Got bored with the 32 ford body and painted this last night.

Might have to run this instead of manta ray cause this looks really cool!

Can I assume you changed the motor mount too. Or does a 16D fit in the original 26D mount?

 

Sorry to ask so many questions, But if your mount is original? That's what I am looking for in my parts bin.

 

 The 26D hole is larger so it's just hanging via the screw. The front end is pressed down with some steel wire...16D has small gaps on its sides, no snug fit.

While not part of my "collection", I did build this for a friend in Australia.  I assume he still has it, but its based on Dynamic bits including those floppy front wheels.

 

 

 

 

 

Built in 2009.

Ok, I see it for the motor but, not for the idler. A very interesting solution to, to, what was the problem that drove them to this? The size of the motor? Speaking of which, are they really toothbrush motors?

Freestyled this today. wanted something that can handle a flat track better. didnt plan the tire clearance gonna have to sand those down a little more.

[Mad Mark]

About as low as it can get.

[Mad Mark]

Went testing and at first thought it handled pretty good and was nice and slidy. after inspection the chassis was dragging from the tires being too small. so I put on some slightly taller ones and now the car grips too much and just understeers and pops out really easy and is a little tilty. going to try those first black rim tires with a large hub not super grippy tires and see if I can get less traction. also dialed in ride height and it’s a 1/16 lower in the front. also wonder if track width is just too narrow in the rear with how I have the tires inside the wheel wells?

[Mad Mark]

Also tried guide lead changes and weight on tongue. didnt seem to make much difference.

Could be the rears are too wide. These chassis were originally designed for half inch wide tires. With the brass outriggers you have added, you might want to run 5/8ths wide rears.

 

I never liked the bend-in-the-middle chassis. With a hot motor it was too hard to get around a corner without lifting the front and popping out. I know all the hot shoes used them, but they were better drivers. They also used solid brass slab pans, which added weight down low. Properly set up, these chassis were unbeatable back in the day.

thanks for the tips. i tried locking the drop arm solid and didn’t notice much. the other tires I put on where 1/2” wide and it was still too much grip. was thinking some weight on the front corners of the brass rods behind front wheels? didn’t have any only a dynamic bolt on lead tongue weight at the time to experiment with.

[Mark Onofri]

If nothing else, it looks great! I especially like the shaker type mounting of the jail doors. Might have to copy that, it's a great idea!

[Mad Mark]

Think I got the car to handle better but I also burned up two blue wire 26D’s back to back unfortunately. the motors that burned up I haven’t turned many laps with so either they where about to go or the tires where slightly dragging on my pan. the cars they where previously on handled bad enough to only do two laps or so before pulling them. Seems like a ebd 16d fits in the chassis barely so I’ll run one of those Hong Kong motors from now on.

I wonder if the tires you were running grew once they reach speed, effectively like putting the brakes on? Bit of a bummer.

theirs like a 1/8 of sidewall doubt they would be able to grow much but if it was rubbing it wasn’t too much but maybe enough to kill them. i was able to stop before total meltdown so endbells are still good just the blue windings turned a almost green. pretty bummed burned up a cool purple dynamic mill with the sticker still on. oh well.

Angry Mark,
The Corvair Monza SS is one of my favorite. I didn't think they existed but,in the past month I've seen three (3) . I'm wondering if more than one manufacturer produced them. Mine has a flat where the cockpit is and, your's is recessed,as were the other two (2) that I've seen resently.

[Mad Mark]

Finally got this body mounting figured out. sorta a roundy round lookin car was thinking of making nerf bars and flathead zoomie exhaust.


Also good excuse to run my AJs whitewalls.

I was just texting with Jarius about making multi coloured tyres. Yours are really happening!!! They were what's now! You were a sQuare with out em.

Far out! those are a hot item. I still don’t have any.

Mark, they work well on a clean, dry track too. I put a 7/8" pair on my first scratchbuilt chassis in '68. They are still as soft today as they were when I put them on. For some reason, the Candies that show up today are 1 1/4" dia. I haven't seen any 7/8" ones show up. Both sizes use threaded plastic hubs. I'm thinking they were available in soft & firm silicones.

I have a couple of swirl pairs. Another thing I saw in the counter at the race track when I was a kid (the other being a Russkit Black Widow) that sticks with me today. I absolutely love them!

 

Martin you should sell me those swirls. Let someone else enjoy them for a while.

[Martin]

Phil, there could be something else I want more? PM me with a trade If that helps? I am not buying or selling at this time, just putting cars together and having fun.

[Phil Smith]

Martin, I've been racking my brain, but I can't imagine I have anything you don't already have multiples of. I'll keep trying to come up with something.
