A few motor Question's
 

First up Hi, i've been looking at converting my MBX5-T and found my way over here from another forum,you where mentioned on a UK site as having a good sauce of info :intello:.

Now, i don't know a great deal B/L and lipo's, so bear with me :whistle:.

Now its not for racing,but if i like it that much and my local club let me race B/L,then i may convert my 6T :mdr:

I'm struggling to choose a motor and ESC combo.

I've been looking at these
Tekin combo

CC Monster combo Now i'm not sure on this as i read about MMM and this one is the MM :neutral:.

The other combo i am looking at is the standard motor and ESC that comes in the caster F8-T, i think its a hobby wing ESC ? and i'm not sure what the motor is,if anyone has some input on this,then that would be great :yipi:

ESC http://casterracingusa.com/product.p...8&cat=5&page=1
Motor

I'm not sure how good the caster stuff is,so not sure if its worth a look at.

I'm also looking at running 4 cell battery's and around 5000 amp,does that sound about right :mdr:.

Cheers Ross

sounds good, cant go wrong with castle or tekin combos. Hobbywing ESC is pretty good, but motor is crap. It can handle a truggy, but wont be even close to neu or tekin in therms of efficiency.

and if you decide for the hobbywing, take a look at hobbycity website.

Thanks.
I have read a little on the Tekin combo on here,there seams to be a problem with the rotors on the motor,does anyone know if these are ok now ?.

Also i've read on UK forums that some of the CC ESC can go up in flames,is that correct.

Cheers Ross

keep in mind people will post a topic probably when something has gone bad. i bet many people have bought the combo and have had no issues (i did). And these people wont open a topic here saying my motor works great. Don't bother, both are awesome.

Yeah very true. Just a quick one,if i'm to go for a lower Kv rating

will that give me more torque,if so will i lose a lot of top speed.

Ross

The Tekin rotors apparently did have problems at first, but all are fine now.

Any ESC can go up in flames if run incorrectly, or maybe just a bad component.

Ok,what about the Kv,if i lower it,does it affect top speed,i don't need fast top end,looking at what other people have geared truggys for racing, i would say around 40mph.

Ross

If you are getting the RX8 and Tekin motor combo, you can run sensored and use a lower kv motor than normal; just gear up a little. Shoot for ~28-30rpm. If using a non-sensored setup, I would shoot for ~35k rpm.

The RX8 is the combo that i like the look of most, so yeah it probably will be this one. Sorry, another noob question, why can i run a lower Kv if its sensored .

Ross

Because at low speeds, a sensorless setup has a harder time to determine rotor position. In a sensored system, there are actual sensors to do that so there is much less chance of cogging.

Are, I see. I will go for next lower Kv rating i think then,and gear for the 40ish MPH top end.

Cheers Ross

This one then

http://www.amainhobbies.com/product_...r-Combo-1700kV

:intello::intello:

Ross

Actually, this one would be better: http://www.rc-monster.com/proddetail...=tekinrx8combo

:wink:

:lol::lol:, is that because its 1350KV,or because its from RCM :whistle:


Ross

Because it is from RCM. And you can choose the kv from the list at the bottom of that page.

I was looking to get it from RCM,as i can use there mount as well :intello:.

Will the 1700 be ok for racing if i decided too ?

Ross

From what i have been running and reading, for your 4S setup, i'd be looking at the 2000kv truggy combo... i have had good success with it myself =) The 1700kv setup would be good if you race on a small tight track, and if you think may run 5S in the future...

I've also had no problems with the tekin motors btw (have had a 2650 buggy and a 2000 truggy, but not sure which design they are) - i have found them great =)

OK cool, this is the track i will mainly use,so it looks like the 2000 will be better :intello:

I would go with the 1700 or 2000 combo. Run it sensored it is the way to go. Only if the MMM was sensored i would be a happy guy. The reason he is suggesting it cause Mike at rcm has the updated rotor version. Which amain might not have. You wouldnt want to buy something and have the motor rotor blow up on you would ya.

:gasp::gasp:,i don't want no blowing up motors :lol::lol:

thats a sick track you got there. So many options overall.

:intello: 16 IN TOTAL :surprised:

i definatly recommend the monster mamba package.it is an easy install,just plug in and play.the rcm mounts and pinions are fantastic.

+1 so far from me!

Good to see you made your way here Ross! :yipi:

My 8T is almost sorted now and I'm dying to see it run. Had a go with a BL/Lipo Emaxx last weekend and that really whet my appetite to get this thing going!! I think there will be a lot of our lot with nitro's moving to BL/Lipo if it becomes easy to fit, reliable and the scares about using Lipo are put into context!:yes:

Hello Beanie,its your fault i'm looking into this dude :lol::lol:.

I think i'm going with the CC,what with you,Rusty and Kwik all running them it seams the right thing to do :intello:.

The only real issue i am having is a few people at HNMC not really liking the thought of a 1/8th leccy running with the nitros,but the chairman seams to like the idea :intello:.

Sorry mate!! :whistle:

I'm sure HNMC will get over it mate, although jealousy is bound to creep in :yipi:

Yeah i'm sure once i start running it with the nitro's all will be cool :intello:

the nitros will just be scared of getting there a*se handed to them by an electric:na: there is a couple of brushless setups at our club and they are visually quicker than the nitros. as cool as the smell and noise of a nitro is,the pure acceration on these monster mamba brushless setups is just plain wicked:diablo:
