well i kind of want to be able to run the rusty and the revo... so i want to keep the 5700 on it... when will the mmm come out? how fast will that alow me to go on 6s a123?

I can't say. I've heard the MMM should be out sometime in April, but I dont even know if thats remotely accurate.

As for speed, I would assume 45mph would be easily accomplished...especially with 6S A123.

eh.. would prefer to not wait that long... hmm... i guess if i wait i could accumulate a bunch of money. in the next 3 weeks i will get about 400 to spend so idk what i will do.

for 300 bucks what motor/esc can i chooe from with the 6s?


thanks alot bp

Ok, my choice would be the Quark 80B and a Feigao 8XL or 9XL motor, or you could spring for a Lehner XXL. They should only run about $175 for the XXL. If you don't want to spend that much, go for a MM and a Lehner XXL or Feigao XL. The MM has been proven on 6S A123 and 5S LiPo.

alright so what kind of speeds will i see out of this setup?

80b/mm 7xl
80b/mm 8xl
80b/mm xxl lehner

escs wont make a diff in speed will it? if so lmk the diff!

Well, techincally yes, but the difference probably won't be noticed.

An ESC with less resistance will allow more power to get through to the motor resulting in more power.

7XL on 6S will be a little hot, but none the less probably be into the 50's.

8XL, 50's too I think.

XXL Lehner, depending on KV and gearing, anywhere from high 40's to mid 50's or more.

A side note on Lehner motors. One big thing about a Lehner motor is the quality, which makes it extremely efficient. This means that it can produce more power given the same power output (less power loss to heat and other factors).

Don't take what I say as the bible though, since compared to most guys here I'm a brushless noobie, though I know enough to get me by. All those speed estimates are just what I read as typical results from other users with those setups.

well i am fine with those speeds. anywhere in the 40s is cool.

now to esc... between the 80b and the mm which one would be more suitable? will i need a bec with either one? (probably will need one for the mm but not sure...)

so pretty much for the extra money the xxl is def worth it? i dont wanna be spending an extra 150 or w/e for nothing uk?

would like the motor i get to be efficient... little cogging... long runtimes... and for it to stay farely cool.

Yes, you will probably need an external BEC. You will probably want the Quark...as it is built for 6S. 6S seems a little extreme for a MM...I would be ok with 4S lipo or maybe 5S A123, but anything above that is a little much in my opinion.

The Lehner is probably worth it. The Lehner is about 100 more than the other average motor.

I, personally, would go with the Quark if you can afford the extra cost. You will need a UBEC for either the MM or Quark as well. The XXL motors should only be about $175 as apposed to ~$90. I think it would be worth the extra to be honest. I had a XL3100 and on only 12 cells it would easily do 50mph with really old 2400 NiCads. I think a XXL would be my choice, and probably will be for my next motor. Mine ran pretty hot, only because of the very high RPM's, which shouldn't be a concern for you.

alright sounds good..

so would that cnc heat sink work with the quark 80?

so it would be 80b with the lehner xxl and 6s 123.

sound like a pretty good setup?

Sorry to jump in late here. If you're still considering going to a 4wd stadium - why not the Lightning Stadium 10? My brushless conversion of my LS 10 is on ebay right now. I think it rips on pretty much any other 1/10 scale truck out there.

Only reason I'm selling it is to do a brushless CRT. Just bought the rolling chassis this week so I need the cash. Just thought you might like to know about it. If you have any questions about the LS 10 - PM me.

decided not to go with a small truck. im lookin forward to this revo conversion!!
