setup differences - RC-Monster Forums

i run an lmt 1950/8 non high amp with a quark 125b on 5s or 6s lipo. i have a problem though. the quark doesn't work properly on 6s. from what everyone claims 4s is great with the quark, so i would like to run a 1950/6 on 4s and 5s with the quark. what would be the performance differences if any? thanks, tally!

Runtime would suffer a good bit...

Squee is right, your runtime will suffer running lower voltage.
Someone mentioned to try running the quark on 6s without the bec enabled. Antone try this yet?

Probably everybody. The BEC is only rated for 10 cells.

Hmm, I thought there was a mod you could do.
I ran my Quark with a BEC without making any changes.
I see in the instuction manual that the OPTO Modification says to disconnect or remove the the middle red wire from the pin of the receiver socket.
This may be a dumb questions but ,what does removing the red wire do?

Disable the BEC.:)

OK,
So I never disconnected the red wire and ran my system with 5S and the Unltimate BEC. I did not observe any problems there.
I never tried 6s because of the stuttering/cogging problem I heard everyone talking about. Has anyone disconnected the red wire and still experienced the stuttering/cogging problem?

Yes. Everybody who has tried 6S to my knowledge...

I cant give you any answers simply because Ive never owned a Quark befor.
Castle Creations also advise the user to take out the red wire when using a receiver pack or a seperate bec.

When the truck coggs with 6s and a Quark controller, does it make a crazy stutterring like the one I've discribed in my thread?

squeeforever · 10.16.2006, 08:28 PM

I don't think so. I think it coggs kinda bad until it gets moving...

tallyram · 08:41 PM

as long as you give it throttle, it jerks really bad. cogging is putting it lightly!

back to the question. i would really like to use the controller that i "wasted" money on, but what would be suitable replacement for the quark. i would like programming options and an lvc. i also have 12020 that has a problem losing midrange throttle. please advise!

squeeforever · 10.16.2006, 09:16 PM

I would choose the 24160...

tallyram · 10.16.2006, 10:11 PM

it seems like every esc has some kind of compromise. whats the compromise with the mgm's? that is what has driven me to nitro.

starscream · 10:17 PM

Price and they don't work with FMA DPM's
Hang in there, you'll have a whole new line up of issues to deal with if you go nitro.
