As long as your motor does not draw too much amperage no it should not.

However trying to drag the weight of a sub-c battery pack (your 3000) may cause your motor to draw enough amperage to fry it.

In any case it is not advisable. 2/3A cells are available for under $2 so if you make your own you can save a bundle.

Another idea is to use the 6-cell packs they sell for electric airplains like the Aerobird. They are so simple to split into saddle packs and use in Micros with pan chassis. They are made of 2/3A cells and sell for around $20. That's what I use and they work great.

I think that 4cells would be the best for a speed 300 or the flash esc. if you go with a m3 cubic you could use 5-6cells but you can't run it for long lengths of times. but if you go with a speed 380-400 you could and you would be beating 1/12th scale pan cars. but if you really want speed go with a brushless set up. but I think 6cells would fry the motor not the esc but I wouldn't try it. I would go with 4 cells.

Does anybody know if the HPI Micro servo-saver set will fit 'micro' servos? I have a tiny FMA Direct S80 servo and I need a servo-saver for it. I don't know the spline count but the output shaft is between 5/32" and 11/64".

you propably will need to get a servo saver made for micro servos

hey all,
just a couple of questions,
i have a micro with megatech front knuckles, hpi steel uni's, a custom 6 cell pack and a chubby big block kit.

and i was just wondering what steel pinions fit on the big blocks? cause i hve a steel HPI one that wont fit on the big block, so i have been using the stock plastic ones and have wrecked one already. so what metal ones fit?

and i just snapped my chassis in two, so i would like to know what the best one is? i am looking at the exo's and the penguin pan chassis.

any help is appreciated,

thanks,

for the pinion to fit the big block u will need to sand down the aplines on the motor shaft, it is easy to do.

for the chassis the two u mentioned are great chassis, I have the penguin pan and i love it to death.

[microrcdude]

I would just drill the hole in the pinion bigger. That is what everyone around here does.

[Animeboy123]

really its a whole lot easier to just sand the aplines down then drill a bigger whole into a steel pinion.

All i did was set up electronics and set the motor on a stand and throttle the motor then put a peice of sand paper up to the shaft and sand little by little off and thats it.

[yeeehaw]

that is what I did and it works And it is by far the best way to make a pinion fit, also if you experimented with different teeth you will have the right size splines instead of drilling your pinions every time you buy one.

The splines are pretty soft so it's easy to do...I actually used an xacto knife to trim off the splines first then sanded the shaft...i found this to be easier and quicker then sanding alone.
