y ampdraw?

[Ub Hauled]

Thanks for the feedback. What do you mean about 4s2p?(have to ask to be sure...) typical 2 x Lipo 4s 3000mah+ on each motor? And when it comes to esc`s, what will you recommend? Will there be any news from CC before the summer, thinkin about ICE?

4s2p means:
two 4s packs in parallel, that way you'd get double amperage for longer run times and smoother power through the ESCs.
I don't know about any new releases coming down the pipes from CC, maybe someone else that's better informed then me could give us the "skinny" on the spring releases. It would be nice if the Water version of ICE came out.
I hear good things about the AS speedos, if they are easier to get and support where you live then it may be a better option since the CC 240 is American.
Also, from all the CC ESCs I've used, the Hydra 240 is the most reliable one, I've had my share of burned ESCs but the 240, it's all around decent.
The MGM ESCs are good as well, I have seen them take great abuse but like any other ESC I have seen them fail w/o a reason (not willing to start up)... just like that.

two 1515/1y's only a 33" hull seems like extreme overkill! A single 1515/1Y should push it into the 50mph+ range! BUT, you're going to need a 200+A ESC to be on the safe side.

What may be overkill to you may not be to him, eye of the beholder...

Are the AS the controllers from modellbau-regler.de?

If they are... You will love them I'm running 1521 1Y with them on propshop 4517/3's amps should be acceptable

Sounds good. Its the one`s from modellbau-regler.de. I heard some rumors that they are coming with a new 200A esc very soon. My brother is probably buying them for his 1521, so maybe I just order together with him. Do you know how many amps your setup is pulling?

Thanks for the information. I still have some more time before the ice is gone here, so I will look a litle further. But the AS looks interesting. And if CC comes with something new that could be of interrest.

Not yet, dont have an eagletree expander yet

[vvviivvv]

yes there is a 200 amp version comming out it's 10 euro more i think


it is a 200 amp version was origionally going to be 170 but after tests 200 http://www.rc-raceboats-world.de/xos...gler-c-2_12_30

thinking about it i got annother 150 this week, and micha told me there so busy they have a order for about 68 of them at the moment

[vvviivvv]

i stand corrected,

Hi Liam
You can order now but the controllers are ready at the end of february 2010.
Perhaps in the middle of February but not earlyer.
The Price for the AS26/150BL is 279 Eur and the Price for the new AS26/200BL is 299 Eur.
The shipping is 17 Eur.

(well somehow i managed to get one on the 5th of January )

So if he went with twins would the 120s still be a bad idea?

[vvviivvv]

Not in my opinion as a hpr 115 cm on twin 8xl's can run 66mph on hydra 120's

[bjornar]

Hmm, ok. So maybe the Hydra 120 will be big enough for this setup? I dont want them to poof. I guess everything depends on the choice of props.

[Unsullied_Spy]

Brushless motors pull amps to make power, the more load you place on them the more amps they draw to build that wattage (volts*amps= watts, hence why high voltage low KV setups pull fewer amps and run more efficiently). How many amps you draw depends entirely on how much load you place on them, but I've seen 1515 1y motors pulling over 200 amps (very briefly) on acceleration in 1/8th scale trucks.

[mickvk]

I agree with previous posts that the 120 is probably light unless you're careful with prop selection. Here is some information that you might want to review... The eagle tree graph is real life data - 6S, 5000MAH, 32" Deltaforce vee, 1515 1Y, Hydra 120 LV, Octura y536 36mm prop. The other two forms shown are theoretical information from FECalc. It went like a raped ape but amp draw was over limit so this is an example of a bad setup :)

[bjornar]

So 2xAS 200A will probably be a good investment? I dont want any plown escs...
