Are you based in the US?

I would stay away from hammer drill mechanisms as they are a pain.

Difficult to say on the others as I am not familiar with them.

Dang, the postage on that one is higher than the drill itself (USA to Netherlands)

[Rahulvyas]

well, my uncle is visiting me, he is from usa.

so hammer drills are difficult to open?

i tend to find that the black and decker drills generally use plastic gears but if your not over volting them then it should be ok

Easiest way to see if something is good/reliable is to search for it on a place like amazon and see what the reviews say. Read the lower reviews too as they may highlight things like reliability issues or poor manufacture.

In this case it seems fine with only one mention of a poor build and 2 people saying the batteries didn't last. Given you wont be using the batteries you can ignore this.

Do this sort of thing before asking on here. Its quick, its easy and it means you will learn more than us just giving you the answer.

[typhoon_driver]

No it's not that they are difficult to open. It's that the hammer mechanism makes the gearbox more complex and you will have to disable the mechanism to get the drill to work as a drive motor.

[Rahulvyas]

@typhoon alright, i read that hammers are powerful compared to normal drills, are they?
and higher voltage means more torque?

@Eventorizon- i will do a research then, thanks for the tip


@plargen- which ones is the cheapest drill which is good for this use? and that most featherweights use?

[Rahulvyas]

http://www.ebay.com/itm/RYOBI-ONE-PL...item258a64ec9e

getting these ones (3 pcs)

[plargen]

i have found ryobi drill to be robust in my robots ive never had to change a motor or gearbox in any event that they have been in and they have been smacked around quite a bit at GSL the last 2 years, although i did have to tighten the 2 screws holding the motor in after the second year lol ...... the version i used were CHD-1201 over volted to 4s

if you after 18 volt i would suggest these

or these depends how many you need
http://www.ebay.co.uk/sch/m.html?_od...1801m&_sacat=0

they look the same as mine so they should have the proper bearing on the drive shaft which makes them nice and robust

[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.

[Rahulvyas]

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

[maddox10]

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.

[Rahulvyas]

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