Skelotonized the chassis, same powerful motor and One crazy Front end that alone has 13 total pieces. The wipers are easily changable and give a good surface contact with a spring shape.
One of the major developments on this model is the guide flag. This is what I consider a leap forward in the controlled chaos of gravity style racing. This allows for a gliding directional surface without too many spinouts. going pedal to the metal fast!, but still requiring a competent driver and concentration. thoughts?

This is one of 13 lead slead cars built by Doug Morris in 2012 based on a Car Model article in the 70s. It was built with a metal flag originally. Doug discovered that these were a full one second slower per lap than a plastic flag - he changed them all over despite all the work he had done to creat a custom metal flag.

Those look great. Thank you for sharing. Do you have any photos of the original metal flag? Here is my thought process.

I'm trying out some experimental models with some bigger motors to go extremely fast. The n30 being one of them.
The difference with the guide flag in this model, it is not a drop arm configuration which pushes the guide flag down biting into the track, but is instead pivoting with the front end to remain parallel to the chassis. So when approaching into the corners its gliding and guiding the car. While there is less friction with a pin, it is slamming into the curve and whipping the chassis around with the inertia.
My conclusion with this experimental model is the Guide flag is making contact with the curve transferring to a smooth steering motion allowing the front end wipers to maintain parallel constant contact for raw power and not jumping when going through the curves.
I haven't seen any wear issues on the groove and haven't had complaints so far.

Still in the experimental stage; these Batwings allow some weight to be transferred when in motion. Going to get a race video up soon.

Got some raw race videos up on youtube, first night out on the track, better tires and some more refinements, but they fly!

Nice track. Were all the cars on track gravity or did you let some Fray cars out there too?

First test run videos at a friends race night with my custom builds. We had 2 Fray cars and a handmade Green sidewinder racing along with the Big motor slot car and siblings. It was the drivers first time behind the wheel on these new builds. The bigger motor performs great at full load 20v!

The Lastest 3rd Generation design
Chasis #10
:possmooth:
Old car weight 25.8 grams
on 7 tooth pinon gear, 22 crown
New Chassis
New Car: 8 tooth pinon gear, on 22 crown smaller od crown gear.
New car weight 23.6 grams
New aluminum guide flag nut
The motor has also been also set back car from the old.
Outfitted Wizzard T Jet front wheels
The new design went out for a spin and is Wicked Fast!
smooth and drivable
only problem is is can burn off the silicone tires in about 5 minutes.
