update December 2023: I guess I never finished this post but I figure it has enough work in it to go ahead and publish as is.
Datasheet:
Dimensions: 38x22x23 LU long/wide/tall. (12x7x7.2 inches)
Power: Power Functions rechargeable battery.
Propulsion: 2x RC motor.
Steering: None.
Completed: Mid-June.
I had wanted for a long time, to create a model that could move under its own power, using only air.
I made a few attempts a while back using a PF XL motor, and then two, geared up a high ratio. These all failed, even without the weight of the batteries, Which I would hold behind the them as they attempted to move forward.
Now, having two RC motors, which work far better for high speed applications. and a PF lithium-ion battery, I was able to construct a very successful air driven vehicle.
Another important factor is the propeller. In my past attempts, I used dedicated propeller pieces, which were sturdy, but weak in their propulsion. But I couldn't seem to build a custom propeller sturdy enough.
The design of this model actually started with the propeller. I created a simple hub that provides placement for two propellers, at a ninety-degree angle to each other, and forty-five degrees from the axis.
The design was simple and strong, and from there I connected the motors and some wheels. It was a rather crude design, but it was very light, and could pick up a lot of speed given enough space.
The initial design used some standard road tires, which were smooth and fit the scale alright, but I soon switched to more of a balloon style tire.
