BEC in Micro-T?
 

Hey, I have a Micro-T in a box sitting in my room that I was going to sell (its still stealed and brand new). I was going to run it with some buddies, but they never bought one, so I never opened it.

I want to run something with more power than the stock battery, but dont want to drop the cash on brushless. However, I dont want to risk the speed control by running 2S lipo. I was thinking of running the 2S through a BEC first, so the ESC receives only 6v. This should help alot, since the ESC will receive an absolute max of 6v and not stuff like 8.4 on a freshly charged pack.

The stock battery is 150mah, and I heard it runs for like 10 minutes, so amp draw can't be more than an amp or so at most. I figure a 3A BEC should be plenty for it.

Any thoughts?

That should work fine. I would go with the one www.dimensionengineering.com has. It has a built in LVC as well. I to was thinking the exact same thing...

Thats a great site squee - has a bunch of cool products.

Too bad they don't make the "SmartBEC" in 6V. They only make it in 5V. That should still provide a pretty noticable increase over stock, just not as much as I had hoped. I will keep shopping around though.

I also found another problem. Doesn't the Micro T use an integrated receiver/ESC? This would prevent the ability of using a the Cutoff.

no bp theres no need, the stock can do it just fine, ur just adding on un needed wieght

Unfortunately, it does...If you open up the Micro-T, could you measure the battery compartment for me please? I just placed an order for a 460mah LiPo cell, and a few small things to build the pack. It should fit, or if not, I think I can make it fit. Its only about 8mm longer...

Are you sure the stocker can take double the voltage it is intended for?

yup, its actually rated for 7.2 volts

go ask anyone at one18th, they all run the stock sreedo no probs... some upgrade to a novak speedo, but most run the stock stuff, the motor and speedo does fine, and i have tired it to with a lipo from my buddys micro t,i used a max amps 2 cell 150 mah i think and it had room to spare

heres a pic to prove it stright from losi, look at the sticker, it says 4.8 volts to 7.2

In the manual it says otherwise... It says max is 4.8 and use of Lipo voids it etc etc....

bull, it works fine man, as long as the pack isnt insane mah.. squee is probably pushing it, id do 220mah MAX after that is when probs happen because it runs for waay over 30 mins

Exceeding the mah rating won't cause any problems other than fitment. Actually, it's better for the battery to discharge less than it's rated for...

yeh it will because they run soo long and heat up the motor, and speedo... the motors rated for 4.8 volts so ur wearing it that mush faster with lipos, and speedo heats up

Thats why I'm only gonna run 1 LiPo cell for now...

why????? do u want a vid??? or what??? lol it works fine

That's a weak reason! Sounds like some effort needs to be made in cooling if that's true. :)

its the reason tho.... and lil a fan the size of what? a motor shaft??? :D

A video would be nice, but either way...I'm not worried about it since I'm not 100% if the battery will fit. So why spend another $8 on an extra cell to make a 2S if it won't fit?

true, and mah id be good, i c what ur doing lol i tohught u were going to do a 480 mah 2 cell.. nvr mind

and i need to find it first lol

I had planned on it, but then I desided not to...

yeh, do u think 1 cell is enuff?

here yah guys go! a whole thread on it, and thers a vid in there also

im lookin for the other vid


EDIT:

heres another one =)

Yea. 1 cell should be enough its its 4.2 fully charged. Whats the stock pack voltage fully charged?

around 5 volts cummin off my charger at .5 amps

Squee - the stock pack is ~10.6mm thick, each lipo cell is 3mm thick, so it should fit fine.

I'm still deciding on what to do...but chances are I will go ahead and run 2S if I decide to keep the truck.

I am wondering if I could somehow stuff a Mamba 8000 in there and get in the 100mph club lol.

yeh rite LOL

that would be like a mm in a 18 t or mini lol

all tho someone at one18th has a mm5700kv motor and mm speedo in his rc18t lol, he runs with 3 cell lipos, and now 2 cell limns

Yea...I was about to say there is a guy with a MM in a 18T...

I have a strong desire to run something crazy in my G2R. Something like Dual 1950's lol. Of course, logic and wallet don't agree.

no logic aggrees 100000% :D

its the wallet being to skinny, ur wallt is the only thing in life u want fat lol, g/f stays skinny =P jk

I don't think the pavement on my housing track would hold up to dual 1950's LOL

lol ur diffs wouldnt like it much either :D

heres ur proof again from losi!!!! losi has a lipo kit for it now :D!!!!!! 2 cell lipo!

I stand corrected.

Yea... my diff's would just commit suicide up before I even set the mesh.

hehe, i know what im doing lol

Crap thats expensive for that little lipo. You should be able to find little lipo pack like that for $20.

Oh... I forgot, the Losi logo makes it worth more.:rolleyes:

its the charger bro, the mini t batt chager is 40 bucks.......

http://cgi.ebay.com/GWS-Lithium-Poly...QQcmdZViewItem

$8.... $12 with shipping.

yeh and the 20 doller batt, thast from them, horizon will probably be 40 or 50, and thats will a fool proof charger thet u cant blow ut lipos with becasue its for he batt that it comes with
