And at $200 or more there's still no guarantee it will be a good one.

Totally agree

And if your miles ahead in a limited motor class/FK there's dam good chance your cheating

We ran our 6hr Enduro again over the weekend. This is our motor after 6hrs plus practice and run-in. Could have gone far longer. Calculated 8.7m revolutions for the 6hrs at an average of 24.7k rpm.

One of your local racers, Pete Varlan, is the one who did a scathing critique of this motor, on Slotblog.

I don't think he has any Retro agenda.

I just mention it's weak spots.

I sell a bunch of both this motor and the Retro Hawk.

The 4002FK strong point is it's brakes.

The Retro Hawk's strong points is that you don't have blueprint it first, like the 4002FK.

PS-If I didn't want this motor to succeed why did I develop a tool to fix it's main issue, the misaligned hoods?

And I have one and it works really, really well. Too bad I need one, but that's how it is and how it's always been.

I've been at this for decades (over 5 if you must know). I've melted, burned, broken, and exploded more motors than I can count. By the time the 16D evolved into the Deatnhstar, it was a comparatively decent item for its time. Not great but at least we knew that we were dealing with... a cheap, low-performance item. Adjusting things was a necessary evil and thankfully, it was easy to do without unsealing the motor. The Deathstar has departed and the 4002FK seems to be taking its place. New design, newer tech, hopefully better materials. Should be an improvement!

Alas, it is not, and that makes me sad. An entry level class is far, far, far better off with a Retro Hawk or similar motor that doesn't encourage diddling.

And the frankly idiotic argument that the 4002FK is economical makes me even sadder.

[swodem]

FK is more of a 'standard' class down here rather than entry level. I would guess 90% or more of races use this motor. There is some S16D, G12 and the occasional ES.
Given those stats, it's better to have an FK motor that may require the odd brush alignment (recent batches seem better) that motors that are as disposable and last not much longer than a set of tyres

A little bit of an exaggeration, at least on my track.

The winner of last weeks Wednesday night GTP race, at my track, keeps real exact info on all his equipment.

He set a new distance record, albeit with a small field, with what he told me was the 19th race on his Retro Hawk motor.
(8-2 minute heats, 12.2V)

I've raced F7 and H7 motors and my experience is their prime performance is when brand new and lasts for maybe 30-60min, even though they may actually last longer, they lose performance and badly lose brakes when hot (particularly F7)

They were smoother and nicer to drive though

Much harder brushes on the Retro Hawk.

Of course it would be great if they had brakes as good as the 4002FK, but obviously they are a different animal.

The PS4002FK motor is cheaper than a pair of mounted tyres

[steve37]

Nothing wrong with the PS4002FK, only ones ive seen have issues like to push the boundarys and expect performance well above its intent.

And they outlast a set of tyres by a long shot as per above, and who ever did the prep on that motor really knows what hes doing from what i can see

I certainly respect your opinion but think it more more attributable to good fortune than the motor quality. As for boundary pushing I believe that's called "racing" and is a required activity unless you're happy to run mid to rear of the pack.

There's something to think about.

And those who play with them try to make silk purses from sows ears.

[swodem]

But we're racing sows ears....

When all you're allowed is a sow's ear you have to do the best you can with it. To continue your metaphor, when the sow's ears are so crooked it can't hear the dinner bell, Farmer Brown needs to straighten the ears before he loses the sow.

Capisci?
