OT:
@billy bob, yup weather here is pretty nice!, you must have stayed at either Bayview Park Hotel or at Hyatt!.. if you have a chance to visit sometime again here perhaps i could show you some of my trucks!
@kalkurap, i use worm gear on 1/87 scale only to save space on the tiny truck, low gear ratio is very easy to attain using worm gear but even an ant could outrun your truck!, but it is quite easy on your electronics.
brass gears of that size (for 1/87 trucks) are non-existing here unless i ordered on the net, which i preffer not to because just for the price it, this may force my wife to kill me! hehehe,
