this drill good?

[Rahulvyas]

Ok, what is the cheapest power source for this?
and what is the easiest and cheapest ESC for this motor?

[maddox10]

Easiest and cheapest. http://www.hobbyking.com/hobbyking/s...d_Car_ESC.html
7.5V max unfortunatly
The cheapest powersource, third hand 2.54Ah SLA.
Best bang for the buck, with the esc's in mind.

oh that looks great mad, but for 18v , 2S must be very underpower!

Then you search for a cheaper, lower voltage dril, a 9.6V one for example.

Those speedo's are in the end 45A, and @ 7.4V that's 333W peak, each side.
No drill , except de high end machines like DeWalts, will draw that in a normal drive of a robot.

Defector run on 3S in combination with 12V Gimsons.
And those are normal batterydrill setups with fancy mounting plates. With a different -lower voltage- 540 size motor those will do the job equaly good. If you draw 100W in a batterydrill based drive, , it's heavy pushing with great grip on the wheels.

well, its late they have already bought the drill...
maybe now i have to build my own motor controller!?

[maddox10]

That ain't cheaper, nor easier.

For cheapness , you can try to use the trigger in combination with a servo. Some of the old school feathers used that setup with a little bit of succes. But it ain't easy to get the reverse right.

Other option, the BotBitz TZ85's. Best bang for the bucks on the voltages you want to use. But I fear that's less cheap than you would wish for.

[Rahulvyas]

cant we hack a brushless esc (6s) to a brushed one with reverse?

[maddox10]

The Botbitz TZ85 is such an hacked one.
In origin it's a Tz85a from Hobbyking. if you can hack it yourself it's a tad cheaper than buying BotBitz.
On the other hand, I buy BotBitz when we need new TZ85's or simular.

[Rahulvyas]

maybe i will go with the trigger hack thing, later will get this boybitz ESC

Hey Plargen, I received one of the 3 drills i ordered. I opened up the body and took off the motor, not the problem is there is a sliding mechanism which switches the 2 modes on the drill, how do i lock it?? Also how do i lock the rotating motor to gearbox mechanism? it keeps opening on itself if i rotate is little bit.
Also, some gears came out , you know how i put them in place back?
