There was a thread somewhere that I posted in acknowledging that I had purchased a set of Joe's Mr. B fenders, and he'd responded with his thanks and a request for pics of the finished project. That thread has been deleted or moved to a forum I cannot view, so I will post anew here. This is Gavin's (age 9) "High Velocity." He built the entire thing with very little assistance from me (VERY proud of him), including the Photoshop car cover design, chassis cutout (using the soon-to-be-released Skywalker Body Jig System), drill (using The Clear Jig by micro ), Scout axle prep (using DD4H kit), wheel prep (using Evolution mold-matched wheels and Simple Green bore sealer), and of course the "Mr. B will wreck ya" fenders by Professor Moriarty He took 1st Place Webelos, 2nd Place Overall (behind only his little brother, also featured in photo below), and 3rd Place Best Design (as voted on by his fellow Scouts).

NICE! Good job. Did he sand the fenders on the bottom for the DFW? They look like some low hangers or is it just the picture?

My review of the fenders:
VERY easy to install - even for a kid.
They are a little wide. While we didn't sand them down for weight, we did sand down the inside edge about mid way on back to rear wheels, as well as the front leading fenders in an attempt to keep them from sticking out too far past the outside wheel edge.
A touch too tall in the middle for the the thickness of his chassis. The chassis almost fit in the side cavities of the fenders, so we hung them down a tad lower so there would be more glue surface in the middle. Most of the glue was applied at the ends, though.
Weight, of course. I've read here that they can be sanded down, but I felt that was a bit beyond his skill and he didn't want to mess up the finish on them since he wanted to leave them as they came. I think his chassis with fenders was about 8 grams heavier than his brothers chassis with balsa fenders. The difference in average times between the two was exactly a hundredth - all else was as equal as possible given two different builders (wheels, axles, prep products, chassis).
Wheel gaps were pretty nice, as you can see in the pics.
Overall, great product, especially at this price point. Makes X3 design accessible to any Scout.

Skywalker, I don't mind them sticking out that far. Look at the aero of funny cars and you'll see this is predominant design.

I've found wider fenders to be slower than thinner. Would love to see one of your simulations on the difference though.

I agree with Skywalker...why move more air than you need to?

That car looks great!
3rd place for the looks? Tough crowd out there.
Well... I am with Chuy on this one... but have decided to reduce the width none the less.
The new design will also be filled in more where it attaches to the car, so it should resolve that problem at the cost of a little more weight.
Thanks for posting these Scott! Great job!

The 1st and 2nd place design trophies went to hand-carved, hand-painted cars, as I think they should have. I think this car is cool, but in the end (aside from the hours of Photoshop work he put in), Gavin's car is basically a sticker and assembly job. Cool; I'm anxious to see what you come up with. I like that the DFW trailing fender was labeled and closed in, but I don't think any other inside wheel well need be. The NDFW leading and trailing could be designed to butt right up to the wheel with no gap, thus no air could get in. And neither the leading DFW nor rear of the trailing fenders needs to be closed in (can't remember if they were or not though). That should buy you a little extra weight for the mounting surfaces.

Thanks Scott,
Yeah... I figured that I would close in the rear ones just to be fastidious...
Especially since the extra weight back there would hardly make much difference.
I wonder if they help at all with the aero though... Chuy?
The front right fender I also closed off just in case some air would get trapped in there ...

Did you make these changes yet? Made the changes for 5”- 4.75”- and the standard wheelbase.
