No I haven't. They are too expensive for me!lol I can only get one ratio in Canada(cost about $57CAD) and seems to work great for the trailers but it would be way too slow for the trucks. Those motors are 12v too which would make matters even worse since the truck is 7.2v. I tried ordering motors direct from Servo City last year so that I could get different ratios but shipping on the $40US motor was $40US! I believe Mario had ordered from them right around the same time and got dinged an additional fee for duty as well as the over inflated shipping cost(wasn't happy). I am sure they would work fine as they seem to be very strong but these things I'm using seem OK for the cost. If I can get 1 1/2 years out of a $10CAD setup I'm happy.lol I have a hoard of 12-18v drills here now and they are begging to go into another 1/10 scale project. It's almost time to start building in the "manly" scale again instead of these dinky toys.lol
