Recently I won a Fly Marcos in a raffle, those have a front motor and slightly wobbly stub axles, so they are not the best runners. I needed an excuse to try a printed chassis and this was it. I ordered the Olifer chassis that is made for the Fly Marcos and it was delivered on the promised date. The chassis was just about perfect as received. The only changes that I made were to shave the bottom of the guide flag holder and to sand the sides of the chassis a little. The car turned out to be much lighter than our rules permit, I did add some weight to the motor pod for a start, but the car was still a bit light when I tested it last night. The car looks to be a good runner, but it wants to tip at the limit, enough lead low in the chassis to bring the car to the minimum weight limit should fix that.
