    They would definitely assist braking both with friction and improved conductivity of braking voltage. No change in gearing?

    The PS4002FK is.....

    What it is, deal with it we have had worse in the past with other motors it will never be a Grp12 it is however overall pretty dam good.

    Spend less time trying to reinvent the wheel and more time turning it, that magic bean wont compensate for a bad driver.

    Yes, Pro Slot sells brass hardware replacements. I have used them on Gp-12 Retro-Pro motors with good results. Of coarse this may not be legal in all the classes this motor is used in. And it has found a home in everything from Wing cars to FCR Hardbodies and everything in between.

    Yes. All their 4000 series parts interchange. I even used them on a JK Hawk set-up that I loaded a custom Havlecik 38t/27 arm into. Here is the part no. :

    PS-641
    Brush Hood & Heat Sink set
    $3.98

    And you can just call me Sam.

    Thanks for the information. That is exactly what I was looking for.

    Have an amazing day.

    So that's how you qualified so fast at the Port Jeff Retro races.

    Cheers

    I think a lot of the criticism of this motor comes from the politics of retro racing.
    More than one BOD member of IRRA has made disparaging remarks about them.
    If Swiss thinks they're so bad why did he just get 10 more this week?
    These motors are excellent.

    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?

    That's the JK Hawk not a Hawk Retro. Ray Charles would spot that in tech.

    I wish there was a class where these two motors could be run. No seals. These mini-motors are great platforms for some interesting builds. That H-Power Hawk is in an old Eurosport chassis. Just a fun car. Also have a Gp-12 Retro-Pro motor in a GT-12 car.

    Ron runs a class in his RETRO series that runs built PDs. Puts an end to the whining about seals. Lets anyone fix any of the minor flaws in these Chinese set-ups.

    So you buy a new $200 G12 motor, heat cycle it a race or two, then strip it down, com true, reassemble and assess its characteristics. Variety is a given. Yet it's expected $13 FK motors should all be exactly the same. ???

    I am no magician and my cars are always fast with these motors.
    The brush hoods have never given me any problems.
    I just break them in on my Koford power supply and run them.
    Mine run warm the way I gear them and I put the car on a fan between heats.

    Never thrown a winding or burned one up yet.
    I have seen a couple magnets come loose and start rubbing the arm.

    I spend quite a bit of time trying different gear ratios and tire sizes.
    My cars handle well and I pass most guys in the turns, not in the bank.

    When we ran Falcons and Hawk7's guys were buying new motors every week.
    I tried a Retro Hawk and it seemed no different than an average Falcon to me.

    If JK had a sealed version of the Hawk6 that was the same spec I think it would be a better motor than the RH.

    If it were up to me we would all be racing something faster but I doubt many guys would spend much more money for a motor where I race and if we ran anything faster we would just have more crashing anyway.

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