BobbyD posted:George Mason posted:Running on Fastrack that, at the time, was clean. I had added an RPO car and a full length observation car to the five car passenger set. I did not check the tires on the A unit. This set was all MTH Premier with long passenger cars. The Dash 9 could pull the entire set by itself. I’ll check it out again. Thanks!
I'd have expected an MTH F unit to pull that easily. (though the full dome cars are pretty heavy correct?) A few of the repair guys here know better, I'm guessing the Dash 9 and the F3 powerwise are the same internally. What is the track radius? As the track diameter goes down, the drag goes up.
60 inch radius
