Help me choose motor??
 
Hey guys I am looking for some help and am not sure what motor to get. I just bought 2 of these Kokam 4800mAh 3S1P LiPo Battery packs. I plan on putting both of these in my Gorrila Maxx Revo 3.3 along with my Quark 125 controller. I am not real sure what motor can handle this. Any help or suggestions would be greatly appreciated. Thanks in advance!! #12

How much do you want to spend? On 6S lipo I would run a 9xl or 10xl.

If you want to spend more a lehner 1950/8T or neu 1515 2.5D would be a good motor choice.

you would definatly need an rcm heat sink for the quark....doesnt the quark have thermal problems on 5s? or was it 6s?

Quark is fine on 5s, on 6s it is going to act funny, i forgot to mention that, #12. Id reccomend 5s for the quark 125B.

Stop with all the slang already!

#12 - If you havent already ordered the lipos, use 5s, or a different controller!

You didnt have to post all that info ; couldve just read it off tower.

That is a good esc, but it cant be used without a mechanical brake (in nitro conversions this esc would be acceptable). Otherwise it is of no use in our electric r/c's.

the one you mentioned has trouble with neutral with anything other than a plane transmitter. the best for the job is the MGM 16024 http://www.rc-monster.com/proddetail...MM160243sHCS01
BK 9920 can handle 6s as wellhttp://www.rc-monster.com/proddetail...od=9920warrior

Sylvester 01.16.2007 10:08 PM

Its more expensive, but atleast it has brakes! :)
