Anybody know the specs and any valuable info or characteristics of the Falcon motors 1 thru 7?

The stack, arm dia., wire size, wind, timing, magnets, brushes, bearings, can breathing hole sizes etc.

Also, correct me if I'm wrong. The first series was marked simply "JK" correct?

Then JKII, JKIII, JKIV, JKV, JKVI & JKVII? or was there a #six?

Thanks!

I don't have the series specs, but yes, the first series was simply marked "JK", I still have one of these. There was no Falcon 6.

Falcon 2, because of some mixup, ran "backwards" to the other Falcons. Other than that there is little difference performance wise between a 1 through 5.

[W. J. Dougherty]

From what I have on the 5 and 7 it goes something like this:

5: 75t/31w, .375 stack, .513d, 5' timing

7: 65t/30w, .375 stack, .513d, 7' timing


I don't have anything on the earlier motors...

F-1 and F-II should be identical to the standard TSRF series motor, and the TSR D-3 (3 degree reverse timing)is similar but different/reverse timing to the F-VII.

I believe:

Falcon 1
Falcon 2 was an attempt to add timing to the motor but it was put in reverse for what modern commercial raceway 1/24 anglewinders need
Falcon 3 advanced the timing in the correct direction
Falcon 4 was a different spec and were inconsistant in performance
Falcon 5 Back to the orginal Falcon 3 spec
Falcon 6 Different spec in extremely limited prototype quantaties around Chicago and maybe Hershman for testing? Maybe close to current 7 specs without Neo mags?
Falcon 7 From the IRRA website:

• 65 turns of 30 AWG wire
• Stack length - .375"
• Arm timing - 15 degrees nominal
• Diameter - .513"
• Magnets - Neodymium


Not sure if it was the Falcon 1 or 2 that were the same as the TSRF motor? I suspect it was the 1 since the some of the 2 were as fast or faster than 3's if used in JK Melenium chassis built upside down for the motor to run in the correct rotation.

[Hworth08]

Rob has things pretty close to right. We were racing the JK spring steel F-1 cars using the Falcon 1 through 4. That frame could be "flipped" too and was usually a bit faster with a 2 and right-hand drive.

[TSR]

• Magnets - Neodymium

The manufacturer of both the motor and the magnets claim otherwise.

Not sure if it was the Falcon 1 or 2 that were the same as the TSRF motor?

The Falcon 1 were recalled as they were issued with brush holders made of a material improperly heat treated. The TSRF motors were identical to Falcon 2 except for the commutator material.

The Falcons labeled "JK" were the ones with bad brush arms. Most were recalled, but some were sold to the public. The Falcons marked "JKI" replaced these. These were widely sold & they ran okay. I think your first batch of TSRF motors were some of these same motors because the Falcon 2 wasn't available until later. Call Todd Radke to confirm.

[TSR]

Actually, the order is not correct because the first Falcons were indeed recalled and what Jerry called Falcon 1 were indeed... Falcon 2's and so on!
Yes, the TSRF T3215 for home racing are like what Jerry calls "Falcon 1".

By the way, the new batch of Falcon 7 motors will be the same inside but will bar different markings, so no panic, they will be the same motor.

[Bill from NH]

So those Falcons marked JKI, called Falcon 1's were the second batch of motors. The 3rd batch, marked JKII, were the ones timed in the wrong direction. Those would have been ideal for the TSRF chassis, if needed.
