I run a bec , my steering servo would stop working when the motor was under load. Put a CC bec in it and it all went away, I was also able to step up the steering voltage! Aren't you done YET? :lmao:

Not sure why your servo would cut out with your motor under load but if a BEC fixed it...right on.

As far as bumping up your voltage...you can only put the voltage that you have available into your servo. If your battery is at 6v, the BEC wont amplify that into anything above the available 6v. If you bump the standard 6v up to 7.4, it'll only be at 7.4 as long as your battery has that 7.4v to give. But...Like I said...whatever works. I just couldn't wrap my head around the whole thing and was lookin for some input. Sorry for the slight thread jack tho. I guess I should've posted up a new thread for discussion.

Nice build. Those white chassis' just look sexy. Still think the white Wicked Cricket is the coolest lookin mini Ive run or even seen.

Im seeing a trend in runnin BECs on 2s. What are your thoughts on this? Since a BEC is basically used to regulate the 11.1v of 3s down to the acceptable ranges for your servo, and a 2s pack is already at that upper end for most of its cycle, Im wondering if Im misinformed or missing something others aren't.

The reason i run a bec is because the sidewinder micro cannot give my servo 6v continuous regardless of what th motor is doing. if you have a bec it doesnt matter what load the motor is under its still getting the voltage you assign to it.

I'm wondering the same thing J.D. I'm running 2S with a BEC set at 6V. I guess I'm being cautious since when fully charged my 2s is over 8V. Think I'll keep it in there though - doesnt take up much room.

Yea...thats the nice thing about the CC BEC...shes cheap and little...like my sister in law :shock:

I figured the same. Your 2s at its very peak is around 8v but its not there for long and by the time you figure in the draw of the mtr and esc...the servos not getting much above its 7.4 ceiling, if anything.

I was just curious because Ive seen a handful of mini builds lately where a BEC is being used. I guess safe IS better than sorry. "thumbsup"

Thanks,

Lmao nice post. the only internal bec i trust and have run before was the Holmes Hobbies Torquemaster BR-Xl. its just a little too big for my servo though lol

i agree 100% and yes im done for the most part... until i get more pp funds them some other goodies will be coming:twisted:. i need to get more steering this is just not enough man, but then again im coming it to my xr so thats probably not a good thing lol

its all good and no thread jack that im aware of HARDKNOCKZ. i have it at 6v because even when the battery is almost dead the cells still have 3.2v each so 6.4 together. so no matter what my pack is at in the mah its still 6v for the servo and 333oz getting to the tires"thumbsup"
the reason the tires would glitch is because the speed controller is pulling power from the servo to supply the motor when under heavy load. when you take the load off the speed controller(installing the bec) the speed controller no longer powers the servo so all its focus is on the motor"thumbsup"

I have mine set at 6.0v , since that is all the servo will take. I run a 18 turn brood which draws a lot of power.I believe the stock CC MMP micro only put out 4.8v and that was a little to low for the servo. P.S. I understand the fact you can't amplify voltage with the bec.
 
Makes sense. Everybodys setup is different along with their experiences...thats why I asked. When I took the BEC off of the FXR in my last mini, I didn't notice a difference. It bcame a huge discussion in our club with MANY different opinions. It kinda peetered out after awhile tho.

Ive only run the MMPs in my 2.2 comp rig so no experiences like you've described.

Thanks guys,
J.D.
 
In all honesty i probably wouldnt see a big difference either. id say it depends on the terrain also. if your in a place where there are tons of gaps and holes(like i am) you need something that will always give your servo the power it needs. it your on rock that does not have many holes then you probably wouldnt need it.
 
Well your point about the wheels glitching makes sense. You only have so much power available for both the servo and the motor so it makes sense that under a heavy load, one would draw power from the other. Of course a BEC will only cure this if its wired directly to the servo and not thru the esc.

Ya got me staring at my extra BECs thinkin I need to wire one up in the mini.

Ive been chatting with Don today and we're gonna start the Wicked Cricket build again so I'll try it in that new build.

Thanks for the info. "thumbsup"

funny you should mention about only if its hooked up directly to the servo as i used mini deans to connect my bec and servo and the tires were glitching like crazy so i took out mini deans and ran it through the receiver and the glitch went away. i have all my other trucks bec wired directly to servo and no glitching but on this one it just glitched. idk it messes with my mind lol. looking forward to the build and just think, whats it gonna hurt to add it.
 
The truck performed amazingly at The Indoor Championships and i was able to pull off the win. It was pulling lines easily that put my 2.2 was having trouble with so i couldnt ask for more. i would have finished all three courses but i blew the tranny on gate 7 lol so yea. will post video week

Wow, now that's a comfortable lead when you don't finish a course and still win! Good job and congratulations! "thumbsup"
 
Looks like a lot of fun, wish I could've been there. :cry:
$ucks blowing your tranny so close to the end, but better than having it happen at the beginning! Way to do work! "thumbsup"
