Well we decided to gut the thing for parts, like springs and such that we could use on our original super hornet my brother had from the 80's ,the springs were shot so we replaced them with the ones from the truck, man that made the handling a lot better :O we were going to try and use the motor from the truck but weren't sure which one was better? the hornets motor is a tad shorter and the gear is bigger but the trucks motor is longer by a 1/4 inch and the gear is smaller so more torque right? but the gear wont reach the fly wheel where its located.....bla bla bla how do i remove the gear from the top of the motor so as to add it to the truck motor? we see no holes for keys or anything.
