:ö: thanks thorsten,
i was able to lower the gear ratio of my truck last night, i got more than enough torque to climb fingers!

, this things are so cool!!!!

, three thumbs up for you sir, YOU'RE THE MAN!!!
one more thing Thorsten, this is quite a long story but here goes; i'am using a GWS micro RX rated 4-6 volts and a Pico standard 5.4grams servo rated 4-6volts, and my ESC or automatic speed controller is a modified Pico PC-9 servo electronic board rated at 4-6volts, early this morning i charge my 4pcs 50MaH battery, that should be 4.6 volts right?, then i plug it to my truck (which i've already done before, when i test all the electronics before installing it on the truck) to my surprise there's a smoke coming out of the servo!!!

, i immediately remove d the battery and i thought it was a short circuit, so i open the servo to inspect for some loose wires, but there was none

, the only burned thing was a tiny black chip near where the positive wire of the servo is soldered, i attached the battery, again, and this chip emits some smoke and almost turned red hot

, have you encountered the same thing before?, what modification have you done on your servo to deal with this situation?. thanks man! -æ
