First post, first year cub scout, first car.
Done a lot of reading here but apparently not enough.
Wedge design, must use factory wheel spacing.
Drilled holes with the the guide block, 3 wheel car, 1.5 front and 2.5 rear axle bend.
Thought we were done till I read here that when rolling the car backwards that the wheels are to stay at the axle head.
On my sons car, both wheels move rapidly to the car body when rolled backwards and out to the heads when rolled forward.
Does this mean that both of the axle holes need to be tilted toward the front of the car?
I have rotated the axles both directions but that does not change the wheels moving to the body.
We removed the front wheels, put scotch tape on the bottom of the car and let it roll down a 7' ramp and it rolls perfectly straight down the ramp and onto the floor and doesn't change direction.
Running out of time we have 4 days left if we are going to try to correct the rear of the car.
We did build a first car but found out 2 weeks ago that the wheel base can not be changed, we went with a aggressively long wheel based car. We thought we did a good job on this car and was confident. After reading here and adjusting the new car, on a smooth 7' long surface elevated 1.5', the new car beats the old by 2 car lengths even with the possible negative toe on the rears.
With the jig for the axle holes, I thought this eliminated the out of toe problems?
Any help would be appreciated, we have the car sitting on the table looking at it not sure what to do next.
