I am not going to the mat on this topic, so get off of that. It was just my opinion. And if you feel a due date is correct for chassis kits or parts, so be it...

[Phil Irvin]

With the way everything 'speeds' down the electronic highway. 90 days, 3 months, lead time on new products and good availibility sounds good to me. Having a once a year due date, I think, slows down and kinda hurts both racers and manufactures when they have something coming out that is better but don't want to produce another run of the old stuff to keep the racers 'happy' when they want to build a new car or paint a new body.

But then again, if a manufacturer decides to make a 10,000 piece run thinking for a year, he could get stuck with 9,000 old pieces... A catch 22...

If it's approved, it's approved. The only thing that has to catch up is the manufacturing process and filling the distribution chain. No need to wait in my view.

On the re-buildable Pro Slot 4002 motors, is it permissible to paint the cans before sending them off for the certified sealing of said motors?

Black wrinkle is very Retro again.

Thanks.

I would like to ask a question of the dimension of in-line motor brackets for Can-Am & F-1.

The regulation says:

Chassis Construction:

3a. Each car must have a one-piece brass rear
bracket consisting of at least three sides (vertical
or horizontal), with each connected side having
a minimum width or height of at least .200".

Is the motor bracket used for this chassis legal in terms of the above article?

More specifically, the lowest point of the motor hole should be higher than .200 inch from the ground?

Thanks in advance,

Haruki

[Noose]

That looks good to me.

[MSwiss]

The part under the bearing (that can't be .200" in a hypoid situation) doesn't count in that dimension.

[Noose]

The rule is to provide guidance on the width of the "arms or "legs" extending rearward on the sides from the the motor plate. The arms must be no less than .200" at their narrowest point.

[usadar]

Thanks a lot for your explanation.

It is very clear to me now.

I have a question for you guys. Since the question and answer thread is locked I guess this is the place for answers.

I have noticed that Falcon 7 motors now have a PN of JK30307. Is that just a new PN or is there two different Falcon 7 motors; JK30207 and JK30307?

[MSwiss]

JK #30307 is a Hawk 7 and not IRRA™ legal.

While being FK style, it's a totally different motor visually with a hotter wind than a Falcon 7.

It is legal for the JK Spec Retro class, which is not an official IRRA™ class.

JK no longer sells the Falcon 7.

[Fast Freddie]

Thanks for the response, Mike. Is the former JK F7 the one that is now sold under the TSR brand? Does it still have the same specs as the old JK F7?

[Ron Hershman]

Yes, it is, and yes.

[Fast Freddie]

Thanks, Ron.

[JohnnySlotcar]

How about measuring the body thickness as posted in the rules? It is starting to look like ISRA racing with the paper-thin bodies? Come on guys, this is fun racing.

[Noose]

I measure it. I guess you have been OK and have not been introduced to the Spirit Gauge. LOL.

[Larry Mattingly]

And, the 'spirit gauge' has sent a few to the back of the tech line... LOL.

[Noose]

Yes, it has. LOL.

Hi, IRRA™ BoD,

I would like to know if the grinding off some brass from K&S brass bars by an old sculpture machine is legal in chassis construction.

Examples are shown at the center bars of the F1 Chassis shown below:



Thanks in advance,

Haruki

[Noose]

Looks OK to me.

[S.O. Watt]

Hmmmm, must have a "machine shop".

[Ron Hershman]

Or a Dremel and Dremel "drill press".

[Noose]

Correct.

[Phil Smith]

I thought machined parts weren't allowed unless mass produced and available to everyone.

[John Streisguth]

Only if using water jet, laser, or EDM processes.
